Engulfing Candle
Candle whose body fully covers the previous candle's body - reversal signal.
Bullish engulfing: a red candle is followed by a green whose body fully covers the previous red. Shows buyers took control. Bearish engulfing - opposite. Stronger with high volume and deeper coverage.
In plain words
After a down candle, a much bigger up candle appears that eats the first one - buyers suddenly stepped in hard.
