What are some of those features?
Terminals cost so much becuase the quality of the data and features that they have cost a lot. For starters, there are not many APIs out there that will give you live equity, fixed income, options prices, etc. for free.
This is a data problem, not a software problem. The solution isn’t open source, it’s regulation. I’m an American, so I don’t know much about EU markets, but I’m under the impression they have more mandated transparency in fixed income via ESMA https://www.esma.europa.eu/issuer-disclosure/electronic-repo...
Will that happen? I don’t know. We still use CUSIPs over OpenFIGI, paying for all that S&P licensing, despite a great free alternative. Slow moving industry.
OpenBB doesn't own any data. But by providing an open source infrastructure, any data can be hooked up into a single platform.
So your argument about BBG isn't valid, because with what we are building there's no reason why OpenBB couldn't integrate with BBG data feeds (if they were open to it).
Regardless, I agree that the Bbg comparison is more for marketing. Our approach is substantially different for a different market.
