Most probably Nifty is about to complete pull back (b) . (b) seems to be in form of an abc flat corrective structure in which wave c is a strong impulse Right now considering alteration we may in wave 4 of the impulse c and if alteration is not considered we may be in wave 4 of 5 of c. The structure will clarify itself in the coming week . But its a topping ot formation for the Nifty .
