very common bullish reversal pattern is considered moderately reliable.
black candlestick day is engulfed completely by a long white/empty candlestick the
next day that gaps below the previous day’s low and then rallies to close above
gap down, in a downtrend, is seen as a point where bulls exit the scene. When
the selling ends, shorts rally the stock to close above the previous day’s high.
Confirmation is needed by the evidence of higher volume.
