Currently, I have two trade folders. Selling and trading, and tentative.
There's also a few characters in important characters.
Eliska and Valerie are not for trade at all, and I'm unlikely to accept offers on Apollo and Voltaire (they need to be kept together too.) But the other four are up for offers.
Honestly, if you send an offer, I'll likely be chill about accepting if they're in either of my trade folders.
