instantly after someone places a higher bid than your current bid

their highest bid is automatic and will increase all the way to the amount the user input in the highest bid section of the auction – their bid will continue to increase until it is outbid by another user – you’ll need to keep increasing your bid until you outbid that user

As soon as you place your bid, if his auto bid is higher, you will be notified with a red X that you have been outbid. When you have outbid him the green check will come.
