That "predictor" or monetary stock and flow theory that blog post describes is well over 100 years old now and very well known (pre-Keynesian and going back to at least Irving Fisher). It has also been studied in detail in academia for decades if anyone wants to look up proper research studies about it. The blog author maybe should have mentioned that this is already a well known and tested predictor, and if the author hadn't heard of before writing that blog post I would question that entire site. There are also several companies that specialize in providing this exact cash/equity data research to financial firms to help them manage their trading strategies and offering more practical details in their data than FRED data offers. For example TrimTabs [1] (no affiliation) has been around since 1990 according to their website [1] trimtabs.com
