CME Crude Oil Trading Hours: Full Schedule & Daily Breaks

Navigating the global energy markets requires a precise understanding of when liquidity is available and when the exchange officially pauses. For participants trading West Texas Intermediate (WTI) futures, mastering the CME crude oil trading hours is critical for managing margin requirements, executing complex spreads, and avoiding forced liquidations. This guide breaks down the complete electronic schedule, detailing the impact of daily maintenance windows, holiday adjustments, and how the CME timeline aligns with other major international benchmarks.

What Are the CME Crude Oil Trading Hours Right Now?

CME crude oil futures trade electronically 23 hours a day, six days a week on the CME Globex platform. Listed under the NYMEX exchange, the market opens on Sunday evening to capture the start of the Asian trading week and closes on Friday afternoon at the end of the U.S. session.

Regular Electronic Trading Hours (Sunday–Friday)

The regular trading week opens on Sunday at 6:00 p.m. Eastern Time (ET) and runs continuously until Friday at 5:00 p.m. ET, paused only by a brief daily halt. Trading operates on a T+1 schedule, meaning a trading session for the next calendar day officially begins at 6:00 p.m. ET the night before.

While electronic trading continues until the 5:00 p.m. ET close, the designated daily settlement price is determined earlier at 2:30 p.m. ET. This settlement figure is calculated using the volume-weighted average price (VWAP) of trades executed between 2:28 p.m. and 2:30 p.m. ET. Institutions and brokers use this 2:30 p.m. settlement—not the 5:00 p.m. final trade—for daily mark-to-market account valuations and margin calculations.

When Does the Daily Maintenance Break Happen?

The CME Globex exchange halts crude oil trading for 60 minutes every day from 5:00 p.m. to 6:00 p.m. ET (4:00 p.m. to 5:00 p.m. Central Time), Monday through Thursday.

This maintenance period acts as the hard boundary between daily trading sessions. During this hour, the matching engine goes offline. Resting orders remain in the electronic book, but no execution occurs, and traders cannot enter new market or limit orders until the system reopens.

For short-term speculators, this break dictates intra-day margin requirements. Most retail brokerages and proprietary trading firms (such as Topstep) require traders utilizing reduced day-trading margins to flatten all open crude oil positions 10 to 15 minutes prior to the 5:00 p.m. ET halt. Holding a position into the maintenance break typically triggers a margin violation, forcing the account into higher overnight margin requirements or resulting in auto-liquidation.

Are CME Crude Oil Hours the Same for Standard, E-mini, and Micro WTI Futures?

Yes, all three tiers of NYMEX WTI crude oil futures operate on the exact same Globex electronic schedule.

This synchronization prevents pricing discrepancies and maintains tight arbitrage opportunities across contract sizes during off-hours. A trader hedging a standard contract with micro contracts will not face liquidity lockouts on one leg of the trade.

While the CME futures trading hours are identical across these products, overnight liquidity varies significantly. The standard CL contract maintains deep, continuous liquidity throughout the Asian and European sessions. The Micro (MCL) and E-mini (QM) contracts experience wider bid-ask spreads and lower volume during these off-peak hours, increasing slippage risk for limit orders placed outside the core U.S. morning session.

How Do U.S. Holidays Affect the CME Crude Oil Schedule?

Beyond the regular weekly schedule, traders must also account for trading adjustments during U.S. holidays. U.S. federal holidays disrupt standard CME crude oil trading hours by triggering either complete session closures or abbreviated trading days. Because NYMEX WTI Crude Oil (CL) relies on the nearly 24-hour Globex electronic system, holiday schedules rarely result in full 24-hour blackouts; instead, the exchange implements staggered intra-day halts.

Which Holidays Cause Early Closes or Full Closures?

Good Friday and Christmas Day typically force full market closures, while holidays like Thanksgiving, Labor Day, and Presidents' Day result in early halts. A common trap for new traders is assuming crude oil follows the equity index schedule. While equity futures (like the E-mini S&P 500) generally halt at 1:00 p.m. ET on partial holidays, NYMEX energy products typically remain open until 2:30 p.m. ET.

During a standard Monday holiday, the Globex system opens at its normal Sunday evening time (6:00 p.m. ET) to initiate the Monday trade date. Electronic trading then halts midday on Monday, resuming that evening at 6:00 p.m. ET to begin the Tuesday session.

Note: When fixed-date holidays (like Independence Day or Christmas) fall on a weekend, CME applies observed date logic, typically shifting the trading disruption to the adjacent Friday or Monday.

Where Can You Check the Official CME Holiday Calendar?

Traders must use the official CME Group Holiday Calendar page to verify exact session times, as early halt schedules can shift based on liquidity conditions or clearing firm requirements. Third-party websites often incorrectly list Globex equity hours for energy products, leading to miscalculated entry and exit times.

To find the exact hours for your specific contract, follow these steps:

1. Navigate to the CME Holiday and Trading Hours page: This is the definitive clearinghouse for Globex, ClearPort, and Trading Floor schedules.
2. Filter by Exchange: Select "NYMEX" rather than CME or CBOT, as WTI Crude Oil (CL) and Micro WTI (MCL) operate strictly under NYMEX rules.
3. Select the Asset Class: Filter by "Energy" to isolate crude oil, natural gas, and refined products from the broader commodity complex.
4. Check the Status Column: Review the specific holiday date for "Preopen," "Open," or "Paused" statuses to confirm exact matching engine availability.

Relying on this official tool prevents forced liquidations by retail brokerages, which typically require margin requirements to be met 15 to 30 minutes prior to any scheduled holiday early close.

What Do the Daily Breaks and Session Resets Mean for Your Trades?

Just as holidays alter the broader calendar, routine daily maintenance pauses dictate how individual trades and margins are managed. The daily 60-minute break from 4:00 PM to 5:00 PM Central Time (CT) dictates when day orders expire, when daily margin requirements are calculated, and when the electronic matching engine pauses. Managing positions over this hour requires exact accounting, as the physical calendar date and the official exchange trade date diverge immediately after the pause.

How Does the Maintenance Window Affect Open Orders?

The status of an unfilled order during the 4:00 PM to 5:00 PM CT maintenance window depends strictly on its time-in-force designation. During this hour, the CME Globex matching engine halts continuous trading, and existing orders are processed according to their specific states.

• Day Orders (GFD): Standard "Good for Day" orders automatically expire at exactly 4:00 PM CT. To achieve the same execution in the next session, you must manually submit a new order.
• Good 'Til Canceled (GTC) Orders: These remain active in the central limit order book through the pause. However, they carry gap risk if the market opens at 5:00 PM CT at a price significantly different from the 4:00 PM CT close.
• Stop-Loss Orders: Pending stop and stop-limit orders designated as GTC carry over to the next session. Because they cannot be triggered during the maintenance hour, sudden macroeconomic news released during the break could cause the market to gap past your stop price upon reopening.
• Pre-Open Modifications: While continuous matching halts for the full 60 minutes, CME Globex enters a "Pre-Open" state from 4:45 PM to 5:00 PM CT Monday through Thursday (and 4:00 PM to 5:00 PM CT on Sundays). During this window, traders can place, modify, or cancel orders to queue them for the 5:00 PM CT open, but no actual trades will execute.

When Does the New Trading Day Officially Begin on CME?

The official CME trading day for crude oil futures (CL) begins at 5:00 PM CT, a full seven hours before the calendar date changes. This structure means the trade date and the calendar date rarely align for evening and overnight participants.

For example, a crude oil contract purchased at 6:30 PM CT on Tuesday is officially recorded on Wednesday’s trade date. This offset directly dictates end-of-day P&L calculations, margin call timelines, and daily candlestick charting aggregations. Because the daily settlement price is locked in prior to the 4:00 PM CT break (calculated based on volume-weighted trading between 1:28 PM and 1:30 PM CT for crude oil, even though electronic trading continues), any position initiated after 5:00 PM CT is immediately subjected to the next calendar day's market cycle and margin requirements.

How Do CME Crude Oil Hours Compare to Other Major Oil Markets?

While these daily rhythms govern WTI contracts on the CME, the schedule differs slightly across other global benchmark exchanges. CME Group operates its West Texas Intermediate (WTI) crude oil contract almost continuously, but its schedule slightly trails the other major global benchmark, ICE Brent crude. While CME crude oil trading hours enforce a 60-minute daily break, ICE Brent requires a 120-minute daily pause. Asian benchmark contracts, such as the Shanghai International Energy Exchange (INE) crude, operate on heavily segmented, regional daytime schedules rather than continuous 24-hour loops.

The table below outlines the specific schedule differences between the three largest global crude oil futures markets.

\Shanghai INE hours are converted to Eastern Time for direct comparison; local trading occurs 9:00 a.m. to 3:00 p.m. Beijing Time.*

How Do CME Hours Overlap With ICE Brent Trading?

CME WTI and ICE Brent futures are simultaneously open for 21 hours each trading day, beginning at 8:00 p.m. ET and continuing until CME closes at 5:00 p.m. ET the following afternoon. This massive overlap is necessary for the continuous pricing of the global oil market and allows physical hedgers and speculators to execute the WTI/Brent intercommodity spread.

Because the two exchanges utilize staggered daily maintenance breaks, market participants must navigate two distinct windows where only one major benchmark is actively pricing:

• 5:00 p.m. to 6:00 p.m. ET (WTI Closed, Brent Open): CME halts WTI trading for daily settlement processing. ICE Brent continues to trade for another hour.
• 6:00 p.m. to 8:00 p.m. ET (WTI Open, Brent Closed): ICE halts Brent trading. CME reopens the WTI contract for the new trading session.

Traders managing cross-market exposure cannot offset positions across both exchanges during these three hours. Sudden geopolitical developments or crude oil market shocks during these asynchronous windows will trigger outsized volatility on the active exchange, resulting in pricing gaps on the closed exchange once it reopens.

Which Hours See the Highest Liquidity in Crude Oil Futures?

Peak liquidity for CME crude oil futures occurs between 8:00 a.m. and 1:30 p.m. ET. This specific window captures the simultaneous activity of North American and European institutional desks. Outside of this global overlap, volume thins predictably based on regional time zones.

Traders executing large orders categorize the daily CME schedule into four distinct liquidity phases:

• Global Overlap (8:00 a.m. – 1:30 p.m. ET): This period features the tightest bid-ask spreads (frequently remaining at the one-cent minimum tick). High-frequency trading firms and commercial hedgers are fully active, allowing for high-volume execution with minimal slippage.
• Regular Trading Hours / RTH (9:00 a.m. – 2:30 p.m. ET): Known as the legacy "pit session" hours, this window accounts for the vast majority of daily US domestic volume. Within this block, Wednesdays at 10:30 a.m. ET produce the week's most aggressive liquidity spikes due to the release of the EIA Weekly Petroleum Status Report.
• US Afternoon (2:30 p.m. – 5:00 p.m. ET): Volume drops precipitously after the European close and the end of legacy RTH. The market shifts primarily to algorithmic market making, and traders executing market orders during this window face higher risks of slippage.
• Asian Session (8:00 p.m. – 2:00 a.m. ET): The overnight hours see the lowest participation. While the market functions normally, the order book is materially thinner, and minor supply disruptions or geopolitical headlines from the Middle East can trigger disproportionate price swings before Western institutions come online.

FAQs about CME Crude Oil Trading Hours

What are the trading hours for crude oil futures?

CME WTI crude oil futures trade Sunday through Friday from 5:00 p.m. to 4:00 p.m. Central Time (CT). There is a one-hour daily maintenance break in trading from 4:00 p.m. to 5:00 p.m. CT.

What are the holiday trading hours for CME crude oil futures?

Holiday trading hours for CME crude oil futures vary depending on the specific U.S. holiday being observed. On partial holidays, such as the day after Thanksgiving, energy contracts often close early at 12:30 p.m. CT (1:30 p.m. ET). Traders should always consult the official CME Group Holiday Calendar for exact details on market halts and early closures.

Does crude oil trade 24 hours?

Crude oil trades nearly 24 hours a day during the business week, but not continuously. It operates 23 hours a day from Sunday evening to Friday afternoon, pausing for a one-hour daily break. The market is closed entirely over the weekend from Friday afternoon until it reopens on Sunday evening.

Does CME trade 24 hours?

Historically, most traditional CME markets operate 23 hours a day, five days a week, with a one-hour daily break and weekend closures. However, CME Group is launching 24/7 trading for its regulated cryptocurrency futures and options starting on May 29, 2026. This allows continuous trading for specific digital assets throughout the weekend, aside from a brief mandatory maintenance window.

Conclusion

Successfully trading WTI futures demands strict adherence to the CME's specific timeline, from peak overlap periods to the rigid daily maintenance halts. Missing a session cutoff or miscalculating a holiday closure can instantly expose accounts to margin violations and unexpected gap risk. By mapping out regular hours, daily resets, and global liquidity windows, traders can confidently sequence their entries and exits while safeguarding their capital against off-hours volatility.
