Retrieving crypto data

[Luis-ob-uc3m]

I was trying to retrieve some data from crypto market, for instance Bitcoin.

import pynance as pn
btc = pn.data.get('BTC-USD')
print(btc)

(I tried all the combinations, with capital letters, with - ....)

But the following result is returned, None:

If the source code of data.get is checked, we can see it uses the pandas_datareader

pynance/pynance/data/retrieve.py

Lines 18 to 38 in 3f7e8a7

	import pandas as pd
	import pandas_datareader.data as web
	import pynance as pn
	def get(equity, *args, **kwargs):
	"""get(equity, start=None, end=None)
	Get DataFrame for an individual equity from Yahoo!
	.. versionchanged:: 0.5.0
	Default `start` (2001-01-31) and `end` (current date).
	Examples
	--------
	>>> import pynance as pn
	>>> aapl = pn.data.get('aapl', '2014-03-01', '2015-03-01')
	>>> goog = pn.data.get('goog', '2014')
	"""
	df = web.DataReader(equity, 'stooq', *args, **kwargs)
	df.index = pd.to_datetime(df.index)
	return df

If we implement manually what the datareader does we can observe that it perfectly performs the data retrieve:

from pandas_datareader import data
btc = data.DataReader('BTC-USD','yahoo')
print(btc)

And the obtained result:

I do not know If I am wrongly coding something, but it seems like a bug or a feature it might be added

Having a look again to the code, we can observe a difference between the google documentation

and the implemented code, as it uses 'stooq' instead of 'yahoo'. I don't know if this can be the issue, but seems to be a clue.
