Roll. The industry roll date is eight calendar days before expiration (the Thursday of the prior week). Volume and open interest shift to the next quarter around this date.
First notice day. None – ES is cash-settled, so there is no delivery process and no first notice day. Longs can hold into expiration.
Last trading day. Third Friday of the contract month. If the exchange is closed that day, trading ends on the preceding business day.
US exchange holidays ahead: Nov 26 · Dec 25 · Jan 1 · Jan 18 · Feb 15 · Mar 26 · May 31 · Jun 18
Calculated from exchange rules and the US exchange holiday calendar. Confirm with the CME expiration calendar.

Before commissions and exchange fees. Prices round to the nearest tick of 0.25.
One tick is 0.25 index points, worth $12.50 per contract. A full index point is worth $50. On the Micro E-mini (MES) the same tick is worth $1.25.
Traders roll about eight days before expiration – on the Thursday of the week before the third Friday of March, June, September and December. After that date most volume trades in the next quarterly contract.
No. ES is cash-settled against the Special Opening Quotation of the S&P 500, so there is no delivery and no first notice day.
ES trades on CME Globex Sunday to Friday from 6:00 p.m. to 5:00 p.m. ET (5:00 p.m. to 4:00 p.m. CT), with a one-hour maintenance break each day at 5:00 p.m. ET.
The COT Index places a group's current net position within its own range over a lookback window: 100 = the most net long in that window, 0 = the most net short. It measures positioning extremes, not timing.
