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

Inputs limit pattern error, flatness, maximum retracement and optionally bar ratio, and an option avoids overlapping patterns. It draws pattern lines, pattern labels, pivot labels and the zigzag, with theme and size choices. A repaint switch is available, and pattern detection depends on chosen swing parameters. It imports several external libraries.

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.
