I personally use bloomberg+reuters (both paid) and we have a Squawk box... You can use
Bloomberg - Business Financial News, Breaking News Headlines but thats delayed around 10-15 mins .. and
FutureSource.com | Futures, Forex Analysis for charts which are again delayed by
some minutes.. I doubt anyone will provide live feeds free of cost.
Also You can get a very cheap subscirption of CNBC on plus.cnbc.com,
they are almost instant on any major news.
