Prop firm stands for proprietary trading firm - "proprietary" because the firm trades its own capital (its proprietary capital) rather than managing money for outside clients. That is the whole meaning: if a firm pools your money with other investors' and charges for managing it, it is a fund; if it risks its own capital and shares profits with the trader who generates them, it is a prop firm.

The meaning has drifted. On a 1990s bank trading floor, prop desks were salaried employees trading house money. The retail prop firm of today keeps the capital-and-split idea but replaces the hiring process with a paid evaluation: anyone can attempt the challenge, and the fee, not a salary, is the firm's filter.

Why it matters: the term is used loosely in marketing. A "prop firm" that never evaluates you and simply sells an account is an instant-funding firm - a different risk model with different rules, covered in our instant funding definition. The full history and mechanics: what a prop firm is.

The shift from bank desks to evaluations mirrors the wider retail-market history documented by the ESMA investor corner.

Frequently Asked Questions

Why is a 50% drawdown harder to recover than a 10% one?

A 50% drawdown requires a 100% gain to recover, while a 10% drawdown only needs 11.1%. Recovery math is exponential. At 30% drawdown you need 42.9% to break even. This is why prop firms cap drawdown at 10-12% rather than higher percentages.

What is the 3-5-7 rule in forex?

The 3-5-7 rule suggests risking 1-3% per trade, keeping total open risk at 5% or less, and limiting single market exposure to 7%. It is a general risk guideline, not a prop firm rule, but following it naturally keeps you within most max drawdown limits.

What is a good maximum drawdown?

For prop firm trading, keeping your actual drawdown under 5% is excellent. Most firms allow 10-12%, but staying well below the limit demonstrates strong risk management and gives you a buffer for unexpected market events.

Is maximum drawdown calculated on balance or equity?

It depends on the firm and drawdown type. Static drawdown is typically calculated on starting balance. Trailing drawdown follows your highest equity. Some firms include floating losses in their calculation, making equity the relevant measure.

What happens when you breach maximum drawdown?

Breaching maximum drawdown results in immediate and permanent account closure. All positions are closed automatically, the challenge is terminated, and there is no refund or appeal. It is the final rule with no second chances.

What is the difference between daily drawdown and maximum drawdown?

Daily drawdown resets every day and limits your loss within a single session. Maximum drawdown is cumulative across the entire challenge or funded period. You can breach max drawdown through many small daily losses that accumulate over time.
