S&P 15 min

Important Information: Intraday observations use the prior second's candle close for settlement. For example, the price at 12:00 PM ET uses the 11:59:59 AM ET timestamp value. A clarifying contract amendment will follow.

For the final 15-minute timeslot of the day (3:45–4:00 PM ET), this market settles using the S&P 500 value at the 3:59:59 PM ET timestamp, not the official end-of-day closing value.
