Hi Maximo, I know this post is old now but i am new to it. I understand this stop is 3 x ATR but i don't know what ATR period length is. Is it 7 periods or some other number??? I don't understand the code. Thanks Dean |

If the stop setting is < 'less than' 3, the minimum lookback bars used in calculation is 7 bars. This is also the smallest number of bars for 3x ATR. Higher ATR values will calculate with more bars than 7. |
