下面这个变色均线，本来是以均线方式来显示的，但存在多空颜色转换的问题（yellow），所以我把DRAW_LINE改成了DRAW_ARROW，想用图形代码（圆点）来显示，但显示出来的不是圆点，而是”X“，感觉问题出在最后COLOR CODING处，请大神帮忙看看该怎么修改，谢谢 #property copyright "Copyright ?2006, FX Sniper and Robert Hill" #property link "http://www.metaquotes.net/" //---- indicator settings #property indicator_chart_window #property indicator_buffers 3 #property indicator_color1 Yellow #property indicator_color2 Green #property indicator_color3 Red extern int MAPeriod=19; extern int MAType=1; extern int MAAppliedPrice = 0;//0=close, 1=open, 2=high, 3=low, 4=median(high+low)/2, 5=typical(high+low+close)/3, 6=weighted(high+low+close+close)/4 extern int BarWidth = 1; //---- buffers double ExtMapBuffer1; double ExtMapBuffer2; double ExtMapBuffer3; //---- variables int MAMode; string strMAType; //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { IndicatorBuffers(3); //---- drawing settings SetIndexBuffer(2,ExtMapBuffer1); SetIndexBuffer(1,ExtMapBuffer2); SetIndexBuffer(0,ExtMapBuffer3); SetIndexStyle(2,DRAW_ARROW,STYLE_SOLID,BarWidth); SetIndexArrow(0, 159); SetIndexStyle(1,DRAW_ARROW,STYLE_SOLID,BarWidth); SetIndexArrow(0, 159); SetIndexStyle(0,DRAW_NONE,STYLE_SOLID,BarWidth); SetIndexArrow(0, 159); switch (MAType) { case 1: strMAType="EMA"; MAMode=MODE_EMA; break; case 2: strMAType="SMMA"; MAMode=MODE_SMMA; break; case 3: strMAType="LWMA"; MAMode=MODE_LWMA; break; case 4: strMAType="LSMA"; break; default: strMAType="SMA"; MAMode=MODE_SMA; break; } IndicatorShortName( strMAType+ " (" +MAPeriod + ") "); //---- initialization done return(0); } //+------------------------------------------------------------------+ //| LSMA with PriceMode | //| PrMode 0=close, 1=open, 2=high, 3=low, 4=median(high+low)/2, | //| 5=typical(high+low+close)/3, 6=weighted(high+low+close+close)/4 | //+------------------------------------------------------------------+ double LSMA(int Rperiod, int prMode, int shift) { int i; double sum, pr; int length; double lengthvar; double tmp; double wt; length = Rperiod; sum = 0; for(i = length; i >= 1 ; i--) { lengthvar = length + 1; lengthvar /= 3; tmp = 0; switch (prMode) { case 0: pr = Close[length-i+shift];break; case 1: pr = Open[length-i+shift];break; case 2: pr = High[length-i+shift];break; case 3: pr = Low[length-i+shift];break; case 4: pr = (High[length-i+shift] + Low[length-i+shift])/2;break; case 5: pr = (High[length-i+shift] + Low[length-i+shift] + Close[length-i+shift])/3;break; case 6: pr = (High[length-i+shift] + Low[length-i+shift] + Close[length-i+shift] + Close[length-i+shift])/4;break; } tmp = ( i - lengthvar)*pr; sum+=tmp; } wt = sum*6/(length*(length+1)); return(wt); } int start() { double MA_Cur, MA_Prev; int limit; int counted_bars = IndicatorCounted(); //---- check for possible errors if (counted_bars<0) return(-1); //---- last counted bar will be recounted if (counted_bars>0) counted_bars--; limit = Bars - counted_bars; for(int i=limit; i>=0; i--) { if (MAType == 4) { MA_Cur = LSMA(MAPeriod, MAAppliedPrice,i); MA_Prev = LSMA(MAPeriod, MAAppliedPrice,i+1); } else { MA_Cur = iMA(NULL,0,MAPeriod,0,MAMode, MAAppliedPrice,i); MA_Prev = iMA(NULL,0,MAPeriod,0,MAMode, MAAppliedPrice,i+1); } //========== COLOR CODING =========================================== ExtMapBuffer3 = MA_Cur; //red ExtMapBuffer2 = MA_Cur; //green ExtMapBuffer1 = MA_Cur; //yellow if (MA_Prev > MA_Cur) { ExtMapBuffer2 = EMPTY_VALUE; } else if (MA_Prev < MA_Cur) { ExtMapBuffer1 = EMPTY_VALUE; //-1 red/greem tight } else { ExtMapBuffer1=EMPTY_VALUE;//EMPTY_VALUE; ExtMapBuffer2=EMPTY_VALUE;//EMPTY_VALUE; } } return(0); }
