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
A lookback setting decides when a zone is invalidated and a tolerance margin allows small breaches. Algorithm modes range from looser to strict engulfing, with a threshold for big versus small candles. Settings limit maximum zones and history, with a separate cap for break, retest and choppy zones. It highlights areas only and has no trade rules.
- Zones from engulfing candle patterns
- Lookback and tolerance for invalidation

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