What time does the forex market open? Track the 24-hour cycle across the 4 major trading sessions

Forex never sleeps, but knowing exactly what time does the forex market open is critical to your success. In this guide, I’ll walk you through forex market hours, explain session overlaps, and show how these details can make or break your strategy. If you’re ready to level up your trading, this is the knowledge foundation you can’t ignore.

1. What are the forex market hours? What time does the forex market open?

Through years of trading, I’ve learned that timing can turn an average trade into a great one. Unlike traditional stock exchanges, the forex market operates 24 hours a day, five days a week,  thanks to its global nature and decentralized structure.

The market opens on Sunday at 5 p.m. EST in New York and closes on Friday at 5 p.m. EST, giving traders worldwide the opportunity to trade at virtually any time during the workweek. 

However, this doesn’t mean it’s always active. Depending on which forex trading session you’re in, Sydney, Tokyo, London, or New York, market volatility, volume, and trading conditions vary.

Here’s how it works:

• Forex trading begins in Sydney, then moves through Tokyo, London, and finally New York.
• Each trading session spans approximately 9 hours, but as one ends, another begins, creating overlap periods where market activity is particularly high.
• This cycle creates a continuous loop of opportunities, though there’s a notable quiet period between 7 PM and 10 PM EST when New York winds down and Sydney hasn’t yet ramped up.

If you’re wondering what time does the forex market open on Sunday, the answer is 5 p.m. EST, but that’s 10 p.m. UTC, marking the start of the Sydney session.

2. Why can the forex market stay open 24 hours a day?

This around-the-clock nature of forex trading still surprises many newcomers. In my early days, I too was curious: How can a financial market never sleep?

The answer lies in technology and geography. Forex trading isn’t routed through a central exchange. Instead, it's conducted over-the-counter (OTC) via a network of banks, brokers, and financial institutions across different time zones.

As one major financial center closes, another opens. This global relay system keeps the forex market open 24 hours a day from Monday to Friday. According to the Bank for International Settlements (BIS), this structure fuels an average daily trading volume of $6.6 trillion, making forex the largest and most liquid market in the world.

More than 170 currencies are actively traded, with the USD, EUR, JPY, and GBP dominating the volume. To understand market dynamics and session overlaps, knowing what time does the forex market open in each region is key to spotting liquidity and volatility windows.

3. Why are the opening and closing hours of the forex market important for a trader’s success?

If there’s one thing I emphasize to traders I mentor, it’s this: timing your trades to match market activity can drastically improve your results.

Opening and closing hours are when volatility spikes, driven by news releases, institutional flows, and economic data. For example:

• Tokyo session: best suited for trading JPY pairs like USD/JPY or EUR/JPY.
• London session: offers strong momentum and is perfect for GBP/USD or EUR/USD.
• New York session: ideal for trading USD-crosses and catching late-day volatility.

Matching your strategy to these active hours can help you capture bigger moves, avoid slippage, and make more informed decisions. It’s also crucial if you’re a day trader or scalper, because these styles depend heavily on momentum and liquidity.

So next time you ask yourself at what time does the forex market open, don’t just look at the clock, look at your trading plan.

4. Opening times of the four major trading markets and the forex market session overlap

Not all trading hours are equal. Each forex session has unique characteristics, and understanding them helps refine your approach.

4.1. Major Forex Market Sessions

Here’s a breakdown of when each of the four major forex sessions open and close:

Note: These hours may shift slightly during Daylight Saving Time (DST) in the U.S., U.K., and Australia.

4.2. When do forex market sessions overlap?

Session overlaps create prime trading opportunities. These time windows are when two major sessions are open at once, resulting in increased trading volume and market volatility.

Understanding what time does the forex market open in each region helps traders identify these overlaps and capitalize on the most active hours. Here are the key overlap periods:

• London & New York: 1:00 PM – 4:00 PM GMT: Most active. High liquidity. Best for EUR/USD, GBP/USD.
• Sydney & Tokyo: 00:00 AM – 7:00 AM GMT: Quieter. Ideal for trading AUD/JPY or NZD/JPY.
• London & Tokyo: 8:00 AM – 9:00 AM GMT: Short overlap. Low volatility.

In my experience, the London–New York overlap is the golden hour for trading. During this period, I’ve consistently seen tighter spreads, faster executions, and explosive market moves.

5. Be aware of key factors when exploring what time does the forex market open

Understanding what time the forex market opens goes beyond looking at the clock. There are dynamic variables, such as daylight saving time and global holidays, that subtly shift the landscape of forex market hours, and these changes can either enhance or undermine your trading results if you're not paying attention.

5.1. Daylight Saving Time (DST)

One often-overlooked factor is daylight saving time (DST), which temporarily shifts the schedule of global forex trading sessions, particularly in countries like the United States, the United Kingdom, and Australia. If you're not tracking these seasonal changes, you may find yourself entering trades during thin liquidity hours or missing key overlaps between sessions.

During November to March (Winter), for example:

• Sydney session runs from 10:00 PM to 8:00 AM GMT (9:00 AM to 7:00 PM local time).
• Tokyo session runs from 11:00 PM to 9:00 AM GMT (8:00 AM to 6:00 PM local time). (Note: Tokyo is not affected by DST.)
• London session shifts to 7:00 AM to 5:00 PM GMT.
• New York session adjusts to 12:00 PM to 10:00 PM GMT.

I’ve personally seen traders miscalculate pip movements simply because they didn’t account for this shift. That’s why, in my own routine, I always double-check session openings using a time converter tool or set alerts through a trusted forex calendar app. Accurately tracking what time does the forex market open during different seasons, especially around Daylight Saving Time, can prevent costly timing errors.

Beyond the major sessions, keep an eye on minor markets too, such as New Zealand, Frankfurt, Hong Kong, and Singapore, especially if you're working with cross pairs or exotic currencies.

5.2. Holidays that affect the forex market hours

Public holidays are another factor that can quietly disrupt your trades. While the forex market is open 24/5, it does fully close on Christmas Day and New Year’s Day.

Other holidays like Japanese Golden Week or U.S. Thanksgiving may not shut down the market but can dramatically reduce liquidity and volatility, particularly in specific currency pairs. For example, trading the JPY during Japanese bank holidays can lead to sudden drops in volume and irregular price behavior.

To stay updated, I personally follow economic calendars from platforms like Forex Factory or Investing.com. These tools highlight global events and help identify low-volume days that can affect your spreads, slippage, and risk exposure.

6. What time does the forex market open for the best forex trading opportunities?

After years of tracking forex market hours, I’ve learned one truth: overlaps = opportunity.

The best time to trade forex is when two major sessions are active simultaneously, increasing volume and volatility. Knowing what time does the forex market open in each region helps traders align their strategies with these overlapping sessions for maximum impact.

The London–New York overlap, from 1:00 PM to 5:00 PM GMT, is widely regarded as the most liquid period. During this window, popular pairs like EUR/USD and GBP/USD show tighter spreads and more predictable price movements.

Here’s why:

• Increased volume means more participants and better pricing efficiency.
• Brokers often offer tighter spreads thanks to higher trade flow.
• Institutional traders also prefer this window to act on news or economic data.

In contrast, when only one session is active, say, Tokyo before London, price movement tends to be narrower, which may not suit momentum strategies. That’s why knowing when and where the forex market opens helps align your trading style to the right session.

7. Trusted sources where you can accurately find out what time does the forex market open

Whether you’re new to forex or a seasoned trader, it's essential to rely on trusted platforms that provide accurate and up-to-date information on forex market hours. I’ve personally used the following sites to track changes, confirm session overlaps, and understand how economic events might influence when the forex market opens or closes.

Make a habit of bookmarking these resources. I’ve often set up notifications from economic calendars to avoid placing trades right before low-liquidity periods or high-impact announcements.
