Forex runs 24 hours on weekdays, but not all hours are equal. Knowing the sessions tells you when liquidity, volatility and spreads are favourable.

The four sessions

The market rolls westward: Sydney opens the week, then Tokyo, then London (the largest by volume), then New York. Each session favours different pairs — JPY pairs are active in Tokyo, EUR and GBP pairs in London.

The overlaps that matter

The London–New York overlap (roughly early-to-mid afternoon London time) is the most liquid, highest-volume window, with the tightest spreads and the cleanest moves. Many traders focus their work here.

Trading your own timezone

From the Middle East, the London open and the London–NY overlap fall in the afternoon and evening — convenient and high-quality. Trading thin hours (late NY into Sydney) usually means wider spreads and choppier price; pick your window deliberately.

Key takeaways

  • Sessions roll Sydney → Tokyo → London → New York; London is largest.
  • The London–New York overlap is the most liquid, tightest-spread window.
  • Pick a session that suits your timezone and avoid thin, choppy hours.
