I was in http://finance.yahoo.com/ and checked the europe tab ( markets are open here atm) you ll see trades updating live, I went to firebug to the Net tab and there was no updates... so I wonder how are they doing that? I can see there is a streamerapi.finance.yahoo.com that actually makes fiddler throw an error.
Anyone knows anything else about this live update?
Really interested in this, would really like to know if they are constantly polling , the updates seem to happen at irregular intervals
found some info here Please note my interest is on the seeminly push aspect of it ( ie view is updated when there is new information)
Cheers
