Futures prop rules: trailing drawdown, consistency and contract limits

Module 1F: Futures Foundations · Lesson 10 of 13 · Back to Futures Foundations · Course

What you’ll learn

• static vs trailing drawdown
• intraday trailing vs end-of-day trailing
• when a trailing drawdown usually stops
• how consistency rules work
• contract limits and news rules

These are the general types of rule you’ll meet at futures prop firms. The exact versions differ between firms and change often – always read the firm’s current rules page. All figures below are hypothetical.

Static vs trailing drawdown

• Static drawdown – a fixed floor. On a $50,000 account with a $2,000 static drawdown, you fail if the balance hits $48,000. Make $3,000 and the floor stays at $48,000.
• Trailing drawdown – the floor moves up as your account reaches new highs. With a $2,000 trailing drawdown, if your account peaks at $51,500, the floor rises to $49,500.

Most futures prop firms use some form of trailing drawdown. It’s the rule that ends the most accounts.

Intraday trailing vs end-of-day trailing

• Intraday (real-time) trailing follows your highest unrealised balance, including open profit. If a trade is up $800 and then comes back to break-even, your floor has still moved up $800. You can be “losing” drawdown on a trade that closed at zero.
• End-of-day trailing only moves the floor based on your balance at the close of each trading day. Open profit during the day doesn’t move it.

Worked example: the open-profit trap (intraday trailing)

$50,000 account, $2,000 intraday trailing drawdown. Floor starts at $48,000.

1. You buy 4 MES. The trade goes 40 points in your favour: open profit 40 × $5 × 4 = $800. Peak balance $50,800, so the floor moves to $48,800.
2. Price reverses and you close at break-even. Balance $50,000 – but the floor stays at $48,800. You now have only $1,200 of room, not $2,000.

That’s why many futures prop traders take partial profits, use smaller size, or avoid letting big winners turn round under intraday trailing rules.

When the drawdown stops trailing

At many firms the trailing drawdown stops moving once the floor reaches a set level – often the starting balance or a little above it. After that, it behaves like a static floor. Check exactly when and where it locks at your firm.

Daily loss limits

Some futures firms also set a daily loss limit. Hitting it may close the account or just stop you trading for the day. The “day” usually resets at a fixed US time – see 1F.6 for the UK equivalent. Even if your firm doesn’t have one, set your own (see daily and weekly loss limits).

Consistency rules

A consistency rule limits how much of your total profit can come from one day. For example, with a hypothetical 40% rule, if your best day made $1,200 your total profit must be at least $3,000 before you pass or get paid. It stops people passing with one lucky trade. Some firms apply it in the evaluation, some only in the funded stage, some not at all.

Contract limits and scaling

Accounts have a maximum number of contracts, and some firms start you on fewer until you’ve built a profit cushion (“scaling”). Micros are often counted at a ratio to minis. The limit is a maximum, not a target – see 1F.8.

News, overnight and other rules

• News rules – some firms ban holding positions through major data releases.
• Overnight and weekend rules – many futures firms require you to be flat before the daily close.
• Banned strategies – rules on copy trading, hedging across accounts, or automated systems.
• Minimum trading days – a set number of days before you can pass or request a payout.

Breaking any rule can close the account or void a payout, even if you’re in profit.

Key takeaways

• Trailing drawdown moves up with new highs; it ends the most accounts.
• Intraday trailing counts open profit; end-of-day trailing only counts closing balances.
• Many trailing drawdowns lock once the floor reaches a set level.
• Consistency rules cap how much profit can come from one day.
• Contract limits are maximums, not targets. Rules vary and change – check the firm.

Quick check

1. $50,000 account, $2,000 trailing drawdown. Your balance peaks at $50,900. Where is the floor?
2. Under intraday trailing, does an open profit you give back still move the floor?
3. With a 50% consistency rule and a best day of $1,000, what total profit do you need?

Answers: 1) $48,900. 2) Yes. 3) At least $2,000.

FAQs

Which drawdown type is easier?
End-of-day trailing is usually more forgiving than intraday trailing, and static is simplest of all. But firms balance this with other rules and prices.

Can a firm change the rules after I buy?
Some firms reserve the right to change rules. Read the terms, and keep screenshots of the rules when you buy.

Futures, spread bets and CFDs are complex and carry a high risk of losing money quickly because of leverage, and most retail traders lose money. With a real futures account, losses can exceed your deposit. Prop firm challenges are paid evaluations: the fee is usually lost, and funded accounts are usually simulated.
