I used this example but unfortunately got errors. The full traceback is:

Having the same issue. It seems the yahoo API has changed again. Backtrader cannot find "CrumbStore" in the reply (yahoo.py:278):

i = txt.find('CrumbStore')

[martzz]

Apparently, the crumb cookie is no longer needed by the yahoo API. So the first phase of obtaining the cookie can be discarded and the whole fetching simplified in yahoo.py.

Works for me just delete all the crumb related code in yahoo.py. Deleting code is always satisfying.
