The long - tailed doji is, however, a
bullish signal for a couple of reasons: 1, the long lower wick is
bullish; and
2, the size of this
candle is very large relative to any other candlestick in the image.
Even if the daily TF has formed a bearish pinbar, the
2 hour TF is in a down trend but the
bullish engulfing
candle shows a reversion to the mean.
