The Engulfing Bar candlestick pattern is a powerful and easily recognizable pattern used in technical analysis to signal potential trend reversals. It consists of two candlesticks, where the second one completely "engulfs" or covers the first one. There are two types of Engulfing Bars: the Bullish Engulfing and the Bearish Engulfing.

1. **Bullish Engulfing Bar**:

- This pattern occurs at the end of a downtrend and suggests a potential reversal to an uptrend.

- The first candlestick is a bearish (red or black) candle, indicating a downward price movement.

- The second candlestick is a larger bullish (green or white) candle that completely engulfs the previous bearish candle, opening below the previous candle's low and closing above its high.

- The Bullish Engulfing pattern is considered a strong signal of bullish momentum and is often used by traders to enter long (buy) positions.

2. **Bearish Engulfing Bar**:

- The Bearish Engulfing pattern occurs at the end of an uptrend and signals a potential reversal to a downtrend.

- The first candlestick is a bullish (green or white) candle, indicating an upward price movement.

- The second candlestick is a larger bearish (red or black) candle that engulfs the previous bullish candle, opening above the previous candle's high and closing below its low.

- The Bearish Engulfing pattern is seen as a strong signal of bearish momentum and is often used to enter short (sell) positions.
