Three black crows are three consecutive large bearish candles, each opening near the prior close and closing at a new low. Three days of dominant bearish sessions signal extreme selling pressure.
Bears dominate for three consecutive days. Each day opens and sells off; bulls cannot mount any rebound. Three consecutive new lows show extremely heavy distribution; holders stop-loss and panic selling accelerates.
Strong top-reversal signal after an uptrend (win rate 76%). Enter short after the third bearish candle closes. Stop-loss above the first bearish candle's high. Very reliable signal.
All three bodies should be large — small-bodied three black crows are less reliable. Each candle should open within the prior candle's body with no gaps.
