It's a good question. There are many reasons - and I don't think the speed of information is the real one. I almost left a single word response - "chat" - but think it is more complicated. Another aspect is trust. If you are trading billions you want the information/trade data "currency" everyone else uses. I built backends converting MBS bid to yield and if it wasn't tuned to a 1/16 or better of Bloomberg, it wasn't usable. Bloomberg also offers custom studies like "fear/greed" which may have some value. TR/Thompson Reuters also has a competitive product for much less and you can't really go wrong with either for 99% of use cases. There are also many stand alone news sources you could use. Benzinga comes to mind as one example. Interesting note - Bloomberg is highly protective of their IP and has been know to write takedown notices of screenshots posted online. // built 2 SaaS Fintech systems
