Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
In trending conditions it trades a 9 and 20 EMA crossover, and in ranging conditions it fades Bollinger Band extremes. Stops and targets are ATR multiples, with a wider stop and smaller size when volatile. Size is a percent of equity, pyramiding is off, and commission is included. Settings cover each regime's lengths and multipliers.
- ADX and ATR market regime detection
- EMA crossover logic for trends
- Bollinger Band logic for ranges
- ATR stop loss and take profit with volatile-market adjustment
- Percent-of-equity sizing without pyramiding

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
