官方ZIGZAG指标在程序调用时会出现与加载图表时值不符的情况，下面的指标源码能很好地解决这个问题
里面含有几个源码：这是其中一段
//---- author of the indicator
#property copyright "Copyright ?2005, MetaQuotes Software Corp."
//---- link to the website of the author
#property link "http://www.metaquotes.net/"
//---- indicator version
#property version "1.00"
#property description "ZigZag"
//+----------------------------------------------+
//| Indicator drawing parameters |
//+----------------------------------------------+
//---- drawing the indicator in the main window
#property indicator_chart_window
//---- 2 buffers are used for calculation of drawing of the indicator
#property indicator_buffers 2
//---- only 1 plot is used
#property indicator_plots 1
//---- ZIGZAG is used for the indicator
#property indicator_type1 DRAW_ZIGZAG
//---- displaying the indicator label
#property indicator_label1 "ZigZag_NK"
//---- use blue violet color for the indicator line
#property indicator_color1 BlueViolet
//---- the indicator line is a long dashed line
#property indicator_style1 STYLE_DASH
//---- indicator line width is equal to 1
