I did by modding the UI, so the buy offers are visible and the prices can be controlled, works like a charm.
I can post the code, or a link to a working version, if you want.
I managed to make it work great, maybe I can help.
First, if you don't have a 'Trade Subsciption' with another Faction, requiring +30 relations, the offers in your stations are only visible to ships flying past and don't update automatically.
If your station is a bit out of the way, no-one will know what you sell or buy.
So you'll have to handle the buying and selling yourself, until you get good enough relations.
Beyond that, Autotraders and Tatertraders are way too slow for my taste, because of the number of possible trade routes they have to compare.
I really suggest using simpler scripts like Supply and Trade Route and my favourite the Station Mule.
