When using Heikin-Ashi Candlesticks, a doji or spinning top in a downtrend is not right away bullish. It just shows indecision within the downtrend. Indecision is the first step to changing direction. Confirmation of a directional change (trend reversal) is required though. Once chartists spot a doji or spinning top in a downtrend, it is time to set a resistance level upon which to base a trend reversal.
