The 3 Inside-Up candlestick pattern is a three candle bullish reversal pattern with a solid 65% accuracy rate.
This pattern is very similar to the 3 Outside-Up pattern but with the first two candles switched.
The first candle is a large bearish candle that appears in a downtrend.
The second candle is a smaller bullish candle that opens and closes within the body of the first candle. The first two candles can have the same high or the same low, but they cannot have both.
The third and final candle is another bullish candle that closes above the close of the second candle. It also closes above the open of the first bearish candle.
The 3 Inside-Up candlestick pattern is basically a bullish Harami followed by a final confirmation candle.
