The US forex trading session—centered on New York—is one of the most active and liquid periods in the global currency market. This guide explains what US forex trading times mean, how they work in practice, how to evaluate them, and what risks to keep in mind.
“US forex trading times” refer to the hours during which the New York session—the North American leg of the global foreign exchange market—is open for trading. The forex market operates 24 hours a day, five days a week, from Sunday at 5:00 PM Eastern Time (ET) to Friday at 5:00 PM ET[reference:0][reference:1]. The US session is the final major session of each trading day and plays a critical role in price discovery for USD pairs.
The New York session typically runs from 8:00 AM to 5:00 PM ET[reference:2][reference:3]. It overlaps with the London session between 8:00 AM and 12:00 PM ET, creating the most liquid and volatile trading window of the day[reference:4]. According to the Bank for International Settlements (BIS) Triennial Survey, global FX turnover reached $9.6 trillion per day in April 2025, up 28% from 2022[reference:5][reference:6]. The US dollar was on one side of 89% of all FX trades in that period[reference:7], underscoring the importance of US trading hours.
The US forex session does not operate in isolation. It is part of a continuous 24-hour cycle that moves from Sydney to Tokyo to London to New York[reference:9]. Each session has distinct characteristics:
The London–New York overlap (8:00 AM – 12:00 PM ET) is widely considered the most active period. During these four hours, two of the world’s largest financial centres are simultaneously open, generating roughly half of all daily FX volume[reference:14]. The BIS Triennial Survey notes that sales desks in the UK and US together accounted for 73% of OTC interest rate derivatives trading[reference:15], reflecting the concentration of liquidity in these time zones.
Daylight saving time changes can shift session opening and closing times. Countries adjust their clocks on different schedules, which means forex market hours can vary by an hour in March, April, October, and November[reference:16]. Always check your broker’s trading schedule for the most accurate times.
Understanding US forex trading times is not just academic—it has direct applications for different types of market participants.
Day traders and scalpers often focus on the London–New York overlap (8:00 AM – 12:00 PM ET) because spreads tend to be tightest and price movements most pronounced[reference:17]. Major USD pairs such as EUR/USD, GBP/USD, and USD/JPY see the highest liquidity during this window[reference:18].
Corporations with USD exposures use US trading hours to execute large hedges. The deep liquidity during the overlap reduces slippage and provides better execution for sizeable orders. The Federal Reserve’s H.10 weekly release, which contains daily noon buying rates for major currencies, is published on Mondays at 4:15 PM ET[reference:19] and is a key reference for corporate treasurers.
US economic data—such as Non-Farm Payrolls, CPI, and FOMC statements—are typically released during the New York session. Traders who follow US fundamentals often align their activity with the US session to react immediately to high-impact news[reference:20].
Portfolio managers rebalancing USD-denominated assets often prefer US hours to achieve best execution. The overlap with London ensures that both European and US liquidity providers are active, reducing the cost of currency conversion.
Not every trader needs to trade during US hours. Your strategy, time zone, and risk tolerance should guide your decision. Consider these evaluation criteria:
The table below compares the four major forex sessions, with a focus on how the US (New York) session fits into the weekly cycle.
| Session | Open (ET) | Close (ET) | Estimated Volume Share | Key Characteristics |
|---|---|---|---|---|
| Sydney | 5:00 PM Sun | 2:00 AM | ~5–7% | Quiet start; AUD/NZD pairs active |
| Tokyo | 7:00 PM | 4:00 AM | ~16–20% | Yen-focused; moderate volatility[reference:25] |
| London | 3:00 AM | 12:00 PM | ~32–35% | Busiest session; high liquidity[reference:26] |
| New York (US) | 8:00 AM | 5:00 PM | ~19–20% | USD pairs lead; overlap with London (8–12 AM) most active[reference:27] |

Before you trade during US hours, run through this checklist:
Scenario: A trader in Chicago plans to trade EUR/USD during the US session. It is 9:30 AM ET, and the London–New York overlap is in full swing. The trader checks the economic calendar and sees that US Initial Jobless Claims are due at 8:30 AM ET—already released with a slightly better-than-expected figure. The pair has moved 20 pips since the release.
The trader decides to enter a long position on EUR/USD, placing a stop-loss 15 pips below the entry and a take-profit 30 pips above. Within 45 minutes, the pair reaches the take-profit level as US bond yields edge lower. The trader closes the position, benefiting from the tight spreads and steady momentum during the overlap window.

❌ “The US session is the most volatile session overall.”
While the US session is highly liquid, the London session often sees the widest average pip movements[reference:33]. The US session’s volatility is concentrated during the overlap with London.
❌ “You can trade 24/7 without any breaks.”
The forex market is closed on weekends. From Friday 5:00 PM ET to Sunday 5:00 PM ET, spot FX is not actively traded[reference:34]. Some brokers offer weekend trading on certain instruments, but liquidity is extremely thin.
❌ “All US forex brokers offer the same trading hours.”
While the underlying market is global, individual brokers may have slightly different cut-off times for order execution, maintenance windows, or holiday schedules. Always check your broker’s specific hours.
❌ “The US session is only for USD pairs.”
USD pairs are certainly the most active, but cross pairs such as EUR/GBP, EUR/JPY, and GBP/JPY also see meaningful movement during US hours, especially when US data influences risk sentiment.
❌ “Higher volatility always means more profit potential.”
Volatility cuts both ways. The CFTC warns that two out of three forex customers lose money[reference:36]. Higher volatility can lead to larger losses if risk is not managed properly.
⚠️ Important Risk Warning
Trading foreign exchange on margin carries a high level of risk and may not be suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to trade forex, you should carefully consider your investment objectives, level of experience, and risk appetite[reference:37].
The Commodity Futures Trading Commission (CFTC) advises the public to thoroughly research any off-exchange forex dealer before making an initial deposit or transferring sensitive personal information. Verify that the firm and its employees are registered with the CFTC and check their disciplinary records through the NFA’s BASIC (Background Affiliation Status Information Center) database[reference:38][reference:39]. The NFA also publishes an investor guide, Trading Forex: What Investors Need to Know, which describes how the retail forex market operates and the risks involved[reference:40].
