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 reversal bar after a BGD is always a good trade for a scalp at least[1], vice versa for a good looking reversal bar after a BGU.
Also note that a doji before a reversal bar greatly weakens the signal[2].
