"""Nordnet Depository fetching for Nordnet, the scandinavian investment bank.
This fetcher uses the [Nordnet
API](https://www.nordnet.dk/externalapi/docs/api), which requires a Nordnet
account.
Some of the code here is based on [Morten Helmstedt's Nordnet
utilities](https://github.com/helmstedt/nordnet-utilities/blob/main/nordnet_login.py).
I am grateful for his pioneering work.
