Hi
I see syntax for fetcher like this: (note the usecols)
fetch_csv(yahoo_vix_url, date_column='Date', date_format='%Y-%m-%d', symbol='vix', usecols=['Adj Close'], post_func=post_func)
context.xiv = sid(40516) #xiv
I don't see the API mentioning something like the usecols. Is that my lack of experience in python or I missed some other API doc ?
