This is an educational post. I am not a SEBI registered. The trend is positive so there will be buy on dip on yellow zone . And breakout of green zone will make Banknifty more bullish. Market will be sideways between yellow and red zone and bearish after breakdown of red zone. Profit booking zone are black zones after breakout and breakdown of green and red levels respectively. Also see ema's for bearish and bullish movement.
