Forex opens on Sunday evening in the United States, typically between 5 p.m. and 6 p.m. Eastern Time

The exact opening time depends on your broker and which market session you're entering. Most U.S.-based forex brokers begin accepting trades at 5 p.m. ET on Sunday, though some open as early as 4 p.m. ET or as late as 6 p.m. ET. The variation exists because forex is not a centralized exchange — it's a network of banks, brokers, and traders spread across time zones, and each broker sets its own Sunday opening window.

When U.S. brokers open on Sunday evening, the Asian markets (Tokyo, Hong Kong, Singapore) are already trading Monday morning their local time. This overlap is why Sunday evening U.S. time is considered the start of the global forex week, even though markets in Asia have been open for hours.

Check your specific broker's trading hours before Sunday evening. Most brokers publish this information on their platform or website under "Market Hours" or "Trading Hours." If you're unsure, contact your broker directly — the difference between 5 p.m. and 6 p.m. ET can matter if you're planning to enter a trade at market open.

Key Takeaways

  • Most U.S. brokers open forex trading on Sunday between 5 p.m. and 6 p.m. Eastern Time, though the exact time varies by broker.
  • Sunday evening U.S. time aligns with Monday morning in Asian markets, which is why it marks the start of the global forex trading week.
  • Liquidity and volatility are typically lower in the first hour after Sunday opening compared to weekday sessions.
  • Your broker's specific opening time is listed in their trading hours documentation, which you should check before placing a trade.

Why Sunday Opening Times Vary Between Brokers

Forex brokers don't all open at the same moment because they operate independently and may route orders through different liquidity providers. A broker using a Tokyo-based liquidity provider might open earlier than one using a London-based provider. Some brokers also stagger their opening to manage server load or to align with their own operational schedule.

The 5 p.m. to 6 p.m. ET window is conventional because it's when enough liquidity enters the market to make trading practical. Before 5 p.m. ET on Sunday, bid-ask spreads (the cost of entering a trade) tend to be wider, and fewer orders are being filled. After 6 p.m. ET, liquidity is usually sufficient that most brokers are fully operational.

Some brokers offer "Sunday trading" that opens even earlier — as early as 4 p.m. ET — but spreads at that hour are often significantly wider, meaning you pay more to enter and exit positions. If you're considering early Sunday trading, compare the spread cost against the benefit of entering earlier.

Liquidity and Volatility in the First Hour After Sunday Opening

The first hour after Sunday opening is typically slower than weekday trading. Fewer traders are active, volumes are lower, and price movements can be more erratic because smaller trades have a larger effect on the market. This means spreads are wider and slippage (the difference between the price you see and the price you actually get) is more common.

If you're planning to trade Sunday evening, expect to pay more in spread costs than you would during peak hours on Tuesday or Wednesday. Some traders deliberately wait until Monday morning (U.S. time) when European and U.S. markets overlap, because liquidity is much higher and spreads tighten.

Price gaps can also occur between Friday's close and Sunday's open. If major news happened over the weekend, the market may open at a significantly different price than where it closed Friday. This gap can work for or against you depending on your position.

How to Find Your Broker's Exact Sunday Opening Time

Log into your trading platform and look for a "Market Hours," "Trading Hours," or "Session Times" section. Most brokers display this prominently in the Help menu or on their website's FAQ page. The information should specify the opening time in your local time zone or in ET, GMT, and other major zones.

If you can't find it on the platform, call or email your broker's customer service. They can confirm the exact time and also tell you whether spreads are wider at opening or if there are any restrictions on order types (some brokers don't accept certain order types in the first few minutes after opening).

Write down your broker's opening time and set a reminder if you plan to trade at that moment. The difference between planning to trade at 5 p.m. and discovering your broker opens at 6 p.m. can disrupt your trading plan.

Sunday Opening Times Across Different Time Zones

If you're outside the United States, convert 5 p.m. to 6 p.m. ET to your local time. London is typically 5 hours ahead of ET, so Sunday 5 p.m. ET is 10 p.m. GMT. Tokyo is 14 hours ahead, so it's already Monday 7 a.m. JST. Sydney is 16 hours ahead, so it's Monday 9 a.m. AEDT (during daylight saving).

The exact conversion depends on whether daylight saving time is in effect. During U.S. daylight saving (March to November), ET is UTC-4. During standard time (November to March), ET is UTC-5. Check a time zone converter if you're unsure, because the difference matters for your trading schedule.

Some brokers in other countries may have different opening times aligned to their local market. If you're using a broker based in the UK, Asia, or Australia, confirm their Sunday opening time separately — it may not match U.S. broker times.

What Happens if You Try to Trade Before Your Broker Opens

Most trading platforms simply won't accept orders before the market opens. You may see a message like "Market is closed" or "No liquidity available." Your order won't be placed, and you won't be charged a fee for attempting.

Some brokers allow you to place pending orders (orders that execute automatically when the market opens at a specified price), but these carry risk. If the market opens at a price far from where you set your pending order, it may execute at a much worse price than you expected, or not execute at all if the price never reaches your target.

The safest approach is to wait until your broker confirms the market is open, then place your order. This takes only a few minutes after the official opening time and gives you visibility into actual market prices.

Frequently Asked Questions

Does forex open at the same time every Sunday?

Yes, forex opens at the same time every Sunday (typically 5 p.m. to 6 p.m. ET depending on your broker), but the exact time may shift by one hour when daylight saving time begins or ends in the U.S. Check your broker's hours after daylight saving changes in March and November.

Can I trade forex on Saturday?

Most brokers do not offer forex trading on Saturday. The market closes Friday afternoon (U.S. time) and reopens Sunday evening. A few brokers offer limited Saturday trading, but liquidity is extremely low and spreads are very wide, making it impractical for most traders.

What if I'm in a country that doesn't observe daylight saving time?

Your broker's opening time will shift by one hour relative to your local time when the U.S. switches to or from daylight saving. If you're in a country without daylight saving, recalculate the conversion twice a year (in March and November) to stay aligned with your broker's actual opening time.

Is it better to trade right when the market opens on Sunday?

Not necessarily. Spreads are typically wider and liquidity is lower in the first hour after Sunday opening. Many traders wait until Monday morning (U.S. time) when European and U.S. markets overlap, because spreads are tighter and price movement is more predictable.

What if my broker's opening time is different from what I expected?

Contact your broker directly. They can confirm the exact opening time and explain any differences. Some brokers also offer extended hours or different opening times for different currency pairs, so clarify which pairs you plan to trade.
