Candlesticks generation application

Dependencies

Application uses Redis as a storage of candlesticks.

How to use

1. Build an image (two options)
   • /gradlew bootBuildImage — Gradle task bootBuildImage builds an image builds much faster (recommended).
   • docker-compose build app — there is a Dockerfile
2. Set proper value to TICKS_SOURCE_URL environment variable in docker-compose.yml. I left it empty in the repository in order to hide it from the society. =)
3. Run docker-compose — docker-compose up
4. Start receiving ticks with curl -v http://127.0.0.1:8080/start
5. Wait for it...
6. Request candles with curl -v http://127.0.0.1:8080/candles?stock=AAPL&from=1652331300&to=1662331300
7. Enjoy ^_^
8. You can stop receiving ticks with curl -v http://127.0.0.1:8080/stop

Note

There is an intermediate solution in the repository in files:

• class CandlesServiceRealtimeImpl.
• class TicksProcessorRealtime

It was my first solution. In this case application builds candles in realtime for every request. Works pretty fast. You can check it by switching @Primary annotations to these classes.
