请教如何在指标中编写,在两线之间画线段

wangjia

各位老师,思路如下:1.当两线之间距离由大变小时,在K棒对应的两指标线之间画线段;2.当两线之间距离由小变大时,在K棒对应的两指标线之间画线段;我的指标代码如下:#property indicator_chart_window#property indicator_buffers 5#property indicator_color1 White#property indicator_color2 Yellow#property indicator_color3 Yellow//---- input parametersextern int BBI_Ma1 = 3;extern int BBI_Ma2 = 6;extern int BBI_Ma3 = 12;extern int BBI_Ma4 = 24;extern int Boll_Ma = 50;extern int Boll_P = 2;extern int Ma_Method = 0;//=0:Simple moving average,=1:Exponential moving average,=2:Smoothed moving average,=3inear weighted moving average//---- indicator buffersdouble up[];double lower[];double BBI[];                              double BBI_std[];//standard deviation       double BBI_av[];//average                  double BBI_av2[];

       BBI_av[limit] = iMAOnArray(BBI,0,Boll_Ma,0,Ma_Method,limit);  

       limit --;     }
