TC ji let me try to answer that one for you. Yesterday the underlying closed super bullish. I took home calls of 24500 at around 70 with an understanding that even if were to open gap down (for whatever reason) then also the premium would erode by 20-30 points and give me time intraday to plan my next move. I would have based my sl on the underlying and also would have tried bringing down my strike price if we were lower but still above my sl. Now look at the risk i have avoided. Had it gone 200 points against my views i would have incurred a loss of 200 points in future. In options my loss would not have been 30 points as today is the first day of the new week.
