When Does COMEX Trading Open? A Complete Guide to COMEX Market Hours

If you have ever woken up early to check the gold price, only to find the chart has barely moved, you have already brushed against the quiet rhythm of the COMEX market hours. The metal markets do not roar to life the moment you open your trading platform. They breathe with a global schedule, and understanding when that schedule begins is the first step toward trading with intention rather than reaction.

The COMEX market open time is not a single moment for all participants, because COMEX, a division of the Chicago Mercantile Exchange Group, operates on an electronic platform that spans nearly the entire week. For most traders watching metals futures, the practical answer is this: the COMEX market opens for electronic trading on Sunday evening at 5:00 p.m. Central Time (CT), which is 6:00 p.m. Eastern Time . That opening bell marks the start of a trading week that runs continuously until Friday afternoon, pausing only for a brief daily maintenance window.

But knowing the technical open is only half the picture. The more important question for anyone trading gold, silver, or copper is when the market actually becomes worth watching. The quiet Sunday open often sees thin volume and wide spreads. The real energy arrives when the COMEX market hours overlap with the active hours of the U.S. session, typically between 9:00 a.m. and 2:30 p.m. Eastern Time . This is when volume surges, liquidity deepens, and price discovery genuinely accelerates.

For traders in India, this creates a unique rhythm. The COMEX market open time in India does not align with the Indian workday morning at all. When the U.S. active session begins, it is already evening in India. During U.S. Daylight Saving Time, the most liquid window runs roughly from 6:30 p.m. to midnight IST . When the U.S. returns to Standard Time, that window shifts an hour later, stretching from about 7:30 p.m. to 1:00 a.m. IST . This is why MCX’s evening session is designed to overlap with the American hours: Indian traders are effectively trading the COMEX-driven price action without leaving their own exchange .

What about the end of the day? The COMEX market closing time today follows a similar logic. Electronic trading pauses daily from 4:00 p.m. to 5:00 p.m. CT for a maintenance period . The weekly close comes on Friday at 4:00 p.m. CT, after which the market rests until Sunday evening. Beyond that, specific contracts may have slightly different schedules, and holiday hours can shorten sessions or shift the daily maintenance window .

These hours matter because metal prices rarely move in isolation. A trader holding a gold position overnight watches the COMEX open to gauge whether the overnight drift will be confirmed or rejected. Someone managing silver exposure checks the COMEX market hours to know when to expect the most reliable liquidity. And for those who trade both MCX and international metals, the overlap between Indian evening hours and the American session is the window where opportunity is most concentrated.

That concentration of activity also creates a practical challenge. The hours that matter most often fall outside the hours when a trader is sitting at a desk. Gold might spike on a COMEX open while you are commuting. Silver might reverse on a U.S. data release while you are away from your terminal. The question becomes not just when COMEX opens, but how you stay connected to it without being chained to a screen.

This is where Camovia Tray fits naturally into the picture. It turns MT5 or MT4 into a system tray tool, letting you check live quotes from a tray icon hover and manage open positions without opening the full trading terminal. When the COMEX market open time arrives and you want to see how your metals positions are responding, a glance at the tray gives you the answer. If a position needs to be closed, the floating orders panel shows your open trades with entry price and current P&L, and a two-step confirmation lets you close directly from there. The data is read locally from your MT5 or MT4 terminal, so the quotes and position information stay on your computer.

The COMEX schedule is not something you can change, but you can decide how much of your attention it demands. Knowing when the market opens is useful. Knowing you can stay connected to it without keeping a chart window open all day is what makes those hours actually workable.
