ZigZag指标

这个指标可以显示当前货币对当前周期的波浪，在事后配合波浪理论研究时很有用，但是实盘时是很后置的，画出的线会根据当前的最高点和最低点即时调整。
这个指标在实盘中虽然用处不大，但是可以配合其他指标来交易，另外还有一个用途就是当它画出最高点或者最低点时炒短线的用户可以根据情况平仓，适合比较谨慎的交易者。
以下是ZigZag指标的英文描述：

ZigZag
The Zigzag indicator is a series of trend lines connecting significant peaks and foundations at the price plot. Minimum price change parameter determines the percentage for the price to move in order to form a new "Zig" or "Zag" line. This indicator eliminates those changes on the plot we analyze that are less than the given v alue. Therefore, the Zigzag reflects significant changes only.
In most cases, we use Zigzag to facilitate the perception of plots as it shows only the most important changes and turns. You can also reveal Elliot Waves and various figures on the plot with its aid.

It is important to understand that the last section of the indicator may vary depending on the changes of data you analyze. This is one of those indicators, where a change of securities price can provoke a change of the previous value. This ability to correct its values by the following price changes makes Zigzag a perfect tool for analyzing price changes that have already happened. Therefore, you should not try to create a trade system basing on the Zigzag. It is more suitable for analyzing historical data than for making prognoses.
