Technical analysis is all about studying stock price graphs
and a few momentum oscillators derived thereof. It must be understood thattechnical studies are based entirely on prices and do not include balance sheets, P&L accounts
(fundamental analysis), the assumption being that the markets are efficient and all possible price sensitive information is built into the price graph of a security / index.
Therefore, technical analysis supports the efficient market theory as against the "random walk theory" which supports the belief that stocks can be bought / sold on random events like
flipping a coin!!!Technical analysis is more dynamic as compared to fundamentalanalysis based on one simple argument - fundamental analysts depend on corporate events like quarterly
results and special announcements like earnings guidance and policy changes in operations to generate a buy / sell recommendation.
If fundamental analysis was the single most reliable indicator of trends, prices would predominantly fluctuate only 4 - 5 times a year - around quarterly results and special announcements
like mergers and acquisitions etc!! Why would prices fluctuate almost daily? If the prices fluctuate ever so often, is there a way to forecast them? Yes according
to technical analysis!!
A price chart is a sequence of prices plotted over a specific time frame. In statistical terms, charts are referred to as time series plots.
On the chart, the y-axis (vertical axis) represents the price scale and the x-axis (horizontal axis) represents the time scale. Prices are plotted from left to right across the x-axis with the most recent plot being the furthest right. The price plot for IBM extends from January 1, 1999 to March 13, 2000.
Technicians, technical analysts and chartists use charts to analyze a wide array of securities and forecast future price movements. The word “securities” refers to any tradable financial instrument or quantifiable index such as stocks, bonds, commodities, futures or market indices. Any security with price data over a period of time can be used to form a chart for analysis.
While technical analysts use charts almost exclusively, the use of charts is not limited to just technical analysis. Because charts provide an easy-to-read graphical representation of a security's price movement over a specific period of time, they can also be of great benefit to fundamental analysts. A graphical historical record makes it easy to spot the effect of key events on a security's price, its performance over a period of time and whether it's trading near its highs, near its lows, or in between.
The time frame used for forming a chart depends on the compression of the data: intraday, daily, weekly, monthly, quarterly or annual data. The less compressed the data is, the more detail is displayed.
Daily data is made up of intraday data that has been compressed to show each day as a single data point, or period. Weekly data is made up of daily data that has been compressed to show each week as a single data point. The difference in detail can be seen with the daily and weekly chart comparison above. 100 data points (or periods) on the daily chart is equal to the last 5 months of the weekly chart, which is shown by the data marked in the rectangle. The more the data is compressed, the longer the time frame possible for displaying the data. If the chart can display 100 data points, a weekly chart will hold 100 weeks (almost 2 years). A daily chart that displays 100 days would represent about 5 months. There are about 20 trading days in a month and about 252 trading days in a year. The choice of data compression and time frame depends on the data available and your trading or investing style.
We will be explaining the construction of line, bar, candlestick and point & figure charts. Although there are other methods available, these are 4 of the most popular methods for displaying price data.
Some investors and traders consider the closing level to be more important than the open, high or low. By paying attention to only the close, intraday swings can be ignored. Line charts are also used when open, high and low data points are not available. Sometimes only closing data are available for certain indices, thinly traded stocks and intraday prices.
Perhaps the most popular charting method is the bar chart. The high, low and close are required to form the price plot for each period of a bar chart. The high and low are represented by the top and bottom of the vertical bar and the close is the short horizontal line crossing the vertical bar. On a daily chart, each bar represents the high, low and close for a particular day. Weekly charts would have a bar for each week based on Friday's close and the high and low for that week.
Bar charts can also be displayed using the open, high, low and close. The only difference is the addition of the open price, which is displayed as a short horizontal line extending to the left of the bar. Whether or not a bar chart includes the open depends on the data available.
Bar charts can be effective for displaying a large amount of data. Using candlesticks, 200 data points can take up a lot of room and look cluttered. Line charts show less clutter, but do not offer as much detail (no high-low range). The individual bars that make up the bar chart are relatively skinny, which allows users the ability to fit more bars before the chart gets cluttered. If you are not interested in the opening price, bar charts are an ideal method for analyzing the close relative to the high and low. In addition, bar charts that include the open will tend to get cluttered quicker. If you are interested in the opening price, candlestick charts probably offer a better alternative.
Originating in Japan over 300 years ago, candlestick charts have become quite popular in recent years. For a candlestick chart, the open, high, low and close are all required. A daily candlestick is based on the open price, the intraday high and low, and the close. A weekly candlestick is based on Monday's open, the weekly high-low range and Friday's close.
Many traders and investors believe that candlestick charts are easy to read, especially the relationship between the open and the close. White (clear) candlesticks form when the close is higher than the open and black (solid) candlesticks form when the close is lower than the open. The white and black portion formed from the open and close is called the body (white body or black body). The lines above and below are called shadows and represent the high and low.
All the charting methods shown above plot one data point for each period of time. No matter how much price movement, each day or week represented is one point, bar, or candlestick along the time scale. Even if the price is unchanged from day to day or week to week, a dot, bar, or candlestick is plotted to mark the price action. Contrary to this methodology, point & figure charts are based solely on price movement, and do not take time into consideration. There is an x-axis but it does not extend evenly across the chart.
The beauty of point & figure charts is their simplicity. Little or no price movement is deemed irrelevant and therefore not duplicated on the chart. Only price movements that exceed specified levels are recorded. This focus on price movement makes it easier to identify support and resistance levels, bullish breakouts and bearish breakdowns. This P&F article has a more detailed explanation of point & figure charts.
There are two methods for displaying the price scale along the y-axis: arithmetic and logarithmic. An arithmetic scale displays 10 points (or dollars) as the same vertical distance no matter what the price level. Each unit of measure is the same throughout the entire scale. If a stock advances from 10 to 80 over a 6-month period, the move from 10 to 20 will appear to be the same distance as the move from 70 to 80. Even though this move is the same in absolute terms, it is not the same in percentage terms.
A logarithmic scale measures price movements in percentage terms. An advance from 10 to 20 would represent an increase of 100%. An advance from 20 to 40 would also be 100%, as would an advance from 40 to 80. All three of these advances would appear as the same vertical distance on a logarithmic scale. Most charting programs refer to the logarithmic scale as a semi-log scale, because the time axis is still displayed arithmetically.
The chart above uses the 4th-Quarter performance of VeriSign to illustrate the difference in scaling. On the log scale version, the distance between 50 and 100 is the same as the distance between 100 and 200. However, on the arithmetic scale, the distance between 100 and 200 is significantly greater than the distance between 50 and 100.
Key points on the benefits of arithmetic and log scale charts:
Even though many different charting techniques are available, one method is not necessarily better than the other. The data may be the same, but each method will provide its own unique interpretation, with its own benefits and drawbacks. A breakout on the point & figure chart may not occur in unison with a breakout in a candlestick chart. Signals that are available on candlestick charts may not appear on bar charts. How the security's price is displayed, be it a bar chart or candlestick chart, with an arithmetic scale or semi-log scale, is not the most important aspect. After all, the data is the same and price action is price action. When all is said and done, it is the analysis of the price action that separates successful technicians from not-so-successful technicians. The choice of which charting method to use will depend on personal preferences and trading or investing styles. Once you have chosen a particular charting methodology, it is probably best to stick with it and learn how best to read the signals. Switching back and forth may cause confusion and undermine the focus of your analysis. Faulty analysis is rarely caused by the chart. Before blaming your charting method for missing a signal, first look at your analysis.
The keys to successful chart analysis are dedication, focus, and consistency:
Support and resistance represent key junctures where the forces of supply and demand meet. In the financial markets, prices are driven by excessive supply (down) and demand (up). Supply is synonymous with bearish, bears and selling. Demand is synonymous with bullish, bulls and buying. These terms are used interchangeably throughout this and other articles. As demand increases, prices advance and as supply increases, prices decline. When supply and demand are equal, prices move sideways as bulls and bears slug it out for control.
Support is the price level at which demand is thought to be strong enough to prevent the price from declining further. The logic dictates that as the price declines towards support and gets cheaper, buyers become more inclined to buy and sellers become less inclined to sell. By the time the price reaches the support level, it is believed that demand will overcome supply and prevent the price from falling below support.
Support does not always hold and a break below support signals that the bears have won out over the bulls. A decline below support indicates a new willingness to sell and/or a lack of incentive to buy. Support breaks and new lows signal that sellers have reduced their expectations and are willing sell at even lower prices. In addition, buyers could not be coerced into buying until prices declined below support or below the previous low. Once support is broken, another support level will have to be established at a lower level.
Support levels are usually below the current price, but it is not uncommon for a security to trade at or near support. Technical analysis is not an exact science and it is sometimes difficult to set exact support levels. In addition, price movements can be volatile and dip below support briefly. Sometimes it does not seem logical to consider a support level broken if the price closes 1/8 below the established support level. For this reason, some traders and investors establish support zones.
Resistance is the price level at which selling is thought to be strong enough to prevent the price from rising further. The logic dictates that as the price advances towards resistance, sellers become more inclined to sell and buyers become less inclined to buy. By the time the price reaches the resistance level, it is believed that supply will overcome demand and prevent the price from rising above resistance.
Resistance does not always hold and a break above resistance signals that the bulls have won out over the bears. A break above resistance shows a new willingness to buy and/or a lack of incentive to sell. Resistance breaks and new highs indicate buyers have increased their expectations and are willing to buy at even higher prices. In addition, sellers could not be coerced into selling until prices rose above resistance or above the previous high. Once resistance is broken, another resistance level will have to be established at a higher level.
Resistance levels are usually above the current price, but it is not uncommon for a security to trade at or near resistance. In addition, price movements can be volatile and rise above resistance briefly. Sometimes it does not seem logical to consider a resistance level broken if the price closes 1/8 above the established resistance level. For this reason, some traders and investors establish resistance zones.
Support and resistance are like mirror images and have many common characteristics.
Support can be established with the previous reaction lows. Resistance can be established by using the previous reaction highs.
The above chart for Halliburton (HAL) shows a large trading range between Dec-99 and Mar-00. Support was
established with the October low around 31. In December, the stock returned to support in the mid-thirties and formed a low around 33. Finally, in February the stock again returned to the support
scene and formed a low around 32 1/2.
After each bounce off support, the stock traded all the way up to resistance. Resistance was first established by the September support break at 42.5. After a support level is broken, it can turn into a resistance level. From the October lows, the stock advanced to the new support-turned-resistance level around 42.5. When the stock failed to advance past 42.5, the resistance level was confirmed. The stock subsequently traded up to 42.5 two more times after that and failed to surpass resistance both times.
Another principle of technical analysis stipulates that support can turn into resistance and vice versa. Once the price breaks below a support level, the broken support level can turn into resistance. The break of support signals that the forces of supply have overcome the forces of demand. Therefore, if the price returns to this level, there is likely to be an increase in supply, and hence resistance.
The other turn of the coin is resistance turning into support. As the price advances above resistance, it signals changes in supply and demand. The breakout above resistance proves that the forces of demand have overwhelmed the forces of supply. If the price returns to this level, there is likely to be an increase in demand and support will be found.
In this example of the NASDAQ 100 Index ($NDX), the stock broke resistance at 935 in May-97 and traded just above this
resistance level for over a month. The ability to remain above resistance established 935 as a new support level. The stock subsequently rose to 1150, but then fell back to test support at 935. After
the second test of support at 935, this level is well established.
From the PeopleSoft (PSFT) example, we can see that support can turn into resistance and then back
into support. PeopleSoft found support at 18 from Oct-98 to Jan-99 (green oval), but broke below support in Mar-99 as the bears overpowered the bulls. When the stock rebounded (red oval), there was
still overhead supply at 18 and resistance was met from Jun-99 to Oct-99.
Where does this overhead supply come from? Demand was obviously increasing around 18 from Oct-98 to Mar-99 (green oval). Therefore, there were a lot of bullish buyers of the stock around 18. When the price declined below 18 and fell to around 14, many of these (now unhappy) bulls were probably still holding the stock. This left a supply overhang (commonly known as resistance) around 18. When the stock rebounded to 18, many of the green-oval-bulls probably took the opportunity to sell and “escape” with little to no loss. When this supply was exhausted, the demand was able to overpower supply and advance above resistance at 18.
Trading ranges can play an important role in determining support and resistance as turning points or as continuation patterns. A trading range is a period of time when prices move within a relatively tight range. This signals that the forces of supply and demand are evenly balanced. When the price breaks out of the trading range, above or below, it signals that a winner has emerged. A break above is a victory for the bulls (demand) and a break below is a victory for the bears (supply).
After an extended advance from 27 to 64, WorldCom (WCOM) entered into a trading range between 55 and 63 for about 5 months. There
was a false breakout in mid-June when the stock briefly poked its head above 62 (red oval). This did not last long and a gap down a few days later nullified the breakout (black arrow). The stock then
proceeded to break support at 55 in Aug-99 and trade as low as 50. Here is another example of support turned resistance as the stock bounced off 55 two more times before heading lower. While this
does not always happen, a return to the new resistance level offers a second chance for longs to get out and shorts to enter the fray.
In Nov/Dec-99, Lucent Technologies (LU) formed a trading range that resembled a head and shoulders pattern (red
oval). When the stock broke support at 60, there was little or no time to exit. Even though there is a long black candlestick indicating an open at 59, the stock fell so fast that it was impossible
to exit above 44. In hindsight, the support line could have been drawn as an upward sloping neckline (blue line), and the support break would have come at 61. This is only 1 point higher and a trader
would have had to take action immediately to avoid a sharp fall. However, the lows match up rather nicely on the neckline, and it is something to consider when drawing support lines.
After Lucent declined, a trading range was established between 40.5 and 47.5 for almost two months (green oval). The resistance level of the trading range was well marked by three reaction peaks at 47.5. The support level was not as clearly marked, but appeared to be between 40 and 41. Some buying interest began to become evident around 44 in mid- to late-February. Notice the array of candlesticks with long lower shadows, or hammers, as they are known. The stock then proceeded to form two up gaps on 24-Feb and 25-Feb, and finally closed above resistance at 48. This was a clear indication of demand winning out over supply. There were still two more opportunities (days) to get in on the action. On the third day after the breakout, the stock gapped up and moved above 56.
Because technical analysis is not an exact science, it is useful to create support and resistance zones. This is contrary to the strategy mapped out for Lucent Technologies (LU), but it is sometimes the case. Each security has its own characteristics, and analysisshould reflect the intricacies of the security. Sometimes, exact support and resistance levels are best, and, sometimes, zones work better. Generally, the tighter the range, the more exact the level. If the trading range spans less than 2 months and the price range is relatively tight, then more exact support and resistance levels are best suited. If a trading range spans many months and the price range is relatively large, then it is best to use support and resistance zones. These are only meant as general guidelines, and each trading range should be judged on its own merits.
Returning to the analysis of Halliburton (HAL), we can see that the November high of the trading range (32 to 44) extended more
than 20% past the October low, making the range quite large relative to the price. Because the September support break forms our first resistance level, we are ready to set up a resistance zone after
the November high is formed, probably around early December. At this point though, we are still unsure if a large trading range will develop. The subsequent low in December, which was just higher
than the October low, offers evidence that a trading range is forming, and we are ready to set the support zone. As long as the stock trades within the boundaries set by the support and resistance
zone, we will consider the trading range to be valid. Support may be looked upon as an opportunity to buy, and resistance as an opportunity to sell.
Identification of key support and resistance levels is an essential ingredient to successfultechnical analysis. Even though it is sometimes difficult to establish exact support and resistance levels, being aware of their existence and location can greatly enhanceanalysis and forecasting abilities. If a security is approaching an important support level, it can serve as an alert to be extra vigilant in looking for signs of increased buying pressure and a potential reversal. If a security is approaching a resistance level, it can act as an alert to look for signs of increased selling pressure and potential reversal. If a support or resistance level is broken, it signals that the relationship between supply and demand has changed. A resistance breakout signals that demand (bulls) has gained the upper hand and a support break signals that supply (bears) has won the battle.
Technical analysis is built on the assumption that prices trend. Trend Lines are an important tool in technical analysis for both trend identification and confirmation. A trend line is a straight line that connects two or more price points and then extends into the future to act as a line of support or resistance. Many of the principles applicable to support and resistance levels can be applied to trend lines as well. It is important that you understand all of the concepts presented in our Support and Resistance article before you continue.
An uptrend line has a positive slope and is formed by connecting two or more low points. The second low must be higher than the first for the line to have a positive slope. Uptrend lines act as support and indicate that net-demand (demand less supply) is increasing even as the price rises. A rising price combined with increasing demand is very bullish, and shows a strong determination on the part of the buyers. As long as prices remain above the trend line, the uptrend is considered solid and intact. A break below the uptrend line indicates that net-demand has weakened and a change in trend could be imminent.
A downtrend line has a negative slope and is formed by connecting two or more high points. The second high must be lower than the first for the line to have a negative slope. Downtrend lines act as resistance, and indicate that net-supply (supply less demand) is increasing even as the price declines. A declining price combined with increasing supply is very bearish, and shows the strong resolve of the sellers. As long as prices remain below the downtrend line, the downtrend is solid and intact. A break above the downtrend line indicates that net-supply is decreasing and that a change of trend could be imminent.
For a detailed explanation of trend changes, which are different than just trend line breaks, please see our article on the Dow Theory.
High points and low points appear to line up better for trend lines when prices are displayed using a semi-log scale. This is especially true when long-term trend lines are being drawn or when there is a large change in price. Most charting programs allow users to set the scale as arithmetic or semi-log. An arithmetic scale displays incremental values (5,10,15,20,25,30) evenly as they move up the y-axis. A $10 movement in price will look the same from $10 to $20 or from $100 to $110. A semi-log scale displays incremental values in percentage terms as they move up the y-axis. A move from $10 to $20 is a 100% gain, and would appear to be a much larger than a move from $100 to $110, which is only a 10% gain.
In the case of EMC, there was a large price change over a long period of time. While there were not
any false breaks below the uptrend line on the arithmetic scale, the rate of ascent appears smoother on the semi-log scale. EMC doubled three times in less than two years. On the semi-log scale, the
trend line fits all the way up. On the arithmetic scale, three different trend lines were required to keep pace with the advance.
In the case of Amazon.com (AMZN), there were two false breaks above the downtrend line as the stock declined
during 2000 and 2001. These false break outs could have led to premature buying as the stock continued to decline after each one. The stock lost 60% of its value three times over a two year period.
The semi-log scale reflects the percentage loss evenly, and the downtrend line was never broken.
It takes two or more points to draw a trend line. The more points used to draw the trend line, the more validity attached to the support or resistance level represented by the trend line. It can sometimes be difficult to find more than 2 points from which to construct a trend line. Even though trend lines are an important aspect of technical analysis, it is not always possible to draw trend lines on every price chart. Sometimes the lows or highs just don't match up, and it is best not to force the issue. The general rule in technicalanalysis is that it takes two points to draw a trend line and the third point confirms the validity.
The chart of Microsoft (MSFT) shows an uptrend line that has been touched 4 times. After the third touch
in Nov-99, the trend line was considered a valid line of support. Now that the stock has bounced off of this level a fourth time, the soundness of the support level is enhanced even more. As long as
the stock remains above the trend line (support), the trend will remain in control of the bulls. A break below would signal that net-supply was increasing and that a change in trend could be
imminent.
The lows used to form an uptrend line and the highs used to form a downtrend line should not be too far apart, or too close together. The most suitable distance apart will depend on the time frame, the degree of price movement, and personal preferences. If the lows (highs) are too close together, the validity of the reaction low (high) may be in question. If the lows are too far apart, the relationship between the two points could be suspect. An ideal trend line is made up of relatively evenly spaced lows (or highs). The trend line in the above MSFT example represents well-spaced low points.
On the Wal-Mart (WMT) example, the second high point appears to be too close to the first high
point for a valid trend line; however, it would be feasible to draw a trend line beginning at point 2 and extending down to the February reaction high.
As the steepness of a trend line increases, the validity of the support or resistance level decreases. A steep trend line results from a sharp advance (or decline) over a brief period of time. The angle of a trend line created from such sharp moves is unlikely to offer a meaningful support or resistance level. Even if the trend line is formed with three seemingly valid points, attempting to play a trend line break or to use the support and resistance level established it will often prove difficult.
The trend line for Yahoo! (YHOO) was touched four times over a 5-month period. The spacing between the
points appears OK, but the steepness of the trend line is unsustainable, and the price is more likely than not to drop below the trend line. However, trying to time this drop or make a play after the
trend line is broken is a difficult task. The amount of data displayed and the size of the chart can also affect the angle of a trend line. Short and wide charts are less likely to have steep trend
lines than long and narrow charts. Keep that in mind when assessing the validity and sustainability of a trend line.
Sometimes there appears to be the possibility for drawing a trend line, but the exact points do not match up cleanly. The highs or lows might be out of whack, the angle might be too steep or the points might be too close together. If one or two points could be ignored, then a fitted trend line could be formed. With the volatility present in the market, prices can over-react, and produce spikes that distort the highs and lows. One method for dealing with over-reactions is to draw internal trend lines. Even though an internal trend line ignores price spikes, the ignoring should be within reason.
The long-term trend line for the S&P 500 ($SPX) extends up from the end of 1994, and passes through low points in Jul-96,
Sept-98 and Oct-98. These lows were formed with selling climaxes, and represented extreme price movements that protrude beneath the trend line. By drawing the trend line through the lows, the line
appears to be at a reasonable angle, and the other lows match up extremely well.
Sometimes, there is a price cluster with a high or low spike sticking out. A price cluster is an area where prices are grouped within a tight range over a period of
time. The price cluster can be used to draw the trend line, and the spike can be ignored. The Coca Cola (KO) chart shows an internal trend line that is formed by ignoring price spikes
and using the price clusters, instead. In October and November 1998, Coke formed a peak, with the November peak just higher than the October peak (red arrow). If the November peak had been used to
draw a trend line, then the slope would have been more negative, and there would have appeared to be a breakout in Dec-98 (gray line). However, this would have only been a two-point trend line,
because the May-June highs are too close together (black arrows). Once the Dec-99 peak formed (green arrow), it would have been possible to draw an internal trend line based on the price clusters
around the Oct/Nov-98 and the Dec-99 peaks (blue line). This trend line is based on three solid touches, and it accurately forecasts resistance in Jan-00 (blue arrow).
Trend lines can offer great insight, but if used improperly, they can also produce false signals. Other items - such as horizontal support and resistance levels or peak-and-trough analysis - should be employed to validate trend line breaks. While trend lines have become a very popular aspect of technical analysis, they are merely one tool for establishing, analyzing, and confirming a trend. Trend lines should not be the final arbiter, but should serve merely as a warning that a change in trend may be imminent. By using trend line breaks for warnings, investors and traders can pay closer attention to other confirming signals for a potential change in trend.
The uptrend line for VeriSign (VRSN) was touched 4 times, and seemed to be a valid support level. Even though
the trend line was broken in Jan-00, the previous reaction low held, and did not confirm the trend line break. In addition, the stock recorded a new higher high prior to the trend line break.
Have you ever wondered what causes gaps in price charts and what they mean? Well, you've come to the right place. Just in case, a gap is an area on a price chart in which there were no trades. Normally this occurs between the close of the market on one day and the next day's open. Lot's of things can cause this, such as an earnings report coming out after the stock market has closed for the day. If the earnings were significantly higher than expected, many investors might place buy orders for the next day. This could result in the price opening higher than the previous day's close. If the trading that day continues to trade above that point, a gap will exist in the price chart. Gaps can offer evidence that something important has happened to the fundamentals or the psychology of the crowd that accompanies this market movement. Before we get into the different types of gaps, here is a chart showing a gap so you will know what we are talking about.
Gaps appear more frequently on daily charts, where every day is an opportunity to create an opening gap. Gaps on weekly or monthly charts are fairly rare: the gap would have to occur between Friday's close and Monday's open for weekly charts and between the last day of the month's close and the first day of the next month's for the monthly charts. Gaps can be subdivided into four basic categories: Common, Breakaway, Runaway, and Exhaustion.
Sometimes referred to as a trading gap or an area gap, the common gap is usually uneventful. In fact, they can be caused by a stock going ex-dividend when the trading volume is low. These gaps are common (get it?) and usually get filled fairly quickly. ”Getting filled” means that the price action at a later time (few days to a few weeks) usually retraces at the least to the last day before the gap. This is also known as closing the gap. Here is a chart of two common gaps that have been filled. Notice that after the gap the prices have come down to at least the beginning of the gap? That is called closing or filling the gap.
A common gap usually appears in a trading range or congestion area, and reinforces the apparent lack of interest in the stock at that time. Many times this is further exacerbated by low trading volume. Being aware of these types of gaps is good, but doubtful that they will produce a trading opportunities.
Breakaway gaps are the exciting ones. They occur when the price action is breaking out of their trading range or congestion area. To understand gaps, one has to understand the nature of congestion areas in the market. A congestion area is just a price range in which the market has traded for some period of time, usually a few weeks or so. The area near the top of the congestion area is usually resistance when approached from below. Likewise, the area near the bottom of the congestion area is support when approached from above. To break out of these areas requires market enthusiasm and, either, many more buyers than sellers for upside breakouts or more sellers than buyers for downside breakouts.
Volume will (should) pick up significantly, for not only the increased enthusiasm, but many are holding positions on the wrong side of the breakout and need to cover or sell them. It is better if the volume does not happen until the gap occurs. This means that the new change in market direction has a chance of continuing. The point of breakout now becomes the new support (if an upside breakout) or resistance (if a downside breakout). Don't fall into the trap of thinking this type of gap, if associated with good volume, will be filled soon. It might take a long time. Go with the fact that a new trend in the direction of the stock has taken place, and trade accordingly. Notice in the chart below how prices spent over 2 months without going lower than about 41. When they did, it was with increased volume and a downward breakaway gap.
A good confirmation for trading gaps is if they are associated with classic chart patterns. For example, if an ascending triangle suddenly has a breakout gap to the upside, this can be a much better trade than a breakaway gap without a good chart pattern associated with it. The chart below shows the normally bullish ascending triangle (flat top and rising, lower trend line) with a breakaway gap to the upside, as you would expect with an ascending triangle.
Runaway gaps are also called measuring gaps, and are best described as gaps that are caused by increased interest in the stock. For runaway gaps to the upside, it usually represents traders who did not get in during the initial move of the up trend and while waiting for a retracement in price, decided it was not going to happen. Increased buying interest happens all of a sudden, and the price gaps above the previous day's close. This type of runaway gap represents an almost panic state in traders. Also, a good uptrend can have runaway gaps caused by significant news events that cause new interest in the stock. In the chart below, note the significant increase in volume during and after the runaway gap.
Runaway gaps can also happen in downtrends. This usually represents increased liquidation of that stock by traders and buyers who are standing on the sidelines. These can become very serious as those who are holding onto the stock will eventually panic and sell – but sell to whom? The price has to continue to drop and gap down to find buyers. Not a good situation.
The term measuring gap is also used for runaway gaps. This is an interpretation that is hard to find examples for, but it is a way of helping one decide how much longer a trend will last. The theory is that the measuring gap will occur in the middle of, or half way through, the move.
Sometimes, the futures market will have runaway gaps that are caused by trading limits imposed by the exchanges. Getting caught on the wrong side of the trend when you have these limit moves in futures can be horrifying. The good news is that you can also be on the right side of them. These are not common occurrences in the futures market despite all the wrong information being touted by those who do not understand it, and are only repeating something they read from an uninformed reporter.
Exhaustion gaps are those that happen near the end of a good up- or downtrend. They are many times the first signal of the end of that move. They are identified by high volume and large price difference between the previous day's close and the new opening price. They can easily be mistaken for runaway gaps if one does not notice the exceptionally high volume.
It is almost a state of panic if the gap appears during a long down move where pessimism has set in. Selling all positions to liquidate holdings in the market is not uncommon. Exhaustion gaps are quickly filled as prices reverse their trend. Likewise, if they happen during a bull move, some bullish euphoria overcomes trades, and buyers cannot get enough of that stock. The prices gap up with huge volume; then, there is great profit taking and the demand for the stock totally dries up. Prices drop, and a significant change in trend occurs. Exhaustion gaps are probably the easiest to trade and profit from. In the chart, notice that there was one more day of trading to the upside before the stock plunged. The high volume was the giveaway that this was going to be, either, an exhaustion gap or a runaway gap. Because of the size of the gap and the near doubling of volume, an exhaustion gap was in the making here.
There is an old saying that the market abhors a vacuum and all gaps will be filled. While this may have some merit for common and exhaustion gaps, holding positions waiting for breakout or runaway gaps to be filled can be devastating to your portfolio. Likewise, waiting to get on-board a trend by waiting for prices to fill a gap can cause you to miss the big move. Gaps are a significant technical development in price action and chart analysis, and should not be ignored. Japanese candlestick analysis is filled with patterns that rely on gaps to fulfill their objectives.
There are hundreds of thousands of market participants buying and selling securities for a wide variety of reasons: hope of gain, fear of loss, tax consequences, short-covering, hedging, stop-loss triggers, price target triggers, fundamental analysis, technical analysis, broker recommendations and a few dozen more. Trying to figure out why participants are buying and selling can be a daunting process. Chart patterns put all buying and selling into perspective by consolidating the forces of supply and demand into a concise picture. As a complete pictorial record of all trading, chart patterns provide a framework toanalyze the battle raging between bulls and bears. More importantly, chart patterns andtechnical analysis can help determine who is winning the battle, allowing traders and investors to position themselves accordingly.
In many ways, chart patterns are simply more complex versions of trend lines. It is important that you read and understand our articles on Support and Resistance as well as Trend Lines before you continue.
Chart pattern analysis can be used to make short-term or long-term forecasts. The data can be intraday, daily, weekly or monthly and the patterns can be as short as one day or as long as many years. Gaps and outside reversals may form in one trading session, while broadening tops and dormant bottoms may require many months to form.

Much of our understanding of chart patterns can be attributed to the work of Richard Schabacker. His 1932 classic, Technical Analysis and Stock Market Profits, laid the foundations for modern pattern analysis. InTechnical Analysis of Stock Trends (1948), Edwards and Magee credit Schabacker for most of the concepts put forth in the first part of their book. We would also like to acknowledge Messrs. Schabacker, Edwards and Magee, and John Murphy as the driving forces behind these articles and our understanding of chart patterns.
Pattern analysis may seem straightforward, but it is by no means an easy task. Schabacker states:
Even though Schabacker refers to “the science of chart reading”, technical analysis can at times be less science and more art. In addition, pattern recognition can be open to interpretation, which can be subject to personal biases. To defend against biases and confirm pattern interpretations, other aspects of technical analysis should be employed to verify or refute the conclusions drawn. While many patterns may seem similar in nature, no two patterns are exactly alike. False breakouts, bogus reads and exceptions to the rule are all part of the ongoing education.
Careful and constant study are required for successful chart analysis. On the AMZN chart above, the stock broke resistance from a head and shoulders reversal. While the trend is now bearish, analysis must continue to confirm the bearish trend.
Novellus (NVLS)
Some analysts might have labeled the NVLS chart as a head and shoulders pattern with neckline support around 17.50. Whether or not this is robust remains open to debate. Even though the stock broke neckline support at 17.50, it repeatedly moved back above its support break. This refusal might have been taken as a sign of strength and justified a reassessment of the pattern.
Two basic tenets of technical analysis are that prices trend and that history repeats itself. An uptrend indicates that the forces of demand (bulls) are in control and a downtrend that the forces of supply (bears) are in control. However, prices do not trend forever and as the balance of power shifts, a chart pattern begins to emerge. Certain patterns, such as a parallel channel, denote a strong trend. However, the vast majority of chart patterns fall into two main groups: reversal and continuation. Reversal patterns indicate a change of trend and can be broken down into top and bottom formations. Continuation patterns indicate a pause in trend and indicate that the previous direction will resume after a period of time.

Just because a pattern forms after a significant advance or decline does not mean it is a reversal pattern. Many patterns, such as a rectangle, can be classified as either reversal or continuation. Much depends on the previous price action, volume and other indicators as the pattern evolves. This is where the science of technical analysis becomes the art oftechnical analysis.
Below is a list of common chart patterns that can be useful in Technical Analysis. Please see the Introduction to Chart Patterns article for more details on how to use chart patterns when analysing a chart.
The Double Top Reversal is a bearish reversal pattern typically found on bar charts, line charts and candlestick charts. As its name implies, the pattern is made up of two consecutive peaks that are roughly equal, with a moderate trough in-between. Note that a Double Top Reversal on a bar or line chart is completely different from Double Top Breakout on a P&F chart. Namely, Double Top Breakouts on P&F charts are bullish patterns that mark an upside resistance breakout.
Although there can be variations, the classic Double Top Reversal marks at least an intermediate change, if not a long-term change, in trend from bullish to bearish. Many potential Double Top Reversals can form along the way up, but until key support is broken, a reversal cannot be confirmed. To help clarify, we will look at the key points in the formation and then walk through an example.

Many potential Double Top Reversals can form along the way up, but until key support is broken, a reversal cannot be confirmed. To help clarify, we will look at the key points in the formation and then walk through an example.
While the Double Top Reversal formation may seem straightforward, technicians should take proper steps to avoid deceptive Double Top Reversals. The peaks should be separated by about a month. If the peaks are too close, they could just represent normal resistance rather than a lasting change in the supply/demand picture. Ensure that the low between the peaks declines at least 10%. Declines less than 10% may not be indicative of a significant increase in selling pressure. After the decline, analyze the trough for clues on the strength of demand. If the trough drags on a bit and has trouble moving back up, demand could be drying up. When the security does advance, look for a contraction in volume as a further indication of weakening demand.
Perhaps the most important aspect of a Double Top Reversal is to avoid jumping the gun. Wait for support to be broken in a convincing manner, and usually with an expansion of volume. A price or time filter can be applied to differentiate between valid and false support breaks. A price filter might require a 3% support break before validation. A time filter might require the support break to hold for 3 days before considering it valid. The trend is in force until proven otherwise. This applies to the Double Top Reversal as well. Until support is broken in a convincing manner, the trend remains up.
The Double Top Reversal in Ford took about 5 months to form. Even after the support break, there was another test of newfound resistance almost 4 months later.
On the second chart, 30 3/4 marked the support turned resistance level, and 31 marked a 50% retracement of the decline from 36.80 to 25. Combined with the price action in early June and early July, a resistance zone could probably be established between 31 and 32. The stock subsequently formed a lower high at 30 in Jan-00, and declined to around 22 by mid-March.
The Double Bottom Reversal is a bullish reversal pattern typically found on bar charts, line charts and candlestick charts. As its name implies, the pattern is made up of two consecutive troughs that are roughly equal, with a moderate peak in-between. Note that a Double Bottom Reversal on a bar or line chart is completely different from Double Bottom Breakdown on a P&F chart. Namely, Double Bottom Breakdowns on P&F charts are bearish patterns that mark a downside support break.
Although there can be variations, the classic Double Bottom Reversal usually marks an intermediate or long-term change in trend. Many potential Double Bottom Reversals can form along the way down, but until key resistance is broken, a reversal cannot be confirmed. To help clarify, we will look at the key points in the formation and then walk through an example.
It is important to remember that the Double Bottom Reversal is an intermediate to long-term reversal pattern that will not form in a few days. Even though formation in
a few weeks is possible, it is preferable to have at least 4 weeks between lows. Bottoms usually take longer than tops to form and patience can often be a virtue. Give the pattern time to develop and
look for the proper clues. The advance off of the first trough should be 10-20%. The second trough should form a low within 3% of the previous low and volume on the ensuing advance should increase.
Volume indicators such as Chaikin Money Flow, OBV and Accumulation/
After trending lower for almost a year, PFE formed a Double Bottom Reversal and broke resistance with an expansion in volume.
A Head and Shoulders reversal pattern forms after an uptrend, and its completion marks a trend reversal. The pattern contains three successive peaks with the middle peak (head) being the highest and the two outside peaks (shoulders) being low and roughly equal. The reaction lows of each peak can be connected to form support, or a neckline.
As its name implies, the Head and Shoulders reversal pattern is made up of a left shoulder, a head, a right shoulder, and a neckline. Other parts playing a role in the pattern are volume, the breakout, price target andsupport turned resistance. We will look at each part individually, and then put them together with some examples.
Archer Daniels Midland Company (ADM) formed a Head and Shoulders reversal with a slightly upward sloping
neckline. Key points include:
The head and shoulders pattern is one of the most common reversal formations. It is important to remember that it occurs after an uptrend and usually marks a major trend reversal when complete.While it is preferable that the left and right shoulders be symmetrical, it is not an absolute requirement. They can be different widths as well as different heights. Identification of neckline support and volume confirmation on the break can be the most critical factors. The support break indicates a new willingness to sell at lower prices. Lower prices combined with an increase in volume indicate an increase in supply. The combination can be lethal, and sometimes, there is no second chance return to the support break. Measuring the expected length of the decline after the breakout can be helpful, but don't count on it for your ultimate target. As the pattern unfolds over time, other aspects of the technical picture are likely to take precedence.
The Head and Shoulders Bottom, sometimes referred to as an Inverse Head and Shoulders, is a pattern that shares many common characteristics with its comparable partner, but relies more heavily on volume patterns for confirmation.
As a major reversal pattern, the Head and Shoulders Bottom forms after a downtrend, and its completion marks a change in trend. The pattern contains three successive troughs with the middle trough (head) being the deepest and the two outside troughs (shoulders) being shallower. Ideally, the two shoulders would be equal in height and width. The reaction highs in the middle of the pattern can be connected to form resistance, or a neckline.
The price action forming both Head and Shoulders Top and Head and Shoulders Bottom patterns remains roughly the same, but reversed. The role of volume marks the biggest difference between the two. Generally speaking, volume plays a larger role in bottom formations than top formations. While an increase in volume on the neckline breakout for a Head and Shoulders Top is welcomed, it is absolutely required for a bottom. We will look at each part of the pattern individually, keeping volume in mind, and then put the parts together with some examples.
Alaska Air Group, Inc. (ALK) formed a Head and Shoulders Bottom with a downward sloping neckline. Key points include:
AT&T (T) formed a head and shoulders bottom with a flat neckline. The shoulders are a bit shallow, but the neckline and head are well pronounced. Key points include:
Head and Shoulder Bottoms are one of the most common and reliable reversal formations. It is important to remember that they occur after a downtrend and usually mark a major trend reversal when complete.While it is preferable that the left and right shoulders be symmetrical, it is not an absolute requirement. Shoulders can be different widths as well as different heights. Keep in mind that technicalanalysis is more an art than a science. If you are looking for the perfect pattern, it may be a long time coming.
Analysis of the Head and Shoulders Bottom should focus on correct identification of neckline resistance and volume patterns. These are two of the most important aspects to a successful read, and by extension a successful trade. The neckline resistance breakout combined with an increase in volume indicates an increase in demand at higher prices. Buyers are exerting greater force, and the price is being affected.
As seen from the examples, traders do not always have to chase a stock after the neckline breakout. Often, but certainly not always, the price will return to this new support level and offer a second chance to buy. Measuring the expected length of the advance after the breakout can be helpful, but don't count on it for your ultimate target. As the pattern unfolds over time, other aspects of the technical picture are likely to take precedent. Technical analysis is dynamic, and youranalysis should incorporate aspects of the long-, medium- and short-term picture.
The Falling Wedge is a bullish pattern that begins wide at the top and contracts as prices move lower. This price action forms a cone that slopes down as the reaction highs and reaction lows converge. In contrast tosymmetrical triangles, which have no definitive slope and no bias, falling wedges definitely slope down and have a bullish bias. However, this bullish bias cannot be realized until a resistance breakout.
The falling wedge can also fit into the continuation category. As a continuation pattern, the falling wedge will still slope down, but the slope will be against the prevailing uptrend. As a reversal pattern, the falling wedge slopes down and with the prevailing trend. Regardless of the type (reversal or continuation), falling wedges are regarded as bullish patterns.
As with rising wedges, the falling wedge can be one of the most difficult chart patterns to accurately recognize and trade. When lower highs and lower lows form, as in a falling wedge, a security remains in a downtrend.The falling wedge is designed to spot a decrease in downside momentum and alert technicians to a potential trend reversal. Even though selling pressure may be diminishing, demand does not win out until resistance is broken. As with most patterns, it is important to wait for a breakout and combine other aspects of technicalanalysis to confirm signals.
FCX provides a textbook example of a falling wedge at the end of a long downtrend.
The Rising Wedge is a bearish pattern that begins wide at the bottom and contracts as prices move higher and the trading range narrows. In contrast to symmetrical triangles, which have no definitive slope and no bullish or bearish bias, rising wedges definitely slope up and have a bearish bias.
Even though this article will focus on the rising wedge as a reversal pattern, the pattern can also fit into the continuation category. As a continuation pattern, the rising wedge will still slope up, but the slope will be against the prevailing downtrend. As a reversal pattern, the rising wedge will slope up and with the prevailing trend. Regardless of the type (reversal or continuation), rising wedges are bearish.
The rising wedge can be one of the most difficult chart patterns to accurately recognize and trade. While it is a consolidation formation, the loss of upside momentum on each successive high gives the pattern its bearish bias. However, the series of higher highs and higher lows keeps the trend inherently bullish. The final break of support indicates that the forces of supply have finally won out and lower prices are likely. There are no measuring techniques to estimate the decline – other aspects of technical analysis should be employed to forecast price targets.
ANN provides a good example of the rising wedge as a reversal pattern that forms in the face of weakening momentum and money flow.
The Rounding Bottom is a long-term reversal pattern that is best suited for weekly charts. It is also referred to as a saucer bottom, and represents a long consolidation period that turns from a bearish bias to a bullish bias.
A rounding bottom could be thought of as a head and shoulders bottom without readily identifiable shoulders. The head represents the low and is fairly central to the pattern. The volume patterns are similar and confirmation comes with a resistance breakout. While symmetry is preferable on the rounding bottom, the left and right side do not have to be equal in time or slope. The important thing is to capture the essence of the pattern.
AMGN provides an example of a rounding bottom that formed after a long consolidation period. Throughout 1996, the stock traded in a tight range bound by 16.63 and 12.83. The trading range continued the first half of 1997 and the stock broke support by falling to a low of 12 in August.
The Triple Top Reversal is a bearish reversal pattern typically found on bar charts, line charts and candlestick charts. There are three equal highs followed by a break below support. As major reversal patterns, these patterns usually form over a 3 to 6 month period. Note that a Triple Top Reversal on a bar or line chart is completely different from Triple Top Breakout on a P&F chart.. Namely, Triple Top Breakouts on P&F charts are bullish patterns that mark an upside resistance breakout. We will first examine the individual parts of the pattern and then look at an example.
Throughout the development of the Triple Top Reversal, it can start to resemble a number of other patterns. Before the third high forms, the pattern may look like a Double Top Reversal. Three equal highs can also be found in an ascending triangle or rectangle. Of these patterns mentioned, only the ascending triangle has bullish overtones; the others are neutral until a break occurs. In this same vein, the Triple Top Reversal should also be treated as a neutral pattern until a breakdown occurs. The inability to break above resistance is bearish, but the bears have not won the battle until support is broken. Volume on the last decline off resistance can sometimes yield a clue. If there is a sharp increase in volume and momentum, then the chances of a support break increase.
When looking for patterns, it is important to keep in mind that technicalanalysis is more art and less science. Pattern interpretations should be fairly specific, but not overly exacting as to obstruct the spirit of the pattern. A pattern may not fit the description to the letter, but that should not detract from its robustness. For example: it can be difficult to find a Triple Top Reversal with three highs that are exactly equal. However, if the highs are within reasonable proximity and other aspects of the technical analysis picture jibe, it would embody the spirit of a Triple Top Reversal. The spirit is three attempts at resistance, followed by a breakdown below support, with volume confirmation. ROK illustrates an example of a Triple Top Reversal that does not fit exactly, but captures the spirit of the pattern.
The Triple Bottom Reversal is a bullish reversal pattern typically found on bar charts, line charts and candlestick charts. There are three equal lows followed by a break above resistance. As major reversal patterns, these patterns usually form over a 3 to 6 month period. Note that a Triple Bottom Reversal on a bar or line chart is completely different from Triple Bottom Breakdown on a P&F chart. Namely, Triple Bottom Breakouts on P&F charts are bearish patterns that mark a downside support break. We will first examine the individual parts of the pattern and then look at an example.
As the Triple Bottom Reversal develops, it can start to resemble a number of patterns. Before the third low forms, the pattern may look like a Double Bottom Reversal. Three equal lows can also be found in adescending triangle or rectangle. Of these patterns mentioned, only the descending triangle has bearish overtones; the others are neutral until a breakout occurs. Similarly, the Triple Bottom Reversal should also be treated as a neutral pattern until a breakout occurs. The ability to hold support is bullish, but demand has not won the battle until resistance is broken. Volume on the last advance can sometimes yield a clue. If there is a sharp increase in volume and momentum, then the chances of a breakout increase.
After a failed double bottom breakout, ANDW formed a large Triple Bottom Reversal. While the new reaction high (black arrow) and potential double bottom breakout seemed bullish, the stock subsequently fell back to support.
As the name implies, the Bump and Run Reversal (BARR) is a reversal pattern that forms after excessive speculation drives prices up too far, too fast. Developed by Thomas Bulkowski, the pattern was introduced in the June-97 issue of Technical Analysis of Stocks and Commodities and also included in his recently published book, the Encyclopedia of Chart Patterns.
The pattern was originally named the Bump and Run Formation, or BARF. Bulkowski decided that Wall Street was not ready for such an acronym and changed the name to Bump and Run Reversal. Bulkowski identified three main phases to the pattern: lead-in, bump and run. We will examine these phases and also look at volume and pattern validation.
The Bump and Run Reversal pattern can be applied to daily, weekly or monthly charts. As stated above, the pattern is designed to identify speculative advances that are unsustainable for a long period. Because prices rise very fast to form the left side of the bump, the subsequent decline can be just as ferocious.
Level Three Communications (LVLT) formed a Bump and Run Reversal pattern after prices advanced in a speculative frenzy at the beginning of 2000. Prices advanced from 72 to 132 in 2 months and this advance ultimately proved unsustainable.
Flags and Pennants are short-term continuation patterns that mark a small consolidation before the previous move resumes. These patterns are usually preceded by a sharp advance or decline with heavy volume, and mark a mid-point of the move.
Even though flags and pennants are common formations, identification guidelines should not be taken lightly. It is important that flags and pennants are preceded by a sharp advance or decline. Without a sharp move, the reliability of the formation becomes questionable and trading could carry added risk. Look for volume confirmation on the initial move, consolidation and resumption to augment the robustness of pattern identification.
HPQ provides an example of a flag that forms after a sharp and sudden advance.
The symmetrical triangle, which can also be referred to as a coil, usually forms during a trend as a continuation pattern. The pattern contains at least two lower highs and two higher lows. When these points are connected, the lines converge as they are extended and the symmetrical triangle takes shape. You could also think of it as a contracting wedge, wide at the beginning and narrowing over time.
While there are instances when symmetrical triangles mark important trend reversals, they more often mark a continuation of the current trend. Regardless of the nature of the pattern, continuation or reversal, the direction of the next major move can only be determined after a valid breakout. We will examine each part of the symmetrical triangle individually, and then provide an example with Conseco.
Edwards and Magee suggest that roughly 75% of symmetrical triangles are continuation patterns and the rest mark reversals. The reversal patterns can be especially difficult to analyze and often have false breakouts. Even so, we should not anticipate the direction of the breakout, but rather wait for it to happen. Further analysis should be applied to the breakout by looking for gaps, accelerated price movements, and volume for confirmation. Confirmation is especially important for upside breakouts.
Prices sometimes return to the breakout point of apex on a reaction move before resuming in the direction of the breakout. This return can offer a second chance to participate with a better reward to risk ratio. Potential reward price targets found by measurement and parallel trend line extension are only meant to act as rough guidelines. Technical analysis is dynamic and ongoing assessment is required. In the first example above, SUNW may have fulfilled its target (42) in a few months, but the stock gave no sign of slowing down and advanced above 100 in the following months.
Conseco (CNCEQ) formed a rather large symmetrical triangle over a 5-month period before breaking out on the downside.
The ascending triangle is a bullish formation that usually forms during an uptrend as a continuation pattern. There are instances when ascending triangles form as reversal patterns at the end of a downtrend, but they are typically continuation patterns. Regardless of where they form, ascending triangles are bullish patterns that indicate accumulation.
Because of its shape, the pattern can also be referred to as a right-angle triangle. Two or more equal highs form a horizontal line at the top. Two or more rising troughs form an ascending trend line that converges on the horizontal line as it rises. If both lines were extended right, the ascending trend line could act as the hypotenuse of a right triangle. If a perpendicular line were drawn extending down from the left end of the horizontal line, a right triangle would form. Let's examine each individual part of the pattern and then look at an example.
In contrast to the symmetrical triangle, an ascending triangle has a definitive bullish bias before the actual breakout. If you will recall, the symmetrical triangle is a neutral formation that relies on the impending breakout to dictate the direction of the next move. On the ascending triangle, the horizontal line represents overhead supply that prevents the security from moving past a certain level. It is as if a large sell order has been placed at this level and it is taking a number of weeks or months to execute, thus preventing the price from rising further. Even though the price cannot rise past this level, the reaction lows continue to rise. It is these higher lows that indicate increased buying pressure and give the ascending triangle its bullish bias.
Primus Telecom (PRTL) formed an ascending triangle over a 6-month period before breaking resistance with an expansion of volume.
The descending triangle is a bearish formation that usually forms during a downtrend as a continuation pattern. There are instances when descending triangles form as reversal patterns at the end of an uptrend, but they are typically continuation patterns. Regardless of where they form, descending triangles are bearish patterns that indicate distribution.
Because of its shape, the pattern can also be referred to as a right-angle triangle. Two or more comparable lows form a horizontal line at the bottom. Two or more declining peaks form a descending trend line above that converges with the horizontal line as it descends. If both lines were extended right, the descending trend line could act as the hypotenuse of a right triangle. If a perpendicular line were drawn extending up from the left end of the horizontal line, a right triangle would form. Let's examine each individual part of the pattern and then look at an example.
In contrast to the symmetrical triangle, a descending triangle has a definite bearish bias before the actual break. The symmetrical triangle is a neutral formation that relies on the impending breakout to dictate the direction of the next move. For the descending triangle, the horizontal line represents demand that prevents the security from declining past a certain level. It is as if a large buy order has been placed at this level and it is taking a number of weeks or months to execute, thus preventing the price from declining further. Even though the price does not decline past this level, the reaction highs continue to decline. It is these lower highs that indicate increased selling pressure and give the descending triangle its bearish bias.
After recording a lower high just below 60 in Dec-99, Nucor formed a descending triangle early in 2000. In late April, the stock broke support with a gap down, sharp break and increase in volume to complete the formation.
A Rectangle is a continuation pattern that forms as a trading range during a pause in the trend. The pattern is easily identifiable by two comparable highs and two comparable lows. The highs and lows can be connected to form two parallel lines that make up the top and bottom of a rectangle. Rectangles are sometimes referred to as trading ranges, consolidation zones or congestion areas.
There are many similarities between the rectangle and the symmetrical triangle. While both are usually continuation patterns, they can also mark trend significant tops and bottoms. As with the symmetrical triangle, the rectangle pattern is not complete until a breakout has occurred. Sometimes clues can be found, but the direction of the breakout is usually not determinable beforehand. We will examine each part of the rectangle and then provide an example with MU.
Rectangles represent a trading range that pits the bulls against the bears. As the price nears support, buyers step in and push the price higher. As the price nears resistance, bears take over and force the price lower. Nimble traders sometimes play these bounces by buying near support and selling near resistance. One group (bulls or bears) will exhaust itself and a winner will emerge when there is a breakout. Again, it is important to remember that rectangles have a neutral bias. Even though clues can sometimes be gleaned from volume patterns, the actual price action depicts a market in conflict. Only until the price breaks above resistance or below support will it be clear which group has won the battle.
In the summer of 1999, Micron Electronics (MU) advanced from the high teens to the low forties. After meeting resistance around 42, the stock settled in a trading range between 40 and 30 to form a rectangle.
A price channel is a continuation pattern that slopes up or down and is bound by an upper and lower trend line. The upper trend line marks resistance and the lower trend line marks support. Price channels with negative slopes (down) are considered bearish and those with positive slopes (up) bullish. For explanatory purposes, a “bullish price channel” will refer to a channel with positive slope and a “bearish price channel” to a channel with negative slope.
In a bullish price channel, some traders look to buy when prices reach main trend line support. Conversely, some traders look to sell (or short) when prices reach main trend line resistance in a bearish price channel. As with most price patterns, other aspects of technical analysis should be used to confirm signals.
Because technical analysis is just as much art as it is science, there is room for flexibility. Even though exact trend line touches are ideal, it is up to each individual to judge the relevance and placement of both the main trend line and the channel line. By that same token, a channel line that is exactly parallel to the main trend line is ideal.
CSCO provides an example of an 11-month bullish price channel that developed in 1999.
A price channel is a continuation pattern that slopes up or down and is bound by an upper and lower trend line. The upper trend line marks resistance and the lower trend line marks support. Price channels with negative slopes (down) are considered bearish and those with positive slopes (up) bullish. For explanatory purposes, a “bullish price channel” will refer to a channel with positive slope and a “bearish price channel” to a channel with negative slope.
In a bullish price channel, some traders look to buy when prices reach main trend line support.

The Measured Move is a three-part formation that begins as a reversal pattern and resumes as acontinuation pattern. The Bearish Measured Move consists of a reversal decline, consolidation/retracement and continuation decline. Because the Bearish Measured Move cannot be confirmed until after the consolidation/retracement period, it is categorized as a continuation pattern. The pattern is usually long-term and forms over several months.
More than one pattern can exist within the context of a Bearish Measured Move. A double top could mark the first reversal and decline, a price channel could form during this decline, a descending triangle could mark the consolidation and another price channel could form during the continuation decline.
During multi-year bear markets (or bull markets), a series of Bearish Measured Moves can form. A bear move consisting of three down legs might include a reversal and decline for the first leg, a retracement, a decline for the second leg, a retracement and finally the third leg decline.
While the projection targets for the continuation decline can be helpful, they should only be used as rough guidelines. Securities can overshoot their targets, but also fall short. Technical assessments should be ongoing.
As illustrated in the XIRCOM (XIRC) chart above, the second decline of a Bearish Measured Move may not be as orderly as the first, especially when volatile stocks are involved.
The Cup with Handle is a bullish continuation pattern that marks a consolidation period followed by a breakout. It was developed by William O'Neil and introduced in his 1988 book, How to Make Money in Stocks.
As its name implies, there are two parts to the pattern: the cup and the handle. The cup forms after an advance and looks like a bowl or rounding bottom. As the cup is completed, a trading range develops on the right hand side and the handle is formed. A subsequent breakout from the handle's trading range signals a continuation of the prior advance.
As with most chart patterns, it is more important to capture the essence of the pattern than the particulars. The cup is a bowl-shaped consolidation and the handle is a short pullback followed by a breakout with expanding volume. A cup retracement of 62% may not fit the pattern requirements, but a particular stock's pattern may still capture the essence of the Cup with Handle.
Any attempt to trace the origins of technical analysis would
inevitably lead to Dow Theory. While more than 100 years old, Dow theory remains the foundation of much of what we know today as technical analysis.
Dow theory was formulated from a series of Wall Street
Journal editorials authored by Charles H. Dow from 1900 until the time of his death in 1902. These editorials reflected Dow's beliefs on how the stock market behaved and how
the market could be used to measure the health of the business environment.
Due to his death, Dow never published his complete theory on the markets, but several followers and associates have published works that have expanded on the editorials. Some of
the most important contributions to Dow theory were William P. Hamilton's "The Stock Market Barometer" (1922), Robert Rhea's "The Dow Theory" (1932), E. George Schaefer's
"How I Helped More Than 10,000 Investors To Profit In Stocks" (1960) and Richard Russell's "The Dow Theory Today" (1961).
Dow believed that the stock market as a whole was a reliable measure of overall business conditions within the economy and that by analyzing the overall market, one could accurately gauge those
conditions and identify the direction of major market trends and the likely direction of individual stocks.
Dow first used his theory to create the Dow Jones Industrial Index and theDow Jones Rail Index (now Transportation Index), which were originally compiled
by Dow for The Wall Street Journal. Dow created these indexes because he felt they were an accurate reflection of the business conditions within the
economy because they covered two major economic segments: industrial and rail (transportation). While these indexes have changed over the last 100 years, the theory still applies to current
market indexes.
Much of what we know today as technical analysis has its roots in Dow's work. For this reason, all traders using technical analysis should get to know the six basic tenets
of Dow theory. Let's explore them.
The first basic premise of Dow theory suggests that all
information - past, current and even future - is discounted into the markets and reflected in the prices of stocks and indexes.
That information includes everything from the emotions of investors
to inflation and interest-rate data, along with pending earnings announcements to be made by companies after the close. Based on this tenet, the only information excluded is that
which is unknowable, such as a massive earthquake. But even then the risks of such an event are priced into the market.
It's important to note that this is not to suggest that market participants, or even the market itself, are all knowing, with the ability to predict future events. Rather, it means that over any
period of time, all factors - those that have happened, are expected to happen and could happen - are priced into the market. As things change, such as market risks, the market adjusts along with the
prices, reflecting that new information.
The idea that the market discounts everything is not new to technical traders, as this is a major premise of many of the tools used in this field of study. Accordingly, in technical analysis one need
only look at price movements, and not at other factors such as the balance sheet. (For more on this, see The Basics Of Technical Analysis.)
Like mainstream technical analysis, Dow theory is mainly focused on price. However, the two differ in thatDow theory is concerned with the movements of the broad markets,
rather than specific securities.
For example, a follower of Dow theory will look at the price movement of the major market indexes. Once they have an idea of the prevailing trend in the market, they will make an
investment decision. If the prevailing trend is upward, it follows that an investor would buy individual stocks trading at a fair valuation. This is where a broad understanding of
the fundamental factors that affect a company can be helpful.
It's important to note that while Dow theory itself is focused on price movements and index trends, implementation can also incorporate elements of fundamental analysis, including
value- and fundamental-oriented strategies.

An important part of Dow theory is distinguishing the overall direction of the market. To do this, the theoryuses trend analysis.
Before we can get into the specifics of Dow theory trend
analysis, we need to understand trends. First, it's important to note that while the market tends to move in a general direction, or trend, it doesn't do so in a straight line. The market will rally
up to a high (peak) and then sell off to a low (trough), but will generally move in one direction. (For related reading, see Peak-and-Trough Analysis.)

Figure 1: an uptrend |
An upward
trend is broken up into several rallies, where each rally has a high and a low. For a market to be considered in an uptrend, each
peak in the rally must reach a higher level than the previous rally's peak, and each low in the rally must be higher than the previous rally's low.
A downward
trend is broken up into several sell-offs, in which each sell-off also has a high and a low. To be considered a downtrend in Dow terms, each new low in the sell-off must be
lower than the previous sell-off's low and the peak in the sell-off must be lower then the peak in the previous sell-off.

Since the most vital trend to understand is the primary trend, this leads into the third tenet of Dow theory, which states that there are three phases to every primary trend – the
accumulation phase (distribution phase), the public participation phase and a panic phase (excess phase).
Let us now take a look at each of the three phases as they apply to both
bull and bear markets.
Primary Upward Trend (Bull Market)
The Accumulation Phase
The first stage of a bull market is referred to as the accumulation phase, which is the start of the upward trend. This is also considered the point at which informed investors start to enter the
market.
The accumulation phase typically comes at the end of a downtrend, when everything is seemingly at its worst. But this is also the time when the price of the market is at its most attractive level
because by this point most of the bad news is priced into the market, thereby limiting downside risk and offering attractive valuations.
However, the accumulation phase can be the most difficult one to spot because it comes at the end of a downward move, which could be nothing more than a secondary move in a primary downward trend -
instead of being the start of a new uptrend. This phase will also be characterized by persistent market pessimism, with many investors thinking things will only get worse.
From a more technical standpoint, the start of the accumulation phase will be marked by a period of price consolidation in the market. This occurs when the downtrend starts to flatten
out, as selling pressure starts to dissipate. The mid-to-latter stages of the accumulation phase will see the price of the market start to move higher. (For related reading,
see Consolidation - Trade The Calm, Profit From The Storm.)

Figure 1: the accumulation phase |
A new
upward trend will be confirmed when the market doesn't move to a consecutively lower low and high.
Public
Participation Phase
When
informed investors entered the market during the accumulation phase, they did so with the assumption that the worst was over and a recovery lay ahead. As this starts to materialize, the new primary
trend moves into what is known as the public participation phase.
During this phase, negative sentiment starts to dissipate as business
conditions - marked by earnings growth and strong economic data - improve. As the good news starts to permeate the market, more and more investors move back in, sending prices higher.
This phase tends not only to be the longest lasting, but also the one with the largest price movement. It's also the phase in which most technical and trend traders start to take long positions, as
the new upward primary trend has confirmed itself - a sign these participants have waited for.
Figure 2: the public participation phase |
The
Excess Phase
As the market has made a strong move higher on the improved business conditions and buying by market participants to move starts to age, we begin to move into the excess phase. At this point,
the market is hot again for all investors.
The last stage in the upward trend, the excess phase, is the one in which the smart money starts to scale back its positions, selling them off to those now entering the market. At this point, the
market is marked by, as Alan Greenspan might say, "irrational exuberance". The perception is that everything is running great and that only good things lie ahead. (For more insight,
read How Investors Often Cause The Market's Problems and The Madness Of Crowds.)
This is also usually the time when the last of the buyers start to enter the market - after large gains have been achieved. Like lambs to the slaughter, the late entrants hope that recent returns
will continue. Unfortunately for them, they are buying near the top.
During this phase, a lot of attention should be placed on signs of weakness in the trend, such as strengthening downward moves. Also, if the upward moves start to show weakness, it could be another
sign that the trend may be near the start of a primary downtrend.

Primary Downward Trend (Bear Market)
The Distribution Phase
The first phase in a bear market is known as the distribution phase, the period in which informed buyers sell (distribute) their positions. This is the opposite of the accumulation phase during a
bull market in that the informed buyers are now selling into an overbought market instead of buying in an oversold market.
In this phase, overall sentiment continues to be optimistic, with expectations of higher market levels. It is also the phase in which there is continued buying by the last of the investors in the
market, especially those who missed the big move but are hoping for a similar one in the near future.
As was the case in the accumulation phase, the distribution phase can be difficult to spot in its early stages. The reason for this is that it may be disguised as a secondary downward trend within
the primary upward trend.
From a technical standpoint, the distribution phase is represented by a topping of the market where the price movement starts to flatten as selling pressure increases . The mid to latter
stages of the distribution phase will see prices start to fall as more and more investors, anticipating weakness, exit their positions.
A new downward trend will be confirmed when the previous trend fails to make another consecutive higher high and low.
Public Participation Phase
This phase is similar to the public participation phase found in a primary upward trend in that it lasts the longest and will represent the largest part of the move - in this case
downward.
During this phase it is clear that the business conditions in the market are getting worse and the sentiment is becoming more negative as time goes on. The market continues to discount the worsening
conditions as selling increases and buying dries up.
This is also the point at which most trend followers and technical traders start to dump their positions and take short positions as the new downward trend has confirmed itself.
The Panic Phase
The last phase of the primary downward market tends to be filled with market panic and can lead to very large sell-offs in a very short period of time. In the panic phase, the market is wrought up
with negative sentiment, including weak outlooks on companies, the economy and the overall market.
During this phase you will see many investors selling off their stakes in panic. Usually these participants are the ones that just entered the market during the excess phase of the previous
run-up in share price.
But
just when things start to look their worst is when the accumulation phase of a primary upward trend will begin and the cycle repeats itself. (For related articles,

Under Dow theory, a major reversal from a bull to a bear market (or vice versa) cannot be signaled unless both indexes (traditionally the Dow Industrial and Rail
Averages) are in agreement.
For example, if one index is confirming a new primary uptrend but another index remains in a primary downward trend, it is difficult to assume that a new trend has begun.
The reason for this is that a primary trend, either up or down, is the
overall direction of the stock market, which in Dow theory is a reflection of business conditions in the economy. When the stock market is doing well, it is because business conditions
are good; when the stock market is doing poorly, it is due to poor business conditions. If the two Dow indexes are in conflict, there is no clear trend in business conditions. (For related
reading, see Forces That Move Stock Prices.)
If business conditions cause the major indexes to travel in opposite directions, this disparity suggests that it will be difficult for a primary trend to develop. When trying to confirm a new primary
trend, therefore, it's vital that more than one index shows similar signals within a relatively close period of time. If the indexes are in agreement, it is a sign that business conditions are moving
in the indicated direction. Thus, rising indexes signal a new uptrend.
By Chad Langager and Casey
Murphy, senior analyst of ChartAdvisor.com
According to Dow theory, the main signals for buying and selling are based on the price movements of the indexes. Volume is also used as a secondary indicator to help confirm what
the price movement is suggesting. (For more insight, see Volume Oscillator Confirms Price Movements and Gauging Support And Resistance With Price By
Volume.)
From this tenet it follows that volume should increase when the price
moves in the direction of the trend and decrease when the price moves in the opposite direction of the trend. For example, in an uptrend, volume should increase when the price rises and fall when the
price falls. The reason for this is that the uptrend shows strength when volume increases because traders are more willing to buy an asset in the belief that the upward momentum will continue. Low
volume during the corrective periods signals that most traders are not willing to close their positions because they believe the momentum of the primary trend will continue.
Conversely, if volume runs counter to the trend, it is a sign of weakness in the existing trend. For example, if the market is in an uptrend but volume is weak on the up move, it is a signal that
buying is starting to dissipate. If buyers start to leave the market or turn into sellers, there is little chance that the market will continue its upward trend. The same is true for increased volume
on down days, which is an indication that more and more participants are becoming sellers in the market.
According to Dow theory, once a trend has been confirmed by volume, the majority of money in the market should be moving with the trend and not against it.
By Chad Langager and Casey
Murphy, senior analyst of ChartAdvisor.com
The reason for identifying a trend is to determine the overall direction of the market so that trades can be made with the trends and not against them. As was illustrated in the third tenet, trends move from uptrend to downtrend, which makes it important to identify transitions between these two trend directions. (For related reading, see Track Stock Prices With Trendlines.)
In Dow theory, the sixth and final tenet states that a trend
remains in effect until the weight of evidence suggests that it has been reversed.
Traders wait for a clear picture of a trend reversal because the goal is not to confuse a true reversal in the primary trend with a secondary trend or brief correction. Remember that a secondary
trend is a move in the opposite direction of the primary trend that will not continue. For example, imagine that the primary trend is up, but the indexes are currently selling off. If an investor
were to take a short position, concluding that the sell-off is the start of a new primary downward trend, they could get burned when the primary trend continues.
Unless you can safely conclude, based on the weight of evidence, that the trend has changed, you will be trading against the trend. As a general rule, this is not a wise idea, as many have been hurt
by trading against the market.
So far, we have discussed a lot of the ideas behind Dow theory along with its main tenets. In this section, we'll take a look at the technical approach behind Dow theory,
such as how to identify trend reversals.
Closing Prices and LineRanges
Charles Dow relied solely on closing prices and was not concerned about the intraday movements of the index. For a trend signal to be formed, the closing price has to signal the trend, not
an intraday price movement.
Another feature in Dow theory is the idea of line ranges, also referred to as trading ranges in other areas of technical analysis. These periods of sideways (or horizontal) price
movements are seen as a period of consolidation, and traders should wait for the price movement to break the trend line before coming to a conclusion on which way the market is headed. For
example, if the price were to move above the line, it's likely that the market will trend up.
Signals and Identification of Trends
One difficult aspect of implementing Dow theory is the accurate identification of trend reversals. Remember, a follower of Dow theory trades with the overall direction
of the market, so it is vital that he or she identifies the points at which this direction shifts. (For related reading, see Retracement Or Reversal: Know The Difference.)
One of the main techniques used to identify trend reversals
in Dow theory is peak-and-trough analysis. A peak is defined as the highest price of a market movement, while a trough is seen as lowest price of a market movement.
Note that Dow theory assumes that the market doesn't move in a straight line but from highs (peaks) to lows (troughs), with the overall moves of the market trending in a direction.
(For more on this topic, read Peak-And-Trough Analysis and The Ups And Downs Of Investing In Cyclical Stocks.)
An upward trend in Dow theory is a series of successively higher peaks and higher troughs.
There is little doubt that Dow theory is of major importance in the history of technical analysis. Many of its tenets and ideas are the basis of much of what we know today. Aspects
of Dow theory are also incorporated into other theories, such as Elliott Wave theory. (To learn about this concept, see Elliott
WaveTheory and Elliott Wave In The 21st Century.)
However, since its original adaptation and subsequent updates, its
relevance as a stand-alone analytical technique has weakened. The reason for this has been the advent of more advanced techniques and tools, which in part build off of Dow theory, but
greatly expand upon it.
One of the bigger problems with the theory is that followers can miss out on large gains due to the conservative nature of a trend-reversal signal. As we mentioned previously, a signal is
confirmed when there is an end to successive highs (uptrend) or lows (downtrend). However, what often happens is that by the time the market has shown a clear sign of reversal, the market has already
generated a large gain.
Another problem with Dow theory is that over time, the economy - and the indexes originally used by Dow - has changed. Consequently, the link between them has weakened. For
example, the industrial and transportation sectors of the economy are no longer the dominant parts. Technology, for example, now takes up a considerable portion of economic production and
growth.
This is important because the basis for watching the indexes is that they are the leading indicators of business conditions. The economy has clearly become more segmented, requiring
the analysis of more indexes, which could greatly reduce the accuracy and timeliness of Dow theory analysis. Imagine having to look at six indexes while still adhering to Tenet #4:
Indexes Must Confirm Each Other.
Even though there are weaknesses in Dow theory, it will always be important to technical analysis.
The ideas of trending markets and peak-and-trough analysis are found constantly within technical writings and ideas. Also of importance in Dow theory is the idea of emotions in the
marketplace, which remains a characteristic of market trends.
Charles Dow and Dow theory helped investors improve their understanding of the markets so that they could maker better investments and achieve investment success.
Dow theory represents the beginning of technical analysis.
Understanding this theory should lead you to a better understanding of technical analysis and of an analyst's view of how markets work.
Let's recap what we've learned:
Ralph Nelson Elliott developed the Elliott Wave Theory in the late 1920s by discovering that stock markets, thought to behave in a somewhat chaotic manner, in fact traded in repetitive cycles.
Elliott discovered that these market cycles resulted from investors' reactions to outside influences, or predominant psychology of the masses at the time. He found that the upward and downward swings of the mass psychology always showed up in the same repetitive patterns, which were then divided further into patterns he termed "waves".
Elliott's theory is somewhat based on the Dow theory in that stock prices move in waves. Because of the "fractal" nature of markets, however, Elliott was able to break down and analyze them in much greater detail. Fractals are mathematical structures, which on an ever-smaller scale infinitely repeat themselves. Elliott discovered stock-trading patterns were structured in the same way.
Market Predictions Based
on Wave Patterns
Elliott made detailed stock market predictions based on unique characteristics he discovered in the wave patterns. An impulsive wave, which goes with the main trend,
always shows five waves in its pattern. On a smaller scale, within each of the impulsivewaves, five waves can again be found. In this smaller pattern, the same pattern repeats
itself ad infinitum. These ever-smaller patterns are labeled as different wave degrees in the Elliott Wave Principle. Only much later were fractals recognized by
scientists.
In the financial markets we know that "every action creates an equal and opposite reaction" as a price movement up or down must be followed by a contrary movement. Price action is divided into trends and corrections or sideways movements. Trends show the main direction of prices while corrections move against the trend. Elliott labeled these "impulsive" and "corrective" waves.
Theory
Interpretation
The Elliott Wave Theory is interpreted as follows:
Let's have a look at the following chart made up of eight waves (five up and three down) labeled 1, 2, 3, 4, 5, A, B and C.
![]() |
You can see that the three waves in the direction of the trend are impulses, so these waves also have five waves within them. The waves against the trend are corrections and are composed of three waves.

Theory Gained Popularity in
the 1970s
In the 1970s, this wave principle gained popularity through the work of Frost and Prechter. They published a legendary book on the Elliott Wave entitled
"The Elliott Wave Principle – The Key to Stock Market Profits". In this book, the authors predicted the bull market of the 1970s, and Robert Prechter called
the crash of 1987. (For related reading, see Digging Deeper Into Bull And Bear Markets and The Greatest Market Crashes.)

The corrective wave formation normally has three distinct price movements - two in the direction of the main correction (A and C) and one against it (B). Waves 2 and 4 in the above picture are corrections. These waves have the following structure:
![]() |
Note that waves A and C move in the direction of the shorter-term trend, and therefore are impulsive and composed of five waves, which are shown in the picture above.
An impulse-wave formation, followed by a corrective wave, form an Elliott wave degree consisting of trends and countertrends. Although the patterns pictured above are bullish, the same applies for bear markets where the main trend is down.
Series
of Wave Categories
The Elliott Wave Theory assigns a series of categories to the waves from largest to smallest. They are:
To use the theory in everyday trading, the trader determines the main wave, or supercycle, goes long and then sells or shorts the position as the pattern runs out of steam and a reversal is imminent.
