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.

- run_in_executor ( self, func: Callable[..., Any], tuple args=None, dict kwargs=None ) ¶
-
Schedules the callable func to be executed as fn(*args, **kwargs) .
- Parameters :
-
-
func ( Callable ) – The function to be executed.

For backtesting the func is immediately executed, as there’s no need for a Future object that can be awaited. In a backtesting scenario, the execution is not in real time, and so the results of func are ‘immediately’ available after it’s called.
