Three auction clocks at FloraHolland in Bleiswijk.
An auction at discount or discount at auction is an auction where a product is used at an overpriced price, after which the price drops until someone agrees. The most famous place where this auction form is used is the Aalsmeer flower auction. Abroad, this form of auction is known as a Dutch Auction. History
This form of auction goes well back in time and mainly takes place with land and horticultural products and fish. In the past, this form of auction took place orally and the first trader was "mine!" (ie "mine!") was able to indicate which part of the lot was taken for that price. To avoid the problem of multiple merchants simultaneously "mine!" Call, the auction clock was entered. Process
In this way, flower auctions and fish fillets work in this way. The auction is as follows: the bidders are together and see the lot of the product being auctioned. For this party a price is set at the big clock. This price starts high after which the price drops (what can be seen on the clock). The bidder who first presses (formerly called "my") buys the party. The art is not to print too soon, because you pay too much, but if you get too late, another buyer has already bought the lot. When the price drops below a certain value, the clock will stop and no transaction will be established. It is said that the party has been "rotated". This serves as a minimum price. Sources
