If RK GLOBAL gives me zero paise/free I would avoid RK GLOBAL because of my previous bad experience with them.Have closed account with them in 2010.
NSE has sent me sms few days back that whatever trades I do with RK GLOBAL , they would send me SMS.
Either RK GLOBAL did not close my account or NSE data is not updated.
Man ....Any one thinking of opening account with RK Global ..please think a lot...
