A long black day is followed by a white day which gaps opposite the trend
and is completely engulfed by the real body of the first day.
In a downtrend or within a pullback of an uptrend, a long black day occurs.
The next day’s gap up comes as a surprise to the shorts who thought
they were sitting on a great position the previous day. Reliability of
the bullish Harami is low, so a strong following day is needed for confirmation.
The bullish Harami is similar to the bullish Homing Pigeon and could be
the first two days of the bullish Three Inside Up pattern.
