Hi Everyone,
I am using the research environment to make a dataframe and have run into a slight issue. Specifically, I have used the folling code to try and add fundamental data values, but I am confused why the corresponding fundamnetal data values are not being inputted. Does anyone have an explanation for this issue? Thanks.

Go to the file that says TEST.ipynb. The issue is within the 8th cell. Thanks.

Hi Ari,
The reason they are NaN is because we are trying to stuff pandas DataFrame objects into a cell. To address this, we need to index the DataFrame to get a singular value. Furthermore, we want to increase the days for fundamental data to reduce the chances of getting an empty DataFrame, and if we do, we need to make sure we don't try to index it. I've shown this in the attached backtest.
Best,
