A proprietary trading firm, or prop firm, uses its own capital, trading technology and risk controls to make money from market activity.

The term "prop trading firm" now covers 2 different business models:

  1. Traditional proprietary trading firms, where professional traders execute live trades with the firm's capital.
  2. Online funded trader firms, where individuals usually pay for an evaluation, trade a simulated account and may receive payouts if they meet the firm's rules.

This article reflects firm terms and regulatory guidance available on. An online firm might advertise a $100,000 account, but that balance may be notional rather than cash available for withdrawal.

These two models are related, but they do not work in the same way.

What Is a Traditional Proprietary Trading Firm?

A traditional prop firm trades the firm's own money instead of taking deposits from retail customers. It may employ traders, provide trading infrastructure and assign each trader specific risk limits.

The trader looks for trading opportunities and executes orders. The firm controls the overall portfolio and decides how much capital and risk each trader receives. Traditional prop firms may trade through brokers, exchanges or electronic trading systems.

CME Group describes prop shops as firms that profit directly from traders' market activity and provide capital, education and trading resources.

A traditional prop trader may receive:

  • A base salary
  • A performance bonus
  • A percentage of trading profits
  • Access to research, software and market data
  • Education or training
  • A defined trading limit or risk allocation

The trader does not own the firm's capital. The trader must follow the firm's risk policy, which may include maximum daily losses, position limits, stop-loss requirements and restrictions on particular strategies.

A trader who repeatedly loses money may have their allocation reduced or their access removed.

How Does an Online Funded Trader Firm Work?

An online funded trader firm usually takes a trader through a paid evaluation before offering access to a performance or funded account.

The process often works like this:

  1. The trader chooses an account size and pays an evaluation fee.
  2. The trader receives access to a trading platform.
  3. The trader trades under a profit target and risk limits.
  4. The trader passes by meeting the objectives without breaking the rules.
  5. The trader receives access to a funded or performance account.
  6. The trader becomes eligible for payouts if the account stays profitable and compliant.

The account may still be simulated after the trader passes.

FTMO states that its evaluation and FTMO Account use fictitious capital in a simulated trading environment. FTMO may separately use data from selected traders to inform trading on its own live account, but the trader's platform account is not necessarily a live brokerage account.

Topstep describes a similar staged process for futures traders. Its program includes a Trading Combine, an Express Funded Account, payouts and, for some traders, a possible move to a Live Funded Account.

The firm's terms should state whether the account is simulated, how trading results are calculated and what conditions apply to payouts.

What Happens During the Evaluation?

The evaluation measures both trading performance and loss control.

Typical rules include:

  • Profit target
  • Maximum total drawdown
  • Maximum daily loss
  • Minimum trading days
  • Maximum position size
  • Restrictions on holding positions overnight
  • Restrictions around major economic announcements
  • Consistency requirements
  • Prohibited trading strategies

The balance shown on the platform is not the amount the trader can freely lose. A program may advertise a $100,000 account while allowing only a $5,000 or $10,000 drawdown.

For example, if a simulated account has a $100,000 balance and a 10% maximum loss, the trader's effective loss budget is $10,000. Reaching that limit can close the account even though the platform displays a much larger balance.

FTMO's published 1-Step materials list a profit target, maximum loss and maximum daily loss. The exact requirements depend on the selected product.

How Does a Prop Firm Make Money?

The answer depends on whether the firm trades live company capital or operates an online evaluation program.

Traditional Prop Firms

A traditional prop firm may earn money through:

  • Profitable trading
  • Market making
  • Arbitrage
  • Statistical or algorithmic strategies
  • Providing liquidity
  • Trading technology and infrastructure

The firm absorbs trading losses within its own risk limits. It also pays the costs of market data, software, staff, execution and other trading resources.

Online Funded Trader Firms

An online funded trader firm may receive revenue from:

  • Evaluation fees
  • Reset or retry fees
  • Trading-related subscriptions
  • Educational products and analytical tools
  • Profits from the firm's own trading
  • Aggregating or copying selected trading activity

FTMO states that its challenge fee covers the evaluation, simulated trading environment, technology and analytical tools. It also states that the company trades separately with its own capital and may use data from traders' simulated accounts.

The economics differ between firms. Their terms should explain how the company earns revenue, whether accounts are simulated and whether it can copy or use trader data.

How Are Trades Executed?

Traditional firms place live orders. Online firms often record hypothetical orders in a simulated environment.

Traditional Prop Firm Execution

In a traditional prop firm, a trader's order may be sent to a broker, exchange or other execution venue. The resulting profit or loss belongs to the firm.

Execution quality affects the result because the firm must manage:

  • Bid-ask spreads
  • Commissions
  • Slippage
  • Latency
  • Market liquidity
  • Position size
  • Order-routing costs

Online Prop Firm Execution

During an online evaluation, the trader usually works in a simulated environment using live or delayed market data, depending on the firm and platform.

The platform calculates hypothetical profit and loss from market prices. The trader may see realistic spreads, commissions and swaps, but the individual order may never reach the live market.

Some firms use trader performance data to decide which strategies to copy or trade separately with company capital. As a result, a trader may receive a payout even when their specific platform orders were never placed in the live market.

How Does the Profit Split Work?

A profit split divides an eligible payout between the trader and the firm.

For example, if a trader generates $2,000 in eligible profit and the trader's share is 80%, the trader would receive $1,600 before any applicable adjustments. The firm would retain the remaining $400.

The calculation may depend on:

  • Account type
  • Payout stage
  • Minimum payout thresholds
  • Consistency rules
  • Maximum payout limits
  • Whether losses carry forward
  • Whether the evaluation fee is refundable
  • Whether the account is simulated or live

FTMO advertises a 90% reward on certain simulated-profit accounts. Other products and firms may use different arrangements.

A profit split does not give the trader ownership of the account balance. The trader generally cannot withdraw the advertised account size. They can request payouts only under the firm's contractual conditions.

What Happens If the Trader Loses Money?

The firm normally closes, suspends or resets an account when the trader breaks a risk rule.

Common triggers include:

  • Reaching the maximum daily loss
  • Reaching the maximum overall drawdown
  • Exceeding a position limit
  • Trading during a restricted period
  • Using prohibited automated software
  • Holding positions outside permitted hours
  • Breaking a consistency or account-management rule

In a traditional prop firm, the company usually absorbs trading losses within the trader's allocated risk limit. In an online evaluation, the trader may lose the account and the fee paid for the challenge.

The trader's direct financial loss is often limited to the fees and subscriptions paid. The account can still be terminated quickly if the trader breaches a rule.

Why Do Prop Firms Impose Strict Risk Limits?

Prop firms impose risk limits to prevent excessive leverage, concentrated bets and losses that exceed the firm's tolerance.

A trader can make money overall and still fail an evaluation by losing too much in one day. The firm is testing risk-adjusted consistency, not only the final profit figure.

Risk controls also help the firm decide which traders or strategies can be scaled. A trader who makes 10% by risking nearly the entire account may be less suitable for scaling than a trader who makes 4% while maintaining stable drawdowns.

The main rules to understand are:

  1. Daily loss limit: The maximum amount the account can lose in one trading day.
  2. Maximum drawdown: The largest permitted decline from the starting balance or account high.
  3. Trailing drawdown: A loss limit that moves upward as the account reaches new highs.
  4. Position limit: The maximum number of contracts, shares or lots the trader can hold.
  5. Consistency rule: A requirement that prevents one unusually large trade from producing most of the account's profits.

Is a Prop Trading Account Really Free Capital?

No. A prop trading account is not automatically free capital.

In a traditional firm, the trader may access real company capital, but the firm controls the risk and can withdraw the allocation at any time.

In an online program, the account may contain only simulated funds. The trader receives a contractual right to request a reward based on performance, not ownership of the displayed balance.

A $50,000 or $100,000 account label does not mean the trader can withdraw that amount or risk it without consequences.

What Are the Main Advantages?

Prop trading may offer:

  • Access to larger nominal buying power
  • Lower upfront capital requirements than trading a large personal account
  • Clear risk rules
  • Performance-based payouts
  • Professional trading technology
  • A structured way to test discipline
  • The possibility of progressing from simulation to live trading

A traditional prop firm may also provide market data, software, research and a professional trading environment.

What Are the Main Disadvantages?

The main drawbacks include:

  • Strict rules that can terminate an account
  • Evaluation fees and possible retry costs
  • Simulated results that may not match live execution
  • Restrictions on trading style or holding periods
  • Unclear payout conditions at some firms
  • High leverage and rapid drawdowns
  • Limited protection if the company changes its terms or stops operating
  • No guarantee that passing an evaluation leads to a live account

The CFTC warns that hypothetical or simulated results have important limitations. It also states that futures and options trading can involve substantial risk. Traders should investigate a provider's costs, claims, registration and disciplinary history instead of relying on advertised performance alone.

What Should You Check Before Joining a Prop Firm?

Check the account model, risk rules and payout terms before paying for an evaluation.

Review:

  • Whether the account is simulated or live
  • The exact daily loss and maximum drawdown rules
  • Whether drawdown is static or trailing
  • The time used to calculate daily losses
  • Spread, commission and slippage assumptions
  • News-trading and overnight restrictions
  • Payout eligibility and processing rules
  • Profit-split percentages
  • Maximum payout limits
  • Refund conditions
  • Rules for automated trading and copy trading
  • The legal entity providing the service
  • The governing law and dispute process
  • Whether the firm explains its regulatory status

Do not judge a firm solely by its advertised account size or profit split. The practical value of the program depends on its drawdown rules, payout terms, execution model and financial stability.

The Bottom Line

A traditional prop trading firm gives traders access to company capital and earns money from live trading activity.

An online funded trader firm usually evaluates traders through a paid challenge, applies risk limits and pays eligible traders a share of simulated or live trading results.

Before joining, verify three points: whether the trades are live, how much drawdown the trader can take and the exact conditions for receiving a payout. Those details show how the firm actually works.
