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
RSGAlgo (Range/Support/Gap) calculates range bounds using a percentage threshold over a custom lookback period and highlights consolidation zones with background coloring. Support and resistance levels are established using pivot highs and lows, while gap logic detects price jumps and potential gap fills. ATR multipliers assist in defining risk boundaries. Users can adjust lookback lengths, volatility sensitivity, pivot parameters, and toggle visual elements on the price overlay.

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.
