      Does anyone know why

      bt.feeds.YahooFinanceData(dataname='VTI', period='w', fromdate=datetime.datetime(2018,1,1), todate=datetime.datetime(2020,1,1))
      

      does not work? It return daily data instead.

        Try this instead of period...

        timeframe=bt.TimeFrame.Weeks,

          timeframe=bt.TimeFrame.Weeks

          Works perfectly. This syntax is quite different from what indicated in the docs though.

            I could be wrong and maybe someone with more tenure can chime in, but I think yahoo stopped working for a while and the docs might be a bit out date. I dug this out of the code.
