hi salil
i have an online trading a/c with fortis for the last three months.i think its very good. They charge very low brokerage of 0.15% for delivery trades & 0.015% for inra day and derivatives trades. They provide ODIN software free of cost. As compared to ICICI , its a lot better. But ensure that ur a/c is opened in a branch nearest to u bcoz if u want to visit them & use their terminal , then u would have to visit the branch where u have ur a/c.
If u have any specific query, u may plz post it.
