Am I reading correctly for economic numbers, the cheapest you can get is MNI for $2,500 a month, for corporate news, ravenpack for $10,000?
Dow Jones News Service at Esignal, about $100 a month is pretty fast, I do not know if it is machine readable. You'll probably not beat a Goldman Sachs on it.
For AlphaFlash (basically MNI directly through DB), the pricing is $7-10K a month. API is TCP/IP, although they also have a cheaper $250 a month service through CQG and TT, but that's not low latency and not comparable. Latency is 7-10 milliseconds, and they own the Chicago PMI number (DB) so they have an advantage over reuters/u of m, ism situation. Thomson-Reuters pricing is on par with the Bloomberg number quoted earlier...
That might be interesting. It's not all about being faster than whatever leading firm. Plenty of guys make money trading manually listening to a squawk
IQfeed offers news data (From BusinessWire/PRNewswire/Dow Jones, etc.) through its TCP/IP socket, also historical data for 30-45 days including full-text and headlines. This is at no additional cost to the subscription feed. Obviously not ultra-low-latency, but it still brings an opportunity. Seems to be the cheapest provider.
IQFeed's latency is about on par with the standard Dow Jones feed that you see embedded in applications like Realtick, CQG IC, etc. So, it still can give you some leverage. Given that Reuters/Bloomberg subscribe to DJ news too and import it into their respective feeds for their clients, it shouldn't be too different. It should be the same speed that which DJ news is sent to a Reuters/Bloomberg Terminal, which should be akin to Realtick or CQG or Esignal/Tradestation.
It's what you see here, but it appears to be DJ commodities news + agricultural news + energy news only through the energy/agricultural news supplements: http://www.iqfeed.net/index.cfm?displayaction=data§ion=fees The data is time-stamped and machine readable. There are some other services like marketwatch (owned by DJ/News Corp), 'MidnightTrader' and 'the fly on the wall', which together with AP might partially supplement DJ, but you couldn't guarantee anything.
