I am not an ambitious trader but I have a thought on this since the ATP plant lists are not a shopping list exclusively for traders to search for wanted items.
At the bottom of each post there is a space to add a line or two. Why not create a link to allow others to find your 'available for trade' plants? This can be in an ATP blog space or even off-site, as in Etsy or eBay or a personal website. I think I have seen some folks who add 'Look at my trade list' or something like that. That link can lead to a list of each plant you have available and another list for each plant you are seeking.
Additionally, many people list what they have currently available for trade on the trading forum, as the availability changes throughout the year.

Very effective system.
That being said, when I click on 'Plant Lists' I am taken to a page with the heading "Plant inventory, trading and selling lists" which does kind of make it look like a list for trading and selling. Maybe change the heading to something like "Member Plant Lists. (Some items may be available for trade or sale; see individual lists for details.)".
