DeMat account

I dont know about banks, but ShareKhan offers good services at low cost. You can trade online as well.

indiabulls is providing low cost demat account.
They will charge you Rs900 initially and Life time free service.

But if your friend is a regular Trader then do not go for low fees charge.
If you are not a regular Trader then go for indiabulls

I think Reliance money is the best demat account. Trading charges are very less comparetively to other brokerage firms. So opt for Reliance money demat account.
