Single post in Trade Subforums

Another possibilty would be to use some sort of tag for threads that could be filtered. So when creating or editing a thread you could choose one or multiple tags that would ideally be shown with different colors for ease of recognition. In the forum you would see those tags in the title of the thread. These tags could be used for normal trading threads as well as shops so people see what is being traded easily. In the best case, these tags could then be filtered.
