Weekend Gaps (Why They Happen)
Weekend gaps happen because retail FX trading pauses after Friday’s close and resumes at the Sunday open. While you can’t trade during that window, price expectations can still change—so the first tradable quotes on Sunday can appear above or below Friday’s last price.

Forex weekend gaps
Weekend gaps happen because the market is closed to retail traders over the weekend, but the world doesn't stop. News and events can change perceived value, and the market reopens at a new price.
- Weekend Gaps (Why They Happen)
- Weekend gaps explained
- Why gaps are risky
A weekend gap is the market “catching up” to information that arrived while you couldn’t trade.
Weekend gaps explained
- What you see: the market reopens at a different price than it closed on Friday.
- Why it happens: the first Sunday quotes reflect updated expectations + order imbalance after a pause.
- Common conditions: liquidity is often thin at the Sunday open, which can mean wider spreads and jumpy pricing.
What happens over the weekend (news still moves expectations)
- Geopolitics: escalations, ceasefires, sanctions, surprise statements.
- Politics & elections: outcomes can shift risk sentiment fast.
- Central bank / emergency headlines: unexpected comments or actions can change rate expectations.
- Anything that changes “risk mood”: markets can reprice before you get a chance to react.
When trading resumes, that new information is “priced in” immediately, so the first quotes can print a gap.
Why the market can open lower (or higher) after the weekend
- Order imbalance: if weekend news is negative for a currency, more traders want to sell at the open than buy at Friday’s prices.
- Thin liquidity: with fewer orders near the last close, price may “jump” to levels where buyers and sellers match again.
- Chart effect: Friday’s close is simply the last tradable quote; Sunday’s open is the next tradable quote—sometimes far away.
Why weekend gaps are risky
A weekend gap can create slippage on stop-loss orders. That means your trade may close at the next available price, so the loss can be larger than planned.
- Stops can be skipped: price may jump over your stop level and fill worse than expected.
- Spreads can be wider: especially near the Sunday open, increasing execution risk.
