Nifty is on bull mode. good buying level 15767 - 15785 target 15944 , 15977, 16033.
if nifty opens below previous day closing it will reach 15820,15785, 15767 and buy call option if nifty opens around 15850 and wait for consolidation then if it sustain above 15910, buy cal option and target 15944, 15977.
my suggestion is to wait until price reach 15767-15785 then take a call
