CBOT Trading Time: What Every Grain Trader Should Know Before the Next Session

The clock on your desk reads 6:58 p.m. Central Time. You’ve been watching the corn market drift sideways all afternoon, and now you’re waiting for the overnight session to open. A few minutes later, the quotes flicker to life. The CBOT market open time has arrived, and the rhythm of the grain markets begins again.

For traders who follow agricultural futures, understanding CBOT trading time is not a minor detail—it shapes when you watch, when you act, and when you step away. The Chicago Board of Trade, now part of CME Group, operates on a schedule that spans nearly the entire day, with a brief pause that catches some traders off guard.

The Two Sessions That Define the CBOT Trading Day

CBOT grain and oilseed futures trade in two distinct sessions each day, both measured in Central Time (CT), the exchange’s home time zone.

The first is the overnight electronic session, which runs from 7:00 p.m. to 7:45 a.m. CT, Sunday through Friday . This session opens the trading week on Sunday evening and carries through each weekday morning. For traders in Asia or Europe, this window is often the most convenient time to engage with CBOT markets.

The second is the daytime session, running from 8:30 a.m. to 1:20 p.m. CT, Monday through Friday . A 45-minute break separates the two sessions—from 7:45 a.m. to 8:30 a.m. CT—during which the market is closed for order entry, though pending orders are typically held until the reopen .

This dual-session structure means the CBOT market hours effectively cover 22 hours each trading day, with only a short pause in the morning. For products like corn, soybeans, wheat, and soybean meal, the schedule is consistent and predictable.

What Happens at the CBOT Market Close Time

The phrase “CBOT market close time” can refer to two different moments depending on context.

The daily settlement for most grain futures occurs at 1:15 p.m. CT, five minutes before the official close of the daytime session at 1:20 p.m. . This is when the exchange calculates the settlement price used for margin and clearing purposes. The final trades of the day may still execute until 1:20 p.m., but the settlement benchmark is already set.

There is also the trading halt between sessions. At 7:45 a.m. CT, the overnight session ends. Trading does not resume until 8:30 a.m. CT. This 45-minute gap is the only scheduled pause during the trading week .

Traders who hold positions overnight should note that the CBOT market close time on Friday is 1:20 p.m. CT. The market then remains closed until Sunday at 7:00 p.m. CT. During holidays, the schedule often shifts, and CME Group publishes adjusted hours in advance.

Why Time Zones Matter for CBOT Opening Hours

For international traders, the CBOT opening hours in Central Time translate to very different local clocks.

In Hong Kong time (HKT), during U.S. daylight saving (summer), the CBOT grain session runs from 8:00 a.m. to 8:45 p.m. HKT, then resumes from 9:30 p.m. to 2:20 a.m. HKT . During winter, everything shifts one hour later. For traders in London, the daytime session overlaps with the afternoon and early evening, while the overnight session begins late in the European evening.

This time-zone spread is precisely why the CBOT market hours are structured as they are: to give global participants multiple windows to access liquidity. A trader in Shanghai can watch the overnight session in the morning, while a trader in Chicago watches the same session in the evening.

The Challenge of Monitoring Markets Across Sessions

The practical difficulty for many traders is not knowing the schedule—it’s staying connected to it without being tethered to a trading terminal.

Consider a typical scenario. You have open positions in corn or soybeans. The daytime session ends at 1:20 p.m. CT. You step away from your desk. The overnight session opens at 7:00 p.m. CT. If you want to check how your positions are doing during that gap—or shortly after the reopen—you need to launch MetaTrader, log in, navigate to your positions, and watch the quotes update.

For traders who are also doing other things—working a day job, managing a household, or simply not wanting to stare at charts all day—this friction is real. The market is open for 22 hours, but you are not.

A Lighter Way to Stay in Touch with the Market

This is where a tool like Camovia Tray fits into the picture for MT5/MT4 users.

Camovia Tray turns MetaTrader 5 or MetaTrader 4 into a system tray utility. Instead of opening the full terminal every time you want a quick update, you hover over the tray icon and see your watchlist quotes in real time. The positions view shows open trades—symbol, direction, lot size, entry price, and current P&L—without launching the main window.

For someone tracking CBOT grain positions across the overnight and daytime sessions, this means you can check your exposure at 7:05 p.m. CT just after the reopen, or glance at your P&L at 1:25 p.m. CT after the close, without the full weight of a desktop terminal. If you decide to close a position, a two-step confirmation handles it directly from the floating window. On MT4, AutoTrading needs to be enabled for this to work; MT5 connects directly without an EA.

The data stays on your computer. Quotes and positions are read from your local terminal—nothing is uploaded. For traders who value privacy as much as convenience, that matters.

Keeping the Schedule Without Being Owned by It

The CBOT trading calendar is well-defined. The overnight session opens at 7:00 p.m. CT. The daytime session runs 8:30 a.m. to 1:20 p.m. CT. The brief halt between them is the only scheduled interruption. Knowing these times is the first step.

The second step is deciding how you want to relate to them. You can open MetaTrader every time you want a quote. Or you can keep the market a hover away, without letting it take over your screen or your attention.
