What Are Forex Trading Hours?

Forex Trading Hours are the time frames when financial centers around the world are open, allowing traders to participate in buying and selling currency pairs. This market operates continuously thanks to the global connection of the banking system, brokerage platforms, and individual investors.

Generally, the market starts operating from Monday at 06:00 a.m. (Singapore time) when the Sydney session opens, and ends on Saturday at 06:00 a.m. when the New York session closes. Throughout this period, there is always at least one trading session open, helping the Forex market maintain high liquidity and continuous operation.

Main Trading Sessions in Forex

The market is divided into 4 main trading sessions: Sydney, Tokyo, London, and New York. These are major financial centers, accounting for up to 75% of global trading volume.

Sydney Session

Opening hours: 06:00 – 14:00 (Singapore time).
This is the first session to open during the week and is usually less volatile than other sessions.
Popular currency pairs: AUD/USD, NZD/USD, USD/SGD.

Tokyo Session

Opening hours: 08:00 – 17:00 (Singapore time).
It is the major trading center in Asia, focusing heavily on currency pairs related to JPY.
Popular currency pairs: USD/JPY, EUR/JPY, GBP/JPY.

London Session

Opening hours: 16:00 – 00:00 (Singapore time).
This is the most active session, accounting for more than 30% of total global trading volume.
Popular currency pairs: EUR/USD, GBP/USD, EUR/GBP.

New York Session

Opening hours: 21:00 – 06:00 (Singapore time).
This is the final trading session of the day and is also very important due to its overlap with London.
Popular currency pairs: USD/CAD, USD/CHF, EUR/USD.

The Overlap Between Trading Sessions

One of the important characteristics of Forex Trading Hours is the overlap between sessions. This is the time when the market has the highest liquidity and volatility.

Sydney and Tokyo: 08:00 – 14:00 SGT → focused mainly on Asia–Pacific currency pairs.
Tokyo and London: 16:00 – 17:00 SGT → volatility increases slightly as the market shifts from Asia to Europe.
London and New York: 21:00 – 00:00 SGT → the most active period, accounting for the majority of global trading volume.

Example: The EUR/USD pair experiences the strongest volatility during the London and New York overlap, because both the euro and the US dollar are heavily traded in these two centers.

The Impact of Forex Trading Hours on Traders

Understanding Forex Trading Hours helps traders:

Capture price movements: Knowing when the market is active to seize opportunities.
Manage risk better: Trading during quiet hours can lead to slippage due to low liquidity.
Choose suitable currency pairs: Each session has specific major currency pairs that are more active.
Optimize personal strategies: Scalpers often prefer trading during the London – New York session, while long-term traders may choose quieter time frames.

When Is the Best Time to Trade Forex?

There is no single “golden hour” for everyone, but in general, the best time usually falls during overlapping sessions when liquidity is high:

London – New York (21:00 – 00:00 SGT): Strongest volatility, suitable for short-term trading.
Sydney – Tokyo (08:00 – 14:00 SGT): Good for traders interested in Asia–Pacific currency pairs.
Tokyo – London (16:00 – 17:00 SGT): Less active but still offers opportunities.

Traders need to consider their personal strategy, risk appetite, and daily time zone schedule to choose the most suitable time.

Factors to Note When Monitoring Forex Trading Hours

Daylight Saving Time: Some countries such as the US and the UK change trading hours in March, April, October, and November.
Economic news: GDP, CPI, and central bank interest rates are usually released according to local time, causing strong volatility.
Unusual events: Political crises, natural disasters, and global news can have an impact regardless of trading hours.
Personal habits: Traders should trade when they are most alert, instead of forcing themselves into very late or very early time frames.
