Price negotiation in stock market

Hello Investors/Traders,

How are stock prices negotiated in BSE and NSE? I mean does investor/trader have right to ask for a price? or is it pre set by brokers?

Is there any additional charges to convert BSDA to normal demat account?

Thanks for the answers

I think you should read through: http://zerodha.com/varsity/

Bids/asks are put by investor/traders. Brokers don’t pre-set any rates.

BSDA doesn’t usually have AMC charge, so while converting you might have to pay AMC charge of a normal demat account.
