I'm fairly new to the trade forums here. I had a an open trade with someone that had 100% positive feedback but now this person has been banned for a bad trade. Is there a way to cancel that trade so it's not showing as open anymore?
From this post it will be purged after 60 days.. Open Trades After 60 days, open trades are purged if they haven't received feedback from either user.
Yes, unfortunately once a trade is regarded as open you can't cancel it. The new feature allows it to be purged, or it will leave once both sides complete feedback.
