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
Fixed-Fraction Sizing Example calculates trade quantity dynamically using an Average True Range (ATR) stop distance. Long entries trigger when price crosses above a 50-period simple moving average, and positions exit via an ATR-based stop loss level placed below the entry price. Input parameters allow users to adjust the equity risk percentage and ATR length. The strategy plots the moving average directly on the price chart.

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
