The first gap up signals a continuation of the uptrend and confirms strong buying pressure. However, buying pressure subsides after the gap up and the security closes at or near the open, creating a doji. Following the doji, the gap down and long black candlestick indicate strong and sustained selling pressure to complete the reversal. Further bearish confirmation is not required. Although the open and close are not exactly equal, the small white candlestick in the middle captures the essence of a doji.
Indecision is reflected with the small body and equal upper and lower shadows.
In addition, the middle candlestick is separated by gaps on either side, which add emphasis to the reversal.
