A quick note for anyone thinking that this could help you build that finance app you've been putting off - getting actual real-time stock quotes legitimately is actually fairly expensive/involved.
Screen scraping Google / Yahoo finance and using that data in an app is (I believe) explicitly against their TOS. Whether or not they ever enforce that is another story...
The actual real-time data streams are highly controlled and regulated by a few big players.
(Just my $0.02 after having looked into it about a year ago for a social investing app I was building)
- getsat 14y agoThat data is also 15 minutes old (or older!) from what I recall. Probably not your best choice for anything remotely "realtime". As parent said, you're better off getting a real market stream which will probably use FIX: http://en.wikipedia.org/wiki/Financial_Information_eXchange http://en.wikipedia.org/wiki/Financial_Information_eXchange
- nodesocket 14y agoIt should be realtime (not delayed 20 minutes), we will find out in 8 minutes if this is true. :)
- nodesocket 14y agoConfirmed real-time, just streamed in: { "ticker": "AAPL", "exchange": "NASDAQ", "price": "598.86", "change": "-9.48", "change_percent": "-1.56", "last_trade_time": "Apr 19, 9:30AM EDT" }
- getsat 14y agoI was referring to scraping Google/Yahoo. They have disclaimers on their sites that the information is N minutes old at best. EDIT: I guess a few of them are actually realtime now.

- rpledge 14y agoYeah, while this is cool I'm sure it's a violation of Googles TOS. I'm sure they'd enforce it if this gets traction.
