Create Auction Transfer
Step 1: Select the player you want to bid on and click "Transfer".
Step 2: Set the auction floor price and auction time you want. When done, click "Submit" to post the player for sale on Marketplace. During the auction period, if you think that the price offered by another user is reasonable with your intentions, you can end the auction earlier than the deadline.
If you don't want to sell players anymore, you can choose "Cancel Transfer" to withdraw players from Transfer Market.
