I feel like this would help spur the economy a lot by showing players where they can take their goods to instantly sell them. If I could for example, place a buy order for 500 leather for the LFPG warehouse at a set price people could see the buy order and drop their leather, selling it instantly to me. The Warehouse owner would get their provision obviously.
With the ability to create courier jobs already in the game this feels like the last needed feature to get the economy growing by giving players more information on demands, opportunity etc
