today open intersts of puts decreases and calls increases,
what does it mean?
anyone help me to get clear picture on this
answer can given by to style, one is bookish answer, n second is hidden messages in it.
1) today call options been mostly traded, most guys buy calls and most guys sell calls compare to put option.
2) to complete a trade there need to be a buyer for every seller, so if one has to buy a call then one has to sell that call, selling calls need more margin and buying call need less margin, so option sellers r smart crowd ( its just loose consideration, though things vary as per personal style), also one buy call to hedge his/her short nifty,here more margin requires to do that as well, so this type of buyer is also considered to be a smart money, all in all when open interest in call option increases its bearish, suggests smart money expecting market may go down.
Hope this helps as its not a 2 para concept one need to go deep to study everything.This is the best way i can clarify.
