backtest_lib.universe.universe_mapping.UniverseMapping#

class backtest_lib.universe.universe_mapping.UniverseMapping#

Bases: VectorMapping[str, Scalar], ABC, Generic

Vector mapping keyed by security identifiers.

Implementations back this interface with dense vectors aligned to a universe ordering, enabling fast arithmetic when operands share the same ordering.

abstractmethod floor() → UniverseMapping[int]#

Return a mapping with values floored to integers.

property plot: UniverseMappingPlotAccessor#

Return the plotting accessor for the mapping.

abstractmethod truncate() → UniverseMapping[int]#

Return a mapping with values truncated to integers.
