Options and Futures mock /trading site

Hello Everybody,

I want to know if there is any site where one can keep 'Demo Account' for trading in Stock options or futures of indian securities. I mean 'Mock Trading' site for buying and selling in options and futures. I know two sites 'Moneybhai.moneycontrol.com' and 'sens*x.tradeover,net' for mock trading of shares but there is no facility of mock trading in options and futures (derivatives).

Please Help.
