Three Black Crows
As the name suggests, the three black crows candlestick formation consists of three large, consecutive, declining candles. The formation precludes lower prices, especially after a strong advance higher. The three candles should all close near the lows of the bar and ideally each bar should open within the prior sessions real body. If the first candle in a three black crows formation is a gap, then this rule is not necessary. The three black crows pattern requires the trader have patience or even wait for a countertrend rally before looking to take a short position or sell out of longs.
