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 band basis can be an SMA, EMA, SMMA, WMA, or VWMA, with adjustable length, source, standard-deviation multiplier, and horizontal offset. Default EMA lengths are 21, 50, and 200. A fill shades the space between the upper and lower bands, and another fill between the shortest EMA and the band basis changes color when that EMA is above or below the basis. It does not generate entries, exits, or stop levels.

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.
