How Proprietary Trading Firms (Prop Firms) Work

A proprietary trading firm, commonly known as a prop firm, is a company that provides traders with access to the firm’s capital instead of requiring them to trade using large personal funds. Rather than investing money into the firm, traders are evaluated on their ability to trade responsibly, manage risk, and remain consistent over time.

The process usually begins with an evaluation or challenge phase. During this stage, traders trade on a simulated account while following strict risk management rules. These rules often include a profit target that must be reached, a maximum daily loss limit, and an overall drawdown limit. The goal of the evaluation is not aggressive trading, but consistency and discipline. Breaking any of the rules typically results in failing the challenge.

Risk management is the core focus of prop firms. Common rules include limits on how much can be lost in a single day, how much can be lost overall, and restrictions on over-leveraging. Some firms may also limit trading during high-impact news events or restrict holding trades overnight. These rules are designed to protect the firm’s capital and ensure traders operate responsibly.

Once a trader successfully passes the evaluation, they receive a funded account. The capital in this account belongs to the prop firm, and the trader is allowed to manage it under the same risk rules. At this stage, the trader earns a percentage of the profits they generate, known as a profit split. Typical profit splits range from 70% to 80% in favor of the trader, depending on the firm and performance history.

Many prop firms also offer scaling plans. Traders who show consistency over time may receive access to larger account sizes, increasing their potential earnings without requiring additional personal capital. This rewards long-term discipline rather than short-term gains.

Prop firms usually charge a one-time evaluation fee. This fee covers access to the trading platform
