Candlestick patterns
A sharp reversal: the second candle opens beyond the first candle's open and runs the other way.
A bullish kicker is a bearish candle followed by a bullish candle that opens at or above the first candle's open, with a gap, and keeps going. The direction has reversed at the open, usually because of news. The bearish kicker is the mirror.
It needs a gap, so it shows up on stocks and futures after the overnight break, and hardly ever on 24-hour forex charts.
