Weekend holding is one of those rules that traders only discover on a Sunday night, when their profitable position gaps against them and the platform opens with the account already in breach.
The three policies you will encounter
| Policy | What it allows | Who it suits |
|---|---|---|
| Full weekend holding | Positions stay open from Friday close to Monday open | Swing traders |
| Partial | Allowed on some instruments or account tiers only | Needs reading the annex |
| Flat by Friday | All positions closed before the weekly close | Intraday traders only |
Partial policies are the dangerous ones. A firm might allow weekend holding on FX majors but not on indices, or on standard accounts but not on scaled ones. Traders who upgrade and assume permissions travel with them are the ones who lose accounts.
Why the rule exists: gap risk
A stop-loss is an instruction, not a guarantee. When the market reopens after a weekend, price can open far beyond your stop, and the fill is at the first available price. A 0.5% planned risk becomes whatever the gap decides.
For a firm underwriting simulated capital, an unhedgeable weekend gap is the worst exposure it can carry, because no amount of intraday risk control helps. That is why firms either forbid the holding, reduce leverage into the weekend, or require the position to be inside a small fraction of the drawdown.
It is worth being concrete about the size of the risk. A weekend gap of 1% on EUR/USD is unremarkable in a headline-driven month. On a 2-lot position that is $2,000 on a $100,000 account. A 3% gap on an index CFD is a 3% account loss before you can press anything.
Overnight financing and swaps on simulated accounts
Real brokers charge swap on positions held overnight, and prop firms usually mirror it, deducting a financing charge from your balance at the daily rollover. Three details matter:
- Rollover time is normally the firm’s server time, often 00:00 server, which may be 22:00 or 23:00 in your local time zone. A trade closed at 21:59 local may already have been charged.
- Wednesday triple swap is standard practice. Holding over Wednesday night can cost three days of financing in one hit.
- Some firms charge financing on notional exposure, so a large lot size with a wide stop pays far more than the risk suggests. A 0.5% risk with a 200-pip stop needs a large position to be worth it, and the swap scales with that position.
Financing rarely kills an account by itself. It does quietly convert a break-even swing strategy into a losing one, which is why backtests without swap costs are misleading.
The Monday gap checklist
- Know your firm’s weekly cut-off time in server time, and confirm whether it is the Friday close or an earlier administrative cut-off.
- Check for scheduled weekend news: central bank weekends, election results, and geopolitical events. If something is scheduled, be flat.
- Reduce size rather than skipping the trade. Half size into the weekend keeps the thesis and halves the gap damage.
- Make sure the stop is inside your remaining drawdown room. If a gap of twice your stop distance would breach the account, the position is too big.
- Check whether protective stops are honoured on the reopen, or whether the firm closes positions at market. Some firms liquidate at the open if the gap breaches drawdown, which is worse than being stopped out.
- Screenshot the account state on Friday and again at the Monday open. If a dispute arises, the timestamps matter.
How this changes a swing strategy
If your edge requires holding through weekends, the firm list shrinks fast. Choose one that explicitly allows it, on the account type you are buying, and check the leverage applied to weekend positions. Then stress the strategy against historical weekend gaps on the instruments you trade: the largest overnight move of the last two years is a reasonable worst case to size against.
If your edge is intraday, the rule costs you nothing and removes a tail risk. That is not a small advantage. The risk of ruin calculator prices the difference: the same strategy with a weekend gap tail shows a materially higher failure probability over twelve months, even when the average return is unchanged.
For a practical middle route, size positions so that a gap of twice your stop distance is survivable within your drawdown. That converts the weekend from a binary account risk into a normal cost of doing business, and it lets you keep the sleep you were going to lose anyway.
