Bullish Engulfing Pattern
Description: A bullish engulfing pattern occurs when a small bearish candlestick is followed by a large bullish candlestick that completely engulfs the body of the previous candle.
Significance: It indicates a potential reversal of a downtrend into an uptrend.
Timeframe: Works well on daily, 4-hour, and 1-hour charts for significant signals, but it can also be used on smaller timeframes for short-term trades.

Bearish Engulfing Pattern
Description: A bearish engulfing pattern occurs when a small bullish candlestick is followed by a large bearish candlestick that completely engulfs the body of the previous candle.
Significance: It suggests a reversal of an uptrend into a downtrend.
Timeframe: Similar to the bullish pattern, it is most effective on higher timeframes like daily and 4-hour charts.

Why It Is Useful
1. Reversal Signal: The engulfing pattern is a clear indication of a trend reversal, making it valuable for entering trades.
2. Volume Confirmation: Often accompanied by increased trading volume, adding reliability to the signal.
3. Context: When identified near support/resistance levels or key Fibonacci retracement zones, it becomes even more powerful.

Here is an illustration of the Bullish and Bearish Engulfing candlestick patterns.
