The bearish harami is more bearish than a doji because it is a defined reversal pattern, while a doji only signals indecision. The bearish harami is considered more bearish since it is a reversal pattern. In contrast, a doji is not a reversal pattern; instead, it merely indicates a state of indecision or uncertainty about where the price will go.
Both Doji and Bearish Harami patterns can indicate a reversal from a bullish to a bearish market, but a Bearish Harami usually gives a stronger signal as it includes two candles and more clearly shows waning bullish momentum.
A doji becomes directional only with confirmation; the harami already implies it.
