I think if we trade bank nifty futures it will cost more in comparison to trading in options correct?
I mean brokerage will be almost same but other charges …trn. charges-gst-turnover --STT etc. - please advise
Yes, you can check for yourself on Brokerage Calculator.
But both are different, Futures move in tandem with Underlying while Options do follow the underlying but there are other factors that play vital role in pricing as well, which makes them trading more complex than Futures.
Well to my surprise charges for options was more than futures. Can you check?
