Where is the bloomberg link ?
This looks like the bloomberg terminal, not the bloomberg website.
The terminal is available to wall street/investment banking professionals and costs tens of thousands per year
WTF extra the terminal offers over publicly available live data ?
Live data from exchanges tend not to be free as most exchanges will charge to access live data. What you see from Yahoo finance is likely data from ACRA or another smaller exchange (unless this fact has changed semi-recently)
Bloomberg also provides a news/wire service to subscribers as well as a messaging platform.
It is very expensive and I honestly cannot understand how banks justify buying even one subscription (they need to buy a subscription for every person that uses it).
