Hi Everyone!

I have a dataset of daily closing price of stocks for 2020. Since I am interested in calculation of returns over specific periods (Covid-19 Market crash). For example, I want to calculate the returns between 20 Jan 2020 and 3 Jan 2020.

I have tried different approaches but got no result. I just want to know how I can perform this operation while adding the dates condition and results will be shown in the same row.


Best regards,
Peter Klein
