Rahul,
Please remember that the liquidity will be low for Nov Series till this expiry of this month only.On the othere side,if you trade for October series,you are at very higher risk since the Out Of Money options going to be decayed fast compared to "In the Money" Options.
On other ways,the probability of making profit by this period is very less,since the market is so volatile.
Ghosh,
Correct me if i am wrong.
