What Is a Prop Firm Evaluation? How Combines Actually Work

A proprietary trading firm ("prop firm") gives traders access to the firm's capital instead of their own. The deal: prove you can trade profitably *within the firm's risk rules*, and the firm funds an account and splits the profits with you. The proving stage is the evaluation — Topstep calls theirs the Trading Combine, and the structure is similar across the funded-futures industry.

This guide explains the mechanics in plain English, because most first evaluations are lost to misunderstood rules, not bad trading.

The deal in one paragraph

You pay a monthly subscription for an evaluation account with simulated capital. The firm sets a profit target and a set of loss limits. Hit the target without ever breaching a limit and you advance to a funded account, where profits become real withdrawals. Breach a limit and the attempt ends — you reset or re-subscribe and start over. The firm's business depends on funding disciplined traders; the rules exist to find them.

The three numbers that define every evaluation

Using Topstep's 50K Combine as the running example (figures as published at the time of writing — always verify current parameters on the firm's own site):

1. Profit target — e.g. $3,000 on the 50K. The finish line.
2. Daily loss limit — e.g. $1,000. Lose that much in one day and the day (and often the

attempt) is over. Treat it as a circuit breaker, not a budget.

1. Trailing maximum loss — e.g. $2,000, trailing your account's high-water mark. This is

the rule that surprises almost everyone: the threshold *moves up as you profit*, so the cushion you started with is not the cushion you have after a good week. It is subtle enough that we wrote a full trailing-drawdown explainer.

The relationship between these numbers matters more than any of them alone — the account-size comparison walks through how target, daily limit, and trailing room scale across the 50K, 100K, and 150K.

The rules that are not numbers

Evaluations also carry operational rules that end attempts without a single oversized loss: flatten deadlines (Topstep requires all positions closed by 3:10 PM CT), restricted trading around major news events at some firms, minimum trading days, and consistency rules that cap how much of your profit may come from one day. Read the current rule page of the firm you are evaluating with — rules differ by firm and change over time.

What "funded" actually means

Passing does not hand you a live brokerage account with the firm's cash on day one. Most funded-futures firms fund into a staged structure (Topstep's Express Funded Account is an example) where you trade with the same discipline rules and earn real payouts, with live funding further along. The rules do not relax after funding — the payout rules add new numbers to respect, and most funded accounts are lost to the same discipline failures that end evaluations.

How to prepare for your first evaluation

• Trade the rules before you pay for them. Know the daily limit, trailing mechanics, and

flatten deadline cold. Simulate a week under those exact constraints first.

• Size from the loss limits, not the target. Pick a contract size whose normal worst day

cannot reach the daily limit — the 50K sizing guide does this arithmetic explicitly.

• Journal from day one. An evaluation is a discipline test; measure the discipline. Room

consumed per day, rules kept, planned vs actual size, one correction per session — the journal template has the columns, and Propfy tracks the Topstep rules against your live account automatically.

• Budget for more than one attempt. Most traders do not pass their first. The subscription

model means an ended attempt is tuition, not ruin — if the lesson gets journaled.

Frequently asked questions

What happens if you fail a prop firm evaluation?

The attempt ends when a loss limit or rule is breached. Depending on the firm you can usually reset the account for a fee or wait for the next subscription cycle to restart. Nothing is owed beyond the subscription — the loss capital was simulated — but the time and tuition are real, so the failure is worth journaling properly before paying again.

How long does a prop firm evaluation take?

Most futures evaluations have no maximum time — the subscription renews monthly until you pass or stop. Minimum trading-day requirements vary by firm and by account phase. Rushing is the classic failure mode: the target rewards patience, while the loss limits punish forcing.

Is prop firm money real money?

Evaluation capital is simulated. Once funded, payouts are real: you trade the firm's account under its rules and withdraw your profit share through the firm's payout process. The firm's published payout rules govern when and how much — see our Topstep payout guide for how that works there.

Are prop firm evaluations worth it?

For a trader with a tested process and the discipline to follow rules, an evaluation is cheap access to meaningful capital. For a trader still developing an edge, the subscription becomes a recurring cost of discovering that discipline is the missing piece. An honest journal is the cheapest way to find out which trader you currently are.

The evaluation is a preview

Every rule in the evaluation exists in the funded account too. The traders who pass — and stay funded — are the ones who treat the combine not as an obstacle before the real thing, but as the real thing itself: same rules, same sizing, same review, every session.
