COMEX Opening Hours: A Complete Guide to COMEX Market Hours and Closing Time

If you trade gold, silver, copper, or other metals, you have probably asked yourself at some point: what time does COMEX actually open? Maybe you woke up early to check a position, or you stayed up late waiting for a price move, only to realize the market was in a maintenance break. Understanding COMEX opening hours is not just trivia—it directly affects when you can trade, when you can close a position, and when you should simply stay away.

What Are COMEX Opening Hours?

COMEX, the Commodity Exchange division of the CME Group, operates on the CME Globex electronic trading platform. Its regular schedule runs Sunday through Friday, from 6:00 PM to 5:00 PM Eastern Time, with a daily maintenance break from 5:00 PM to 6:00 PM ET. In other words, the COMEX market open time is effectively 6:00 PM ET on Sunday for the new trading week, and the electronic session resumes each day at 6:00 PM ET after the one-hour pause.

The exchange is closed on Saturdays and reopens Sunday evening. It also observes a set of U.S. holidays, during which trading hours are shortened or halted entirely.

Why the Open Time Feels Different for Indian Traders

For traders in India, the COMEX market open time in India depends on the U.S. daylight saving schedule. When U.S. daylight saving time is in effect (roughly March to November), the active U.S. metals session overlaps with Indian evening hours, and MCX’s evening session closes at 11:30 PM IST. When the U.S. returns to standard time, the overlap shifts later, and MCX’s closing extends to 11:55 PM IST.

The COMEX market hours most relevant for Indian participants—when gold, silver, and copper see their highest liquidity—typically fall between approximately 6:30 PM and midnight IST during U.S. daylight saving, and about 7:30 PM to 1:00 AM IST otherwise. That is when U.S. data, institutional activity, and price discovery converge.

The COMEX Market Closing Time Today (and Every Day)

So what about the COMEX market closing time today? During a regular trading day, the electronic session pauses at 5:00 PM ET for the maintenance window. The weekly close is also 5:00 PM ET on Friday. However, “closing time” can be misleading. The CME Globex platform trades nearly around the clock, so the market is rarely “closed” in the traditional sense except during the one-hour break and on weekends.

On holiday-shortened sessions, the closing time may come earlier. For example, on several U.S. holiday Mondays in 2026, CME Globex halts metals trading around 12:00 PM CT (1:00 PM ET) and reopens at 5:00 PM CT for the next trade date. Checking the CME holiday calendar before a U.S. public holiday is always wise.

What This Means for How You Watch the Market

The practical challenge with COMEX hours is not the schedule itself—it is the gap between when the market is active and when you are available to check it.

Consider a typical scenario: You hold a gold or silver position through the U.S. session, which for you runs into the late evening. The market moves while you are away from your desk. You want to know whether a position is still healthy, whether a price level has been breached, or whether you should close a trade before the daily break. Opening MetaTrader, navigating to the chart, and checking each position individually takes time—time that matters when the market is moving.

This is where Camovia Tray fits naturally. It turns your MT5 or MT4 into a system tray tool, letting you hover over the tray icon to see live quotes without opening the terminal. Your open positions—symbol, direction, lot size, entry price, and current P&L—are visible in the floating panel. If you decide to close a position during the active COMEX window before the maintenance break, you can do it with a two-step confirmation (click “Close,” then “Confirm”) directly from the tray. The data comes from your local terminal; nothing is uploaded. For a trader monitoring metals across time zones, that convenience is not a gimmick—it is a small but meaningful reduction in the friction between you and your positions.

A Quick Reference

If you trade metals with any regularity, knowing when COMEX opens and closes is the baseline. Knowing how to check your positions quickly—without disrupting your evening or losing track of a moving market—is the next step.
