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

Pattern Recognition — 101 Patterns + Bayesian Predictor features a complex situation context engine for confluence detection and displays a Bayesian table predicting next-pattern classifications. Visual elements include pattern labels, EMA trend lines (20/50/200), and background shading overlaying the price chart. Chart and harmonic patterns depend on pivot points, meaning historical pattern labels appear after confirmation bars complete.

Detects single-bar, two-bar, and multi-bar candlestick patterns

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.
