Overview
The prior candle must have a long body, and the current candle must be a doji or a weak, small candle. A bullish signal also requires a lookback downtrend, while a bearish signal requires a lookback uptrend, both from an imported library. It recolors the two candles and plots labeled arrows above or below the signal bar. Toggles and thresholds control which patterns appear, the lookback length, and body, doji, and weak-candle size. It does not place trades or set exits.
- Bullish and bearish harami detection
- Lookback uptrend and downtrend filter
- Body, doji and weak-candle thresholds

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.
