There's a bearish engulfing pattern formed by two candles, the first of which should be bullish and the second bearish. The second candlean engulfing candleindicates that the price is about to reverse course and resume its upward trend. The longer the body of the engulfing candle and the smaller the body of the original candle, the more likely a bearish reversal is. The chance of a reversal is increased and the effect is amplified when the first candle's body and shadows are covered.
