When the application is launched, everything starts with JobModule. It configures the creation of Scheduler, which sends messages to SchedulerActor as given in the application.conf rate:

class JobModule extends AbstractModule with AkkaGuiceSupport {
    def configure(): Unit = {
        //configuring launch of price-fetching Actor
        bindActor[SchedulerActor]("scheduler-actor")
        bind(classOf[Scheduler]).asEagerSingleton()
    }
}

To enable this module, inside application.conf, the following line is required:

play.modules.enabled += "modules.jobs.JobModule"
