      Hello,

      I am having an issue with this line of code

      monthly_std_dev = bt.indicators.StandardDeviation(data.close, period=63)
      yk = ema_difference / monthly_std_dev
      

      The error I get is array index out of range for the monthly_std_dev variable. The ema_difference list the difference between EMA 96 and EMA 32.

      Can someone help?
