Does anybody know how the CSV file should look like to import Sec price over 5years?

Hi

Quicken only allows the download of historical prices for the past five years. However, I have stocks purchased in 2014 and 2016, and I would like to obtain historical prices for these stocks covering the period from 2015 to 2020.

I noticed that Quicken provides an option under File > File Import > Import Security Prices from CSV File. However, I am unable to locate any documentation or specific guidelines on the required file or field structure for this import process.

Any additional insight would be appreciated.
