I don;t think so based on the traceback...

Did you check what parameters were required for this function?
The error says you are missing one.

Some warnings there that might be relevant, I don't know
anything about the package or function.

You could try running the help() function:

>>> help(quotes_historical_yahoo_ochl)

And see if it shows anything useful.
