When Does Forex Market Open?
2026 Update

The London-New York Overlap (13:00–17:00 GMT)

The London-New York overlap is widely monitored because two of the largest forex markets operate simultaneously.

This period typically occurs around:

• 8:00 AM – 12:00 PM EST
• 1:00 PM – 5:00 PM GMT

During this overlap, liquidity often increases because European and North American participants are active at the same time. Major currency pairs, including EUR/USD and GBP/USD, may experience higher trading volume and more noticeable price movements.

Traders researching trading session times EST often pay attention to this period since it aligns with major US economic announcements and active European market hours.

However, increased activity does not automatically indicate favorable conditions for every strategy. Some traders prefer higher volatility, while others may focus on calmer market environments.

The Sydney-Tokyo Overlap (00:00–07:00 GMT)

The Sydney-Tokyo overlap represents the transition between Australian and Asian market activity.

During this period:

• AUD and NZD pairs may receive increased attention
• regional economic data can influence price movements
• liquidity may improve compared with the earlier Sydney session

Although this overlap generally has lower activity than the London-New York period, it can still be relevant for traders focusing on Asia-Pacific currencies.

Lower-Liquidity Periods

Some periods of the trading day experience lower participation because major financial centers are between sessions. Lower liquidity may affect:

• bid/ask spreads
• price movement patterns
• order execution conditions

For example, the period after New York closes and before Asian markets become fully active often sees reduced market participation.

Therefore, you should monitor these periods carefully, especially when trading strategies depend on short-term price movements.

The Global Impact of Daylight Saving Time (DST)

Daylight Saving Time creates seasonal changes in how trading hours appear across regions. While financial markets usually maintain their local operating schedules, the conversion between time zones can shift during DST transitions. For example:

• The United States and Europe do not switch to DST on the same date.
• Some countries, including Japan, China, Hong Kong, Singapore, and India, do not observe DST.
• The same forex session may appear one hour earlier or later depending on the trader's location.

These differences can affect traders who follow specific session schedules, economic releases, or automated trading systems. Professional trading systems often use Coordinated Universal Time (UTC) internally to reduce confusion caused by seasonal time changes.

Holiday Trading Liquidity and Spread Risks

Although the forex market does not completely close because of most regional holidays, liquidity can change when major financial institutions are unavailable. During holidays such as US or UK bank holidays:

• fewer institutional participants may be active
• trading volume can decrease
• spreads may become wider
• price movements may behave differently

For example, when US equity markets close during major federal holidays, broader market participation may also decline.

Traders should consider holiday schedules when evaluating market conditions, especially if their approach relies on short-term execution or high liquidity environments.
