  • Gamma Three Trading's FIXHub in Production

    Gamma Three Trading's FIXHub goes live at a large Asset Manager in Boston, MA with over $200 Billion Assets Under Management. FIXHub provides seamless integration of Order Management Systems by connecting each OMS via the FIX Protocol, allowing orders, executions, allocations, etc. to flow between them.

    A common reality on trading desks is that different OMS platforms work better for different asset classes, and traders prefer one platform over another. Some desks focus on equities, others on foreign currency and bonds, while another uses a different system to manage OTC derivatives. By using FIXHub, trades and trade details can be passed between these systems, allowing execution to occur on any platform.

    This ability greatly reduces the costs and aggravation of platform consolidation and lost features by choosing a common denominator. By using FIXHub, the initial client has combined desks using different OMSs (and even 2 instances of the same OMS) into one unified platform using FIXHub.
