The Forex market runs 24 hours a day, five days a week — but that does not mean every hour is worth trading. Liquidity, spreads and volatility shift dramatically as the world's financial centres open and close. Here is when the market actually comes alive.
The four major sessions
- Sydney — opens the trading week, generally quieter.
- Tokyo (Asian) — JPY and AUD pairs get more active.
- London (European) — the largest session by volume; spreads tighten and trends form.
- New York (US) — high activity, especially around US data.
The overlaps that matter most
Volatility peaks when two big sessions are open at once:
- London / New York overlap — typically the most active window of the day, with the tightest spreads and the cleanest moves on major pairs.
- Tokyo / London overlap — a smaller bump in activity, useful for some crosses.
Why timing affects your edge
- Spreads are narrowest when liquidity is deepest — trading thin hours quietly costs you more.
- Volatility during overlaps means more opportunity, but also more risk.
- News timing — major releases (US, UK, Eurozone) can spike pairs in seconds.
Practical takeaway
You do not need to trade all day. Many traders focus on the London and New York hours and step aside during thin, choppy periods. Our regime filter does something similar — it down-weights setups during low-liquidity windows.
Trade when the market is awake, not when you happen to be bored.
