Simple Query

Suppose i write a 6000 Dec 2010 call and a 6000 Dec 2010 put. How do i square off my positions? Is it like futures where i buy back the futures to square off my short trade? Thanks in anticipation.

yes you have to buy is back the same amount just like future or you can square off your position well it is also depand on the broker if you are in rk global you have to buy back and if you are in karvy you can square off you position .

Sir, i am a bit confused. What is the difference between "buy-back" and "square-off"? Can you please illustrate with an example? Thanking in anticipation.

Yes. You simply buy it back from market to square off. Exactly similiar to futures.

Ensure you buy back same expiry date and strike price. i.e. if you sell 6100CA/Dec10, then you buy back 6100CA/Dec10 only to square off.
