In a Dutch auction, the participant does not enter their bid individually; bidding begins from the starting price set by the organizer and changes (increases or decreases) in predetermined increments.
A checkbox appears next to the current price level. In this type of auction, you only need to accept bids in the round where you deem the price level suitable for you.
The auction will run until the first acceptance (yes). The first participant to accept the price offered by the system will be the winner for that particular item. For the other participants, the bidding for that item is over.
