The forex market operates 24 hours a day, five days a week, but not all hours are created equal. Understanding forex market hours in Eastern Time (ET) is essential for traders who want to optimise their trading strategies, manage risk, and capitalise on peak liquidity periods. This guide explains the meaning of market hours in ET, their practical use cases, how to evaluate session characteristics, and the risks associated with trading at different times of the day.
The forex market is decentralised and operates 24 hours a day from Sunday evening to Friday evening (ET) because trading occurs across multiple global financial centres. Forex market hours Eastern Time refers to the standardised schedule of when these centres are open, expressed in the Eastern Time zone (UTC-5 during standard time, UTC-4 during daylight saving time).
The trading week begins with the opening of the Sydney session on Sunday at 5:00 PM ET and closes with the end of the New York session on Friday at 5:00 PM ET. This continuous cycle is divided into four major trading sessions: Sydney, Tokyo, London, and New York. Each session has distinct characteristics in terms of volatility, liquidity, and the currency pairs that are most active.
According to the Bank for International Settlements (BIS), the forex market averages over US$7.5 trillion in daily turnover. The distribution of this trading volume is not uniform across sessions; the London and New York sessions together account for the majority of global trading activity. Understanding these dynamics can help traders align their strategies with periods of highest liquidity and lowest spreads.
The forex market is divided into four primary sessions. Below is a breakdown of each session in Eastern Time, including its key characteristics.
| Session | Eastern Time (ET) | Key Financial Centres | Liquidity Level | Volatility Level | Major Active Pairs |
|---|---|---|---|---|---|
| Sydney | 5:00 PM – 2:00 AM | Sydney, Wellington | Low to Moderate | Moderate | AUD/USD, NZD/USD, AUD/JPY |
| Tokyo | 7:00 PM – 4:00 AM | Tokyo, Hong Kong, Singapore | Moderate | Moderate | USD/JPY, EUR/JPY, GBP/JPY |
| London | 3:00 AM – 12:00 PM | London, Frankfurt, Zurich | High | High | EUR/USD, GBP/USD, USD/CHF |
| New York | 8:00 AM – 5:00 PM | New York, Chicago | High | High | All majors, USD crosses |
The periods when two sessions overlap are particularly significant:
The London/New York overlap is often considered the “prime time” for forex traders, as it offers the tightest spreads and the most significant price movements. The BIS data confirms that trading volume peaks during this overlap, making it the optimal window for many strategies.
Liquidity refers to the ease with which an asset can be bought or sold without affecting its price. During major session overlaps, liquidity is highest, which typically results in tighter spreads. During off-peak hours, liquidity drops, spreads widen, and price movements can become erratic. This is particularly noticeable during the Sydney session and the hours between the New York close and Sydney open.
Traders who use my forex calculator to estimate costs should account for spread variations based on the time of day. A strategy that is profitable during the London/New York overlap may not be cost-effective during the Sydney session due to wider spreads.
Volatility is not constant throughout the day. Major economic releases — such as US Non-Farm Payrolls, Federal Reserve announcements, or European Central Bank rate decisions — can cause sudden spikes in volatility. These events are typically scheduled during the London or New York sessions, making those periods both opportunity-rich and risk-heavy.
Different currency pairs are most active during specific sessions:
Day traders who enter and exit positions within the same session benefit from knowing when liquidity and volatility are highest. They typically focus on the London and New York sessions, avoiding low-volume periods that can produce choppy price action.
Swing traders, who hold positions for several days, need to understand session overlaps to time their entries and exits. They may also use session-specific high and low levels as support and resistance references.
Scalpers rely on tight spreads and high liquidity. They typically trade during the London/New York overlap, where spreads are narrowest and price movements are frequent enough to generate small, repeated profits.
Traders with day jobs can use market hours to plan their trading around their availability. For example, a trader on the US East Coast can focus on the New York session (8:00 AM – 5:00 PM ET), while a trader in Europe can trade the London session (3:00 AM – 12:00 PM ET).
Institutional risk managers use session analysis to control exposure. They may reduce position sizes during low-liquidity periods or avoid trading during major news releases that could cause adverse price gaps.
Traders who specialise in trading economic releases need to know exactly when data will be published — typically during the London or New York sessions. They also need to be aware of which session will react most strongly to a given piece of news.
The NFA and FINRA highlight that understanding market hours is a fundamental component of a trader's education. The CFTC also warns that trading during low-liquidity periods can increase the risk of slippage and unfavourable fills, which can erode profits.
To make informed trading decisions, it is essential to evaluate the characteristics of each session. Use the following framework to assess which sessions align with your trading style.
| Characteristic | Sydney | Tokyo | London | New York |
|---|---|---|---|---|
| Typical Spread (EUR/USD) | 1.5–2.5 pips | 1.2–2.0 pips | 0.5–1.2 pips | 0.6–1.3 pips |
| Average Daily Range (EUR/USD) | 40–60 pips | 50–70 pips | 80–120 pips | 70–100 pips |
| News Impact | Low (limited economic releases) | Moderate (Asian data) | High (European data, BOE) | Very High (US data, Fed) |
| Trading Style Suitability | Range trading, breakout | Breakout, trend following | Scalping, day trading, trend | Day trading, news trading |
| Risk Level | Moderate | Moderate | High | High |
Situation: A day trader in New York wants to trade EUR/USD during the highest-liquidity period. They choose to trade from 8:00 AM to 12:00 PM ET, when both London and New York are open.
Observation: During this overlap, spreads on EUR/USD tighten to 0.6–0.8 pips, and the average daily range is around 80–100 pips. The trader can enter and exit positions with minimal slippage.
Strategy: The trader uses a breakout strategy, placing pending orders above the session's opening range. They set a stop-loss of 20 pips and a take-profit of 40 pips, aiming for a 2:1 reward-to-risk ratio.
Outcome: Over the course of two weeks, the trader achieves a 55% win rate, with an average net profit of 15 pips per trade after spreads.
› This example highlights how trading during the overlap can reduce costs and increase the likelihood of smooth execution.
Situation: A swing trader based in Asia considers trading GBP/JPY during the Sydney session (5:00 PM – 2:00 AM ET) because it fits their schedule. However, they notice that spreads on GBP/JPY widen to 4–5 pips during this period, compared to 2–3 pips during the London session.
Decision: The trader decides to place limit orders and check them during the Sydney session, but they only execute trades during the London session (3:00 AM – 12:00 PM ET) when liquidity is higher and spreads are tighter.
Outcome: By avoiding the low-liquidity Sydney session, the trader saves approximately 2 pips per trade in spread costs, which adds up to significant savings over time.
› This scenario demonstrates the importance of aligning your trading schedule with periods of optimal liquidity for your chosen instrument.
Situation: A news trader wants to trade the US Non-Farm Payrolls (NFP) release, which occurs on the first Friday of each month at 8:30 AM ET, during the London/New York overlap.
Preparation: The trader uses a my forex calculator to estimate the pip value and potential profit/loss of their planned position size. They also calculate the margin required to ensure they have sufficient free margin.
Execution: The trader places pending orders 20 pips above and below the current price just before the release. They set a stop-loss of 30 pips and a take-profit of 60 pips.
Outcome: The price spikes 50 pips in one direction, triggering the take-profit. The trader captures a 60-pip move, but they also experience slippage of 2 pips due to the high volatility. The net profit is still positive.
› News trading is high-risk, but understanding session timing helps traders prepare for the volatility. The CFTC and NFA warn that slippage and widened spreads are common during news events.
The FINRA and CFTC both emphasise that understanding market hours is part of fundamental trader education. The Federal Reserve also publishes economic calendars that help traders anticipate periods of heightened volatility.
Trading forex carries substantial risk, and timing your trades based on market hours does not eliminate this risk. Slippage, widening spreads, and gaps are inherent features of the forex market that can lead to significant losses. Always verify current spreads, margin requirements, and execution policies directly with your broker — especially during off-peak hours or news events. This guide is for educational purposes only and does not constitute financial, legal, or tax advice.
For investor education, refer to the CFTC's retail forex education, the NFA's investor protection resources, FINRA's trading risk materials, and the Federal Reserve's economic data and calendars. These authorities provide guidance on understanding and managing trading risks.
The forex market opens on Sunday at 5:00 PM ET and closes on Friday at 5:00 PM ET. Trading is continuous during these hours, with the four major sessions — Sydney, Tokyo, London, and New York — overlapping to provide 24-hour market access.
The best time to trade is generally during the London/New York overlap, from 8:00 AM to 12:00 PM ET. This period offers the highest liquidity, tightest spreads, and the most significant price movements. However, the best time ultimately depends on your trading strategy and the currency pairs you trade.
The London/New York overlap occurs from 8:00 AM to 12:00 PM ET. During this 4-hour window, both major financial centres are open simultaneously, creating the most liquid and volatile trading conditions of the day.
Yes, daylight saving time affects trading hours as different countries change their clocks on different dates. For example, the US and UK may have a 1-hour difference in their DST transitions. Always check the current session times for your specific time zone, as they can shift by an hour during these periods.
During the Asian session (Tokyo), JPY pairs such as USD/JPY, EUR/JPY, and AUD/JPY are most active. The session also sees movement in AUD/USD and NZD/USD, driven by economic data from Australia and New Zealand.
Not necessarily. The Sydney session offers opportunities, especially for traders focusing on AUD and NZD pairs. However, liquidity is lower, and spreads are wider compared to the London and New York sessions. If you trade during this session, consider using range-bound strategies and wider stop-losses.
Most trading platforms display the current session and market hours. You can also use online forex market hour calculators that convert your local time to ET. Additionally, your broker's platform often shows the session status. The Federal Reserve and BIS also provide historical and current market data.
Yes, the forex market closes on Friday at 5:00 PM ET and reopens on Sunday at 5:00 PM ET. During this weekend gap, you cannot trade, and positions held over the weekend are subject to potential price gaps when the market reopens.
