An overnight holding restriction is an evaluation rule prohibiting traders from carrying open positions past the daily market close or into the weekend. Where it applies, all positions must be closed before a defined cut-off time — typically the New York close at 17:00 ET — or the trade is treated as a rule violation.
Not all programs impose this restriction. Where it does not exist, overnight and weekend holding is permitted, and the swap cost or credit simply applies at rollover. Whether the restriction exists is a binary fact that must be confirmed in the rulebook before adopting any strategy that naturally holds positions overnight.
Why programs impose overnight restrictions
The stated rationale is gap risk: markets can open significantly higher or lower than the previous close due to news events, economic data, or geopolitical developments that occur when the market is closed. A position with a stop-loss set inside normal trading hours may gap through that level at open, resulting in a fill far beyond the intended risk — enough to breach the daily loss limit or drawdown floor on a single overnight event.
Weekend holds carry amplified gap risk because the market is closed for approximately 48 hours, during which a wide range of events can accumulate. Programs that apply overnight restrictions typically apply stricter weekend restrictions as a consequence.
Strategic implications
Strategies that are structurally incompatible with an overnight restriction include swing trading approaches that hold for multiple days, carry trade strategies that explicitly rely on swap accumulation, and any position-trading approach targeting multi-week moves. These strategies may be highly profitable in standard market conditions yet fail this specific rule regardless of performance.
Day trading strategies designed to close all positions before market close are unaffected. The restriction is neutral to intraday approaches; it specifically targets holding behaviour.
What to confirm in the rules
- The exact cut-off time and timezone — 17:00 ET is common but not universal.
- Whether the restriction covers all instruments or only specific asset classes (some programs restrict overnight on indices or crypto but permit it on forex).
- The consequence of a violation — warning, trade closure, or immediate evaluation termination.
- Whether the restriction applies differently on Friday close versus any weekday close.
