Since the latest update it was possible to limit ressources in the markets. Now it isn’t possible anymore. Was that intended?
Unfortunately that leads to the fact, that most of my firewoods are stored in the markets. I can’t stop them to carry it to the markets.
Welcome to the forum. 
It has been removed in v0.9.2.
"Zantai:
The way markets were set up, they already automatically manage quantities of items to stock based on availability and needs. This behavior was conflicting with player-set limits, which created some seriously buggy situations, so manual limits in markets were disabled."
Thank you for the link. But then I think it needs a better balance. Actually from my 600 fire woods 540 are in the markets. I raise and raise the limit and it is always going only to the markets.
I now configured min levels on my stockyards to test, if that helps…
Is this a pre-v0.9.2 town or one you started in v0.9.2?
Started it with 0.9.2 playtest.
Played the last 2h. All my firewood is going to my two markets. Only 250 is on my 3 stockyards, but I only managed that by setting there a min leven of 75 on each.
