Does overtime count?
Yes. Overtime counts for all markets.
What happens if a game is cancelled?
If a game is cancelled, all markets resolve to the last fair price as determined by the Exchange.
EXCEPTION: Nadex (Predictions powered by UDM Services, LLC): If a game is postponed, cancelled, or otherwise not completed within 48 hours of its originally scheduled start with no winner decided, it is treated as Event Cancelled.
What happens if a game is abandoned mid-game?
If the game does not resume within 24 hours:
40+ minutes of gameplay completed: final score markets settle based on the score at that point.
Fewer than 40 minutes played: all markets resolve to the last fair price.
EXCEPTION: Nadex (Predictions powered by UDM Services, LLC): If the game is not completed within 48 hours of its originally scheduled start with no winner decided, it is treated as Event Cancelled — regardless of how much of the game was played.
What happens if a game is delayed?
Delayed two weeks or less: markets remain open.
Delayed more than two weeks: all markets resolve to the last fair price.
EXCEPTION: Nadex (Predictions powered by UDM Services, LLC): If the game is not completed within 48 hours of its originally scheduled start with no winner decided, it is treated as Event Cancelled.
What happens if my market is an Event Cancelled? (Nadex)
Your pick is paid out based on its recent market price, and your trading fees are refunded. (The payout uses the average price over the week before cancellation.)
