I'm a new player so I don't have much experience with BLO probably under 100 or 75 hours at this point. I have multiple trade licenses in a few cities most of which are Advanced or Merchant licenses in a few cities. even though I have these licenses I can only post 5 items to the market at once, even if they are of different classes(for example I would post 2 leather to the trader, 2 weapons to the weaponsmith, and 1 piece of armor to the armorsmith.). Even with a merchant License, I can't seem to sell more than 5 items at a time in any city.
