Hi Would anyone be able to help me to integrate the Heiken Ashi custom indicator into a strategy using the icustom TA block? Im trying to build an EA that opens a buy position when the Heiken Ashi candle turns white, but am not sure which mode to use and how to write the conditions. Here is the code, any advice much appreciated:
//+------------------------------------------------------------------+ #property indicator_chart_window #property indicator_buffers 4 #property indicator_color1 Red #property indicator_color2 White #property indicator_color3 Red #property indicator_color4 White #property indicator_width1 1 #property indicator_width2 1 #property indicator_width3 3 #property indicator_width4 3
//---- extern color color1 = Red; extern color color2 = White; extern color color3 = Red; extern color color4 = White; //---- buffers double ExtMapBuffer1[]; double ExtMapBuffer2[]; double ExtMapBuffer3[]; double ExtMapBuffer4[]; //---- int ExtCountedBars=0; //+------------------------------------------------------------------+ //| Custom indicator initialization function | //|------------------------------------------------------------------| int init() { //---- indicators SetIndexStyle(0,DRAW_HISTOGRAM, 0, 1, color1); SetIndexBuffer(0, ExtMapBuffer1); SetIndexStyle(1,DRAW_HISTOGRAM, 0, 1, color2); SetIndexBuffer(1, ExtMapBuffer2); SetIndexStyle(2,DRAW_HISTOGRAM, 0, 3, color3); SetIndexBuffer(2, ExtMapBuffer3); SetIndexStyle(3,DRAW_HISTOGRAM, 0, 3, color4); SetIndexBuffer(3, ExtMapBuffer4); //---- SetIndexDrawBegin(0,10); SetIndexDrawBegin(1,10); SetIndexDrawBegin(2,10); SetIndexDrawBegin(3,10); //---- indicator buffers mapping SetIndexBuffer(0,ExtMapBuffer1); SetIndexBuffer(1,ExtMapBuffer2); SetIndexBuffer(2,ExtMapBuffer3); SetIndexBuffer(3,ExtMapBuffer4); //---- initialization done return(0); } //+------------------------------------------------------------------+ //| Custom indicator deinitialization function | //+------------------------------------------------------------------+ int deinit() { //---- TODO: add your code here //---- return(0); } //+------------------------------------------------------------------+ //| Custom indicator iteration function | //+------------------------------------------------------------------+ int start() { double haOpen, haHigh, haLow, haClose; if(Bars<=10) return(0); ExtCountedBars=IndicatorCounted(); //---- check for possible errors if (ExtCountedBars<0) return(-1); //---- last counted bar will be recounted if (ExtCountedBars>0) ExtCountedBars--; int pos=Bars-ExtCountedBars-1; while(pos>=0) { haOpen=(ExtMapBuffer3[pos+1]+ExtMapBuffer4[pos+1])/2; haClose=(Open[pos]+High[pos]+Low[pos]+Close[pos])/4; haHigh=MathMax(High[pos], MathMax(haOpen, haClose)); haLow=MathMin(Low[pos], MathMin(haOpen, haClose)); if (haOpen<haClose) { ExtMapBuffer1[pos]=haLow; ExtMapBuffer2[pos]=haHigh; } else { ExtMapBuffer1[pos]=haHigh; ExtMapBuffer2[pos]=haLow; } ExtMapBuffer3[pos]=haOpen; ExtMapBuffer4[pos]=haClose; pos--; } //---- return(0); } //+------------------------------------------------------------------+
