This has been discussed about 50000 times, with the general points that arise are about the ingame world arrangement which is full of corporate control and greed preventing the free flow of information, and then you'll get gameplay and coding comments that it's already done better by outside elements like INARA so it's a potential waste of effort to include something half-donkeyed that's done far better elsewhere.
That said, personally I'd like ED to set up an internal data feed for API developers, so then at least your need to stay in the same screen would be satisfied. FD can already accomplish enough half-donkey features without trying to crappily replicate a good existing external feature.
Also, stocks in what? Are we talking local, regional, factional, galactic markets? Tied to which section of existing galactic finance or creating a new one? The scale of anything is what I find borks peoples' concepts and expectations in this game.
Originally I was hoping that there would be accumulative data connection, so that the further you went ingame with trading and smuggling the better your network became. I think that ship has sailed however permanently, once we put HERE IS THE CRIMESTORE on the galactic map. >__>
