The ZigZag feature on SharpCharts is not an indicator per se, but rather a means to filter out smaller price movements. A ZigZag set at 10% would ignore all price movements less than 10%. Only price movements greater than 10% would be shown. Filtering out smaller movements gives chartists the ability to see the forest instead of just trees. It is important to remember that the ZigZag feature has no predictive power because it draws lines base on hindsight. Any predictive power will come from applications such as Elliott Wave, price pattern analysis or indicators. Chartists can also use the ZigZag with retracements feature to identify Fibonacci retracements and projections.
Calculation
The ZigZag is based on the chart “type.” Line and dot charts, which are based on the close, will show the ZigZag based on closing prices. High-Low-Close bars (HLC), Open-High-Low-Close (OHLC) bars and candlesticks, which show the period's high-low range, will show the ZigZag based on this high-low range. A ZigZag based on the high-low range is more likely to change course than a ZigZag based on the close because the high-low range will be much larger and produce bigger swings.
The parameters box allows chartists to set the sensitivity of the ZigZag feature. A ZigZag with 5 in the parameter box will filter out all movements less than 5%. A ZigZag(10) will filter out movements less than 10%. If a stock traded from a reaction low of 100 to a high of 109 (+9%), there would not be a line because the move was less than 10%. If the stock advanced from a low of 100 to a high of 110 (+10%), there would be a line from 100 to 110. If the stock continued on to 112, this line would extend to 112 (100 to 112). The ZigZag would not reverse until the stock declined 10% or more from its high. From a high of 112, a stock would have to decline 11.2 points (or to a low of 100.8) to warrant another line. The chart below shows a QQQQ line chart with a 7% ZigZag. The early June bounce was ignored because it was less than 7% (black arrow). The two pullbacks in July were ignored because they were much less than 7% (red arrows).
Be careful with the last ZigZag line. Astute chartists will notice that the last ZigZag line is up even though QQQQ advanced just 4.13% (43.36 to 45.15). This is just a temporary line because QQQQ has yet to reach the 7% change threshold. A move to 46.40 is needed for a gain of 7%, which would then warrant a permanent ZigZag line. Should QQQQ fail to reach the 7% threshold on this bounce and then decline below 43, this temporary line would disappear and the prior ZigZag line would continue from the early August high.
Elliott Wave Counts
The ZigZag feature can be used to filter out small moves and make Elliott Wave counts more straight-forward. The chart below shows the S&P 500 ETF with a 6% ZigZag to filter moves less than 6%. After a little trial and error, 6% was deemed the threshold of importance. An advance or decline greater than 6% was deemed significant enough to warrant a wave for an Elliott count. Keep in mind that this is just an example. The threshold and the wave count are subjective and dependent on individual preferences. Based on the 6% ZigZag, a complete cycle was identified from March 2009 until July 2010. A complete cycle consists of 8 waves, 5 up and 3 down.
Retracements and Projections
Sharpcharts users can choose between the normal “ZigZag” and “ZigZag (Retrace.).” As shown in the examples above, the normal ZigZag shows lines that move at least a specific percentage. The ZigZag (Retrace.) connects the reaction highs and lows with labels that measure the prior move. The numbers on the dotted lines reflect the difference between the current Zigzag line and the ZigZag line immediately before it. For example, the chart below shows Altera (ALTR) with the 15% ZigZag (Retrace.) feature. Three ZigZag lines have been labeled (1, 2 and 3). The dotted line connecting the low of Line 1 with the low of Line 2 shows a box with 0.638. This means Line 2 is .638 (63.8%) of Line 1. A number below 1 means the line is shorter than the prior line. The dotted line connecting the high of Line 2 with the high of Line 3 shows a box with 1.646. This means Line 3 is 1.646 (164.6%) of Line 2. A number above 1 means the line is longer than the prior line.
As you may have guessed, seeing these lines as a percentage of the prior lines makes it possible to assessFibonacci retracements Fibonacci projections. The August decline (Line 2) retraced around 61.8% of the June-July advance (Line 1). This is a classic Fibonacci retracement. The advance from early September to early November was 1.646 times the August decline. In this sense, the ZigZag (Retrace.) can be used to project the length of an advance. Again, 1.646 is close to the Fibonacci 1.618, which is the Golden Ratio used in many projection estimates. See our ChartSchool article for more on Fibonacci retracements.
Conclusions
The ZigZag and ZigZag (Retrace.) filter price action and do not have any predictive power. The ZigZag lines simply react when prices move a certain percentage. Chartists can apply an array of technical analysis tools to the ZigZag. Chartists can perform basic trend analysis by comparing reaction highs and lows. Chartists can also overlay the ZigZag feature to look for price patterns that might not be as visible on a normal bar or line chart. The ZigZag has a way of highlighting the important movements and ignoring the noise. When using the ZigZag feature, don't forget to measure the last line to determine if it is temporary or permanent. The last ZigZag line is temporary if the current price change is less than the ZigZag parameter. The last line is permanent when the price change is greater than or equal to the ZigZag parameter.
SharpCharts
The ZigZag and ZigZag (Retrace.) can be found in SharpCharts as a price overlay in the Chart Attributes section or as an addition to an indicator. Upon selecting the Zigzag feature from the drop down box, the parameters window will appear empty. Five (5%) is the default parameter, but this can change depending on a security's price characteristics. Some securities produce too few Zigzag lines at 5% so the default is set lower (e.g. 3.75%). Some securities produce too many zigzag lines at 5% so the default is set higher (e.g. 6.25%). The Zigzag parameter can be seen in the upper left corner of the chart. Once the Zigzag feature is applied, chartists can adjust the parameter to suit their charting needs. A lower number will make the feature more sensitive, while a higher number will make it less sensitive. Click here for a live chart with the Zigzag (Retrace.) feature.

Many people believe that the markets are random. In fact, one of the most prominent investing books out there is "A Random Walk Down Wall Street" (1973) by Burton G. Malkiel, who argues that throwing darts at a dartboard is likely to yield results similar to those achieved by a fund manager (and Malkiel does have many valid points).
However, many others argue that although prices may appear to be random, they do in fact follow a pattern in the form of trends. One of the most basic ways in which traders can determine such trends is through the use of fractals. Fractals essentially break down larger trends into extremely simple and predictable reversal patterns. This article will explain what fractals are and how you might apply them to your trading to enhance your profits.
What Are Fractals? When many people think of fractals in the mathematical sense, they think of chaos theory and abstract mathematics. While these concepts do apply to the market (it being a nonlinear, dynamic system), most traders refer to fractals in a more literal sense. That is, as recurring patterns that can predict reversals among larger, more chaotic price movements.
These basic fractals are composed of five or more bars. The rules for identifying fractals are as follows:
ADVERTISING
A bearish turning point occurs when there is a pattern with the highest high in the middle and two lower highs on each side.
A bullish turning point occurs when there is a pattern with the lowest low in the middle and two higher lows on each side.
The fractals shown in Figure 1 are two examples of perfect patterns. Note that many other less perfect patterns can occur, but the basic pattern should remain intact for the fractal to be valid.
Figure 1
The obvious drawback here is that fractals are lagging indicators - that is, a fractal can't be drawn until we are two days into the reversal. While this may be true, most significant reversals last many more bars, so most of the trend will remain intact (as we will see in the example below).
Applying Fractals to Trading Like many trading indicators, fractals are best used in conjunction with other indicators or forms of analysis. Perhaps the most common confirmation indicator used with fractals is the "Alligator indicator", a tool that is created by using moving averages that factor in the use of fractal geometry. The standard rule states that all buy rules are only valid if below the "alligator's teeth" (the center average), and all sell rules are only valid if above the alligator's teeth.
Figure 2 is an example of such a setup:
Figure 2
As you can see, the primary drawback to this system is the large swings that take place. Notice, for example, that the latest fractal had a drawdown of over 100 pips and still has not hit an exit point. However, there are countless other techniques that can be applied in conjunction with fractals to produce profitable trading systems.
Figure 3 shows a forex trading setup that uses a combination of fractals (multiple time frames), Fibonacci-based moving averages (placed at 89, 144, 233, 377 and their inverses) and a momentum indicator. Let's look at a recent trade setup for the GBP/USD currency pair to see how fractals can help:
Figure 3
Here is a basic rule setup that is used when using a chart with a four-hour time frame:
Initiate a position when the price has hit the farthest Fibonacci band, but only after a daily (D1) fractal takes place.
Exit a position after a daily (D1) fractal reversal takes place.
Notice how the fractals pinpoint meaningful tops and bottoms? This helps to take the guesswork out of deciding at which Fibonacci level to trade - all we have to do is check to see if the daily fractal occurred. We should also note that the trend strength began increasing at the sell fractal, and topped at the buy fractal. Although we lose some pips with the confirmation, it saves us from losing out on mere market noise - 139 pips certainly isn't bad for three days! (For further reading, see Trading Without Noise.)
Things to Consider Here are a few things to remember when using fractals:
They are lagging indicators. They are best used as confirmation indicators to help confirm that a reversal did take place. Real-time tops and bottoms can be surmised with other techniques.
The longer the time period (i.e. the number of bars required for a fractal), the more reliable the reversal. However, you should also remember that the longer the time period, the lower the number of signals generated.
It is best to plot fractals in multiple time frames and use them in conjunction with one another. For example, only trade short-term fractals in the direction of the long-term ones. Along these same lines, long-term fractals are more reliable than short-term fractals.
Always use fractals in conjunction with other indicators or systems. They work best as decision support tools, not as indicators on their own.
Conclusion As you can see, fractals can be extremely powerful tools when used in conjunction with other indicators and techniques, especially when used to confirm reversals. The most common usage is with the "Alligator indicator"; however, there are other uses too, as we've seen here. Overall, fractals make excellent decision support tools for any trading method.

In the world of short-term trading, experiences are defined by a trader's ability to anticipate a certain move in the price of a financial asset. There are many different indicators used to predict an asset's future direction, but few have proved to be as useful and easy to interpret as the parabolic SAR. In this article, we'll take a look at the basics of this indicator and show you how you can incorporate it into your trading strategy.
The Indicator
The parabolic SAR is a technical indicator that is used by many traders to determine the direction of an asset's momentum and the point in time when this momentum has a higher-than-normal probability of switching directions. Sometimes known as the "stop and reversal system", the parabolic SAR was developed by the famous technician Welles Wilder, creator of the relative strength index, and it is shown as a series of dots placed either above or below an asset's price on a chart.
One of the most important aspects to keep in mind is that the positioning of the "dots" is used by traders to generate transaction signals depending on where the dot is placed relative to the asset's price. A dot placed below the price is deemed to be a bullish signal, causing traders to expect the momentum to remain in the upward direction. Conversely, a dot placed above the prices is used to illustrate that the bears are in control and that the momentum is likely to remain downward. (For further reading, see How is the parabolic SAR used in trading?)
ADVERTISING
The first entry point on the buy side occurs when the most recent high price of an issue has been broken; it is at this time that the SAR is placed at the most recent low price. As the price of the stock rises, the dots will rise as well, first slowly and then picking up speed and accelerating with the trend. This accelerating system allows the investor to watch the trend develop and establish itself. The SAR starts to move a little faster as the trend develops and the dots soon catch up to the price action of the issue. As you can see in Figure 1, the indicator works extremely well when a stock is trending, but it can lead to many false signals when the price moves sideways or is trading in a choppy market.
Parabolic SAR and the Short Sale
The parabolic SAR is extremely valuable because it is one of the easiest methods available for strategically setting the position of a stop-loss order. As you become more acquainted with technical indicators, you'll find that the parabolic SAR has built up quite the positive reputation for its role in helping many traders lock-in paper profits that have been realized in a trending environment. You can also see that professional traders whoshort the market will use this indicator to help determine the time to cover their short positions. (For more, see Trailing-Stop Techniques.)
It is important to note that this indicator is extremely mechanical and will always assume that the trader is holding a long or short position. The ability for the parabolic SAR to respond to changing conditions removes all human emotion and allows the trader to be disciplined. On the other hand, the disadvantage of using this indicator can also be seen in Figure 1. Notice how the signals can lead to many false entries during periods of consolidation. Being whipsawed in and out of trades can often be extremely frustrating, even for the most successful traders.
