BaseDataProvider¶

class BaseDataProvider[source]¶

Bases: abc.ABC

The abstract base class for data_provider modules within Qiskit’s finance module.

To create add-on data_provider module subclass the BaseDataProvider class in this module. Doing so requires that the required driver interface is implemented.

To use the subclasses, please see https://github.com/Qiskit/qiskit-tutorials/blob/master/tutorials/finance/11_time_series.ipynb
