I had opened an account with Alice Blue because they were recommended by an options strategy writer named Market Star Strategy on Tradetron website. After I completed all their formalities, they let me do just one trade in options. After sending many emails/ WA messages along with my bank statement, they enabled it twice but blocked it soon after, and then went into silence. Finally I have requested them to close my account, but no reply from their side.
They are cheap but really their service is also cheap.
