Consists of 2 candlesticks where the first candle is a down candle. Both candles should have fairly large bodies and small or non-existent shadows. The second candle is a bullish candle that closes above the midpoint of the first candle.
NOTE:
This is only a valid formation when at a key level of support and I like to see a new low on the second candle.
TRIGGER:
Like the dark cloud cover, I don't often use this formation for a trigger into a trade but rather for confirming a bullish reversal.
