qiskit.finance.data_providers.BaseDataProvider

class BaseDataProvider

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/legacy_tutorials/aqua/finance/data_providers/time_series.ipynb

abstract __init__()
