Reversal Bar. A bar with tail on top and close below midpoint is bear reversal bar. A bar with tail below and close above midpoint is bull reversal bar.
A good looking bull reversal bar after a BGD is always a good trade for a scalp at least[1], vice versa for a good looking bear reversal bar after a BGU, especially when the context is right, for e.g. HTF like daily chart is in trading range and the gap is at the top/bottom of the range.
Also note that a doji before a reversal bar greatly weakens the signal[2].
