1 May 2008 12:58PM ET Sorry, can't be of much help for Indian markets.
I'd say you contact the stock markets directly, ask them about the protocols they will allow.
For US markets, I'd advise that you use a product like marketcetera rather than code it from scratch.
Good luck. It is not as complicated as people are projecting it to be.
