Learn how Trading Events operate

GDT Events provide a mechanism for connecting buyers and sellers from around the world. It pulls product on sale and brings demand to bear on that supply, twice monthly.

By doing this, GDT Events discover what that fair market price is, and protects both parties to the transaction from getting it wrong.

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