Prop firm execution

A-Book prop firms: what can you actually verify?

An A-Book broker passes client orders or market risk to an outside liquidity provider. A prop firm may use a simulated evaluation, hedge some positions, or route selected trades to a live account. These are different arrangements. Do not assume a prop firm is A-Book because its marketing mentions live capital or institutional liquidity.

Does a prop firm use A-Book execution?

There is no reliable list of A-Book prop firms based on public marketing alone. You would need evidence of where orders go, which accounts are simulated, and when the firm takes an offsetting position with a counterparty. A platform screenshot or a promise of a funded account does not establish any of that.

Ask the firm what happens during the evaluation and after you qualify. Are your orders simulated, copied to another account, or sent to an external venue? Does that treatment apply to every trader, or only to selected trades? If the answer is not documented, the execution model is unverified.

A-Book, B-Book, and hedging are not the same question

Broker terminology describes how a broker handles market exposure. A prop firm's challenge rules describe the conditions under which a trader may receive a payout. One does not prove the other. A firm can pay traders under a simulated model; another may hedge some exposure externally. Neither label alone tells you whether its payout rules are fair.

Read how prop firms make money for the business model, and what B-Booking means for the broker-side term. Treat a firm's own disclosures and agreement as the starting point, then ask for evidence when a claim matters to your decision.

What to check before paying for a challenge

  • Whether the evaluation and qualified account are simulated or live, in the firm's current written terms.
  • Whether the firm explains if or when it copies or hedges trades with an outside counterparty.
  • The actual drawdown, consistency, and payout conditions that govern your account.
  • Whether any execution claim has independent evidence, not just an affiliate page repeating it.

Our firm reviews focus on terms traders can check. Where a firm does not disclose routing, we do not call it A-Book.
