" I'm not clear that if AmiBroker uses which one of the prices to
calculate MA. Does it use Close, Open, High, or Low? "
AB uses whatever you put into it
MA(C,10) or MA(O,10) or MA(H,10) or even MA( RSI(10), 10 ) or MA( (H+L)/2, 10)
what is normal convention is to use the closing price, but that is
just the norm from all the books you read. It just depends entirely on
what you are wanting to calculate
