@asterix - zerodha isn't any better. I know. I am a disgruntled customer of Zerodha who came to Finvasia solely for NSE NOW platform. Now they reactivated my account with NEST Trader instead of NOW, after few months of inactivity. All the platforms on Finvasia suck big time. Atleast the problems with Kite aren't as worse as this - crashing while putting a buy order, etc. But Zerodha isn't a good platform either - just that it's extremely well designed to use. Scalpert isn't even good in terms of user experience. And see - Finvasia doesn't even reply here anymore. They have stopped caring. A friend of mine applied for account opening two months back, they still haven't opened.
the problem you are saying today happened with NEST, same had happened with NSE NOW few weeks back. you can see my earlier posts, few pages back in this thread.
