Kotak Flat vs Religare Trump Account for derivatives

#1
I am planning to get a new account only for derivatives trading. The two options I am considering are Kotak Flat and Religare Trump Account.

In Kotak Flat charge is 499 per month and 9 rupees flat for either 50,000 in Futures or 1,000 rupees in Options.

In Religare, they will charge 2500 fee and charge 0.025% brokerage.

Which might be a better option ?

Will be grateful for any opinions.
