Prop Trading

Why A-Book is a Must for Your Prop Firm

Learn how the A-Book model secures financial stability for prop firms by executing trades in the real market. Amun Consulting helps you implement sustainable strategies for long-term success.

Prop firms thrive by offering traders a clear path: start with a challenge, earn a funded account, and withdraw profits from successful live trading. However, your firm’s long-term success depends on how those live trades are managed.

Here’s the difference between A-Book and B-Book models:

B-Book Only:


In this model, the prop firm acts as the counterparty to live traders. If traders make significant profits and withdraw them, the payouts must come directly from the firm’s funds. This creates a risky dependency on company reserves, threatening the firm’s stability.

A-Book:

With an A-Book model, trades from live traders are executed on the real market. Even if traders generate large profits, the prop firm remains unaffected financially because those profits were made in the market.

💡 Why A-Book Matters

✅ Financial Stability: No dependency on company funds for payouts.


✅ Sustainability: The firm can handle high-performing traders without risking collapse.


✅ Trust: Builds credibility with traders who know their trades are executed in the real market.

Relying solely on B-Book is a gamble on how long your prop firm will survive. Implementing an A-Book strategy ensures stability and prepares your business for long-term success.
