What is a prop firm and how does it work?

A prop firm — proprietary trading firm — is a company that gives independent traders access to trading capital in exchange for a share of the profits made. In the online model that dominates today, that access is paid for: you buy an evaluation called a challenge, where you must reach a profit target without breaching strict loss limits. Pass, and the firm opens a funded account and hands you most of the gains, usually 80 to 90 % depending on the profit split. Fail, and you lose the fee you paid and nothing more: no personal capital is exposed to the markets.

Two industries behind one word

The term covers two realities with almost nothing in common. The historic proprietary trading houses operate in the markets with their own balance sheet, hire salaried traders through a selective recruitment process, and charge their candidates nothing. You get in through an interview, not a payment, and you trade institutional infrastructure.

The second world is that of online retail prop firms, which appeared in the second half of the 2010s and have become an industry in their own right. Here nobody reads your CV: selection rests entirely on performance measured in a constrained environment, and that measurement is paid for. Firms such as FTMO and The5ers popularised the format, now offered by several hundred companies. It is that model the rest of this guide describes, and the one behind almost every search on the subject.

What you are actually buying

A challenge is not an investment, a loan, or a deposit. No capital is transferred to you at any point. You are buying a two-stage service: an assessment of your trading under constraints, then, if you pass, a contract entitling you to a fraction of the profits generated on an account the firm provides.

The distinction has practical consequences. Fees are not refundable as of right — many firms return them with the first payout, but that is a commercial clause, revocable, not a legal guarantee. You do not own the account and can never withdraw the “capital” from it, only the profits. And your right to be paid is a claim against a commercial company: it is worth exactly what that company’s solidity is worth.

The typical path, step by step

The evaluation

Phase 1 generally asks for a gain of 8 to 10 % of the nominal capital, without exceeding a daily loss of around 4 to 5 % or a total loss set between 5 and 12 % depending on the firm. A minimum number of trading days is often added, designed to weed out the trader who reaches the target in a single oversized position.

Two-phase formats add a phase 2 with a reduced target, often half the first, and the same loss limits. The stated aim is to check that the performance was not luck. Time limits, long fixed at 30 then 60 days, have largely disappeared among recent firms, replaced by minimum activity requirements.

The funded account

Once the evaluation is passed, the profit target disappears but the loss limits remain, sometimes tightened. The account runs in cycles: you trade, and at regular intervals — fourteen days, sometimes less — you request a payout. The profit split comes to you and the firm keeps the rest. Many offer a scaling plan that increases the nominal capital after several profitable cycles.

The first payout

This is the step that really counts. It involves identity verification, signing a trader agreement, sometimes producing tax documents, and a processing delay. A funded account that has never paid out is just a line in a dashboard: until the first transfer lands, you have verified nothing about the firm.

Simulated account or real capital

Most retail prop firms have their clients trade simulated accounts, including after the evaluation phase. That is not necessarily a fraud and it is generally not hidden: the terms and conditions say so, often in wording that deserves careful reading.

The arrangement has real implications. Your profits do not come from a market account identified in your name, but from a contractual calculation the firm performs against its own price feed. That means execution, slippage and spreads follow internal choices; that the firm can change its rules for new accounts, and even for existing ones depending on how the contract is written; and that your payout is paid out of company cash. Some firms do hedge their most consistent traders’ positions on the live market, which aligns their interests with yours.

Where the money paid to traders comes from

Three sources fund payouts. The first, and by far the largest at most firms, is the evaluation fees paid by all candidates — most of whom fail. The second is genuine hedging of successful traders’ flow: the firm replicates their positions in the market and collects its share of the actual gain. The third gathers ancillary revenue: resets, extensions, paid add-ons, affiliate commissions.

A firm living only off the first source depends on a continuous stream of new sign-ups. That is a fragile model, sensitive to a marketing slowdown and to a run of simultaneously winning traders.

The rules that decide the outcome

The standard of trading demanded is rarely the obstacle. It is the peripheral rules that eliminate:

• Daily drawdown: calculated on equity or on balance, intraday or at the close. An unrealised loss alone can breach an equity-based limit, even if the position later comes back into profit.
• Total drawdown, static or trailing: a trailing drawdown follows your highs and rises with gains. It makes the margin for error move, and catches out traders used to reasoning against the starting capital.
• Consistency rule: caps how much of total profit one day or one position may represent. It blocks payouts more than it fails challenges, which makes it all the more frustrating.
• Exposure restrictions: no holding positions through macro releases, over the weekend, or beyond a certain cumulative lot size.
• Prohibited methods: martingale, latency arbitrage, HFT, copy trading between accounts, management by a third party.

None of these rules is on the sales page. They are in the terms and conditions and in the FAQ, to be read before buying.

What a prop firm is not

It is not a broker, even where a firm belongs to the same group as one: you open no account in your own name and you deposit no funds. It is not third-party asset management: nobody trades on your behalf and you collect nobody’s money. It is not a job: no fixed income, no social protection, no seniority.

In regulatory terms, most of these companies hold no client funds in the financial-markets sense and therefore fall outside investment-firm authorisations. The consequence is direct: in a dispute or a failure there is no compensation scheme, and recourse is limited to the commercial law of the country of incorporation, often a distant one.

Who the model suits

The format rewards a trader who already has a stable method, a trade journal covering several months, and enough risk discipline to operate under a tight drawdown constraint. For that profile the challenge is a rational way to test a size of capital out of reach on a personal account, at a capped cost.

For a trader who is not yet consistent, it is the reverse: paying for an evaluation amounts to funding the discovery of a problem a few months of demo would have revealed for free. The right question before buying is not “which firm should I choose” but “is my system already making money, measured, over a large enough sample”.

Three checks before paying

Look at whether the firm publishes recent, verifiable payout evidence rather than screenshots alone. Read the clause describing how drawdown is calculated: that is the one that will decide your failure. And find the legal entity, its jurisdiction and its age — a company a few months old is offering you a contract whose performance will stretch over several years.
