When a winning bid is not a winning bid
I watched this auction count down to 0:00 with my bid being the winning bid. I had the winniñg bid of 30$ with a maximin bid of 41$. The only 2 bids the entire auction were mine. (my original bid and my increased max bid). 2 mins later the auction shows there were 4 bids and the winning bid of 42$ went to someone else. What am I missing ?

·2 years agoThe countdown you see is not a real-time feed of bids coming into eBay's servers and the eBay clock counting down. Rather, it is a script that runs on your computer and calls for updates on the auction status about every 3 seconds. It uses the time remaining from those updates to start your own computer's clock counting down from the time the page loads or the last successful update, and displays the "current price" and your status as of the last successful update.
Meanwhile, on eBay's end, a bid coming in is timestamped before eBay does anything else with it. If it gets the timestamp before the end of the last second of the auction, it is a timely bid. Then the bid must be processed to see that it is a valid bid for that item (meets the currently calculated minimum bid amount, not subject to a seller block or over the Buyer Activity Limit or from an account with a bidding suspension, timestamped before the end of the auction) before it is handed over to the server that is calculating the status of the auction. This is usually all done in a fraction of a second, but sometimes can take a couple of seconds. Only after the status server calculates the new "current bid" and leader is that information available to be sent in response to an update request from your computer (and it takes some fraction of a second for your request to get to eBay's servers and another for it to get back, get loaded into RAM, and get displayed on your screen, and the script runs the clock down from when the new "time remaining" loads in RAM, which usually results in your countdown being slow because of the time lag).
So, between the 3 second (at best, not all updates are succesful) gaps and the time to process a new bid, there is always at least a 1-4 second window at the end where the results of a new bid will NOT display on your countdown screen before YOUR clock reaches 0 and the script calls for a full refresh of the Item Page. At that time the results of the late bid usually come up (you are not seeing the actual bid, you are seeing the calculated "winning price" or "current bid"), but I always (and everyone should) give it a few seconds and then manually refresh just to be sure before relying on the result as final (again, on a busy night it might take a few seconds to finish processing a bid). It didn't show until "2 mins later" because THAT is when you took some action (refreshed the page, went to pay, etc.) that caused the updated information to be transmitted to you.
If you bid your TRUE maximum, it doesn't make any difference whether you saw the bid before your countdown ran out--if you had been able to react to it before the auction ended you wouldn't have reacted anyway, since you would not let yourself bid more than the MOST you would be willing to pay. If you did not bid your TRUE maximum and were unable to react, now you know why it is important to bid your true maximum REGARDLESS of what anyone else appears or doesn't appear to be bidding. Highest bid received (but not cancelled/retracted) before the auction ends win, but the price is set by the high bid of the SECOND highest bidder (again, as of what is received but not cancelled/retracted before the end) so it is not necessary to take into account what others have bid, what you guess they have bid, or what you guess they MIGHT bid (except to assume it's about the same as you so add a few cents to the round number you think is your TRUE maximum as a tie-breaker) and expecting to react to other bids as they come in is a recipe for losing at less than you are willing to pay.

There isn't any way for bids that come in at the very very end of the auction to be seen until after the auction ends. Click the number of bids on the auction listing to see the bid history and use the option to see automatic bids. If you need help understanding what you're seeing there, post back with the item #.
