Been watching some pairs that move during after-hours sessions and wondering if this actually impacts where they open the next day.
Seems like sometimes the gap gets filled immediately at open, other times it holds.
After-hours moves definitely affect opening prices, but it depends on what’s happening overnight in other sessions. Since forex never closes - when one session ends, Sydney and Tokyo pick up - price discovery keeps going 24/7. You’ll see gaps when big news hits during low liquidity periods. Small after-hours moves? They usually don’t matter much. Volume’s the key here. Light movements often flip at the open, but strong moves with news behind them tend to stick around.
Overnight moves do affect opening prices, mostly when there’s good volume. If gaps fill quickly, the after-hours action might just be noise. However, if it’s driven by significant news or data, the new level often holds.
Gaps happen but they get filled fast most times.
