The forex market runs 24 hours a day, 5 days a week, but not all hours are equal in terms of liquidity and volatility. During the busiest market hours, there are more participants trading, which means:
When you trade during peak hours, you typically get faster fills and better pricing. In contrast, off-peak hours often mean wider spreads and slower price action. For instance, many brokers report wider spreads during late New York hours due to low liquidity, and much tighter spreads during the London–New York overlap when activity peaks.
The global forex market is typically divided into four major trading sessions, each aligned with a key financial center. Below are the four sessions and their approximate UTC time ranges (market hours can shift slightly with local daylight savings adjustments):
| Trading Session | Typical UTC Open | UTC Close |
| Sydney (Pacific) | 10:00 PM | 7:00 AM |
| Tokyo (Asian) | 12:00 AM | 9:00 AM |
| London (European) | 8:00 AM | 4:00 PM |
| New York (US) | 1:00 PM | 9:00 PM |
The first to open for the week (10 PM to 7 AM UTC), marking the start of the trading day. Activity is initially modest since it’s the smallest major market, but it sets the tone for early moves, especially in AUD and NZD currency pairs.
Overlaps with late Sydney hours, running from midnight to 9 AM UTC. Tokyo is the heart of the Asian session and brings more volume. The Asian session tends to have steadier, lower-volatility trends compared to London/NY. Key market drivers here include news from Japan, China, and Australia. Major yen pairs like USD/JPY and cross-pairs like EUR/JPY are most active during Tokyo hours.
The European session (8 AM to 4 PM UTC) is the largest forex market by volume – London alone handles about 38–40% of global FX trading. With Europe awake and Asia/ Pacific traders still active in early London morning, this session sees high liquidity. Major European pairs (EUR, GBP, CHF crosses) and euro-denominated crosses are particularly active. Traders often observe that London’s open can set daily trends, and indeed, this session is typically the most volatile of the day. London’s high volume also means transaction costs can be lower (tighter spreads) during this period.
The U.S. session (1 PM to 9 PM UTC) starts as London is midway through its day. New York is the second-largest forex hub, responsible for roughly 17-20% of daily volume. This session keeps liquidity high for USD pairs, especially when it overlaps with London in the early afternoon UTC. By New York afternoon (after London closes), trading can slow down. Still, during U.S. morning hours, major USD pairs like EUR/USD, GBP/USD, USD/JPY, USD/CHF, and USD/CAD see heavy action due to U.S. economic news and active equity markets.
Between each major session, there are periods when two markets are open simultaneously. These session overlaps are often the most dynamic times of day, because traders from two regions are active at once, driving volume and volatility up. Naturally, when liquidity pours in from multiple time zones, price movements can be larger and spreads tighter.
The Sydney and Tokyo sessions overlap roughly between 12:00 AM and 7:00 AM UTC. This combined Asian trading window tends to energize currency pairs tied to the Asia-Pacific region. For example, JPY and AUD pairs become more active, and common movers include USD/JPY, AUD/JPY, NZD/JPY, as well as AUD/USD and NZD/USD. These currencies’ home markets are open, so you often see steadier flows and reactions to regional news in this overlap.
From 7:00 to 9:00 AM UTC, Tokyo winds down as London comes online. Though brief, this window can still bring a surge in activity, especially in pairs like EUR/JPY and GBP/JPY, as European traders respond to late Asian session developments. While it's less liquid than other overlaps, it often delivers a volatility bump in yen and AUD pairs as Europe begins to digest overnight news.
This is the major overlap that forex traders watch. From about 1:00 PM to 4:00 PM UTC, the London and New York sessions are both trading at full steam. It’s typically the most liquid and volatile time of the trading day. Major pairs like EUR/USD, GBP/USD, USD/JPY, USD/CHF, and other USD crosses see peak volume. That’s due to the sheer number of active market participants, banks, hedge funds, corporations, and the release of key U.S. economic data during this window. For many traders, this is the “golden hour” of forex, filled with fast price moves and plentiful opportunities.
Session overlaps matter because that’s when market liquidity is at its daily maximum, often leading to the most notable price swings and tighter spreads. The London–New York overlap is the busiest period of all, making it a prime time for traders seeking volatility.
Each currency pair has certain windows when it tends to be most active. These high-activity periods usually align with the business hours of the countries involved in the pair.
As the most traded pair, EUR/USD sees peak action when both Europe and the U.S. are active, especially during the London–New York overlap (13:00–16:00 UTC). This is when major data releases and heavy order flow hit, driving strong volatility and liquidity. The earlier part of the London session (European morning) is also busy, while late U.S. hours and the Asian session tend to be quieter.
The British pound vs. U.S. dollar is most active during London hours and the U.S. session, with volatility peaking during the 12:00–16:00 UTC overlap (sometimes until 17:00 UTC in winter). During this window, both markets react to news, and liquidity is highest. Studies even show this overlap as the pair’s optimal trading time. By contrast, Asian hours are usually slow for GBP/USD.
This pair comes alive twice a day. The Asian session (00:00–09:00 UTC) sees steady movement as Tokyo leads the market, often reacting to BoJ updates or Japanese data. The second wave comes during the New York session, especially with U.S. reports or stock market shifts. USD/JPY is typically less active during London-only hours, as most volume comes from Asian and U.S. trading desks. It’s a pair shaped by both sides of the globe.
Other major USD pairs follow similar logic: for example, USD/CHF largely aligns with EUR trading hours and the U.S. overlap, and USD/CAD is most active during the New York session, given the Canadian and U.S. market timings. Meanwhile, AUD/USD and NZD/USD often see increased movement during the Pacific/Asian sessions when commodity news or local data from Australia/New Zealand emerges.
News doesn’t follow session rules, and even calm hours can explode with movement when big events hit. That’s why traders track the economic calendar closely.
In practical terms, if you choose to trade around news releases, you should be prepared for rapid price changes. Many traders either avoid trading right when major news hits, or they plan strategies specifically to trade the heightened volatility. Knowing the schedule of key news like NFP, central bank meetings, GDP releases, and inflation reports is part of timing your trades wisely.
The best trading time depends on your lifestyle and strategy. Here’s how to find what works for you:
Every trader is different. What works for one person might not suit another, and there’s no single “best” time to trade. The key is finding what fits your lifestyle, strategy, and risk tolerance. Some may thrive in the fast-paced London–New York overlap, while others prefer the steadier flow of the Asian session. Likewise, not everyone is comfortable trading during high-impact news events or volatile overlaps, and that’s completely okay.
Ultimately, success in forex trading isn’t just about when you trade. It’s about trading smart, keeping up with news, and choosing what’s right for you.
