The market is in an uptrend;
The first candle is white;
The second candle is black with a long real body that fully contains the first candle;
And, the third candle is black with a close lower than the second candle.
The first candle marks the beginning of the end for the prevailing trend as the second candle engulfs the first candle. The third candle marks an acceleration of the reversal as there’s a failure to surpass the second candle to maintain to the prior trend
