If you are looking for BO and margin benefits, still finvasia is better among others..
extra charge to enable BO/leverage is nothing when compared other charges levied by other brokers.. assume 4 trades in day ...8*20=160, 160*24=Rs 3840 saved in brokerage alone.. here i considered rs 20/order, if you trade bulk qty, then there will be a spilt in same order qty, leads to multiple legs of order , and may lead to pay upto rs 200 per trade as brokerage alone..
apart from brokerages , other charges are also less in finvasia, compared to others
