so many promises made by zerodha when they started off. but sorry to say that almost all promises were NOT taken care off. To say the least check your own web site; it has not changed since ages; all you see is "coming soon"....Now, square off time is pre-poned to 3 pm and also many might not be aware of this: required margin to buy/sell FUTURE stock/index lot (for intraday) is now 40% of the total margin required to hold the position. Earlier the margin was less and was 50% of the span margin. Is this the case the of horse becoming a donkey?
Only drawback with Indiabulls is option brokerage is rs 50 per lot, but I rarely trade in options.
