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

Setups are marked on the price chart with a stop past the sweep, a fixed ES or NQ point target and an optional breakeven at +1R. A text box accepts a pasted gamma level map, which is drawn as levels. Settings cover which sessions are active, the sweep window length and trades per session. It also shows a results table and alerts.

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. Check it in the Strategy Tester and on a demo account before you rely on it.
