Pioneer!

Pioneer is a space adventure game set in the milkyway galaxy at the turn of the 31st century.

The game is open-ended, and you are free to explore the millions of star systems in the game. You can land on planets, slingshot past gas giants, and burn yourself to a crisp flying between binary star systems.

When Pioneer is finished there will be many ways to make ends meet: piracy, smuggling, bounty-hunting, mining, doing missions for the various factions fighting for power, freedom or self-determination.

Pioneer has a sneaking resemblance to Frontier: Elite 2.

This looks like a good game, I might try it out later.

I will find out the answer to your question if I get it.

Actually, I found out myself

Just go to map view: F2 select star system u want, and then prss f7, and go to economic info. You want to buy from the place that has stuff under MAJOR EXPORTING and deliver to MAJOR IMPORTING. There is minor too, but major gives you the best profit margin.
