Execution
The execution subpackage groups components relating to the execution stack for the platform.
The layered architecture of the execution stack somewhat mirrors the data stack with a central engine, cache layer beneath, database layer beneath, with alternative implementations able to be written on top.
Due to the high-performance, the core components are reusable between both backtest and live implementations - helping to ensure consistent logic for trading operations.
Components

This class allows traders to implement their own customized execution algorithms.
- Parameters: config (ExecAlgorithmConfig , optional) – The execution algorithm configuration.

The ExecutionEngine is the central component of the entire execution stack.
The execution engines primary responsibility is to orchestrate interactions between the ExecutionClient instances, and the rest of the platform. This includes sending commands to, and receiving events from, the trading venue endpoints via its registered execution clients.
The engine employs a simple fan-in fan-out messaging pattern to execute TradingCommand messages, and process AccountState or OrderEvent type messages.
Alternative implementations can be written on top of the generic engine - which just need to override the execute and process methods.
