When I assess a prop trading offer, the advertised account size is not the first number I check. I look at the maximum loss and ask whether the account is live or simulated.
A $100,000 account can mean two very different things. At a traditional proprietary trading desk, it may refer to real firm capital and live market exposure. At an online funded-trader program, it may be a simulated balance with a $10,000 loss limit.
Prop trading, in its original sense, means that a company trades its own capital for its own profit. The company carries the market risk. Its traders usually work as employees, partners or contractors and receive a salary, bonus or share of trading profits.
Modern online prop firms use another model. A trader usually pays for an evaluation, trades under fixed rules and becomes eligible for rewards after meeting the firm’s conditions. The challenge is normally simulated. The later “funded” account may also be simulated, although some firms move selected traders or trades to live capital.
What is prop trading?
Proprietary trading is trading done with a firm’s own capital rather than a client’s money.
The firm keeps the gains and bears the losses. In formal market language, this is often called dealing on own account. MiFID II defines it as trading against proprietary capital that results in transactions in financial instruments.
A traditional prop trader works inside that business. An online funded program instead sells an evaluation and may pay a reward based on simulated performance.
One term, two different deals
The same “prop trading” label can describe a professional trading business or a paid evaluation program.
-
Capital
Firm money
The company puts its own balance sheet at risk.
-
Trader
Desk or team
A selected trader works inside the firm’s risk limits.
-
Execution
Live market
Orders create real positions and real market exposure.
-
Outcome
Actual P&L
The firm keeps the result and pays salary, bonus or profit share.
-
Access
Fee or subscription
The participant pays for an evaluation attempt.
-
Evaluation
Simulated challenge
Profit targets and loss rules measure performance.
-
Next stage
“Funded” account
It may remain simulated or later move to live capital.
-
Outcome
Contractual reward
Eligible simulated or live profit determines the payment.
The program agreement should state whether each stage is simulated or live.
Traditional prop firm vs online funded account
| Question | Traditional prop firm | Online funded-trader program |
|---|---|---|
| Whose capital is traded? | The firm’s real capital | Often simulated capital; live routing depends on the firm |
| What is the relationship? | Employment, partnership or contractor arrangement | Customer or contractor relationship under program terms |
| Does the trader pay to join? | Normally no; recruitment may be selective | Often yes, through an evaluation fee or subscription |
| How is the trader assessed? | Interviews, track record, training and ongoing risk review | Profit target, drawdown limits, trading days and other rules |
| How is the trader paid? | Salary, bonus or share of actual trading profit | Reward based on eligible simulated profit, or a share of live profit |
| Where do the firm’s earnings come from? | Trading P&L, market making or related activity | Fees, subscriptions and potentially the use of selected trading data or live trades |
| Main risk to the trader | Losing the role or bonus after poor performance | Losing the fee, breaching a rule or having a reward rejected under the contract |
Neither model is automatically better. They solve different problems.
A traditional desk is a job or professional trading arrangement. A funded program is a paid evaluation service that may lead to performance rewards. Calling both “prop firms” does not make their contracts interchangeable.
How does a funded trading account work?
Most retail programs follow this sequence.
1. You choose an evaluation
You select a nominal account size and pay a fee or subscription. The payment normally buys an attempt; it is not a deposit into a brokerage account.
2. You trade under evaluation rules
Common rules include:
- a profit target;
- a maximum daily loss;
- a maximum total loss;
- minimum trading days;
- a time limit, although some programs have none;
- a consistency or best-day rule;
- restrictions on news trading, overnight positions, copied trades or automated strategies.
Passing requires meeting the target while every other rule remains intact.
3. You enter the funded stage
After passing, you receive what the industry calls a funded account. It may contain live firm capital, simulated capital or a mix in which the firm decides whether to copy some trades into its own live account.
4. You become eligible for rewards
The firm calculates a reward from qualifying profits and applies the agreed split.
If the account records $4,000 of eligible profit and the trader’s share is 80%, the gross reward is:
$4,000 × 80% = $3,200
The request can still be subject to profitable-day requirements, a consistency rule, a waiting period and identity checks.
5. The account continues, resets or closes
After a reward, the account may continue, reset or move to another stage. A breach normally closes or suspends it. The contract controls the process.
Does a funded account contain real money?
Sometimes. Often it does not.
Many challenge-based programs keep both the evaluation and the funded stage in a simulated environment. Others use simulation before deciding whether to move a trader to live capital. Some route selected positions into the market without making the participant’s account live.
A firm can pay real cash while every trade remains simulated. I still want to know what funds rewards, what can cancel one, whether live capital is promised and which legal entity owes the payment. The terms matter more than the phrase “trade our capital.”
The account size is not your risk budget
This is the calculation I wish more traders made before buying a challenge.
Consider a two-step program with these example terms:
$100,000initial simulated capital;- a
10%, or$10,000, first-stage profit target; - a
5%, or$5,000, maximum daily loss; - a
10%, or$10,000, maximum total loss.
These figures make the calculation easy to follow. They are illustrative, not an industry standard.
The headline says $100,000. The distance from the starting balance to failure is $10,000.
That makes $10,000 the more useful number for risk planning.
The real account is the loss allowance
Worked example based on a two-step $100,000 simulated account with a 10% target and 10% maximum loss.
$10,000 down closes the account under the example’s total-loss rule.
$10,000 up reaches the first-stage target, provided every other rule is met.
This is a sizing example, not a recommended risk level. Daily loss, trailing drawdown, correlated positions, gaps and costs can reduce the available room.
Suppose a trader risks 2% of the advertised balance per trade:
$100,000 × 2% = $2,000
That single trade risks 20% of the entire maximum-loss allowance:
$2,000 ÷ $10,000 = 20%
Five full losses would consume the allowance before commissions, swaps or slippage. And two or three losses on the same day could threaten the daily limit.
Now size risk from the loss budget instead.
Assume the trader wants the plan to survive 12 full losing trades and keeps 20% of the maximum-loss allowance as a buffer:
$10,000 × 80% ÷ 12 = $666.67
About $667 per trade is 0.67% of the advertised balance, but 6.67% of the usable loss budget.
This does not guarantee survival. Correlated positions, gaps, costs and daily-loss rules can reduce the available room. But it uses the constraint that can end the account.
The rules that matter most
The profit split gets the attention. The drawdown formula usually decides the outcome.
Maximum daily loss
Check whether the calculation includes:
- closed losses;
- floating losses;
- commissions;
- swaps;
- positions opened before the daily reset;
- profits made earlier in the same day.
Also note the reset time and its time zone. An open position can be within the limit before the reset and breach it after the calculation starts again.
Static vs trailing drawdown
A static drawdown stays fixed. A trailing drawdown moves upward with new balance or equity highs. It may trail intraday, use end-of-day balance or stop after a threshold. Work through the firm’s formula with numbers.
Consistency rules
A firm may limit how much of total profit can come from the best day. A large win can leave the trader above target but still ineligible to pass or withdraw.
Trading restrictions
Check the rules for:
- trading around economic releases;
- holding positions overnight or over a weekend;
- expert advisers and automated trading;
- copied or coordinated trades;
- latency arbitrage and price-feed exploitation;
- maximum position size;
- inactive accounts.
“Any strategy allowed” often has exceptions several pages later.
Reward conditions
Check the first eligible request date, minimum amount, profitable-day requirements, KYC, processing time, rejection clauses and whether terms can change for an active account.
How do prop firms make money?
A traditional firm aims to earn from real trading. An online funded program may earn from:
- evaluation fees;
- recurring subscriptions;
- paid resets or activations;
- a share of eligible profits;
- trading data or selected strategies;
- live execution of selected trades.
The mix differs. Fee revenue creates a potential conflict because the firm can benefit from repeated attempts. That does not prove dishonesty, but the firm’s incentives may not match the trader’s. I prefer firms that disclose simulation and publish the full rulebook before checkout.
Can prop traders make money?
Yes, but there is no useful “average prop trader income” that covers both models.
An employed trader’s compensation is a labour-market question. An online participant’s result depends on fees paid, evaluations failed, rewards received, taxes and other costs.
I would track the second model as cash flow:
Net result = rewards received − evaluation fees − resets − subscriptions − data and platform costs
For example, suppose someone buys two $500 evaluations and later receives one $3,200 reward:
$3,200 − $1,000 = $2,200
The net cash result is $2,200 before tax. The dashboard may show more trading profit; the bank account does not. Payout screenshots also omit failed attempts and unrewarded simulated profit.
Pros and cons of funded-trader programs
| Potential benefit | What limits it |
|---|---|
| Personal market loss may be limited to the fees paid | Repeated fees and resets can still add up |
| The rules impose a defined risk boundary | A technical breach can end an otherwise profitable account |
| A trader can test discipline without funding a large brokerage account | The nominal balance may overstate the usable risk budget |
| Eligible performance can lead to cash rewards | A reward depends on the firm’s contract and ability to pay |
| Some firms offer a route to live capital | The route may be discretionary rather than guaranteed |
The model may suit a trader who already has a tested process, can follow mechanical limits and treats the fee as money that may be lost.
It is a poor fit for someone who needs quick income, depends on one large winning day, changes strategy during losses or plans to keep buying resets until one account passes.
A challenge is not trading education. It is an exam with a paid attempt.
Is prop trading legal?
There is no global yes-or-no answer.
Rules differ by jurisdiction and activity. The position can change when a firm executes client orders, manages outside money or provides investment services. A simulated evaluation may be a software or assessment service, which can leave the customer without the protections of a regulated investment account.
Regulators do not all describe the sector in the same way. Belgium’s FSMA, for example, warns consumers that many challenge-based firms use demo accounts, decide which trades to copy and control reward conditions.
Before paying, check:
- The legal name and registered address of the company.
- The law and court or arbitration forum in the agreement.
- Whether the service is simulated, live or mixed.
- Whether the activity claims regulatory authorization.
- Whether that authorization covers the service being offered.
- Which protection or complaint route applies if a reward is disputed.
A company registration is not a financial licence. A financial licence is not universal permission for every product or country.
Final thoughts
Prop trading has one clear traditional meaning: a firm trades its own capital for its own profit. The online funded-account industry added a second model built around paid evaluations, simulated accounts and performance rewards.
The most useful question is not, “How large is the funded account?”
Ask how much loss the rules allow, how that limit moves, whether the account is live and what can cancel a reward. Those four answers describe the deal better than the account size or profit split.
