COMEX Exchange Opening Time: A Complete Guide for Futures Traders

If you trade gold, silver, or copper futures, you have probably asked yourself: when does COMEX actually open? The answer is not as simple as a single timestamp. The COMEX exchange opening time depends on the product, the trading session, and whether you are looking at electronic or floor trading. Understanding these nuances can make the difference between catching a move and missing it entirely.

What Is COMEX and Why Do Its Hours Matter?

COMEX, short for Commodity Exchange Inc., is a division of the Chicago Mercantile Exchange (CME) Group and one of the world's largest futures exchanges for metals. It handles contracts for gold, silver, copper, aluminum, and other metals. Because metals like gold trade nearly around the clock, knowing the precise COMEX exchange hours is critical for anyone looking to enter or exit positions at the right moment.

Unlike stock markets that open and close at fixed times, COMEX operates on an electronic platform called CME Globex, which provides nearly continuous trading throughout the week. This means the COMEX exchange opening time for electronic trading differs significantly from traditional floor sessions.

COMEX Exchange Opening Time: Electronic Trading Schedule

The primary COMEX exchange opening time for electronic trading is Sunday at 5:00 PM Central Time (CT) . From that point, the market runs continuously until Friday at 4:00 PM CT, with a daily maintenance break from 4:00 PM to 5:00 PM CT .

In Eastern Time, this translates to a Sunday opening at 6:00 PM ET. The market then operates nearly 23 hours per day, pausing only for the daily maintenance window. For traders in other time zones, this means the COMEX exchange opening time aligns with the start of the Asian trading week, making it accessible to participants across the globe.

It is worth noting that the COMEX closing time each day is 5:00 PM ET, followed immediately by the one-hour break before reopening at 6:00 PM ET . This daily rhythm defines the COMEX futures trading hours for most metals contracts.

COMEX Futures Trading Hours by Product

While the general electronic schedule applies to most contracts, individual metals may have slightly different hours. Here is a quick breakdown:

The COMEX market close time for all three metals follows the same pattern: a daily pause from 5:00 PM to 6:00 PM ET, plus weekend closure from Friday 5:00 PM until Sunday 6:00 PM.

For traders who focus on precious metals, these COMEX futures trading hours provide ample opportunity to react to global events, from U.S. economic data releases to geopolitical developments in Asia and Europe.

Recent Changes to COMEX Trading Hours

In 2026, CME Group announced amendments to certain COMEX contracts that expand trading hours even further. For the 1-Ounce Gold Futures contract, effective July 24, 2026, trading hours were extended to nearly 24/7, with only brief maintenance windows on Saturday and weekdays.

This change reflects the growing demand for continuous access to metals markets. As the COMEX market close time becomes increasingly irrelevant for certain contracts, traders need reliable tools to monitor positions regardless of when they occur.

Why COMEX Exchange Hours Matter for Your Trading Strategy

Understanding the COMEX exchange opening time is not just academic. The hours when COMEX is active often coincide with the highest liquidity and volatility. For example:

• The U.S. session (8:20 AM–1:30 PM ET) overlaps with the release of major economic reports, often driving significant price movements.
• The Asian session (starting at 6:00 PM ET) captures demand from Chinese and Japanese markets, which are major consumers of copper and gold.
• The European session bridges the gap, with London serving as a key hub for precious metals trading.

Knowing the COMEX closing time helps traders avoid entering positions right before the daily break, when liquidity can dry up and spreads may widen.

Managing Positions When You Are Away from Your Terminal

Even with a clear understanding of COMEX exchange hours, life does not always allow you to sit in front of a trading terminal. Whether you are at work, in a meeting, or simply away from your desk, the need to check prices and manage positions can arise at any moment.

This is where a tool like Camovia Tray can make a practical difference. Camovia Tray transforms your MetaTrader 5 (MT5) or MetaTrader 4 (MT4) into a tray-based utility. Instead of opening your trading terminal and navigating through multiple screens, you can hover over the tray icon to see live quotes for your watchlist instruments, including gold and silver futures.

For traders who follow COMEX market close time and other key sessions, this quick-access approach means you can glance at prices without disrupting your workflow. If a position needs attention, you can view open positions directly from the floating window and close them with a two-step confirmation. The entire process happens without launching the full MT5/MT4 interface.

Perhaps most importantly, Camovia Tray keeps all quotes and position data on your local machine. The data is read directly from your terminal and never uploaded to external servers. For privacy-conscious traders who want to monitor COMEX futures trading hours without exposing their trading activity, this local-first design offers peace of mind.
