Hi,
after experiencing IB, im sure you will be disappointed with Indian online brokers when it come to options trading. They charge you exhorbitant margins and some even dont let you sell options
, so forget spread trading online. Also they dont have any idea about the lower risk of spread trading rather they want the full margin for the option you write plus the cost of th eoption you buy. If you find any broker who is good let me know
regards
Dilip
