Hi @kal8na
So the question is asking for more than just joining the two tables.
– It’s looking for the last date
– It’s looking you to add two extra columns bid and ask which contain information from the nbbo table
Here is an example from the documentation to help (screenshot below).
If you have any further questions please let me know!
Thanks,
Megan
