Stock Trading and Other Things

How can i get real live nse-bse stock quotes for use in my own live charting software ?

I am developing a customised charting software for my own personal use.
I want to get these instant live quotes to feed to my software .
Do they cost or are they freely provided by the stock exchange ??
