Prop Firm
Also known as: proprietary trading firm, prop trading firm, funding firm, prop shop
What is it?
A prop firm - short for proprietary trading firm - is a company that puts its own capital behind traders who prove they can follow a risk rulebook, and takes a share of the resulting profit instead of charging them for the trades. The modern retail version works as a paid audition. You buy an evaluation for a fee, trade a simulated account of a stated size, and must reach a profit target without breaching a daily loss limit or a maximum drawdown.
Your own retail account vs a prop firm account
Your retail account
- Your deposit, so every dollar of loss is money you funded yourself
- No profit target and no external rulebook to satisfy
- Position size is capped by what you can afford to deposit
- You keep 100% of the profit
- One bad month costs savings, not access to the account
Full control and full downside, with size limited by your own balance.
Prop firm funded account
- The firm's capital, so a losing run costs the fee, not your savings
- Profit target, daily loss limit and maximum drawdown all apply
- Trade $100,000 of size after a roughly $500 evaluation fee
- You keep an agreed share of profit, commonly 80%
- One rule breach ends the account however profitable it was
Bigger size and capped downside, paid for with a strict rulebook.
Pass, and the firm gives you a funded account and pays you an agreed share of the profit you generate on it. Breach a rule, and you lose the fee rather than your savings. The numbers make the appeal obvious.
A $100,000 evaluation typically costs $400 to $600, asks for an 8% ($8,000) profit target, and caps you at 5% ($5,000) of loss in any single day and 10% ($10,000) of total drawdown. Clearing that target later on a funded account at an 80/20 split pays the trader $6,400 of the $8,000. What you are really buying is size you do not own, and the rulebook is the price of it.
Why it matters: A prop firm lets you trade size you do not own, but only inside a rulebook where one bad session can end the account regardless of how profitable the month was.
Trading someone else's capital means the firm's risk rules, not your own judgment, decide when a position has to be closed.
Real-world example
A trader passes a $100,000 two-step evaluation, then loses $5,200 on a single US CPI release, breaching the $5,000 daily loss limit and ending the account despite being up $3,000 for the month.
How SignalBots handles it
SignalBots signals ship with explicit entry, stop and target levels, so you can size each trade against a prop firm's daily loss limit before you take it rather than discovering the breach afterwards. See /risk-warning.
Pro tip
Read the payout terms before the profit target: a firm paying 80% but only every 30 days ties up money longer than one paying 70% every 14 days.
Common pitfalls
Treating the evaluation fee as the only cost, then re-buying failed challenges four times until the fees exceed what a funded account would have paid.
Frequently asked questions
Is a prop firm account real money?
On most retail firms the evaluation is simulated and the funded account is either simulated or a small live allocation. What is real is the payout: the firm pays your profit share in cash from its own books.
Do I risk my own money at a prop firm?
Only the evaluation fee. You cannot lose more than what you paid, because the trading capital is the firm's. That also means you have no say in the rules protecting it.
Why do prop firms charge a fee at all?
The fee covers the platform, the data feeds and the cost of funding candidates who breach immediately. For many firms it is also a large share of revenue, which is part of why the rules are strict.
Can I use a trading bot at a prop firm?
Most firms allow expert advisors and automation but ban latency arbitrage, tick scalping and copy trading across several funded accounts. Check the prohibited-strategies list before you connect anything.
How is a prop firm different from a broker?
A broker gives you market access using your own deposit. A prop firm gives you its capital and takes a cut of the profit, so it also imposes rules on how that capital may be traded.
