I talked to Venture bangalore people last week. The offer appears very attractive - for Rs.10K of advance brokerage (6 month validity), they are offering .01% for futures/cash and Rs.20 for options. And for F&O, if you square up same day, there is no brokerage on the seocnd leg. So effectively, that is .005% for futuers and Rs.10 for options! But would also warn people to have a closer look at their other charges (transaction chgs, sebi chgs etc). I figured out from my calculations that these charges are atleast Rs.7-8 higher (Per lot) compared to what I am currently paying at RMoney. Which means, effectively, the brokerage is nearly .01% per side for futures and about Rs.13-14 per option (single side) - which is of course, still cheap.
