I have been trying to figure out what characteristics affect trade, but am a tad lost. For example, does more speed on a freighter make a route more profitable? When ultradrives were discovered I got the feeling all my routes increased in value by 50% (was not monitoring closely before that), so I proceeded to spend over 4k bcs to upgrade all my traders just about doubling their speed, but I saw no rise in trade profit coming from it. So here's my question:
What freighter characteristics affect trade route values?
1. Speed?
2. Multiple trade modules? (didn't even try to add more than one, not sure if it is even possible)
3. Other?
