A trading simulator between a Broker and a Stock Exchange using the Financial Information eXchange (FIX) Protocol. It's a study project using QuickFIX/J, Quarkus, Angular, Docker, Docker Compose and PostgreSQL.

If you want to participate on this project, just open an issue and we can talk about!

Both Broker and Exchange systems were built with Quarkus on the back-end and Angular on the front-end.

The back-ends communicate each other with QuickFIX/J and each has a schema into the PostgreSQL.

Each Angular front-end communicates with the Quarkus back-end using REST and Websockets.

Inside the root folder of the project, execute:

$ chmod +x ./run-from-docker-hub.sh
$ ./run-from-docker-hub.sh

Docker Hub images:

• exchange-back-end
• exchange-front-end
• broker-back-end
• broker-front-end

Inside the root folder of the project, execute:

$ chmod +x ./run-with-local-build.sh
$ ./run-with-local-build.sh

After the first build, you can use the run-after-local-build script.

The default version of the development back-end projects is using H2 data base (in memory).

It's possible to change the application.properties and set them to run with PostgreSQL, in this case you should start a PostgreSQL container:

docker run -d --name postgres-qfj -p 5432:5432 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=postgres postgres
