The London–NY Overlap: When to Actually Trade
Forex trades 24/5, but liquidity isn't evenly distributed. Two specific hours produce most of the daily range. Trade those, ignore the rest.
Forex is a 24-hour market, but the volume distribution across those 24 hours is wildly uneven. If you treat the market as homogeneous, you'll trade hours that don't move. If you treat it as a series of sessions, you'll know exactly when to be at your desk.
The three main sessions
Asia (Tokyo) runs roughly 23:00–08:00 UTC. London runs 07:00–16:00 UTC. New York runs 12:00–21:00 UTC. The session names refer to the financial centres dominating the order flow, not to local trading hours.
Why the overlap matters
Between 12:00 and 16:00 UTC, London and New York are both fully open. This is the highest-liquidity, highest-volatility window of the trading day. For major pairs (EUR/USD, GBP/USD, USD/JPY), it's common for 50-70% of the daily range to print in this window.
Practical implications
- If you trade for an edge in volatility, sit in front of the chart for these four hours.
- If you're a swing trader, you can still ignore intraday — but know that overnight gaps and news reactions concentrate around session opens.
- Avoid the Asia session for major-pair scalping. It's tight, ranging, and prone to chop. Save it for Asian-pair specialists.
Most traders trade too much because they're always in front of the chart. Trade the overlap, walk away from the rest, and you've already cut your worst trades.
