Bull知道NonlagDOT这个指标是怎样计算出来的吗？小弟初学MQL，它的源代码看不太懂，还请各位高手指点一二。 下面把指标的源代码粘贴上来，让大伙瞅瞅。 //+------------------------------------------------------------------+ //| NonLagDOT.mq4 | //+------------------------------------------------------------------+ #property copyright #property link #property indicator_chart_window #property indicator_buffers 3 #property indicator_color1 Yellow #property indicator_width1 2 #property indicator_color2 RoyalBlue #property indicator_width2 2 #property indicator_color3 Red #property indicator_width3 2 //---- input parameters extern int Price = 0; extern int Length = 10; extern int Displace = 0; extern int Filter = 0; extern int Color = 1; extern int ColorBarBack = 2; extern double Deviation = 0; double Cycle = 4; //---- indicator buffers double MABuffer[]; double UpBuffer[]; double DnBuffer[]; double price[]; double trend[]; //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { int ft=0; string short_name; //---- indicator line IndicatorBuffers(5); SetIndexStyle(0,DRAW_ARROW); SetIndexBuffer(0,MABuffer); SetIndexStyle(1,DRAW_ARROW); SetIndexBuffer(1,UpBuffer); SetIndexStyle(2,DRAW_ARROW); SetIndexBuffer(2,DnBuffer); SetIndexBuffer(3,price); SetIndexBuffer(4,trend); IndicatorDigits(MarketInfo(Symbol(),MODE_DIGITS)); SetIndexArrow(0,159); SetIndexArrow(1,159); SetIndexArrow(2,159); SetIndexArrow(3,159); //---- name for DataWindow and indicator subwindow label short_name="NonLagDot("+Length+")"; IndicatorShortName(short_name); SetIndexLabel(0,"NLD"); SetIndexLabel(1,"Up"); SetIndexLabel(2,"Dn"); //---- SetIndexShift(0,Displace); SetIndexShift(1,Displace); SetIndexShift(2,Displace); SetIndexDrawBegin(0,Length*Cycle+Length); SetIndexDrawBegin(1,Length*Cycle+Length); SetIndexDrawBegin(2,Length*Cycle+Length); //---- return(0); } //+------------------------------------------------------------------+ //| NonLagMA_v4 | //+------------------------------------------------------------------+ int start() { int i,shift, counted_bars=IndicatorCounted(),limit; double alfa, beta, t, Sum, Weight, step,g; double pi = 3.1415926535; double Coeff = 3*pi; int Phase = Length-1; double Len = Length*Cycle + Phase; if ( counted_bars > 0 ) limit=Bars-counted_bars; if ( counted_bars < 0 ) return(0); if ( counted_bars ==0 ) limit=Bars-Len-1; if ( counted_bars < 1 ) for(i=1;i=0;shift--) { Weight=0; Sum=0; t=0; for (i=0;i 0) MABuffer[shift] = (1.0+Deviation/100)*Sum/Weight; if (Filter>0) { if( MathAbs(MABuffer[shift]-MABuffer[shift+1]) < Filter*Point ) MABuffer[shift]=MABuffer[shift+1]; } if (Color>0) { trend[shift]=trend[shift+1]; if (MABuffer[shift]-MABuffer[shift+1] > Filter*Point) trend[shift]= 1; if (MABuffer[shift+1]-MABuffer[shift] > Filter*Point) trend[shift]=-1; if (trend[shift]>0) { UpBuffer[shift] = MABuffer[shift]; if (trend[shift+ColorBarBack] |
