Sir please add outstanding OI of clients and pro also as now a days 50% of time market moves according to there positions.Now it is not always FIIs which decide market direction.
@durveshkhamgaonkar My advice to you stay away from option buying , you can make profit few days but in long term 2-3 years you will always make loss.Only 0.5% buyers stay profitable after 5 years.So do stock swing trading, no premium decay no losses, longterm always profitable...
