When is the margin released from my expiring Bitcoin Future?

For the ETH, MBT or BRR future contract that stops trading Friday and is settled Monday, margin is not released until after the final settlement price is disseminated by the CME and the expiring contract is removed from the account, which is Monday evening during the regular overnight clearing session. The settlement dates for cryptocurrency Futures on the CME can be found on the CME website by selecting ETH Future Contract Specs, MBT future Contract Specs, or BRR future Contract Specs, then clicking on the Calendar tab.
