Understanding the Four Major Trading Sessions

• Sydney Session

  22:00 – 07:00 UTC

  The Sydney session kicks off the trading week. Liquidity is lower than later sessions but provides early moves in AUD and NZD pairs. Australian economic data releases (RBA rate decisions, employment data) often trigger sharp moves during this window.

  • AUD
  • NZD

• Tokyo Session

  00:00 – 09:00 UTC

  The Tokyo session is the primary Asian trading window. JPY crosses see the most action, with Bank of Japan announcements and Japanese economic data driving volatility. SGD and HKD also see increased activity during this time.

  • JPY
  • SGD
  • HKD

• London Session

  08:00 – 17:00 UTC

  London is the world's largest forex trading center, accounting for roughly 35% of daily volume. EUR, GBP, and CHF pairs dominate. ECB and BoE announcements, eurozone data releases, and institutional flows create significant price action throughout the session.

  • EUR
  • GBP
  • CHF

• New York Session

  13:00 – 22:00 UTC

  New York is the second-largest trading center. USD pairs lead volume, especially during the London–New York overlap (13:00–17:00 UTC) when both centers are active. Fed announcements, NFP, and US economic data create the biggest moves of the day.

  • USD
  • CAD

Frequently Asked Questions

When does the forex market open?

The forex market is open 24 hours a day, 5 days a week — from Sunday 22:00 UTC (Sydney open) to Friday 22:00 UTC (New York close). Trading shifts across four major sessions: Sydney, Tokyo, London, and New York.

What are forex session overlaps?

Session overlaps occur when two major sessions trade simultaneously. The Tokyo–London overlap (08:00–09:00 UTC) and the London–New York overlap (13:00–17:00 UTC) produce the highest trading volume, tightest spreads, and strongest price moves — making them ideal for active traders.

What is the best time to trade forex?

The London–New York overlap (13:00–17:00 UTC) is widely considered the best time. Liquidity is at its peak, spreads are tightest on major pairs, and major US and European data releases drive clean directional moves. For Asian pairs, the Tokyo session (00:00–09:00 UTC) offers the best conditions.

Which sessions have the highest trading volume?

London leads with approximately 35% of daily forex volume, followed by New York at 20%. During their overlap, combined volume can exceed 50% of daily turnover. Sydney and Tokyo sessions carry lower volume but are optimal for AUD, NZD, and JPY pairs respectively.

Does the forex market close on weekends?

Yes. The forex market closes Friday at 22:00 UTC (New York close) and reopens Sunday at 22:00 UTC (Sydney open). Some brokers offer limited weekend trading on cryptocurrency pairs, but major currency pairs are unavailable from Friday evening to Sunday evening UTC.

How do session overlaps affect spreads?

Spreads typically tighten significantly during session overlaps because more market participants create deeper liquidity. During the London–New York overlap, EUR/USD spreads can be as low as 0.1–0.3 pips, whereas during the Sydney-only session they may widen to 1–2 pips.

What time does the London session open in my timezone?

The London session opens at 08:00 UTC (GMT). Convert to your local time: EST = 03:00 AM, CST = 02:00 AM, PST = 12:00 AM, IST = 01:30 PM, AEST = 06:00 PM (winter) / 07:00 PM (summer). Daylight saving changes shift these by one hour — always verify against UTC for accuracy.

Which currency pairs are most active during each session?

Sydney/Tokyo: AUD/USD, NZD/USD, USD/JPY, AUD/JPY. London: EUR/USD, GBP/USD, EUR/GBP, USD/CHF. New York: EUR/USD, USD/CAD, GBP/USD. Cross-pairs involving the session's local currencies see the tightest spreads and most volume during their home session.
