What Are CBOT Trading Hours? A Complete Guide to the Grain Market Schedule

If you trade agricultural commodities—corn, soybeans, wheat—you’ve probably asked yourself: when exactly does the CBOT open and close? Unlike the stock market’s tidy 9:30-to-4:00 window, the Chicago Board of Trade operates on a schedule that spans nearly the entire day, with a split session structure that can catch unprepared traders off guard. Understanding these hours isn’t just trivia; it directly affects when you can enter or exit positions, when volatility spikes, and how you structure your trading routine.

The CBOT Market Open Time and Overnight Session

The CBOT grain complex—including corn, soybeans, soybean meal, soybean oil, wheat, and oats—kicks off its electronic trading week on Sunday evening. The CBOT market open time for the overnight session is 7:00 p.m. Central Time (CT). This session runs continuously through the night, pausing at 7:45 a.m. CT the following morning.

That overnight window is where much of the action happens for traders monitoring global weather patterns and overseas demand. When news breaks in Asia or Europe during U.S. sleeping hours, the CBOT is already trading—giving you a chance to react before the day session even begins.

The Day Session and the Midday Pause

After the overnight halt at 7:45 a.m. CT, the market takes a brief break before reopening for the day session. The CBOT opening hours for daytime trade begin at 8:30 a.m. CT and run until 1:20 p.m. CT. This is the traditional, most liquid window—the period most associated with the CBOT market hours that floor traders once worked.

Between the overnight close and the day open, there’s a 45-minute gap. During this time, orders can accumulate, and price gaps sometimes form. When the day session resumes at 8:30, that pent-up activity can release quickly—something worth keeping in mind if you’re placing orders right at the open.

When Does the CBOT Market Close?

The CBOT market close time for the day session is 1:20 p.m. CT. After that, the grain markets enter a daily maintenance halt until 7:00 p.m. CT, when the cycle begins again for the next trade date. Unlike futures contracts that trade nearly around the clock, the grain complex has this built-in break—a pause that gives the market time to settle and participants time to step away.

For expiring contracts, there’s an earlier cutoff: trading in a contract on its final day closes at 12:00 p.m. CT. If you hold a position into expiration, that’s the deadline you need on your radar.

Why These Hours Matter for Your Trading Routine

The CBOT schedule creates a rhythm that’s both an opportunity and a challenge. The overnight session captures global developments; the day session concentrates liquidity into a few hours. For traders who also hold positions in MetaTrader 5 or MetaTrader 4, the gap between when the CBOT closes and when your terminal needs attention can feel like a lot of scattered monitoring.

That’s where a tool like Camovia Tray fits naturally into the picture. If you’re tracking CBOT grain positions alongside other instruments in MT5 or MT4, you don’t always need to keep the full terminal open on your desktop. Camovia Tray turns your MT5/MT4 into a tray tool—hover over the tray icon to see live quotes for your watchlist, and manage open positions (view them, close them) right from the tray menu. When the CBOT overnight session is moving and you just want a quick check without disrupting your workflow, that kind of lightweight access makes the schedule easier to live with.

The privacy angle matters too. All quote and position data stays on your computer—Camovia Tray reads directly from your local MT5/MT4 terminal. No data leaves your machine. For traders who prefer to keep their market activity private, that’s a meaningful detail, especially during those late-night or early-morning CBOT sessions when you might not want a full trading interface visible on screen.

A Quick Reference for the CBOT Trading Schedule

The CBOT opening hours and CBOT market close time define the two distinct windows where liquidity concentrates. The overnight session rewards traders who can monitor global news; the day session rewards those who can be present when volume peaks.

If your trading setup involves MT5 or MT4 and you’d rather not keep the terminal front-and-center through every CBOT session, Camovia Tray offers a way to stay connected—quotes on hover, positions at a glance, close orders with a couple of clicks—without the full workspace. It’s a small adjustment that can make the CBOT’s long, split schedule feel a little more manageable.
