Purging 20 years of securities prices?
Seeking how to purge approximately 10 years of security prices (dozens and dozens of securities) dating back to 1998. Presently using Quicken Deluxe 2018 for Windows. I've been using Microsoft Money and now Quicken for a total of twenty years through multiple upgrades. Consequently, I've accumulated almost daily historical securities price updates for this entire 20 year period. I can only guess a database containing hundreds of thousands of daily prices risks a major data corruption issue. Is there any way to do a mass purge of this data (ie: a ten year range) rather than entering each security individually?? I've done this with transactions for years, but how can I dump all these historical securities prices?
