What Is a Prop Firm? How Funded Accounts Actually Work

A prop firm (short for proprietary trading firm) gives traders access to a bigger account than they'd usually have, as long as they stick to the firm's rules. You normally pay a fee up front, prove you can trade within the limits, and then share any profits with the firm. That's the whole idea. The details are where it gets interesting, and where most people get caught out.

This article explains how the model works in general. Every firm sets its own numbers, so treat everything below as a description of the industry, not the terms of any one provider.

What a Prop Firm Is

Traditional prop firms hired traders and gave them the firm's own money to trade. The retail prop firms you see advertised today mostly work differently. Anyone can sign up online, pay a fee and try to earn a "funded account". The firm makes money from those fees and from its share of the profits of traders who succeed.

How a Challenge Works

Most firms put you through an evaluation, usually called a challenge. You trade an account of a set size and try to reach a profit target without breaking any of the rules. Some firms use one phase, some use two, and a few skip the evaluation altogether. If you pass, you move to a funded account. If you break a rule, the account is usually closed and you lose the fee.

The Numbers on a Typical Challenge

To make this concrete, take a made-up $10,000 challenge. The percentages are in a range you'll often see, but they're not any particular firm's rules. On this account you'd need to make $800 to pass, without ever losing $500 in a single day or $1,000 in total.

Look at how close those numbers are. The room you have to lose is only a little bigger than the profit you need to make. That's by design, and it's the reason position size matters so much more on a challenge than people expect. If you trade gold at around 4,000, a 0.10 lot position moves about $10 for every $1 the price moves. A $50 move against you at that size costs $500, which would be the whole daily limit in this example.

Payouts and Profit Split

Once you're funded, profits are shared. The trader's share is called the profit split. It's normally the bigger share, but the exact percentage, how often you can withdraw and what you have to do first all vary by firm. Some ask for a minimum number of trading days before your first payout. Some have a minimum payout amount.

Simulated vs Live Capital

This is the part I wish more people asked about before paying. A lot of retail prop firms run challenges, and often the funded stage too, on a simulated account. Your trades don't go into the real market. The firm pays you based on the results of that simulated account, under its own rules. Other firms put traders on live accounts at some point. Neither is automatically a scam, but they're different products, and you should know which one you're buying.

Who Prop Firms Suit (and Who They Don't)

My honest view is that a prop firm won't fix a trading process that isn't working. It adds rules and a clock to whatever you already do. If what you already do is solid, that can be a fair deal. If it isn't, the fee usually ends up being the cost of finding out.
