Introduction

We are creating a stock market simulation, where the user can invest in-game currency in a simulated market completely separated from the real world. By providing custom events that pop up randomly and alter the course of our stocks, coupled with a market that never sleeps, we are presenting a fun and fast-paced introduction into the stock market. This is the repository for the backend, the corresponding frontend can be found here.

Running the app:

After installing all the requirements, start the program by running $ go run main.go.
The console should output information about the status of the program:

INF successfully connected to the database
INF successfully started the game loop
INF successfully started the http server address=localhost:5000

It will then load the last tick from the Database before printing it and the ingame time:

DBG running tick date="2020-01-01 00:00:00 +0000 UTC" tick=2

After this setup, the program prints the indices from the two currently implemented stocks Google and Apple. This is done every 10 seconds, like this:

DBG updated stock index=60032 name=GOOG
DBG updated stock index=60024 name=APPL
