Challenge
The Exchange used native APIs for order flow and market data services. The Exchange wanted to build a FIX-compliant client interface to enable banks, brokers, and investment companies to conduct trades on the exchange using the FIX Protocol.
Solution
The FIX Gateway is a FIX-compliant client gateway performing the translation and routing of FIX messages from clients to appropriate calls to the Exchange's REST or Websockets APIs, as well as the translation and routing of replies from the Exchange's REST and Websockets APIs to the appropriate FIX messages.
- FIX Gateway supports Market Data and Trading message flows combining the use of REST and Websockets APIs
- FIX Gateway is able to process hundreds of messages per second in each FIX session
- Mapping between FIX messages and JSON API messages and vice versa is scripted
- Supported protocols: FIX 4.4
