we wrote Flat to positive opening is expected with mixed bias ..yesterday's attempt of bulls to penetrate 20 and 50 DMA was repelled by bears and they were too active that bulls were not able to hold even 20 DMA and till closing time bears were celebrating for their victory .the reason of fall was announcement of SBI to increase deposit rate interest by 50 to 150 basis points . ...Volatility may be there as possibility of profit booking in few stocks won't be ruled out ... advised to learn to become successful trader ...and it is quite easy ...
same was the session..
