I am a customer of sharekhan from 1 year. I am a trader majorly intraday trader. what you would face in real with sharekhan is as suppose you are a day trader wants to get just 5% in day(which is very low target), and makes 10 trades in a day then, you need a profit of .5% in each trade+ .25% to .30% additional as brokerage and tax. and it would go around 1.5% for positional trading. just look at its brokerage it is just half of your profit target which if very high and its dose not makes sense. I would recommend any discount brokerage which would upto 20 times less than it with all similer benefits.
