Rollover Time and the 5pm New York Convention
Posted: Mon Oct 26, 2026 12:08 pm
The forex trading day is conventionally defined as ending at 5pm New York time, and that moment is when most brokers apply rollover. Because New York observes daylight saving time, the server clock equivalent shifts twice a year, while many broker servers follow a fixed offset or their own seasonal schedule.
This creates a recurring source of confusion. For a few weeks around the clock changes in the United States and Europe, which occur on different dates, the gap between server time and New York time may differ from the usual pattern. Rollover may then appear to occur one hour earlier or later on the platform.
Market microstructure around this window is distinctive. Liquidity providers adjust quotes, depth thins, and spreads often widen noticeably for a few minutes. Some brokers also pause or restrict order execution briefly during the transition.
For scalpers, the implications are practical. Entries placed near rollover can face unusually wide spreads, and stop orders may trigger on a spread spike rather than a genuine price move. It is worth checking the broker's published rollover time, confirming how daylight saving changes are handled, and observing the typical spread behavior through that window before trading it.
