Great work at finding a way to make buy / sell prices a reality!
As an owner of several bases both close to ores as well as mid-route on several areas, I welcome the chance for the base to actually earn without my constant vigilance on the stock levels to see when the buy/sell shift is needed...
My one concern is for the consumer using this setup at the base and making sure they are aware which view they are currently in. My thoughts were maybe an item in the inventory like the Discovery RP 24/7 Server Rules item in your screenshot or the 'Sanction' type I've seen on some POBs around the sector but setup with the Buy/Sell instructions - kind of 'in your face' that you need to do something to change the view?
Otherwise fully supportive! It will hopefully stimulate a bit of interPOB trade routes or short-route trading for those that want to earn but don't always want to run the ENTIRE ore route...
