Trading Information



On the day of expiration, the Exchange Delivery Settlement Price ('EDSP') is calculated as the time-weighted average of the Index between 07:30 UTC and 08:00 UTC.

During the expiration window, Thalex broadcasts:

  • Current Expiration Average: time-weighted average of the Index since the start of the expiration window, accompanied by a timestamp to track expiration progress.
  • Expected EDSP: average of the Current Expiration Average and the Index, weighted by time elapsed and time remaining relative to the expiration window.

An expiring future will have its Mark Price calculated based on the Expected EDSP.
