A bullish engulfing pattern is a bullish reversal candlestick pattern in technical analysis that usually appears after a downtrend, where a small bearish candle is followed by a larger bullish candle that completely engulfs the previous candle’s body. This pattern indicates that buyers have taken control from sellers and momentum may shift upward, signaling a possible trend reversal or strong bounce. It becomes more reliable when formed near important support zones, trendlines, or with strong trading volume confirmation.
