A-Book, B-Book and Hybrid Risk Management for Brokers

    We design and operate the routing model behind your book: which flow you keep, which you pass to liquidity providers, and the rules that move clients between them.

    What's included

    Flow segmentation

    Group clients and accounts by trading behaviour, instrument mix and profitability, so routing decisions rest on data, not account type alone.

    Client profiling and toxicity scoring

    Identify consistently profitable, latency-sensitive or news-driven flow early, before it builds up on the B-book.

    Routing rules

    Define A-book, B-book and partial-hedge rules by group, symbol, size and client profile, configured in your bridge.

    Exposure limits

    Set net exposure limits per symbol and asset class, with clear triggers for hedging or re-routing.

    Ongoing review

    Regular reviews of B-book P&L, A-book costs and client reclassification as behaviour changes.

    Why it matters

    The routing model decides most of a broker's trading P&L. Keeping toxic flow on the B-book bleeds money, while sending the wrong flow to liquidity providers gives revenue away. A documented, data-driven model makes those decisions consistent and reviewable.

    Yes. Routing rules are configured in the bridge you already use, such as Centroid, PrimeXM or oneZero, within the agreed scope.
