I have tried to understand the different aspects of the brokerage houses. I have also looked after the various demat providers. Among the companies that I have studies are RR Finance, Bajaj Capital, SBI Finance, Abhinav Securities, BSE Star MF Platform, HDFC Securities, India Bulls Securities, Sharekhan and Karvy. The more I have read about them the more I feel myself confused. Can you please let me know of a good brokerage house which provides user friendly trading platform, good service and certain other customer friendly facilities?
