This is a bullish pattern signifying a potential bottom. A three candle bullish reversal pattern consisting of three candlesticks:
# A long-bodied black candle extending the current downtrend
# A short middle candle that gapped down on the open
# A long-bodied white candle that gapped up on the open and closed above the midpoint of the body of the first candle.
The star can be a bullish (empty) or a bearish (filled in) candle.
