English Auction
Create an auction for an NFT collection, price starts low to high
The standard for art, antiquity and real estate auction sales is the English auction. Even this standard can contain minor variances but ones that are nonetheless important to understand in order to develop a successful bidding strategy. As the most popular auction type, the English auction pits bidders against each other with the eventual winner being the highest bidder.
In the typical English auction, participants bid against each other. Bidding begins either with an opening bid from the participants or from the auctioneer. Bidding progresses when a bidder offers a higher bid and continues until the last bidder is standing. Bids can be announced by the auctioneer or by the bidder himself or by a third party as in a proxy call. Today, bids are also received via electronic media.
In certain cases where arrangements between prospective bidders and the auctioneer have been prearranged, a bid can be offered by the auctioneer. The English Auction ends when bidding stops. At this point, the highest bidder pays the successful bid price and claims the item. In most English Auctions, the seller establishes a minimum sale price, also known as the “Reserve Price.” The auctioneer cannot sell the item for less than this price.
In many English auctions, the auctioneer establishes an incremental amount. Each progressive bid must exceed the previous bid by at least the incremental amount. The fact that the current highest bid is known to the participants adds interesting degrees of strategy to this type auction.
