Common ¶
The common subpackage provides generic/common parts for assembling the frameworks various components.
More domain specific concepts are introduced above the core base layer. The ID cache is implemented, a base Clock with Test and Live implementations which can control many Timer instances.
Trading domain specific components for generating Order and Identifier objects, common logging components, a high performance Queue and UUID4 factory.
The Actor class allows traders to implement their own customized components.
A user can inherit from Actor and optionally override any of the “on” named event methods. The class is not entirely initialized in a stand-alone way, the intended usage is to pass actors to a Trader so that they can be fully “wired” into the platform. Exceptions will be raised if an Actor attempts to operate without a managing Trader instance.

Executor ¶
- class TaskId ( value : str ) ¶
-
Bases:
object
Represents a unique identifier for a task managed by the ActorExecutor.
This ID can be associated with a task that is either queued for execution or actively executing as an asyncio.Future .
- class ActorExecutor ( loop : AbstractEventLoop , executor : Executor , logger : LoggerAdapter ) ¶
-
Bases:
object
Provides an executor for Actor and Strategy classes.
Provides an executor designed to handle asynchronous tasks for Actor and Strategy classes. This custom executor queues and executes tasks within a given event loop and is tailored for single-threaded applications.
The ActorExecutor maintains its internal state to manage both queued and active tasks, providing facilities for scheduling, cancellation, and monitoring. It can be used to create more controlled execution flows within complex asynchronous systems.
- Parameters :
-
-
loop ( AbstractEventLoop ) – The event loop for the application.
-
executor ( Executor ) – The inner executor to register.
-
logger ( LoggerAdatper ) – The logger for the executor.
-
Warning
This executor is not thread-safe and must be invoked from the same thread in which it was created. Special care should be taken to ensure thread consistency when integrating with multi-threaded applications.
- reset ( ) None ¶
-
Reset the executor.
This will cancel all queued and active tasks, and drain the internal queue without executing those tasks.
- get_future ( task_id : TaskId ) _asyncio.Future | None ¶
-
Return the executing Future with the given task_id (if found).
- Parameters :
-
task_id ( TaskId ) – The task identifier for the future.
- Returns :
-
asyncio.Future or
None
- async shutdown ( ) None ¶
-
Shutdown the executor in an async context.
This will cancel the inner worker task.
- queue_for_executor ( func : Callable [ [ ... ] , Any ] , * args : Any , ** kwargs : Any ) TaskId ¶

- Parameters :
-

Return a value indicating whether there are any active tasks.
- Returns :
-
bool
- cancel_task ( task_id : TaskId ) None ¶
-
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 active task identifier.
- cancel_all_tasks ( ) None ¶
-
Cancel all active and queued tasks.
