You need to call the chart indicator add with the # of the window to add the indicator as its the macd and its in a new window. The total number of indicator windows will suffice for that. Then on deInit you must release and remove the indicator as well. Here is a reference code : int myMacdWindow=0; //+------------------------------------------------------------------+ int OnInit() { macdHandle = iMACD(_Symbol, _Period, macdFastEMA, macdSlowEMA, macdSignalSMA, PRICE_CLOSE); if(macdHandle == INVALID_HANDLE) { Print("خطا در گرفتن هندل MACD"); return(INIT_FAILED); }else{ ResetLastError(); if(!ChartIndicatorAdd(0,(int)ChartGetInteger(0,CHART_WINDOWS_TOTAL),macdHandle)){ Print("Error #"+IntegerToString(GetLastError())); }else{ myMacdWindow=(int)ChartGetInteger(0,CHART_WINDOWS_TOTAL)-1; ChartRedraw(0); } } ArraySetAsSeries(macdMain, true); ArraySetAsSeries(macdSignal, true); return(INIT_SUCCEEDED); } void OnDeinit(const int reason){ if(macdHandle!=INVALID_HANDLE){ IndicatorRelease(macdHandle); ChartIndicatorDelete(0,myMacdWindow,"MACD("+IntegerToString(macdFastEMA)+","+IntegerToString(macdSlowEMA)+","+IntegerToString(macdSignalSMA)+")"); } } As for the debugging , when you click the blue or the green play buttons on the IDE it goes into debugging mode . Click compile and just drag the ea file from the navigator on a chart.
