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
Each of five lines has its own filter mode (No Filter, Smooth or Zero Lag), kernel type (Rational Quadratic, Gaussian, Periodic or Locally Periodic), lookback window, weighting and level. A lag setting controls crossover detection between lines, so lower values react earlier. Fast, medium and slow lines can be compared to read direction. It needs the imported library and has no documentation beyond input tooltips.
- Five configurable kernel regression lines
- Four kernel types
- Smooth and zero lag filter modes
- Lag setting for crossover detection

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.
