Prop firm rules explained (beginner edition)

Every prop firm has the same five or six rules, dressed up with different names. Once you understand the underlying mechanics, you can read any firm's rulebook in 60 seconds. This is that foundation.

The 6 rules every firm has

1. Daily loss limit
2. Max drawdown (overall loss limit)
3. Profit target
4. Minimum trading days
5. Consistency rule
6. News / weekend restrictions

That's it. Different firms use different numbers and different names, but the structure is universal.

1. Daily loss limit

The maximum you can lose in any single trading day. Typically 4-5% of starting balance on forex prop firms, or a fixed dollar amount on futures firms (Apex $50k account: $2,500 daily loss limit, etc).

If you breach it: account dies. Immediately. No appeals, no second chances. The day either resets at midnight (most firms) or at the broker's session close (some firms).

Why it exists: stops blow-up trades. The firm's worst case on any single day is capped at this amount.

How traders break it: revenge trading after morning losses. You're down 2%, you take a bigger position to make it back, you're down 4%, you tilt, you breach 5%. Account dies.

2. Max drawdown

The total amount you can be down from your starting balance (or from your peak, depending on the firm's model). Usually 8-12% of starting balance for forex, or a fixed dollar amount for futures.

This is your overall life-of-account loss cap. You can hit your daily limit a couple times and survive; you cannot survive hitting max drawdown.

Static vs trailing drawdown

This is the big distinction:

• Static: max drawdown is always calculated from starting balance. If you start with $100k and max drawdown is 10%, your floor is $90k for the life of the account.
• Trailing: max drawdown follows your equity UP. If you start with $100k and grow to $110k, your floor moves to $99k (10% below peak). Some firms then "lock" the floor at a threshold.

Trailing is more forgiving early, much more punishing once you're in profit. Most futures firms use trailing. Most forex firms use static. Read carefully.

3. Profit target

How much profit you need to make to pass the evaluation phase(s) and get funded. Standard ranges:

• Forex two-step (FTMO-style): Phase 1 = 10%, Phase 2 = 5%.
• Forex single-step: 8-10%.
• Futures single-step: $3k profit on a $50k account is typical (6%).

Some firms time-box this (30 days to hit the target). Others don't. No-time-limit evaluations are objectively better — they let you wait for setups instead of chasing.

4. Minimum trading days

You must trade on at least X days to pass. Typically 4-10 days. Exists to prevent someone from going 1 yolo trade for 10% and "passing." Forces the firm to see some sample of your actual trading behavior.

This rule almost never matters in practice — if you're trading consistently you'll hit it naturally. Only matters if you've got an unusual style (one-trade-per-week swing trading).

5. Consistency rule

The most-misunderstood rule. Usually phrased as: "no single trading day can be more than X% of your total profit." Common values: 30%, 40%, 50%.

Example: 30% consistency rule, you've made $10k total. No single day in that history can have made more than $3k. If one day made $5k, you can't withdraw until your other days bring your total profit higher so $5k becomes less than 30% of total.

Why it exists: stops firms from paying out "lucky one-day gambles" before traders blow up. Forces a more spread distribution of profits.

Why traders hate it: it can lock up your withdrawal for weeks after a particularly good day.

6. News and weekend restrictions

Most firms restrict trading during high-impact news events (NFP, FOMC, CPI, ECB rate decisions). Some restrict holding positions over the weekend. Some are restrictive on funded accounts but relaxed on evaluations.

Why: news events create gap risk that can blow past stops. Weekend holds create gap-down risk on Sunday open. The firm caps its risk by capping yours.

How to comply: set calendar alerts for high-impact news in your timezone. Close all positions 5 minutes before. Don't reopen until 15 minutes after.

The hidden 7th rule: scaling

Once funded, most firms have scaling rules — you can grow your account size by meeting certain conditions (consecutive profitable months, accumulated profit thresholds). Each firm's scaling plan is different and significantly affects long-term earnings.

Examples:

• FTMO: 25% account size increase every 4 months if profitable.
• Apex: Can hold up to 20 funded accounts simultaneously.
• Topstep: Scaling tied to consistency + profit milestones.

Scaling matters if you plan to make prop firm trading a real income stream. For one-eval-just-to-try, ignore it.

Rule changes happen. Track them.

Firms change rules. Sometimes a lot. Topstep added then removed then re-added the daily loss reset rule over a 12-month period in 2024. FTMO tightened consistency rules in early 2025. Apex changed trailing drawdown thresholds twice in 2025.

When rules change in a trader-friendly direction (longer windows, looser news rules, higher profit splits), that's an operational health signal. When they change in a firm-friendly direction (stricter limits, tighter consistency, reduced splits), that's a stress signal.

Our firm pages note recent rule changes as we spot them. If something significant happens, we update the firm's score and the notes section.

The takeaway

Every prop firm rulebook decomposes into these 6-7 rules. Once you've internalized the structure, you can evaluate any new firm in 5 minutes. The questions are always: what are the loss limits, how is drawdown calculated, what's the profit target, what's the consistency rule, what's news policy, what's the scaling plan.

Don't pick a firm whose rules you can't articulate from memory by the time you pay for the evaluation. That's how surprise rule violations happen.
