The first doji candle marks indecision between bull and bear. The second doji gaps in the direction of the leading trend. The third changes the attitude of the market once the candlestick opens in the direction opposite to the trend. Each doji candle has a shadow, all comparatively shallow, which signify an interim cutback in volatility."
