Increase in OI for 4600PE means Put Writers are not expecting 4600 to break else they will be in loss for selling 4600PE.
Seller of PE will gain if market goes up since price of PE will reduce -- means -- he has sold high and bot low.
Yes charge more for surety, surely, BUT there is more supply since increase in OI so price remaining stagnant -- get it
Nifty is traded only in CE/PE -- CA/PA not allowed.
Also cannot exercise even if CA/PA coz - get the logic - u buy 4700CA for 124 when mkt is 4620 -- how do you expect to profit if it is not above your strike price, then how does one exercise!!!!
We have unlimited supply for answers as like the 4600PE sellers
