Bullish Abandoned Baby
A long black day is followed by a Doji that gaps in the direction of the trend. Then a white day occurs gapping in the opposite direction with no overlapping shadows.
In a downtrend or within a pullback of an uptrend, the market gaps down but does not continue its downward movement. Instead enough bulls step up to bring supply and demand back into equilibrium and the stock churns in place. This isn't necessarily bullish, but it's certainly less bearish. The pattern is confirmed by the next day's gap up and rally.
