Forex trades almost around the clock during the week, but it closes over the weekend, and that pause creates gap risk. When the market reopens on Sunday evening, prices can open far from Friday's close if news broke while the market was shut. A stop loss that worked all week may not protect you in a gap, because there may be no traded price at your stop level when the market reopens. Weekend gaps are not rare events to ignore. They are a regular feature of forex, and traders who hold positions over the weekend need a plan for them.

Gaps happen because the world does not stop when forex closes. Elections, central bank comments, geopolitical events, and major economic news can all arrive on Saturday or Sunday, changing how traders value currencies before the market reopens. When trading resumes, the first available price reflects all that news at once, so price jumps from Friday's close to a new level without trading at the prices in between. Gaps are usually small, but occasionally they are large, especially on pairs involving currencies affected by weekend news. Exotic pairs and pairs with lower liquidity tend to gap more than major pairs, because fewer participants are available to absorb the initial orders.

Positions with tight stops and large size face the most gap risk, because a gap can skip past the stop and fill at a much worse price. Traders holding through the weekend with leverage are also more exposed, because a gap against them can consume a larger share of their account in a single move. Swing traders who hold for days or weeks accept gap risk as part of their strategy, but they usually use wider stops and smaller positions to compensate. Day traders who accidentally leave a position open over the weekend face the worst combination: a day-trading size and stop, held through a period it was never designed for. Always check for open positions before the Friday close, even if you think you closed everything.

The simplest way to reduce gap risk is to close positions before the weekend, especially if you are a day trader or if major weekend news is expected. If you choose to hold, reduce your position size so that even a large gap stays within your risk tolerance. Widen your stop only if you have also reduced size, because a wider stop without smaller size increases risk rather than reducing it. Some traders use options or hedges to limit gap exposure, but those tools add cost and complexity and are not suitable for beginners. At minimum, know the weekend calendar: check for elections, referendums, or major announcements scheduled for the weekend, and treat those weekends with extra caution.

If you wake up to a gap against your position, avoid the urge to act immediately in the first minutes of the Sunday open, when spreads are widest and price is most erratic. Let the market settle, check whether your stop was filled and at what price, and review whether the gap changed your original trade thesis. If the thesis is broken, close the trade according to your plan rather than hoping price returns to Friday's level. If the thesis is intact and the gap was mostly noise, you may hold, but only within your original risk limits. Record every gap event in your journal, including the pair, the gap size, and how your stop behaved. Over time, that record tells you which pairs and which weekends deserve the most caution.
