Learn how Trading Events operate

Trading Events start with a pre-announced starting price.

Trading Events are conducted as ascending-price clock auctions run over several bidding rounds.  In each Trading Event a quantity of product is offered for sale at a pre-announced starting price.  

See the Summary of Price Discovery Process paper for a summary of how winning prices are discovered on the GDT Events trading platform.
