>>>>Hi all! -- I've got a project in the gestation stage that will need to get current stock prices and to look up stock symbols. Is there a web service out there that hosts this information? If not, is there some non-proprietary method for getting the information other than going to some place like E*Trade?

Hi Jordan. On the bottom of the Yahoo page it clearly states you cannot redistribute the data. Thats to be expected since if you could then how do Reuters, Bloomberg, etc, who are the source of the data make money from it.

In respect of using it in your own app's for your own use I am not sure. I imagine that a Yahoo would buy their real time data and display it on their site in order to get users to view their pages and thereby see their adverts. That is their business model. If someone screen scraps the data then they are bypassing the adverts and therefore losing Yahoo advertising revenue. Clearly in that scenario Yahoo (or whoever) makes no money and one would question why they would allow it?

I am only playing devils advocate here and am not stating a fact but rather a laymans opinion. I have noticed over the years that real time data vendors and stock exchanges have become more, not less, protective of their data.
