  • Technology

    Tradeweb's technology is based on a client/server architecture that uses industry-standard protocols and tools. The client side of the electronic trading application is implemented using the Tradeweb Viewer, a small, intelligent program which runs on an individual workstation or on a network file server at the client site.

    The Tradeweb Viewer runs on the most popular platforms used by the financial community - the Microsoft Windows range of operating systems - and communicates across the network over a real-time, encrypted TCP/IP point-to-point socket connection to Tradeweb's data processing center.

    The Tradeweb Viewer displays real-time, best bid and offer prices from the largest dealers for a range of products, and offers interactive and simultaneous trading with multiple dealers.


    The viewer initiates an outbound TCP/IP connection to Tradeweb Servers using specific TCP ports. Clients must register their IP addresses with Tradeweb's firewall and user database.

    Tradeweb has carefully selected its Internet Service Providers (ISPs) to provide the most reliable service available today to its clients. Using only 'tier 1' Internet backbone ISPs in a 'multi-homed' architecture, Tradeweb provides fully resilient connectivity on all published addresses.


    The session between the Tradeweb Viewer and the Tradeweb Server is encrypted using RSA security - considered the gold standard for cryptography.

    Each Tradeweb user is assigned a unique user name and password. The user name, password, and client's IP address must all match to be authenticated by Tradeweb when a connection is attempted.

    Once authenticated, the Viewer establishes a session with a Tradeweb Server; the Viewer can only connect to Tradeweb application servers.

    Trade Processing

    Trade processing is supported by functionality provided via the Viewer, and by Application Protocol Interfaces (APIs). The APIs use either FIX or XML to allow a client to connect a computer to Tradeweb servers and implement trade processing using messages exchanged between Tradeweb and client machines.
