HDFC Securities has too much brokerage. its amc(annual maintanence charges) is also too high. if you are a intraday trader then you have to pay nearly 2.5% daily if you are trading with nearly 10 trades in a day, which is very high. for positional trader(means short term or mid term or long term) then you have to pay nearly 2.5%. and this brokerage would also apply in case of loss incurred by you.
