If you are working in trading based company then it’s very important to have knowledge of FIX (Financial Information eXchange) protocol.
What is FIX: It’s electronic communications protocol which was initiated in 1992 for international real time exchange of financial information related to markets and securities transactions.

Financial institutions entities are investing too much of money optimizing electronic trading application and employing direct market access (DMA) in hope of increase to submit orders to speedily to the financial markets. It’s very important to manages delivery of trading orders and keeping low latency increasingly requires very strong understanding of FIX protocol.
I understand, you wanted to see actual implementation of it without reading more details about it but if you are still very curious to know more about it just google it you will see many details of FIX protocol. Finding details of FIX protocol through Google is very easy but actual implementation is rare where you could see end to end working application. Before writing this application I searched lot never find any good tutorial example which would give basics of FIX protocol and simple to understand. That’s why I am writing this tutorial to get how FIX protocol works. Let’s jump on it:
Basically to develop end to end and perform test you need two application:
- FIX Acceptor (Called as FIX Server) – Server process the FIX message its nothing but exchange you sent your order for processing
- FIX Initiator (Called as FIX Client) – Client are broker who send order to the exachange in FIX format.
Note: To develop this application we will use QuickFIX/J which is 100% java open source FIX engine and very famous in the industry. All jars available through maven repository except below jars:
- Create maven project FIXProtocolAcceptor below is details project structure:
Note: Remaining files you download from the bottom link
- Now let’s create FIX client for this you will have to create separate project name: FIXProtocolInitiator below is complete project structure:
- To keep this tutorial short you could copy others file shows in project from download link below. Not its time to run this application. First start FIXProtocolAcceptor which is exchange server in our case and it’s java application so you could run inside eclipse as java application, if everything set up correctly you will see below output on the console:
- As you see sever is started and its ready to accept the order now let’s start our client and send some order to the server. To start client right click FixInitator.java class as java application you will see below output as it’s showing order send successfully to the exchange:
- Server output:
- That’s it.
