Straight-Through Processing (STP) tools allow clients to create, negotiate and execute orders – all with seamless front to back office system integration.

The experience of creating direct connectivity with over 200 institutional investor clients' order management systems (OMS) allows MarketAxess to help integrate front and back office trading systems quickly and efficiently. According to our client investors' needs, MarketAxess connectivity solutions can be customized and configured independently or concurrently.

While STP connectivity can help investors to realize the full benefits of electronic trading, MarketAxess also offers API (application program interface) solutions to the dealer community. API connectivity to the trading system allows dealers to electronically submit inventory, negotiate trades, receive Notice of Executions (NOEs), acknowledge allocations and receive FINRA trade data.


In February 2013 MarketAxess completed its acquisition of Xtrakter Ltd., a leading provider of regulatory transaction reporting, financial market data and trade matching services to the European securities markets. In May 2014 Xtrakter rebranded to Trax, consolidating the firm’s suite of data and post-trade solutions under the reinvigorated Trax brand. Together, MarketAxess and Trax are uniquely placed to help their clients prepare for the broad-reaching changes taking place in the European fixed income markets due to incoming regulations. The combination of extensive market and reference data, a broad suite of protocols for trade execution and robust post- trade services mean that MarketAxess and Trax can offer dealers and investors a full suite of valuable tools to help manage their fixed income trading and investment risk.
