A prop firm evaluation looks simple enough, you hit the profit target and you get funded, but in practice most evaluations are lost to the rules rather than the market. In this guide I'll break down the rules that actually decide whether you pass, using real examples from my own 23-day public Gold Futures challenge.

Every firm does things a little differently and the rules change often, so always read your firm's current rulebook, but the structure below is common across most futures prop firms.

What a prop firm evaluation actually is

You pay a fee to trade a simulated account under a fixed set of rules, and if you reach the profit target without breaking any of them you move on to a funded account where payouts become possible. Break just one rule though, and the account is closed no matter how close you were to the target.

An evaluation doesn't test whether you can make money, it tests whether you can make money inside the rules. Most of the accounts I failed during the challenge were rule failures, not strategy failures.

The profit target

Every evaluation has a profit target, often 6% of the account size, so on a $50k account that's $3,000 in profit.

The target is the easiest rule to understand and it's the one traders focus on the most, but it's also the rule that pushes people into breaking all the others. When passing becomes the goal every loss feels like a step backwards, and that urge to win it back quickly is exactly how accounts get blown.

The daily loss limit

A daily loss limit caps how much you can lose in a single trading day, so once you hit it you're done for the day, and at some firms breaching it fails the account outright.

How to use it: treat the daily limit as a budget rather than a target. Decide how many trades (or bullets) you want available and divide it up, so if your daily limit is the equivalent of 3R you can take three full-risk trades. Put all of it on one trade though, and a single loss ends your day before the better setup even shows up.

This happened to me more than once. On Day 16 and Day 22 I put the whole day's risk into the first trade, both of them lost, and both times the exact same setup appeared again within the hour and worked.

Trailing drawdown (the maximum loss limit)

This is the rule that catches most new prop traders out, because instead of sitting at a fixed floor the maximum loss limit trails your account balance as it grows.

For example, a $50k account with a $2,000 trailing drawdown starts with a floor of $48,000, and if you make $1,000 that floor moves up to $49,000. Give that $1,000 back and your balance is sitting at $50,000 again, but the floor stays at $49,000, so you now only have $1,000 of room instead of $2,000. Profit you give back still counts against you.

There are two common versions:

• End-of-day trailing: the floor only moves based on your balance at the close of each session, so open profit during the day doesn't move it.

• Intraday (real-time) trailing: the floor follows your highest unrealised balance including open profit, which means a trade that runs up and comes back can raise your floor even if you close it at breakeven.

At a lot of firms the trailing stops once the floor reaches your starting balance, and from then on it's fixed.

Why it matters: giving back profit is far more dangerous than it looks. On Day 8 I oversized trying to pass quickly, and after the loss the end-of-day trailing drawdown left me with about 1% of room, then one emotional session later on Day 9 the accounts were gone.

Consistency rules

Some firms want proof that you didn't just pass on one lucky day, so a consistency rule limits how much of your total profit can come from a single day, often around 50%.

For example with a 50% rule, if your best day is $2,000 you need at least $4,000 in total profit before that day stops breaking the rule, so the target has effectively moved.

That means a huge day can actually make passing harder, not easier. On Day 4 I closed a winner earlier than I normally would, partly because any more profit that day would've made the consistency requirement harder to meet.

Firms also apply consistency rules at different stages, with some using them during the evaluation and others only when you request a payout.

Other rules to check before your first trade

• Maximum contract size, which often scales up as you profit

• Minimum number of trading days

• Restrictions around major news releases

• The time your positions need to be closed by each session

• Which products you can trade, such as micro or mini contracts

How to trade inside the rules

After 23 days of a public challenge, the trades that broke my evaluations weren't bad setups, they were good or average setups traded with the wrong size, or taken straight after a loss or a missed trade. These are the rules I trade by now:

1. Measure everything in R. Fix your risk per trade as a fraction of the daily limit and track your results in R, so the account size never changes the maths. The cumulative R chart on the home page tracks my whole challenge this way.

2. Keep at least two or three bullets. Never risk your full daily limit on one trade, because the next setup might be the one that works.

3. Know your trailing room. Check how far you are from the floor before every session, and cut your size when that room starts to shrink.

4. Have a reset routine. After a loss or a missed trade, step away from the charts before you take another entry. The recovery protocol I built is in my Day 12 report.

5. Stop trying to pass fast. Every time I tried to pass in one or two days I failed the account, so it's process first and target second.

FAQ

Can you fail a prop firm evaluation without losing the full drawdown from your starting balance?

Yes. Because the drawdown trails your highest balance, you can fail after giving back profit even though you never lost the full limit from where you started.

What's the difference between a daily loss limit and a maximum loss limit?

The daily loss limit resets each session and caps how much you can lose in a single day, while the maximum loss limit (usually trailing) covers the life of the account. Breach the maximum loss limit and the evaluation is over.

How much should I risk per trade on an evaluation?

There's no single right number, but a common approach is to size each trade so that two or three full losses fit inside your daily limit, and so a full losing day still leaves plenty of room above the trailing floor.

Is end-of-day or intraday trailing drawdown better?

End-of-day trailing is generally more forgiving if you like to hold your winners, because open profit during the day doesn't move the floor.
