Overview

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.

Running the project

With docker-compose

After start, access project at:

• Broker Front end
  • http://localhost/
• Broker Back end swagger:
  • http://localhost:8080/q/swagger-ui/
• Exchange Front end
  • http://localhost:90/
• Exchange Back end swagger:
  • http://localhost:8090/q/swagger-ui/
• PostgreSQL:
  • jdbc:postgresql://localhost:5432/postgres
  • user: postgres
  • password: postgres

The containers should be running like this:

docker ps

Using the Docker Hub Images

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

Building the Docker images locally

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.

Without docker-compose

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

Enter inside the exchange-back-end folder and type:

$ ./mvnw compile quarkus:dev -Ddebug=5006

Access http://localhost:8090/q/swagger-ui/

Enter inside the broker-back-end folder and type:

$ ./mvnw compile quarkus:dev

Access http://localhost:8080/q/swagger-ui/

Enter inside the exchange-front-end folder and type:

$ npm install
$ ng serve

Access http://localhost:4300

Enter inside the exchange-back-end folder and type:
