Forex session times in Eastern Time (ET) refer to the opening and closing hours of the four major global trading centres—Sydney, Tokyo, London, and New York—expressed in U.S. Eastern Time. Because the forex market is a decentralised network of financial institutions spanning multiple time zones, trading activity varies throughout the day. The Eastern Time zone is particularly significant because it houses the New York session, one of the two most liquid trading windows, and because many US-based traders operate on ET.
The forex trading day begins on Sunday evening at 5:00 PM ET with the opening of the Sydney session and ends on Friday at 5:00 PM ET with the close of the New York session. Within this continuous 24-hour cycle, each session has distinct characteristics: varying levels of liquidity, volatility, and participation from institutional and retail traders.
Understanding these session times in ET is not just about knowing when the market is open. It is about knowing when to trade specific currency pairs, when to expect tighter or wider spreads, and when to avoid potential slippage. For Eastern Time traders, this knowledge translates into better timing, reduced costs, and improved risk management.
The Bank for International Settlements (BIS) Triennial Central Bank Survey provides comprehensive data on global forex turnover, broken down by trading centre and time zone. According to BIS data, the London and New York centres together account for the majority of daily trading volume, reinforcing the importance of their session times for traders worldwide. The Federal Reserve also publishes exchange rate data that traders can use to verify rates during different sessions.
The following are the standard forex session times in Eastern Time, assuming standard time (EST, UTC-5) and no daylight saving adjustments:
These times shift by one hour during daylight saving periods, which we discuss later.
The most significant overlaps in Eastern Time are:
Each session has a distinct profile in Eastern Time:
Daylight saving time (DST) affects the timing of sessions because the US, UK, Australia, and Japan may not observe DST in sync. Generally:
Always verify the current DST status of each region to avoid confusion.
The U.S. Federal Reserve's economic calendar is a key reference for New York session traders. Major data releases (like Non-Farm Payrolls, CPI, and FOMC minutes) occur during the New York session, often between 8:30 AM and 10:00 AM ET. Understanding the ET session schedule helps traders align their activities with these high-impact events.
To fully understand forex session times in Eastern Time, familiarise yourself with these key terms:
The period when two major trading centres are simultaneously open, resulting in higher liquidity and volatility.
The ease with which an asset can be bought or sold without affecting its price. Higher liquidity means tighter spreads and faster execution.
The degree of price fluctuation within a given period. Higher volatility offers more profit opportunities but also greater risk.
The difference between the bid and ask price. Spreads tend to be tightest during high-liquidity sessions (London–NY overlap).
UTC-5, observed in the US eastern seaboard during winter months (November to March).
UTC-4, observed in the US eastern seaboard during summer months (March to November).
A schedule of important economic releases and events that can cause volatility during specific sessions.
The difference between the expected execution price and the actual fill price, more common during low-liquidity periods.
For day traders based in Eastern Time, the London–New York overlap from 8:00 AM to 12:00 PM ET is the prime window. This period offers the highest liquidity, tightest spreads, and the most significant price movements. It is ideal for scalping, momentum trading, and breakout strategies.
Many Eastern Time traders limit their activity to the New York session (8:00 AM – 5:00 PM ET), which aligns with the US business day. This session includes the US economic data releases that drive major moves in USD pairs.
For traders who prefer a quieter environment, the early London session (3:00 AM – 8:00 AM ET) offers moderate liquidity and fewer news-driven spikes. This can be a good time for range-bound strategies.
For swing traders holding positions across multiple sessions, understanding ET session times helps in setting stop-losses and take-profits that align with expected liquidity and volatility changes.
Scenario: James is a full-time forex trader based in New York. He primarily trades EUR/USD and GBP/USD. He structures his week around the session times in Eastern Time.
Monday: James starts his week by reviewing the market open. The Sydney session opens at 5:00 PM ET on Sunday, but he does not trade during that low-liquidity period. He prepares his watchlist for the London session.
Tuesday – Thursday: James wakes up at 7:30 AM ET, an hour before the London–NY overlap begins. He checks the pre-market activity and prepares his orders. From 8:00 AM to 12:00 PM ET, he actively trades, benefiting from tight spreads and strong trends. He closes all positions by 4:00 PM ET to avoid the late New York session when liquidity drops.
Friday: James follows the same routine but is cautious about the US Non-Farm Payrolls report, which is released at 8:30 AM ET. He reduces his position size to manage the increased volatility. He closes all trades by 5:00 PM ET when the New York session ends.
Key takeaway: James maximises his profitability by focusing on the most liquid hours in Eastern Time (8:00 AM – 12:00 PM ET) and avoids low-liquidity windows that could increase his trading costs.
Your trading style should dictate which session you focus on. Scalpers and day traders thrive during the London–NY overlap. Swing traders can operate across multiple sessions but should consider entry timing based on session characteristics.
Some brokers offer tighter spreads during the London session and wider spreads during the Sydney session. Evaluate your broker's execution quality during your preferred ET trading window.
US economic data is released during the New York session, often between 8:30 AM and 10:00 AM ET. If you trade USD pairs, you need to be aware of these times. Similarly, European data is released during the London session (3:00 AM – 8:00 AM ET).
If you are a part-time trader with a day job, the New York session (8:00 AM – 5:00 PM ET) may be your only option. The London session (3:00 AM – 12:00 PM ET) may be accessible for early risers.
False. Liquidity is highly concentrated during the London–NY overlap (8 AM – 12 PM ET). During the Sydney session, spreads are wider and execution can be slower.
Not necessarily. Some strategies work well in quieter sessions. However, the overlap offers the most opportunities for discretionary traders.
No. JPY pairs are more active during the Tokyo session (7 PM – 4 AM ET), while EUR and GBP pairs are more active during London (3 AM – 12 PM ET). Trade pairs that align with the active session.
Daylight saving time shifts session times by one hour. ET traders must adjust for DST changes in the US, UK, Europe, Australia, and Japan.
Trading during the Sydney session (5 PM – 2 AM ET) or at the session close can expose you to wider spreads and increased slippage.
Control: Focus your trading on the London and New York sessions, especially the overlap. If you must trade during quiet periods, use limit orders and reduce position size.
US and European data releases can cause sharp, unpredictable moves. The New York session (8 AM – 5 PM ET) is packed with high-impact events.
Control: Use an economic calendar set to Eastern Time to avoid trading during high-impact releases or adjust your position size and stop-loss levels to account for increased volatility.
Mis-calculating the session start time due to daylight saving can cause you to miss trades or enter at the wrong moment.
Control: Maintain a reliable time-zone converter. Many trading platforms automatically adjust for DST, but it is wise to verify session times manually at the start of each DST period.
Broker execution quality can vary by session. Some brokers have wider spreads or slower execution during low-liquidity periods.
Control: Test your broker's execution during different sessions on a demo account. Choose a broker with consistent execution across all sessions.
The U.S. Commodity Futures Trading Commission (CFTC) and the National Futures Association (NFA) emphasise that traders should understand the risks of trading during different market hours. The CFTC advises that "liquidity can vary significantly between trading sessions," and that traders should adjust their strategies accordingly. The NFA also recommends using limit orders to manage execution risk during low-liquidity periods.
The table below provides a detailed comparison of the four major forex sessions converted to Eastern Time, highlighting key characteristics.
| Session | ET Time (EST) | Liquidity Level | Typical Volatility | Best Pairs | Key Events | Suitability for ET Traders |
|---|---|---|---|---|---|---|
| Sydney | 5:00 PM – 2:00 AM | Low | Low–Moderate | AUD/USD, NZD/USD, AUD/JPY | Australian/NZ data | Poor (overnight) |
| Tokyo | 7:00 PM – 4:00 AM | Moderate | Moderate | USD/JPY, EUR/JPY, GBP/JPY | Japanese economic data | Poor (overnight) |
| London | 3:00 AM – 12:00 PM | High | High | EUR/USD, GBP/USD, USD/CHF | UK/EU economic data | Good (early morning) |
| New York | 8:00 AM – 5:00 PM | High (overlap: very high) | High (overlap: very high) | USD/JPY, USD/CAD, EUR/USD, GBP/USD | U.S. economic data | Excellent (working hours) |
| London–NY Overlap | 8:00 AM – 12:00 PM | Very High | Very High | All major pairs | U.S. data releases (8:30–10:00 AM) | Best (morning) |
Note: EST = Eastern Standard Time (UTC-5). Times shift by one hour during daylight saving time (EDT, UTC-4). Always check current DST status.
Use this checklist to optimise your trading approach based on Eastern Time session scheduling:
Forex trading carries substantial risk and is not suitable for all investors. Trading during certain sessions may expose you to higher volatility, wider spreads, and increased slippage. Past performance of session-based strategies does not guarantee future results.

The four major forex sessions in Eastern Time (ET) are: Sydney (5:00 PM – 2:00 AM ET), Tokyo (7:00 PM – 4:00 AM ET), London (3:00 AM – 12:00 PM ET), and New York (8:00 AM – 5:00 PM ET). The London–New York overlap runs from 8:00 AM to 12:00 PM ET, offering the highest liquidity and volatility.
The London session opens at 3:00 AM Eastern Time (ET) and closes at 12:00 PM ET during standard time (EST). During daylight saving time, when the UK is on British Summer Time (BST), the London session opens at 4:00 AM EDT and closes at 1:00 PM EDT.
The New York session opens at 8:00 AM Eastern Time (ET) and closes at 5:00 PM ET. It overlaps with the London session from 8:00 AM to 12:00 PM ET, which is the most active trading period of the day.
The London–New York overlap occurs from 8:00 AM to 12:00 PM Eastern Time (ET). During this period, both major financial centres are open simultaneously, producing the highest liquidity, tightest spreads, and greatest volatility in the forex market.
Daylight saving time shifts session times by one hour. When the US is on EDT (UTC-4) and the UK is on BST (UTC+1), the London session opens at 4:00 AM EDT instead of 3:00 AM EST. The Sydney and Tokyo sessions also shift by one hour. Always check the current daylight saving status of each region.
The best hours for forex trading in Eastern Time are during the London–New York overlap from 8:00 AM to 12:00 PM ET, when volatility and liquidity are highest. The early London session (3:00 AM – 8:00 AM ET) and the early New York session (8:00 AM – 10:00 AM ET) are also good for active trading.
Trading outside peak hours (e.g., during the Sydney session or late New York) exposes you to lower liquidity, wider spreads, and higher slippage. This can increase trading costs and the risk of unfavourable fills. Always consider these factors when planning your trading schedule.
The Bank for International Settlements (BIS) publishes the Triennial Central Bank Survey, which provides detailed data on forex turnover by location and currency. The U.S. Federal Reserve also publishes exchange rate data. These official sources are useful for understanding market activity across different time zones.
