Engulfing patterns - where the body of the second candle extends both above and below the first - are reversal signals. Note that this is the opposite of harami, yet indicates the same thing. A dark engulfing pattern is bearish and a white engulfing pattern is bullish. Shooting stars have a small body and a long upper shadow - the opposite of a hammer. This is also a reversal signal, especially when it comes after a doji of indecision.
