how do i draw default MA on chart
Modify one so that it can be selected ?
You can set it up on the cart and make a template of it.

Nurudeen Amedu:
it's already there.
Copy the code of the MA indicator, apply changes as your request, then merge it in the EA !!!
double MA8_0; double MA8[]; int maNameNumber; void OnTick() { drawMA(); ChartRedraw(0); } int OnInit() { maNameNumber = 0; maNameNumber = "A"; MA8_0 = iMA(_Symbol, timeframe, 8, 0, MODE_EMA, PRICE_CLOSE); ArraySetAsSeries(MA8,true); } void drawMA(){ int MA_Thinkness = 3; CopyBuffer(MA8_0,0,0,3,MA8); if (NewBar() || maName == "A"){ maNameNumber++; maName = IntegerToString(maNameNumber); } else{ maName = maName; } ObjectCreate( 0,maName+"8" ,OBJ_TREND ,0, iTime(_Symbol,timeframe,1), MA8[1],iTime(_Symbol,timeframe,0), MA8[0] ); ObjectSetInteger(0, maName+"8", OBJPROP_RAY,false); ObjectSetInteger(0, maName+"8", OBJPROP_COLOR,clrMagenta); ObjectSetInteger(0, maName+"8", OBJPROP_WIDTH,MA_Thinkness); }
here we go , is much easier and straight forward ;)

am looking for code to either draw the default Moving Average or a custom moving average to chart
the most important thing is that i want to be able to choose applied price, PRICE_CLOSE, OPEN, HIGH & LOW
most custom moving average codes do not have this
