A more thorough explanation:

An auction market is a type of market where securities are bought and sold through competitive bidding by brokers. This means that buyers and sellers come together to bid on the price of a security until they reach an agreement. The New York Stock Exchange is an example of an auction market.

For example, if a buyer wants to purchase a share of a company's stock, they will place a bid for a certain price. If a seller is willing to sell their share for that price, the transaction will take place. The bidding process continues until all buyers and sellers have reached an agreement on the price.

Another example of an auction market is an art auction, where buyers bid on artwork until the highest bidder wins the piece.

Auction markets are different from negotiated markets, where buyers and sellers negotiate the price of a security directly with each other.
