Calculation Details
Equity Indices
Equity Index futures special fixing prices are used to determine whether corresponding weekly and end-of-month options positions are in the money at expiration. The prices are calculated on the VWAP of nearest expiring futures contracts traded in the 30-second window ending at 4:00 p.m. Eastern Time.
Calculation Details
On expiration days for end-of-month (EOM) and weekly options on E-mini S&P 500 futures, CME Group calculates a special fixing price based on the weighted average trading price of the nearest expiring month for the E-mini S&P 500 futures in the last 30 seconds (2:59:30 - 3:00:00 p.m.) of trading before the 3:00 p.m. (Central Time) options expiration. This calculation always uses the nearest contract until it is no longer available for trade.
The EEF is a fixing price based on a volume-weighted average price of the nearest expiry for the E-mini S&P 500 futures in the 30 seconds preceding 4:30 p.m. London time (4:29:30 p.m.-4:30:00 p.m.). This calculation always uses the nearest contract until it is no longer available for trade.
EJF calculation*
The EJF is a fixing price based on a volume-weighted average price of the nearest expiry for the E-mini S&P 500 futures in the 30 seconds preceding 3:30 p.m. Tokyo time (3:29:30 p.m. -3:30:00 p.m.). This calculation always uses the nearest contract until it is no longer available for trade.
On expiration days for weekly options on E-mini Nasdaq-100 futures, CME Group calculates a special fixing price based on the weighted average trading price of E-mini Nasdaq-100 futures in the last 30 seconds (2:59:30 p.m.- 3:00:00 p.m.) of trading before the 3:00 p.m. (Central Time) options expiration. This calculation always uses the nearest contract until it is no longer available for trade.
