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
Bands at a chosen number of standard deviations mark stretched conditions where a return toward zero is expected, shown with zone tinting and an optional guide panel. Settings include the differencing order, lag count, Z lookback and layout. Written with Nasdaq futures in mind.

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.
