Thanks for your suggestion. My simple answer is that in the last 3 months, I have been consistently making profit in Options. Using Options I am able to manage the Risk using Pairs. I have also started trading naked Calls or Puts recently. But my comfort lies in trading pairs.
If one is trading naked Calls or Puts, In terms "better rewards", I still think Options have a greater rewards than Futures.
I think one has to First conquer Fear and then one can conquer Greed.
Also as per my Trading plan for at least six months, I want to trade with the same instrument (NIFTY Options) and same quantity and consistently make profit. I have 3 more things to complete this rule. I will may be consider trading in Futures and other instruments after 3 months.
