What Are CME Opening Times? A Trader’s Guide to Globex Hours and Holiday Schedules

If you trade futures on the Chicago Mercantile Exchange (CME), you already know the market never truly sleeps. But that doesn’t mean it’s always open. The CME Globex platform runs on a schedule that’s both predictable and occasionally confusing—especially when holidays like Labor Day, Thanksgiving, or even a random Sunday roll around. So let’s break down exactly when the CME opens, closes, and how to keep an eye on your positions without being glued to your terminal.

The Regular CME Globex Opening Time

The standard CME Globex session begins at 5:00 p.m. Central Time (CT) on Sunday and runs continuously until 4:00 p.m. CT on Friday. That’s the core rhythm: a Sunday evening open that kicks off the trading week, followed by a daily maintenance break from 4:00 p.m. to 5:00 p.m. CT.

In Eastern Time, that translates to a 6:00 p.m. ET Sunday open and a 5:00 p.m. ET Friday close. Most traders watching from the U.S. or Europe will see the week’s first quotes hit their screens on Sunday evening—right when many people are wrapping up the weekend.

The important nuance: when CME opens on Sunday, that session actually belongs to Monday’s trade date. So if you see markets moving at 5:00 p.m. CT on a Sunday, you’re already trading Monday.

What About CME Futures Trading Hours Today?

If you’re checking “CME futures trading hours today,” the answer depends on whether it’s a regular weekday or a holiday. During a normal Monday through Thursday, the market runs around the clock except for that daily 4:00–5:00 p.m. CT maintenance window. On Friday, the close comes earlier: 4:00 p.m. CT.

But here’s where it gets interesting. Many traders assume that a U.S. market holiday means CME Globex is shut down entirely. That’s simply not the case. Take CME futures trading hours on Labor Day as an example. The market actually opens as usual on Sunday evening at 5:00 p.m. CT—because that open belongs to Monday’s trade date, holiday or not. Then, on Monday itself, trading halts early, typically around 12:00 p.m. CT for major equity index contracts like the E-mini S&P 500. The market then reopens that same evening at 5:00 p.m. CT for Tuesday’s trade date.

So if you’re planning around CME futures trading hours on Labor Day, don’t expect a full day off. Expect a shortened afternoon session and a normal evening restart.

Thanksgiving and the Sunday Open: What Changes

CME futures trading hours on Thanksgiving follow a similar “early close” pattern, but with a twist. On Thanksgiving Thursday, most markets halt trading at 12:00 p.m. CT, then reopen at 5:00 p.m. CT the same evening for Friday’s trade date. Friday itself sees an early close, often around 12:15 p.m. CT for equity products.

And what about CME futures trading hours on Sunday during a holiday week? The Sunday evening open stays remarkably consistent. Even before a Monday holiday, Globex opens at 5:00 p.m. CT as usual. The difference is what happens during the holiday itself—not whether the Sunday session happens at all.

This pattern catches traders off guard every year. You might close out positions on Friday assuming the market is “closed” for Labor Day, only to see Sunday evening quotes rolling in. Or you might stay up late Sunday expecting a normal session, then forget that Monday’s halt is coming at noon.

Why the Schedule Matters More Than You Think

For anyone holding positions through a holiday, the early halt creates a real risk window. If you’re not watching when the market pauses at midday, you’re flying blind until the evening reopen. The CME schedules are published in advance, but keeping track of every product’s specific halt time—energy, metals, grains, and equities all differ—is a logistical headache.

This is exactly the kind of gap where Camovia Tray becomes useful. Instead of keeping a full MetaTrader terminal open on your desktop all day just to check whether the market has halted or what your position is doing, you can hover over a tray icon and see your open positions and live quotes instantly. The data comes directly from your local MT5 or MT4 terminal—nothing gets uploaded anywhere. So during a holiday session like Labor Day or Thanksgiving, when you need a quick glance to confirm whether the halt has kicked in or your position is still moving, you don’t have to disrupt your entire workflow to find out.

The Sunday Open and the “Today” Question

One of the most common search queries is simply “CME futures trading hours today.” The honest answer is: check whether it’s a holiday. On a normal weekday, you’re looking at 24-hour trading with a one-hour maintenance break at 4:00 p.m. CT. On a Monday holiday, you’re looking at a Sunday evening open, a midday halt, and an evening reopen. On Thanksgiving or Christmas, the pattern shifts again.

The CME Globex platform runs on Central Time, which adds another layer of confusion for international traders. A 5:00 p.m. CT open is 6:00 p.m. ET, 11:00 p.m. London, or 7:00 a.m. Tokyo the next morning. Getting the timezone conversion wrong means missing the open entirely.

A Practical Takeaway

CME opening times aren’t complicated once you internalize the core rhythm: Sunday 5:00 p.m. CT to Friday 4:00 p.m. CT, with daily breaks and holiday adjustments. But the holiday nuances—especially around Labor Day and Thanksgiving—are where traders lose track. The Sunday session before a Monday holiday opens normally; the holiday itself halts early and reopens that evening.

If you’re managing positions through these windows, the last thing you want is to be tethered to a full trading terminal just to check a price or close a position. Tools like Camovia Tray exist for exactly this reason: to let you see quotes and manage positions from the system tray, with data that stays on your machine. During a shortened holiday session, that kind of quick, low-friction access makes it easier to stay aware without staying glued to your screen.
