Forex Trading Sessions: How the Market Runs 24/5

Forex trades nearly 24 hours a day, five days a week, because it’s not centered on a single exchange — instead, trading passes between major financial centers around the world as each one opens and closes.

The four main sessions

The market is generally divided into the Sydney, Tokyo, London, and New York sessions. As one session winds down, another is opening, keeping the market continuously active from Monday morning in Asia through Friday evening in New York.

Why overlaps matter

The busiest, most liquid periods happen when two sessions overlap — especially the London/New York overlap, which covers a large share of global daily trading volume. Spreads tend to be tighter and price moves more decisive during these overlaps.

Quieter periods

Sessions like the late Sydney/early Tokyo window tend to be quieter, with lower volume and choppier, less predictable price action — often less ideal for short-term strategies that rely on strong momentum.

Key takeaway

Knowing which session you’re trading in helps set expectations for volatility and liquidity. Many traders align their strategy — and the pairs they focus on — with the session that suits it best.
