I am trying to set up a chain of stations that will have roughly equal amounts of wares between them, but I'm having trouble actually doing it. The goal is to shuttle intermediate wares back to my main base while alsoselling them at a high cost to whoever is desperate enough to need them, but my traders don't want to move them from place to place, even when they are idle and set to only trade with me. Is there a "profit" calculation for moving goods between stations that I need to consider, even if it is all pulling from the same accounts? Or is each station considered to be it's own independent thing with a goal of making money, causing the stations to compete for wares?

If so, is it just a matter of setting up repeat trade orders with transports to do it manually? If so, is there any way to duplicate orders across ships?
