What is a prop firm?

A firm that lets you trade its capital, or a simulated account tracking it, after you pass an evaluation, in exchange for an upfront fee and a share of the profits you go on to make. The prop firm challenge is that evaluation, and this page covers how the whole model actually works before you pay to enter one.

The two things "prop firm" can mean

Traditional proprietary trading — a firm employing traders on salary, trading its own in-house capital on its own desk, no evaluation fee and no public application process — is the older meaning, and it still exists. Almost all of the search traffic behind this phrase today means something else: the modern online evaluation model, where anyone can pay a fee to attempt a challenge from home, with no employment relationship and no salary. This page is about that second, modern model, since that is what nearly every reader searching this phrase is actually asking about.

How the evaluation model works, step by step

  1. Pay the evaluation fee — priced by the size of the account you're attempting to qualify for.
  2. Phase 1 — hit a profit target while staying inside a daily loss limit and a maximum drawdown limit, usually within a maximum time window.
  3. Phase 2 (or "Verification") — many firms run a second phase with a lower profit target and the same or similar risk limits, to filter out a single lucky Phase 1 run.
  4. Funded (or simulated-funded) account — pass both phases and you're allocated a live or simulated account at the size you evaluated for.
  5. Payout — a share of profits, paid on a schedule the firm sets, often with the original evaluation fee refunded or credited on the first payout.

Where the firm's money comes from

Evaluation fees themselves are one confirmed, verifiable source of revenue — a firm running thousands of evaluations, most of which do not result in a funded payout, collects fee revenue regardless of any individual attempt's outcome. Beyond that, models differ by firm: some take a share of the spread or commission on funded-account trading, some hedge a funded account's exposure against their own book, and some combination of both is common. Exactly how any single named firm's economics work is that firm's own disclosure to make, not something to guess at here — read a specific firm's own terms if that question matters to your decision.

The five rule families you will meet everywhere

Nearly every firm's rule set is built from the same five categories, even though the exact numbers differ firm to firm:

Profit target. A percentage of the account size you must reach, usually within Phase 1 and a lower target again in Phase 2. Fail mode: running out of time or losing ground before reaching it.

Daily loss limit. A cap on how much the account can lose in a single trading day, usually measured against the balance or equity at the start of that day. Fail mode: one bad day, even inside an otherwise profitable evaluation, ends the attempt immediately.

Maximum drawdown. A ceiling on the total decline from the account's peak balance or equity across the whole evaluation, not reset daily. Static drawdown measures from the account's starting size and stays fixed; trailing drawdown moves up as the account grows, which some traders find meaningfully stricter once profits accumulate. Fail mode: a slow bleed across many days rather than one bad one.

Minimum trading days. A floor on how many separate days you must trade, designed to filter out a single oversized lucky trade passing an evaluation in one session. Fail mode: hitting the profit target too fast and having to wait out the clock anyway.

Behavioural rules. A consistency rule capping how much of total profit one single day may represent, restrictions on holding positions through scheduled news releases, and rules on holding over a weekend or overnight. Fail mode: an otherwise rule-compliant account breached on a technicality unrelated to profit or loss.

What "funded" actually means

Many funded accounts are simulated rather than live-market: your trades are tracked against real-time prices, but no order is actually routed to a real market, and the firm pays your profit split from its own funds rather than from a real position's real proceeds. This is not a secret or a scandal — it is disclosed in most firms' own terms, and a simulated funded account can pay out real money exactly as reliably as a live one, since the payout obligation is the firm's either way. What matters is knowing which kind of account you actually have, since the two carry different implications for things like maximum position size relative to real market liquidity.

What it costs

Fee tiers scale with the account size being evaluated — a larger target account costs more to attempt. Most firms treat the fee as sunk the moment you start: failing does not return it, whether you failed on day one or the day before the deadline. Resets, letting you restart an evaluation from the beginning without paying the full fee again, are a common but not universal add-on, usually at a reduced additional cost.

Who this suits and who it doesn't

The evaluation model suits someone who already has a measurable edge and demonstrated risk control from their own trading history — the challenge is a test of an existing skill, not a way to build one. It does not suit someone hoping the pressure of a funded account will produce discipline that wasn't there in their own unfunded trading first; the daily loss limit and drawdown rules apply the same pressure a trader's own risk management should already be applying voluntarily, and a rule set rarely fixes a habit the trader hasn't fixed themselves first.

Seven questions to ask before you pay

  1. Is the maximum drawdown static or trailing, and trailing based on balance or on equity?
  2. When does the daily loss limit reset, and in which timezone?
  3. Does floating (unrealised) P&L count against the daily loss limit and drawdown, or only realised, closed P&L?
  4. What is the actual payout schedule — how often, and how long after a request until funds arrive?
  5. What exactly does the consistency rule cap, and does it apply during the evaluation, the funded stage, or both?
  6. Which instruments and strategies are permitted, and are any explicitly banned?
  7. What happens immediately on a breach — is the account closed instantly, or is there a grace mechanism?

Take this list to any firm's own rules page before paying, not after.

Check your own record against a rule set first

Before paying an evaluation fee, the more useful question is whether your own existing trading, measured honestly, would already have passed the rule set you're about to pay for. Model a rule set against your own win rate before you commit a fee to finding out live, or replay your actual trading history against a specific firm's rules retroactively with the (NEW) prop firm challenge tracker — would this account have breached, and on which day? Sizing each trade correctly against a daily loss limit starts with knowing your own risk per trade, and if you already have closed trading history in MT4 or MT5, the statement analyzer works out your real drawdown and win rate from it directly rather than from a guess.

Questions

Are prop firms legit?

Many operate a real, verifiable business: fees in, evaluations run, funded or simulated-funded accounts, payouts out, all documented in the firm's own published terms. Legitimacy varies firm to firm, not across the model as a whole, which is exactly why the questions checklist below asks you to read a specific firm's own rules page rather than trust the model in general.

How much does a prop firm challenge cost?

Fee tiers scale with the account size you're evaluating for — a larger simulated account costs more to attempt. Fees are typically non-refundable if you fail, and several firms refund the fee (or credit it) once you pass and receive your first payout. Check a specific firm's own fee page rather than assuming a figure, since tiers and refund policies both vary and change.

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

A daily loss limit resets every trading day and only measures that single day's loss. Maximum drawdown accumulates across the entire evaluation or funded period and does not reset daily. An account can breach a daily loss limit on its worst single day while still being nowhere near its overall maximum drawdown limit, and vice versa — they are two separate rules, not two ways of describing the same one.

Do I need my own capital?

You need the evaluation fee, not trading capital in the traditional sense — the account you trade during the evaluation, and the funded account afterward if you pass, is capital the firm provides (or simulates providing, with real payouts drawn from firm funds; see 'what funded actually means' below). What you do need beforehand is a measurable track record and tight risk control, since the evaluation is testing exactly that.

Can I fail a challenge without losing money?

Yes. Most rule sets include at least one behavioural or timing condition — a minimum number of trading days, a consistency rule capping how much of your total profit one single day can represent, a restriction on holding positions over a weekend or through news — that can end an evaluation regardless of whether the account is profitable at the time.
