I'm working on an online auction site. We're working on functionality to make the user dashboard auto-update without refreshing, so a user can see bids update real-time. The bid price and time updates, along with the badge as the user is outbid or has won the item
We've come up with an idea to subtly highlight the tile when a new bid comes in. However our user won't realize it updates unless there happens to be a bid soon after they land on the page. They may also see the highlight, and no other bids come in for a while.
I'm looking for thoughts on what the right direction is:
Should we just put a one-time notification to inform the user that they don't have to refresh?
Or should we add a constant reminder in the form of a loading gif to indicate it's still communicating?
Should we just leave it be and let the user discover they don't have to refresh the page?
Update
Took your advice. You can see the result in the gif:
