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
Bookmap Style Heatmap + Volume Bubbles splits the lookback into price rows and spreads each bar’s volume across the rows it spans. A blue-to-red gradient shows density, and boxes are deleted and redrawn only on the latest bar. When volume exceeds a moving average by a chosen multiple, a bubble appears at the candle midpoint, lime if the close is at or above the open and red otherwise. Bubble size grows at higher volume ratios. Settings control lookback, row count, average length, threshold, colors, and layer visibility.
- Rolling volume heatmap on the price chart
- Adjustable lookback and price-row count
- Blue-to-red volume density gradient
- Volume spike bubbles at candle midpoints
- Bubble size scaled by volume ratio

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.
