Trading session
The London-New York overlap
Four hours when London and New York are simultaneously open. The peak-liquidity window of the week.
- Hours
- 13:00 - 17:00 UTC
Why it matters
Most of the day's FX volume - and a large share of equity volume in dual-listed names - occurs in these four hours.
Macro releases
US economic data prints at 08:30 or 10:00 ET land directly in this window, with both regions open to react.
Practical effect
Spreads on major FX pairs and large-cap equities are at their tightest, and slippage on size is at its lowest.
