There's an old adage "pick your battles".
People need to wake up and smell the coffee that unless you've got deep pockets, you are never going to challenge Bloomberg (or Refinitiv or CaptialIQ or Factset).
Why ?
Because data. Because LOTS OF DATA.
These companies have global coverage of data. They have global coverage of news. They have decades of historical data. They have live feeds from all global exchanges. They have traceable fundamental data for governments and corporates worldwide. They have presentation transcripts for governements and corporates worldwide. They have analytics tools. They have ... well, you get the gist !
Building and maintaining all those global data feeds costs $$$$$$$ and requires constant maintenance and babysitting to make sure its all functional. The same applies to integrating it all onto one platform to present to the end-user, more time, more money and lots of it.
Bloomberg & Co cost 1-2k a month for a reason. It is simply not possible to deliver it for less than that price point. There is just so much stuff going on behind the scenes before it reaches your workstation.
If you're telling me you can deliver it for 10's or 100's a month, then I can almost certainly guarantee you are cutting corners, lots of corners. So many corners that its pointless.
So, frankly, unless some oligarch has given you a few Billion and told you to get on with it, you're not going to be "challenging" Bloomberg & co, not now, not ever.
