Exness A Book or B Book
Exness employs a hybrid execution model, integrating both A Book (agency model) and B Book (market maker model) strategies. This approach allows the broker to route trades either to external liquidity providers or manage them internally, depending on various factors such as client profile and trading behavior. By doing so, Exness aims to optimize trade execution and risk management, catering to a diverse range of trading strategies and client needs.

What Is the A Book and B Book Model?

These terms are commonly used in forex and CFD trading to describe how brokers handle client trades:

A Book (Agency Model)

  • Orders are passed to external liquidity providers
  • Broker earns from spreads or commission only
  • No direct conflict of interest with clients

B Book (Market Maker Model)

  • Broker takes the other side of the client’s trade
  • The broker profits when the client loses, and vice versa
  • Orders are filled internally

Key Differences Between A Book and B Book

Which Model Does Exness Use?

Exness follows a hybrid model, combining both A Book and B Book execution. This setup allows Exness to manage risk efficiently and offer flexible conditions to a variety of clients.

Factors That Influence Routing:
  • Client’s risk profile (e.g., traders with low drawdowns and consistent performance)
  • Historical trading behavior (e.g., over 10 standard lots/month may lean A Book)
  • Instrument volatility (e.g., high volatility may temporarily shift trades to A Book)
  • Internal risk thresholds (evaluated in real time using proprietary algorithms)

How Exness Manages Risk Using the Hybrid Model

Risk Management Methods Used by Exness

  • Algorithms to detect client trading patterns (e.g., latency arbitrage, high-frequency scalping)
  • Automatic switching between A/B book as needed (in response to trade volume and behavior)
  • Dynamic exposure hedging (e.g., offsetting B Book trades with opposite positions via liquidity providers)
  • Spread adjustments during volatile periods (temporary widening to ensure execution and protect system risk)

Transparency of Execution at Exness

While Exness does not disclose which execution model is used for each individual trade, it maintains transparency in execution quality. The broker frequently publishes performance metrics, including:
  • Average order execution time
  • Slippage statistics
  • Requote and rejection rates
These can often be found in Exness's quarterly reports or press releases. Such transparency reinforces trader trust, even when specific routing is confidential.

How to Know Which Model You’re On

Exness does not publicly label whether a client is on A Book or B Book. However, based on behavior, some indicators can help you make an educated guess.

Signs You May Be A Booked:
  • You trade consistently in large volumes
  • You use automated trading tools or EAs
  • Your risk exposure is low and steady

Signs You May Be B Booked:
  • You trade occasionally with small lot sizes
  • You hold positions for very short durations
  • You have received bonuses or promotional credits

Important: These are not guarantees but general tendencies based on industry patterns. Account type can also influence the likelihood — for example, Raw Spread accounts may more often be routed through A Book due to tight spreads and commission structure.

Recommendations for Traders

To make the most of your trading environment at Exness:
  • Monitor execution quality regularly — including slippage, order speed, and rejections
  • Choose account types that match your strategy (e.g., Pro for A Book-style conditions)
  • Contact support if you need clarification about order behavior or have unusual execution issues
  • Be realistic about what matters — spreads, speed, and system uptime outweigh technical routing labels

Conclusion

So, is Exness A Book or B Book? The answer is — both, depending on the specific situation. Their hybrid model allows trades to be routed intelligently, balancing broker risk and client execution quality.
For most traders, the model used matters less than the outcomes: execution speed, platform stability, and order fill reliability. Focus on measurable performance, not the behind-the-scenes routing engine.
