historical_price single_day support

[jstockdi]

Summary (include Python version)

In:

iexfinance/iexfinance/stocks/historical.py

Line 19 in 64ee3af

self.start, self.end = _sanitize_dates(start, end)

self.end will never be None. Therefore, the single_day property will never be None

iexfinance/iexfinance/stocks/historical.py

Line 25 in 64ee3af

return True if self.end is None else False

Is this a bug or should the single day functionality be removed?

Date/time of issue

2021-01-10

Expected behavior

Not setting end_date will treat the request as a single day range

Actual behavior

Setting end_date defaults to today

Possible fix is to make an explicit argument, reflecting the API:
