How do I make a trading station? (without mods) (probably solved)

[Gween]

As title says, I would like to build and set up a trading station. I already built a big station with lots of different storage containers and I would like to use it as a trading hub. Sadly I can't find a way to create buy offers without putting a production module on the station.
I guess I can manuallly make my traders to carry the wares from my stations to this trading hub, but that's not what I'm looking for. I want that my traders automatically carry the wares over to the station and the stations becomes a "supermarket" where you can get everything, for AI traders.
So is there any way, to manually create Buy/sell offers for a station without attaching corresponding production modules to it? And if not, is that a feature that's gonna come in the future?

just fill a ship with 1 unit of all wares you wish to trade an transfer them to the station.
Than use the logistical overview to set the trade offers.
Sadly the vanilla trader ship ai is not optimized for tradestations.

So, once the station has 1 unit of the ware it'll create buy/sell offers for them? I gotta try that later. Thank you

One cannot set the buy limit above the sell limit. This prevents automation of your trade station. It is needed to avoid degenerate loops where a station orders subordinates to trade the same ware between itself.
