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
The script plots a histogram of the difference between the current band width and its moving average in a separate pane, alongside the moving average line and a zero baseline. The histogram changes color depending on whether the volatility is expanding or contracting relative to the average. Inputs allow users to adjust the Bollinger Band length, standard deviation multiplier, moving average period, and visual colors.

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.
