Need help with google sheet formula

I need help with google sheet and will appreciate any suggestions.

I have a stock portfolio in google sheets with total value displayed on the bottom.

I am trying to make a table with just two columns, 1) Date 2) total value for that date, and everyday it will store a new total value for that date..

I am trying to write a formula in the table to store total value based on the date.

Please help.  

Thanks,
