Why doesnt my above code execute trades at the moving average value? They always trade several pips above or below....seems quite random. According to the above code, if the Ask price falls 3 pips below the 5 day MA, i want to trigger a buy. But as i said before, the bys get triggered randomly, sometimes as much as 50 pips away..
