Last two candls are bullish,with last one as doji,can v consider this bullish harami or color of doji has to be different?

Whenever you face a Doji. Go one time frame lower and try to see what has happened one time frame lower in that. In this case in Reliance we are seeing a very particular kind of behaviour. Price opens higher but it never crosses above that and finds selling pressure at the top. At the fag end of the day there is some short covering though. But under any case we are not breaking the highs of the day. This one cannot be called a Bullish Harami under anycase. The bigger body should have been red. The large green candle has already signalled a trend reversal in the large downtrend.
