This indicator plots an ATR-based Chandelier Exit trailing stop on the price chart. It tracks a long stop under recent highs and a short stop above recent lows, then switches direction when price crosses the opposite stop. Buy and sell labels mark those flips.

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
HMD Bollinger Band Volatility calculates standard Bollinger Bands, measures the percentage difference in band width relative to a user-defined lookback period, and identifies maximum expansion and contraction extremes over a trailing window. Plotted directly on the price chart, it renders the middle SMA and outer bands alongside a dynamic background color gradient that visually indicates volatility shifts. Configurable settings include SMA length, standard deviation multiplier, lookback period, and color thresholds.

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.
