The bearish harami is a two-candle pattern: a large bullish candle followed by a small bearish candle whose body falls entirely within the first candle's body. After an uptrend, it's a potential top signal.
Early sign of weakening upside momentum. The small bearish candle after a large bullish one shows bulls can't continue, and the market enters indecision. Signal strength is low and needs confirmation.
Low reliability (win rate 55%). Wait for a third bearish candle that breaks below the harami's low before entering short. Stop-loss above the large bullish candle's high.
More reliable after a large bullish candle at highs. The smaller the second candle's body (especially a doji), the stronger the reversal signal.
