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
EMA 9, EMA 21 & Bollinger Bands calculates standard Bollinger Bands using a selectable basis moving average type, length, and standard deviation multiplier. Alongside the bands, it computes and plots a 9-period and a 21-period EMA. A dynamic cloud fills the space between the 9 EMA and the Bollinger basis line, shifting green when the fast EMA is above the basis and red when below.
- Bollinger Bands with selectable basis MA type
- Dual exponential moving averages (9 and 21 periods)
- Color-coded fill between fast EMA and Bollinger basis
- Configurable standard deviation multiplier and offset

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.
