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.
The ZigZag and 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.
