Interface Accounting

public interface Accounting

Common interface for the PowerTAC accounting service. The accouting service module is responsible for bookeeping, with respect to cash (broker bank accounts) and market positions on behalf of brokers. All activities that could potentially affect cash or market positions must be recorded by making calls on the Accounting API. Summaries of accounts, along with all new transactions, are sent to brokers at the end of each timeslot.

Accounting is also a TimeslotPhaseProcessor, running in the last phase of the simulation cycle. All processors that can generate transactions must run in earlier phases.
