最近看了一个模板用这个指标，看指标参数的英文好像是成交量的意思，把源码发上，请懂程序的给看看（能解释一下指标算法最好了，哈哈） //+------------------------------------------------------------------+ //| T3MA.mq4 | //| Copyright ?2005, Nick Bilak | //| http://www.forex-tsd.com/ | //| modified for VolumeFactor by: ben | //| thanks to Bilak | //+------------------------------------------------------------------+ #property copyright "Copyright ?2005, Nick Bilak" #property link "http://www.forex-tsd.com/" //---- indicator settings #property indicator_chart_window #property indicator_buffers 1 #property indicator_color1 Olive //---- indicator parameters extern string note1 = "Moving Average"; extern int Periods = 3; //12 extern double VolumeFactor = 0.7; //0.8 extern string note4 = "change color in the Colors area too"; extern color MAcolor1 = Olive; extern string note5 = "Display the info in what corner?"; extern string note6 = "Upper left=0; Upper right=1"; extern string note7 = "Lower left=2; Lower right=3"; extern int WhatCorner=1; extern string note8 = "Y distance; add 10 to each MA"; extern int ydistance1=10; //---- indicator buffers double e1; double e2; double e3; double e4; double e5; double e6; double e7; string objectma1; //+------------------------------------------------------------------+ //| | //+------------------------------------------------------------------+ string IntToStr(int X) { return (DoubleToStr(X, 0)); } //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { int ydistance2; IndicatorBuffers(7); //---- drawing settings SetIndexStyle(0,DRAW_LINE,STYLE_SOLID); SetIndexDrawBegin(0,Periods); if( !SetIndexBuffer(0,e7) && !SetIndexBuffer(1,e2) && !SetIndexBuffer(2,e3) && !SetIndexBuffer(3,e4) && !SetIndexBuffer(4,e5) && !SetIndexBuffer(5,e6) && !SetIndexBuffer(6,e1) ) Print("cannot set indicator buffers!"); //---- name for DataWindow and indicator subwindow label IndicatorShortName("T3MA("+Periods+")"); //---- initialization done if ((WhatCorner == 2) || (WhatCorner == 3)) { ydistance2 = 50+ydistance1; } else { ydistance1 = 20+ydistance1; } objectma1 = "banzaiT3"+IntToStr(Periods); ObjectCreate(objectma1, OBJ_LABEL, 0, 0, 0); ObjectSetText(objectma1, "T3 ("+Periods+")", 8, "Arial", MAcolor1); ObjectSet(objectma1, OBJPROP_CORNER, WhatCorner); ObjectSet(objectma1, OBJPROP_XDISTANCE, 2); ObjectSet(objectma1, OBJPROP_YDISTANCE, ydistance1); return(0); } //+------------------------------------------------------------------+ //| | //+------------------------------------------------------------------+ int deinit() { ObjectDelete(objectma1); return(0); } //+------------------------------------------------------------------+ //| Moving Average of Oscillator | //+------------------------------------------------------------------+ int start() { int i,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-Periods-1-counted_bars; limit=Bars-counted_bars; //---- main loop for(i=limit; i>=0; i--) { e1=iMA(NULL,0,Periods,0,MODE_EMA,PRICE_CLOSE,i); } for(i=limit; i>=0; i--) { e2=iMAOnArray(e1,0,Periods,0,MODE_EMA,i); } for(i=limit; i>=0; i--) { e3=iMAOnArray(e2,0,Periods,0,MODE_EMA,i); } for(i=limit; i>=0; i--) { e4=iMAOnArray(e3,0,Periods,0,MODE_EMA,i); } for(i=limit; i>=0; i--) { e5=iMAOnArray(e4,0,Periods,0,MODE_EMA,i); } double a= VolumeFactor; //0.8; double c1=-a*a*a; double c2=3*a*a+3*a*a*a; double c3=-6*a*a-3*a-3*a*a*a; double c4=1+3*a+a*a*a+3*a*a; //T3MA=c1*e6+c2*e5+c3*e4+c4*e3; for(i=limit; i>=0; i--) { e6=iMAOnArray(e5,0,Periods,0,MODE_EMA,i); e7=c1*e6+c2*e5+c3*e4+c4*e3; } //---- done return(0); } /* e1:= Mov(Pr,tPr,mt); e2:= Mov(e1,tPr,mt); e3:= Mov(e2,tPr,mt); e4:= Mov(e3,tPr,mt); e5:= Mov(e4,tPr,mt); e6:= Mov(e5,tPr,mt); c1:= -b*b*b; c2:= 3*b*b+3*b*b*b; c3:= -6*b*b-3*b-3*b*b*b; c4:= 1+3*b+b*b*b+3*b*b; T3MA:= c1*e6+c2*e5+c3*e4+c4*e3; */ //+------------------------------------------------------------------+ [ 本帖最后由 soaring00 于 2008-10-5 18:16 编辑 ]

这个指标中不涉及成交量。 计算过程很复杂，公式如下： 　 e1=EMA(Close,3); e2=EMA(e1,3); e3=EMA(e2,3); e4=EMA(e3,3); e5=EMA(e4,3); e6=EMA(e5,3); 　 a= VolumeFactor; c1=-a*a*a; c2=3*a*a*a +3*a*a; c3=-3*a*a*a -6*a*a -3*a; c4=3*a+a*a*a +3*a*a +1; 　 最后显示出来的的指标线为e7： e7=c1*e6 +c2*e5 +c3*e4 +c4*e3; 　 　 　 　 　 　 [ 本帖最后由 秃鹫 于 2008-10-7 14:17 编辑 ]
