UniverseOptions#

API documentation for tradeexecutor.strategy.universe_model.UniverseOptions Python class in Trading Strategy framework.

class UniverseOptions[source]#

Bases: object

Options that we can pass for the trading strategy universe creation.

Describe the dataset loading options, or override options for the internal testing purposes.

These can be given on the command line, or from the parent execution context. It allows to override parameters given in the strategy file easily without need to edit the file.

The most common use case is to speed up backtesting by decreasing the stop loss check frequency.

The default options do not override anything:

universe_options = UniverseOptions()

See Testing the strategy module how these options are used.

Both backtesting range and live trading history period can be given at the same time. In this case, the loaded data range is determined by ExecutionMode.
