SP500 data: loss and portfolio_value is nan

[lanqian110]

I have tried to use SP500 data to reproduce this code, and change some sql sequence. But, when i run the code,the loss and portfoilio_value is nan. My data and running result are shown below.


I wonder to know if the data needed to be preprocessed before run the code like normalization or anything else.

Looking forward to your reply!

Hi，
I saw your screenshots from 2023-11-28 showing NaN values in the loss and portfolio value with SP500 data. Did you manage to fix this issue?
