a downside Tasuki Gap forms on a downtrend. A black candlestick forms after
gapping down from the previous black candle. The color of the first two candles
is the same as the trend. The next day opens higher and closes higher. (The
last two candles are about the same size). If the gap filled, then bearish
sentiment has ended. If not, many traders go short.
an upside Tasuki Gap is just the opposite. The pattern forms on an
uptrend. The first two days are white candlesticks with an up gap from
the first to the second. The third day is a black candlestick opening within
the body of the second candlestick and closing within the gap between day one
and two. The third day does not close the gap.
