ATR SL + Position Size Calculator [DoctaBot]

2022年5月3日

Props to veryfid for his original script 'ATR Stop Loss Finder'.

The concept is simple. We use the average true range to determine an appropriate stop loss distance based on recent volatility. The original script calculated the stop loss offset from the current candle's high or low. Here, I've added the option to offset stop loss from the recent local low or local high (a better way in my opinion).

I have also added a feature to automatically calculate position size by either dollar amount or as a percent of your account size to suit your risk profile (percent of account at risk per trade). This calculator supports use of leverage to calculate the amount of margin required to open desired position size.
