Basically if you choose to list a cards for a 24 hour trade then you must trade your card at the end, regardless of the offers on the table at the end.
-Once you list your card or cards then you cannot take it down or back out of the 12/24 hour trade.
-The 12 or 24 hours ends either at a time set by the trader or if it isn't stated then exactly 12 to 24 hours after their first post.
