Short Trades: A buy stop is placed at [Entry + ATR(ATR_Length) * ATR_Index]. Stop Loss Exit: ATR(ATR_Length) is the Average True Range over a period of ATR_Length. ATR_Stop is a multiple of ATR(ATR_Length). Short Trades: A buy stop is placed at [Entry + ATR(ATR_Length) * ATR_Stop]. | Time_Index = [1, 40], Step = 1; ATR_Length = 20; ATR_Index = [1.0, 6.0], Step = 0.2; ATR_Stop = 6; |
