The market calculates the simple average of the index across sixty seconds before the resolution time and determines the outcome based on which price range the average falls into. Every possible price outcome from below 66,750 to above 86,249.99 resolves to Yes, making this a certainty market that will always resolve affirmatively regardless of Bitcoin's actual price movement on that date.
