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

JoppanFX | Candlestick Patterns checks for bullish patterns (Hammer, Inverted Hammer, Bullish Engulfing) and bearish patterns (Shooting Star, Hanging Man, Bearish Engulfing) using configurable mathematical thresholds. Users can toggle individual patterns, adjust the trend lookback period, tune shadow-to-body ratios, set minimum body-to-range filters, and select engulfing detection methods (Real Body or Entire Candle). Text labels draw above or below detected bars with customizable colors.

Detection of six classic candlestick patterns
Configurable shadow-to-body and body-to-range ratios
Trend lookback filter for pattern context
Engulfing detection by real body or entire candle range
Customizable visual labels and chart colors

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.
