Take the Decision Test →The E-mini S&P 500 (ES) futures contract trades on the CME Globex platform nearly around the clock on weekdays — from Sunday 6:00 PM ET through Friday 5:00 PM ET. But "open" doesn't mean "worth trading." Volume, volatility, and conviction shift dramatically through the day. The clock above tracks where you are in that cycle; the table below is the reference.
| Session | Time (ET) | Character |
|---|---|---|
| Asian session | 6:00 PM – 3:00 AM | Quiet, thin. Levels form; don't force trades. |
| London session | 3:00 AM – 8:00 AM | Volatility builds as Europe trades. |
| NY pre-market | 8:00 AM – 9:30 AM | Positioning into the open. Watch, don't chase. |
| NY open (RTH) | 9:30 AM – 11:00 AM | Highest volume. Prime reversal window. |
| Lunch lull | 11:00 AM – 1:30 PM | Chop, low conviction. Step away. |
| Power hour | 1:30 PM – 4:15 PM | Conviction returns into the close. |
| Post-close | 4:15 PM – 5:00 PM | Winding down. Thin and unreliable. |
| Maintenance break | 5:00 PM – 6:00 PM | Market halted. No trading. Day resets. |
Every weekday evening from 5:00 PM to 6:00 PM ET, CME Globex halts entirely — no new orders, no modifications, no cancellations. The platform marks positions to market and a new trading day begins at 6:00 PM ET. If you trade a funded account with rules requiring you to be flat, this is the deadline you plan around. Most session clocks ignore it. This one doesn't.
ES Regular Trading Hours run 9:30 AM to 4:15 PM ET, overlapping the U.S. cash equity market. Roughly 70% of daily ES volume happens in this window — which is why the open and the power hour, the bookends of RTH, are where conviction lives.
