RV observation windows
The 24-hour, seven-day and 30-day RV windows are assessed independently using observed one-minute index returns, annualised on a 365-day basis. Recorded minimums: at least 99.5% coverage over 24 hours, 99.5% coverage over seven days, 99.5% coverage over 30 days, with no gap longer than 60 minutes. Returns spanning gaps are excluded, not interpolated; unavailable windows remain unreported. The exact 24-hour spot return requires prices at both endpoints.
