A Bearish Engulfing pattern is a two-candle reversal formation that typically appears at the end of an uptrend. It occurs when a small bullish (green) candle is immediately followed by a larger bearish (red) candle that completely engulfs the body of the previous candle. This shows a shift in market sentiment as buyers lose control and sellers step in with strong momentum. The larger the bearish candle and the higher the accompanying volume, the stronger the bearish signal. Traders use this pattern as an early indication of potential trend reversal or downside correction, especially when it forms near resistance or after an extended rally.
