Prop Firm Weekend and Overnight Holding Rules Explained

Can you hold positions overnight on a prop firm? Can you hold through the weekend? The short answer to both is almost always no. But the exact rules — flatten times, auto-liquidation mechanics, and the rare exceptions — vary by firm and can catch you off guard if you’re not paying attention.

The standard: no overnight, no weekend

The majority of futures prop firms require you to flatten (close all positions) before the daily session ends. Here’s why:

Futures markets close briefly each day (4:00-5:00 PM CT for CME products). During this gap, news can break, global markets can move, and when futures reopen, prices can gap significantly from where they closed. A gap against your position could breach the drawdown limit before you have a chance to react.

For the same reason but amplified, weekend holding is almost universally prohibited. Friday close to Sunday open is roughly 47 hours of potential news flow with no ability to manage positions.

Prop firms bear the risk of drawdown breaches (even on simulated accounts, the payout obligations are real), so they eliminate overnight and weekend gap risk entirely.

Flatten times by firm

*TradeDay allows holding overnight within the same trading session. A session runs from 5:00 PM CT market open through the next day’s close. You can open a position at 6 PM, hold through the night, and close the next afternoon. But you must be flat before the session close. TradeDayX Live traders must flatten by 3:00 PM CT (Plus500 clearing broker requirement).

What happens if you don’t flatten

Most firms have auto-liquidation systems that close your positions at the flatten time. The execution is not favorable — auto-liquidation uses market orders, which means you get whatever price is available. During low-liquidity periods near the close, spreads can widen and fills can be bad.

Worse, some firms treat failure to flatten as a rule violation. Repeatedly holding past the deadline can trigger account review or termination, even if the auto-liquidation prevented an actual overnight hold.

Best practice: close your own positions at least 5-10 minutes before the firm’s flatten time. Don’t rely on auto-liquidation. You’ll get better fills managing the close yourself.

Why Topstep’s close time matters

Topstep’s 3:10 PM CT deadline is the earliest among major firms. That’s 4:10 PM ET — nearly an hour before the actual futures session close (4:00 PM CT / 5:00 PM ET).

This eliminates the entire final hour of trading. The 3:00-4:00 PM CT window often sees increased volume as institutions close positions. Traders who specialize in end-of-day reversions or the “power hour” cannot execute those strategies on Topstep.

Apex’s 4:59 PM ET close gives you until nearly the actual session end. MFF at 4:10 PM EST is in between. This might seem like a minor detail, but losing the final 50 minutes of a trading session adds up over hundreds of days.

Firms that do allow overnight holding

These are rare in futures prop trading, but they exist:

• TradeDay: Within-session overnight holds allowed. Open at 6 PM, hold through the night, close the next day. Cannot hold through the daily close-to-open gap (3:50 PM CT to 5:00 PM CT). Important: auto-liquidation 2 minutes before Tier 1 economic data releases, reopens 2 minutes after.
• Elite Trader Funding: Allows overnight holding with trader-friendly conditions.
• Phidias Prop Firm: Currently the only major firm allowing both overnight AND weekend positions. This is genuinely unique in the industry.
• BluSky Trading: Supports overnight holding for funded traders.
• FundingTicks: Flexible overnight holding across multiple account types.

If overnight or weekend holding is essential to your strategy (swing trading, position trading, holding through news events), Phidias is the only option that gives you full flexibility. TradeDay’s within-session overnight is a partial solution. Everyone else requires intraday only.

How this affects your trading strategy

If you’re a pure day trader (9:30 AM – 12:00 PM): The flatten time doesn’t affect you. You’re done trading hours before any deadline. Pick your firm based on other factors.

If you trade the afternoon session (1:00 – 4:00 PM): Avoid Topstep (3:10 PM CT close). Apex (4:59 PM ET), MFF (4:10 PM EST), and TradeDay (3:50 PM CT) give you more time in the afternoon.

If you’re an overnight/Asian session trader: TradeDay is your best option among major firms. Their session runs from 5:00 PM CT, so you can trade the Asian and European sessions overnight and close the next afternoon. On every other major firm, you’d need to flatten before the US session close and re-enter after the globex open — adding transaction costs and breaking your position continuity.

If you swing trade (multi-day holds): Prop firms generally don’t work for swing trading. The no-overnight rule forces you to close positions daily, which contradicts the entire swing trading approach. Consider Phidias if you need to hold multi-day, or accept that prop firm accounts will always be intraday vehicles for you.

Friday specifics

Friday flatten rules are the same as daily rules at most firms. There is no special Friday deadline at Apex, Topstep, MFF, or Bulenox — you just need to be flat by the normal daily close time.

MFF specifically notes that overnight holds are allowed Monday-Thursday but you must flatten by Friday close. This is the most common pattern: no weekend risk, period.

Holiday schedules follow the CME calendar. Abbreviated trading hours on holidays mean earlier flatten times. Check CME’s calendar before trading on half-days — some firms auto-liquidate based on abbreviated schedules that might catch you off guard.

The bottom line: if you trade futures on a prop firm, trade it as a day trading account. Flat by session end, every day, no exceptions. The handful of firms that allow overnight holding are the exception, not the rule.
