What Time Does CME Open on Sunday? A Trader’s Guide to Globex Hours and Holiday Schedules

If you trade futures, you already know the frustration: you spend the weekend waiting, watching the clock, and wondering exactly when the CME Globex session kicks back into gear. Some traders assume the market stays closed until Monday morning. Others think Sunday is a complete blackout. Neither is true. The reality is more specific—and knowing the precise answer can mean the difference between being ready at the open or missing the first move.

The Short Answer: It Depends on What You’re Trading

For most CME Group futures products, including the E-mini S&P 500 and other equity index contracts, the Globex session opens at 6:00 p.m. Eastern Time (5:00 p.m. Central) on Sunday and runs continuously until 5:00 p.m. ET on Friday. There is a daily maintenance period from 5:00 p.m. to 6:00 p.m. ET each afternoon, but the Sunday evening open is the true start of the trading week for the vast majority of CME futures.

That means when you search for “cme futures trading hours sunday,” the answer is almost always 6:00 p.m. ET—unless a holiday is involved.

Why Sunday Evening Matters More Than You Think

The Sunday open isn’t just a technical detail. It’s often when the market reacts to weekend news, geopolitical developments, and overnight moves in related markets. For traders who focus on equity index futures, being aware of the Sunday open is the first step toward planning the week.

But here’s where it gets tricky: not every Sunday is a normal Sunday.

When Holidays Shift the Schedule

Labor Day Weekend

Consider “cme futures trading hours labor day.” A common mistake is assuming that because Monday is a holiday, Sunday trading is canceled too. It isn’t. On the Sunday before Labor Day, Globex opens at its regular time—6:00 p.m. ET. The session is still considered Monday’s trade date.

What changes is what happens later. On Labor Day itself, CME Globex typically halts trading early, often around 12:00 p.m. CT for heavily traded equity contracts, and then reopens that same evening at 5:00 p.m. CT for Tuesday’s trade date. So the Sunday open happens as usual—the holiday affects Monday’s daytime hours, not Sunday night.

Thanksgiving

Thanksgiving follows a different pattern. There is no Sunday open involved, but “cme futures trading hours thanksgiving” is still a frequent search because the holiday falls on a Thursday. For 2026, CME Globex observes Thanksgiving on Thursday, November 26, with an early halt at 12:00 p.m. CT. Trading resumes that evening for the next trade date, and the following Friday (November 27) typically sees early closes across many product groups.

If you’re looking for the Sunday open around Thanksgiving, the relevant Sunday is the one before or after the holiday—and both follow the standard 5:00 p.m. CT schedule unless otherwise noted.

A Word on “CME Futures Trading Hours Today”

Searching “cme futures trading hours today” is a habit for many traders, but it’s also a trap. CME’s holiday schedules are often finalized only about two weeks before each holiday, and product-specific hours can vary. Equity index futures, energy, metals, and agricultural contracts don’t always share the same halt times on holiday-adjacent days.

The most reliable approach is to check the official CME trading hours page for your specific product. But if you trade multiple instruments or simply want a quicker way to stay oriented, there’s a practical solution that doesn’t require keeping a browser tab open all weekend.

Keeping an Eye on the Market Without Keeping the Terminal Open

The Sunday open often arrives when you’re not at your desk. Maybe you’re watching a game, having dinner, or just trying to enjoy the last hours of the weekend. Firing up MetaTrader, waiting for it to connect, and navigating to your watchlist feels like a lot of work just to check a few prices.

This is where a tool like Camovia Tray fits naturally into the workflow. It turns MT4 or MT5 into a tray utility: hover over the icon, and you see live quotes for your watchlist. You can view open positions and close them with a click—two-step confirmation included. All the data stays on your local machine; nothing is uploaded. For a trader who wants to know whether the Sunday open is behaving normally without committing to a full terminal session, it’s a lighter way to stay informed.

The tool also supports tray icon disguise and a privacy lock, which is useful if you share your screen or simply prefer not to advertise that you’re monitoring markets. It’s not about hiding from anyone—it’s about keeping your trading activity separate from the rest of your desktop.

The Bottom Line

For most of the year, the answer to “what time does CME open on Sunday” is 6:00 p.m. ET. Labor Day and other Monday holidays don’t change the Sunday open itself—they change Monday’s daytime session. Thanksgiving follows its own Thursday pattern, with the Sunday schedules on either side remaining standard.

The real challenge isn’t memorizing these times. It’s staying aware of them when the market moves and you’re away from your desk. Whether you rely on calendar reminders, official CME pages, or a tray tool that keeps quotes a hover away, the goal is the same: know when the market opens, and be ready when it does.
