CME Market Hours on Memorial Day: A Trader’s Guide to the Modified Holiday Schedule

It’s the Friday before Memorial Day weekend. You’ve got a short position in E-mini S&P 500 futures that you’re comfortable holding over the long weekend. Sunday night rolls around, and you see the Globex session open right on schedule at 5:00 PM CT. Everything looks normal. Then Monday morning arrives, and somewhere around midday, the market just… stops. If you didn’t know the holiday schedule, that pause might feel like a glitch. It isn’t.

Memorial Day is one of those U.S. holidays where CME futures don’t simply shut down for the entire day. Instead, they operate on a modified schedule that can catch unprepared traders off guard. Understanding how CME market hours work on Memorial Day is essential if you’re holding positions through the long weekend—or if you’re planning to trade the reopen.

What Actually Happens on Memorial Day

The common misconception is that U.S. futures markets are closed on Memorial Day. That’s not quite right. Most CME Group products, including equity index and interest rate futures, follow a specific pattern that differs from a full closure.

Here’s how it typically plays out, using Central Time (CT) as the reference:

Sunday evening: CME Globex opens as usual at 5:00 PM CT. This session carries Monday’s trade date, so it’s not an early start—it’s the normal beginning of the trading day.

Monday (Memorial Day): Trading halts at approximately 12:00 PM CT for most equity index and interest rate futures. This is an “early halt,” not a full-day closure.

Monday evening: The market reopens at 5:00 PM CT, this time for Tuesday’s trade date. From that point forward, the regular schedule resumes.

So what you get is a shortened Monday session sandwiched between two normal opens. The gap between noon and 5:00 PM CT creates a window where no price discovery happens. For traders with open positions, that gap can feel longer than five hours.

Why the Schedule Feels Confusing (And Why It Matters)

The Memorial Day schedule creates a peculiar situation: the market is open Sunday night, closed for part of Monday, and open again Monday night. If you’re not watching the clock, you might assume the holiday means a full day off. But the CME futures trading hours on Sunday before Memorial Day are completely normal—the holiday adjustment only kicks in once Monday’s session is underway.

This pattern repeats across most Monday U.S. holidays. The CME futures trading hours on Labor Day follow the same logic: Sunday open, midday halt, evening reopen. The CME futures trading hours on Thanksgiving are different—Thanksgiving falls on a Thursday, and the schedule involves an early close on Wednesday, a full halt on Thursday, and a shortened Friday session. Memorial Day and Labor Day share the Monday-holiday rhythm; Thanksgiving and Christmas follow their own rules.

The practical problem is that these schedules aren’t always intuitive. If you’re managing positions manually through a desktop terminal, you need to be at your computer to check the clock, verify the halt time, and decide whether to adjust stops or close early. That’s easy when you’re at your desk. It’s less convenient when you’re traveling for the holiday weekend, away from your main setup, or simply trying to step back from the screen for a few hours.

Managing Positions When You’re Not Glued to the Terminal

This is where the workflow around holiday trading gets interesting. The CME futures trading hours today might be modified, but your need to monitor exposure doesn’t disappear just because the market takes a midday pause.

For traders who use MetaTrader 4 or MetaTrader 5 as their execution platform, there’s a middle ground between sitting in front of the full terminal and being completely disconnected. Camovia Tray is a utility that turns MT5 or MT4 into a system tray tool—it lets you hover over a tray icon to see live quotes and check open positions without opening the main application window. The data stays on your computer, read directly from the local terminal.

During a holiday session like Memorial Day, this matters in a specific way. You might want to confirm that your E-mini position is still showing the expected P&L before the midday halt. Or you might want to glance at the market when it reopens at 5:00 PM CT without firing up the full terminal and rearranging your workspace. The tray-based approach keeps the essential information accessible while letting you stay in whatever else you’re doing—whether that’s a holiday barbecue or simply a quieter screen setup.

The Bottom Line for Memorial Day Planning

The key takeaway is straightforward: don’t assume Memorial Day means a full market closure. For most CME products, it’s a modified session with a midday halt and an evening reopen. Check the specific product schedule, note the halt time in your time zone, and decide in advance how you want to handle any open positions during the gap.

If you’re trading from a desktop terminal, that’s manageable. If you want the option to stay lightly connected—checking quotes and positions without the full terminal taking over your screen—tools like Camovia Tray are built for exactly this kind of situation: quick, local, tray-based access to MT4/MT5 data when you don’t need the whole platform running.
