root_accessors module

Root pandas accessors.

An accessor adds additional “namespace” to pandas objects.

The vectorbt.root_accessors registers a custom vbt accessor on top of each pd.Series and pd.DataFrame object. It is the main entry point for all other accessors:

vbt.base.accessors.BaseSR/DFAccessor           -> pd.Series/DataFrame.vbt.*
vbt.generic.accessors.GenericSR/DFAccessor     -> pd.Series/DataFrame.vbt.*
vbt.signals.accessors.SignalsSR/DFAccessor     -> pd.Series/DataFrame.vbt.signals.*
vbt.returns.accessors.ReturnsSR/DFAccessor     -> pd.Series/DataFrame.vbt.returns.*
vbt.ohlcv.accessors.OHLCVDFAccessor            -> pd.DataFrame.vbt.ohlc.* and pd.DataFrame.vbt.ohlcv.*
vbt.px_accessors.PXAccessor                    -> pd.DataFrame.vbt.px.*

Additionally, some accessors subclass other accessors building the following inheritance hiearchy:

vbt.base.accessors.BaseSR/DFAccessor
    -> vbt.generic.accessors.GenericSR/DFAccessor
        -> vbt.cat_accessors.CatSR/DFAccessor
        -> vbt.signals.accessors.SignalsSR/DFAccessor
        -> vbt.returns.accessors.ReturnsSR/DFAccessor
        -> vbt.ohlcv_accessors.OHLCVDFAccessor
    -> vbt.px_accessors.PXSR/DFAccessor

So, for example, the method pd.Series.vbt.to_2d_array is also available as pd.Series.vbt.returns.to_2d_array.

Note

Accessors in vectorbt are not cached, so querying df.vbt twice will also call Vbt_DFAccessor twice.

register_accessor function

register_accessor(
    name,
    cls
)

Register a custom accessor.

cls should subclass pandas.core.accessor.DirNamesMixin.

register_dataframe_accessor function

register_dataframe_accessor(
    name
)

Decorator to register a custom pd.DataFrame accessor on top of the pd.DataFrame.

register_dataframe_vbt_accessor function

register_dataframe_vbt_accessor(
    name,
    parent=vectorbt.root_accessors.Vbt_DFAccessor
)

Decorator to register a pd.DataFrame accessor on top of a parent accessor.

register_series_accessor function

register_series_accessor(
    name
)

Decorator to register a custom pd.Series accessor on top of the pd.Series.

register_series_vbt_accessor function

register_series_vbt_accessor(
    name,
    parent=vectorbt.root_accessors.Vbt_SRAccessor
)

Decorator to register a pd.Series accessor on top of a parent accessor.

Accessor class

Accessor(
    name,
    accessor
)

Custom property-like object.

Note

In contrast to other pandas accessors, this accessor is not cached!

This prevents from using old data if the object has been changed in-place.
