      Hello,
      I'm new in the community so I hope this is the right place for this question:
      I've downloaded a few minutes bars of BTC/USD and I was testing the Sharpe Ratio with the SMA_CrossOver strategy included with BT but it keeps giving me:
      Sharpe Ratio: OrderedDict([('sharperatio', None)])

      The dataframe i'm feeding Cerebro has columns :
      ['Open', 'High', 'Low', 'Close', 'Volume', 'Datetime']
      the index also is called Datetime (is set equal to the last column)
      I'm on Windows but I'm using Notepad++ and launching scripts with a macro within Notepad++

      I've uploaded both my (simple) script and the data over Drive
      I'm worried it may be something basic or really stupid of my code but i can't find it.
      If someone can help me I'd really appreciate it.
      Thanks, Andrea.

        The most obvious thing: how you load the dataframe yields 0 data points and no operations is executed.

        Easy to see by simply checking the length of the data at stop and it will probably be 0

          Ok, not that simple: I've add
          self.log('Data size: '+str(self.data.line.lencount), doprint = True)
          both in stop and in next and it shows the data is growing up to 300 bars.
          I'm also plotting the strategy and it is opening positions:
          0_1535902353195_It does something.png
          By the way I forgot saying i'm using the default
          bt.feeds.PandasData(dataname = df, timeframe=bt.TimeFrame.Minutes)
          to load the bars.

          Here is the slightly modded SMA_CrossOver strategy i'm using:

            @kyouma-hououin said in Problems with Analyzer and Pandas Datafeed:

            bt.feeds.PandasData(dataname = df, timeframe=bt.TimeFrame.Minutes)

            The SharpeRatio defaults to analyzing yearly returns (which is what the industry does) and cannot find any with your Minutes input. See: Docs - Analyzers Reference

            You can configure it to use timeframe=bt.TimeFrame.Minutes, but imho ... that's not something you would really want to do.
