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 Reaction mode it weights candle volume and body size over a lookback window; in Liquidity mode it follows unswept swing levels and profiles their remaining weight. It can mark a point of control, the highest band, an EMA and liquidity lines. The code notes it approximates activity because Pine has no historical order book.
- Right-side heatmap of buy and sell bands

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.
