Prop Firm Rules Explained

Prop trading firm marketing focuses on two numbers: the funded account size and the profit split. Both are close to irrelevant if you break a rule you did not understand. This hub explains the rules that actually decide whether you pass an evaluation, keep a funded account, and get paid.

Everything here is educational and not financial or trading advice. Rules and promotions change constantly — always confirm the current terms on the firm’s official website before paying for a challenge.

The rules that actually matter

Most comparison sites lead with the profit split (usually 80–90% everywhere, so it barely differentiates firms). The variables that genuinely change your odds are:

  1. Drawdown model — static, end-of-day (EOD) trailing, or intraday trailing. This single rule changes how much room you really have.
  2. Consistency rule — caps how much of your total profit can come from your best day.
  3. Profit target + minimum trading days — how far you must go, and how fast you are allowed to get there.
  4. Payout schedule — how often you can withdraw and what you must do to qualify.

Drawdown: the rule that fails most traders

Drawdown is the maximum you are allowed to lose before the account is breached. The type matters more than the number:

  • Static drawdown — a fixed floor that never moves. The most forgiving.
  • End-of-day (EOD) trailing — the loss limit follows your balance, but only updates at the market close.
  • Intraday trailing — the limit follows your highest equity in real time, including unrealised gains on open trades. The strictest, and the one that surprises people.

We break this down in detail in EOD vs trailing drawdown explained.

Consistency rules

A consistency rule stops you passing (or getting paid) on the back of one lucky day. A typical version says no single day may account for more than 30–50% of your total profit. It is one of the most misunderstood rules in the industry — see the consistency rule explained.

Payout terms

A 90% split you cannot reach is worse than an 80% split with clean terms. Check the first-payout waiting period, minimum trading days before withdrawal, and any buffer requirements before you commit.
