Which type of auction allows for "competitive bidding"?

In an English auction, competitive bidding is a central feature, where bidders openly compete against each other by placing progressively higher bids until no one is willing to bid higher. This type of auction allows participants to see the current highest bid and encourages them to exceed it, fostering an environment of competition.

As the auction progresses, bidders can gauge their chances and adjust their bids accordingly, which can lead to a dynamic and engaging experience. The transparency of the bidding process and the active involvement of participants contribute to the competitive nature that defines English auctions. This is different from sealed or Dutch auctions, where the bidding dynamics do not emphasize open competition.
