It could be better and that is the point of suggestion sub-forums and threads isn't it?
The intelligence available really is poor considering it is the year 3300. We all realize it is a game but Trading, like most of the systems, really would shine with more tools, info and story behind it. That is the "potential" that everyone keeps talking about the "base" we have today. Same with exploration; FD already said it is a bare-bones framework and they want to put more love into it.
Example with Lave by OP is that Players should be able to find out why pesticides are below cost of a big producer on a consumption planet like Lave. If there is no apparent reason for it then the black box mystery is not satisfying and can lead to many trade losses and player frustration.
Personally I would like to see more trade goods, specifically more manufacturing parts that feed into full products and more specialty or rare goods as well. Why would we truck coca-cola from planet to planet when they could make their own? Every planet will have unique exports that create demand because they are unique. Major weapons producers need to ship parts to shipyards where spaceships are assembled. Hauling pesticides and food to agricultural planets actually makes no sense to me because those are goods that would be cheaper to produce on-planet unless there was a need to import a special pesticide grown only in a few systems.... leading back to some of my other points.
