Currently market modules are only available on L and XL structures. This means that if a small group wants a market, they have to anchor a L sized structure which because it confers the ability to either build or dock capitals can often draw unwanted attention. It’s not possible to have a more distributed infrastructure with smaller structures that are less of a shiney target.
Blocking smaller groups from having markets is a problem, because markets are really useful in enabling players to collaborate, especially since CCP wants to encourage more local production over trade hub hauling.
Create a M sized “Trade Post” structure that is able to fit one or two “StandUp Market Stall” modules. “StandUp Market Stall” modules work in the same way to “StandUp Market Hub” except that they only provide access to a particular segment of the market e.g. raw materials, production materials, small ships, large ships, drones and ammo, skills and implants, structures and structure upgrades etc. (Exact market divisions to be determined). Another possible way to break up the modules would be to split buy and sell orders. And/or the module could be limited from the L version in the duration of orders allowed (e.g. only up to 1 month instead of 3) and/or range at which orders can be seen or interacted with (e.g. just in system).
The Trade Post would be similar in price and defensive capability to a Raitaru. It would be bonused for market Stall fuel usage.
This solution would allow a player group to stand up a single market for minerals and ore, for example, or have multiple structures to provide the full range of market capability instead of one L structure that does it all. There is still an advantage to having the L structure in that everything is all in one place, and in fact it could even be more expensive to have the multiple small structures if you want the full range of the market covered.
Alternatively, the Trade Post structure may not be needed and Astrahaus could be given the capability to fit a StandUp Market Stall.
