Hi folks,

I am trying to multiply two time series shown below with the following command but the output is NaN.

Can someone help me?

Output:
Command>>print (portfolio.positions*portfolio.bars[['Adj Close']])

Output>>            AAPL  Adj Close
             Date                       
       1990-01-02   NaN        NaN
       1990-01-03   NaN        NaN
