Topic hubs

    Trading Technology Topics, Clustered by Problem

    Each hub gathers the guides that explain one area end to end, plus the Gato modules that run it — so you can start from the problem rather than the product.

    How order management, execution management, FIX connectivity, and smart order routing fit together — with the Gato modules that run each layer.

    • — What an OMS does and how it differs from an EMS
    • — How smart order routing chooses venues and proves best execution
    • — FIX protocol basics, session management, and choosing a connectivity network

    About the hubs

    Start from the problem, not the product

    A trading stack is rarely replaced all at once. It is changed one obligation at a time: a reporting deadline, a market-access control that has to be provable, a settlement cycle that halved, a back-office process that stopped scaling with headcount. These hubs are organised the same way.

    Each hub collects the guides that explain one area completely — the terminology, the regulatory requirement, the architectural choices, and the failure modes that show up in production — and then links to the Gato modules that run it. Order and execution management covers OMS versus EMS, order state, smart order routing, and FIX connectivity. Regulatory reporting covers CAT and CAIS end to end, including customer and account linkage. Risk and margin covers pre-trade controls under SEC Rule 15c3-5 and intraday margin under FINRA Rule 4210. Post-trade operations covers T+1 settlement, clearing, corporate actions, reconciliation, and cash movement.

    What is a topic hub?

    A hub gathers every guide covering one area of trading infrastructure end to end — order and execution management, regulatory reporting, real-time risk and margin, or post-trade operations — alongside the Gato modules that run it.

    It lets you start from the operational problem rather than a product name.

    Which hub should I start with?

    Start with the obligation or bottleneck that is closest to hurting.

    Firms facing a reporting deadline start with regulatory reporting; firms scaling order flow start with order and execution management; firms with intraday margin or market-access exposure start with risk and margin; firms losing time to breaks and elections start with post-trade operations.

    Do the hubs map to specific products?

    Yes.

    Each hub links to the modules that address it — gHub and gTrader for execution, gPrecision and gReg for risk and reporting, gFlow, gPure, gView, gClarity, gNexus, and gPortal for operations — so a guide can be read straight through to an implementation path.

    How current is the regulatory content?

    Regulatory guides are revised when specifications, interpretations, or effective dates change, including CAT and CAIS technical specification updates and FINRA rule interpretations, rather than left at their original publication state.
