A man after my own heart.

Well....... short answer: Not really, but there are some pretty good attempts at it. A game by Origin called Space Rogue is definitely worth a look. I've recently reviewed it on the Amiga Games Database, and there is quite a detailed thread about the game on the comp.sys.amiga.games newsgroup.
Not trading, but space combat; Star Crusader is a great game, with an excellent patch by John Girvin, it features a great storyline and some excellent dogfighting - not to mention Stealth missions!
Star Glider 2 was pretty popular, although it never really clicked with me.
Damocles maybe?
Again, mission based and combat oriented is the fantastic Warhead. I'm re-writing a review of this at the moment and hopefully there'll be a thread in comp.sy.amiga.games shortly.
Hope that's some help.
