Overview
Evening Star Pattern (Candlestick Pattern) checks for a strong initial bullish candle, followed by a middle doji or weak candle, and completes when a subsequent bearish candle closes below the low of the middle bar. Configurable inputs allow traders to adjust the body-to-range percentage thresholds that define doji and weak candles, or toggle the indicator visibility. When detected, it highlights the pattern by recoloring the three bars and plotting a downward arrow above the trigger candle.
