Best Trading Platform

Hi: Can anyone of you please suggest me which is the best platform for intraday trading. I am looking for fast execution of orders and lowest possible intraday brokerage. Your help and suggestions will be highly appreciated.

Also, please let me know something about SMC Online, is it reliable and good? Thanks!

Now a day there are so many trading option available but I prefer online trading. Religare online gives me such a great opportunity to trade online.
