I have a spreadsheet that has a DDE link that updates data in a spreadsheet.

Row 1 has stock symbols
Row 2 has price data (that updates every minute)

(this is not the real data - i am just simplifying)

Every 5 minutes, in a separate sheet, I would like, to have this data to be
updated in a list of descending order.

I can make a macro to do this, but I would like to automate this macro (or
code or whatever) to run every 5 minutes. Is that possible?
