Analyzing Chart Patterns: Why Charts?
By Chad Langager and Casey Murphy, senior analyst of ChartAdvisor.com
Before the advent of computers and data feeds, the use of charts to formulate trading strategies was outside the mainstream of trading techniques. The reason, creating charts was difficult. Each chart had to be created by hand, with chartists adding another data point at the close of trading for each security they were following. Also, chart users were often misrepresented as a bizarre group of individuals huddled in the recesses of the brokerage house as they added the latest data point to their closely coveted charts.
But with the advancement of technology and the increased popularity of technical analysis, the use of charts has greatly increased, making them one of, if not the most important tools used by technical traders.
A single chart has the ability to display a significant amount of information. More conceptually, charts are an illustration of the struggle between buyers and sellers. While this point is debatable between the schools of investment like technical, fundamental and efficient market analysis, technical analysis assumes that: a) prices discount everything, b) prices moves in trends and c) history repeats itself.
Assuming the above tenets are true, charts can be used to formulate trading signals and can even be the only tool a trader utilizes.
Patterns on a Chart
Chart patterns signal to traders that the price of a security is likely to move in one direction or another when the pattern is complete.
There are two types of patterns in this area of technical analysis: reversal and continuation. A reversal pattern signals that a prior trend will reverse on completion of the pattern. Conversely, a continuation pattern indicates that the prior trend will continue onward upon the pattern's completion.
The difficulty in identifying chart patterns and their subsequent signals is that chart use is not an exact science. In fact, it's often viewed as more of an art than a science. While there is a general idea and components to every chart pattern, the price movement does not necessarily correspond to the pattern suggested by the chart. This should not discourage potential users of charts - once the basics of charting are understood, the quality of chart patterns can be enhanced by looking at volume and secondary indicators.
There are several concepts that need to be understood before reading about specific chart patterns. The first is a trendline, which is a line drawn on a chart to signal a level of support or resistance for the price of the security. Support trendlines are the levels at which prices have difficulty falling below. Conversely, a resistance trendline illustrates the level at which prices have a hard time going above. These trendlines can be constant price levels, such as $50, or rise or fall in the direction of the trend as time goes on.
Now that we have an understanding of the concepts behind the use of charts as a trading technique, we can start to explore the many different patterns used by chartists.
The Elliott Wave Principle
In the 1930s, Ralph Nelson Elliott, a corporate accountant by profession, studied price movements in the financial markets and observed that certain patterns repeat themselves. He offered proof of his discovery by making astonishingly accurate stock market forecasts. What appears random and unrelated, Elliott said, will actually trace out a recognizable pattern once you learn what to look for.
Elliott called his discovery "The Elliott Wave Principle," and its implications were huge. He had identified the common link that drives the trends in human affairs, from financial markets to fashion, from politics to popular culture. Robert Prechter, Jr., president of Elliott Wave International, resurrected the Wave Principle from near obscurity in 1976 when he discovered the complete body of R.N. Elliott's work in the New York Library. Robert Prechter, Jr. and A.J. Frost published Elliott Wave Principle in 1978. The book received enthusiastic reviews and became a Wall Street bestseller.
In Elliott Wave Principle, Prechter and Frost's forecast called for a roaring bull market in the 1980s, to be followed by a record bear market. Needless to say, knowledge of the Wave Principle among private and professional investors grew dramatically in the 1980s. When investors and traders first discover the Elliott Wave Principle, there are several reactions: • Disbelief – that markets are patterned and largely predictable by technical analysis alone • Joyous “irrational exuberance” – at having found a “crystal ball” to foretell the future • And finally the correct, and useful response – “Wow, here is a valuable new tool I should learn to use.” Just like any system or structure found in nature, the closer you look at wave patterns, the more structured complexity you see. It is structured, because nature’s patterns build on themselves, creating similar forms at progressively larger sizes.
You can see these fractal patterns in botany, geography, physiology, and the things humans create, like roads, residential subdivisions… and – as recent discoveries have confirmed – in market prices. Natural systems, including Elliott wave patterns in market charts, “grow” through time, and their forms are defined by interruptions to that growth. Here's what is meant by that. When your hands formed in the womb, they first looked like round paddles growing equally in all directions. Then, in the places between your fingers, cells ceased growing or died, and growth was directed to the five digits.
This structured progress and regress is essential to all forms of growth. That this “punctuated growth” appears in market data is only natural – as Robert Prechter, Jr., the world's foremost Elliott wave expert and president of Elliott Wave International, says, “Everything that thrives must have setbacks.”
The first step in Elliott wave analysis is identifying patterns in market prices. At their core, wave patterns are simple; there are only two of them: “impulse waves,” and “corrective waves.” Impulse waves are composed of five sub-waves and move in the same direction as the trend of the next larger size (labeled as 1, 2, 3, 4, 5). Impulse waves are called so because they powerfully impel the market. A corrective wave follows, composed of three sub-waves, and it moves against the trend of the next larger size (labeled as a, b, c). Corrective waves accomplish only a partial retracement, or "correction," of the progress achieved by any preceding impulse wave.
As the figure to the right shows, one complete Elliott wave consists of eight waves and two phases: five-wave impulse phase, whose sub-waves are denoted by numbers, and the three-wave corrective phase, whose sub-waves are denoted by letters. What R.N. Elliott set out to describe using the Elliott Wave Principle was how the market actually behaves. There are a number of specific variations on the underlying theme, which Elliott meticulously described and illustrated. He also noted the important fact that each pattern has identifiable requirements as well as tendencies. From these observations, he was able to formulate numerous rules and guidelines for proper wave identification. A thorough knowledge of such details is necessary to understand what the markets can do, and at least as important, what it does not do. You have only just begun to learn the power and complexity of the Elliott Wave Principle. So, don't let your Elliott wave education end here. Join Elliott Wave International's free Club EWI .

The Parabolic Trigger for V Tops and Bottoms
Our previous article about using the ADX for V shaped tops and bottoms was surprisingly well received. We had a great deal of very favorable feedback from our members who experimented with it. This very valuable pattern seems to do an excellent job of spotting major turning points in almost any market from Palladium to Natural Gas to Soybeans or even Lumber.
This pattern seems to work extremely well in almost all futures, stocks and even the hard to trade stock indexes. Much like a kid with a new toy, we've been having fun scanning through our charts and finding all the important signals that have been generated.
For example, when looking at the stock index charts we had some very timely and important signals that the strong bear market in stocks was finally reversing. Let's review very briefly the conditions that create the pattern we are looking for. REVIEW OF SETUPS and TRIGGERS: For those of you who are new to our work, we strongly recommend a two step process for entries. The first step is to identify some "setup" conditions that tell us that an entry is near.
The second step is the "trigger" that tells us we must enter the trade NOW. Just to refresh your memory from the previous Bulletin, let me review the "setup" conditions that we are looking for. Remember that we are trying to anticipate important "V" shaped reversal patterns. We want to be able to trade as near as possible to major tops and bottoms.
As most of you are aware, a major directional price move will cause the ADX to rise to a high level. Depending on the direction of the price movement, either the Plus DI or the Minus DI will also move to an unusually high level. As the market peaks the DI will begin to decline while the ADX is flat or still rising. Near the top (or bottom) the ADX will become the highest line and will be above both the Plus DI and the Minus DI lines.
This is our "setup" and alerts us that an important change in direction is likely in the very near future. The relationship of the three lines with the ADX being the highest tells us that there has already been a very extended price move that is running out of gas. FINDING A TIMELY TRIGGER: While studying the charts using our new ADX pattern we found that our setup conditions often occurred early and that our DMI triggers were sometimes a little bit late. We don't mind having the setup conditions occur early.
After all, lead indicators are rare and very hard to find. However to make this entry pattern even more exciting we thought we would see if we could make the triggers occur sooner. Now that we have our lead indicator in place we want to find a timely entry trigger that gets us started in the direction of the new trend that should just be getting started.
In Bulletin 45 we suggested that the crossing of the Plus DI and Minus DI lines could be the entry trigger. Although this method is acceptable and produces excellent results we observed that there might be room for further improvement. In many cases, by the time the Plus and Minus DI have crossed some profits in the new direction have already been left behind.
After some trial and error we found that the Parabolic indicator did just what we wanted. We believe we can use the Parabolic indicator instead of the DMI crossovers to provide much more timely entry triggers. We have never liked the Parabolic stop and reverse (SAR) method as an independent trading system which was the intent of J. Welles Wilder, its originator.
However we do like to use the Parabolic indicator for exits. As a system we find that the Parabolic reversal points occur much too frequently and this reversal system would drive us crazy with far too many false changes in direction. However the features of the Parabolic indicator that make it useful as an exit strategy are exactly what makes it the timely trigger we need for our ADX reversal pattern.
The Parabolic indicator accelerates steadily as the prices trend until the reversal points are very, very close to the peak of the move. The stronger the trend the closer the Parabolic gets to the prices. That is exactly what we want. When the Parabolic indicator is close to the prices and we have fulfilled our ADX setup conditions we are all set for an outstanding trade. Even a very small countertrend move will now quickly cross the Parabolic and signal our timely entry. AN IDEAL ENTRY PLUS AN ADD POINT: We view the marriage of the ADX setup with the Parabolic entry trigger as an ideal combination.
The entries now occur in a much more timely fashion than when we relied on the DI crossovers for our trigger. In fact, once the Parabolic has been crossed we can use the DI crossover as a confirmation and add to our position. I don't normally believe in pyramiding positions but in this case we are trading a very reliable pattern that is designed to identify a major reversal in direction, so I think that adding to positions early is a very good strategy. As you can probably tell, I really like this ADX and Parabolic entry technique and I think that we have a lot of good concepts working for us here. We have an early setup, a timely trigger and now we can use the delayed confirmation of the DI crossovers as a point to pyramid the position. You can't ask for much more than that for an entry strategy that does a great job of catching big moves early. Take a look at this pattern on your favorite market and give me your comments. Good luck and good trading. by Chuck LeBeau
