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​

class ExecAlgorithm​

Bases: Actor

ExecAlgorithm(config: ExecAlgorithmConfig | None = None)

The base class for all execution algorithms.

This class allows traders to implement their own customized execution algorithms.

  • Parameters: config (ExecAlgorithmConfig , optional) – The execution algorithm configuration.
  • Raises: TypeError – If config is not of type ExecAlgorithmConfig.

WARNING​

This class should not be used directly, but through a concrete subclass.

add_synthetic(self, SyntheticInstrument synthetic) → void​

Add the created synthetic instrument to the cache.

  • Parameters: synthetic (SyntheticInstrument) – The synthetic instrument to add to the cache.

Logs an error if no VenueOrderId has been assigned to the order.

  • Parameters:
    • order (Order) – The order to cancel.
    • client_id (ClientId , optional) – The specific client ID for the command. If None then will be inferred from the venue in the instrument ID.

cancel_task(self, task_id: TaskId) → void​

Cancel the task with the given task_id (if queued or active).

If the task is not found then a warning is logged.

  • Parameters: task_id (TaskId) – The task identifier.

clock​

The actors clock.

  • Returns: Clock

config​

The actors configuration.

  • Returns: NautilusConfig

degrade(self) → void​

Degrade the component.

While executing on_degrade() any exception will be logged and reraised, then the component will remain in a DEGRADING state.

WARNING​

Do not override.

If the component is not in a valid state from which to execute this method, then the component state will not change, and an error will be logged.

deregister_warning_event(self, type event) → void​

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.
