The auctioneer does not disclose the current maximum bid, but the second highest bid is always public. In proxy bidding, the wise bidder must know in advance the "true" value of an item as a basis for their secret bidding limit. [2] The fact that the maximum bid is revealed when it is outbid introduces the possibility of maximum bid fishing.
If someone else has placed a bid that is higher than the maximum bid, the will be notified, allowing he to change the maximum bid and stay in the auction. At the end of the auction, whoever's maximum bid is the most wins the lot. Live bidding is a traditional room-based auction.
The intent is to make the high bidders bid above their upper limits. In the final rounds of bidding, when the current losing party has hit their maximum bid, they are encouraged to bid over their maximum (seen as a small loss) to avoid losing their maximum bid with no return (a very large loss).
A bid price is the highest price that a buyer (i.e., bidder) is willing to pay for some goods. It is usually referred to simply as the "bid". In bid and ask, the bid price stands in contrast to the ask price or "offer", and the difference between the two is called the bid–ask spread. An unsolicited bid or purchase offer is when a person or ...

[1] In this type of auction, all bidders simultaneously submit sealed bids so that no bidder knows the bid of any other participant. The highest bidder pays the price that was submitted. [2]: p2 [3]
Proxy bidding is an implementation of an English second-price auction used on eBay, in which the winning bidder pays the price of the second-highest bid plus a defined increment. It differs from a Vickrey auction in that bids are not sealed; the "current highest bid" (defined as second-highest bid plus bid increment) is always displayed.
Consider an auction where a set of identical products are being sold. Bidders can take part in the auction by announcing the maximum price they are willing to pay to receive N products. Each buyer is allowed to declare more than one bid, since its willingness-to-pay per unit might be different depending on the total number of units it receives ...
In the basic model of optimal auction design developed by Roger Myerson (1981), the optimal reservation price (i.e., the smallest admissible bid) is independent of the number of bidders. [8] This basic model of optimal auction design assumes that the bidder's type is known; that is, the seller has asked the potential buyers what their value ...
