Never ever do that blunder as I did.Their funda is very simple.They know that most of the traders loose in trade.And in most of the cases they do not generate enough broke before loosing their investments.So they take that in advance and then only the real story begins.Heres my story.
The market watch will never stream properly.During the first hour of market it will automatically log off while you place your orders.And it will remain in a "Kavi Han Kavi Na" mode, the rest of the day.
After repeated phone calling at your expense, at the help desk, you will be advised with newer versions of "Do This Do That", but your problems will never get cleared.They will forward your snag to their Tech Dept, who will never call you back.
Dont get astonished to find part of your funds debited from your ac unacceptable to you.In my case they charged Rs 1000 (by default while you start trade without selecting a limit card) in last week of Feb and on 31-03-2009 they again charged Rs 5000 !!!
Hence in a nutshell, search for some other broker, pay more and take their worth.
