Merriman Market Timing iOS
A niche trading tool that pays for itself
iOS app detecting market reversal scores via weighted historical values for DJIA, Nasdaq, Gold, and Silver. Built on 50+ years of data.
> the problem
I got into financial market timing through a weekend seminar in Detroit. I flew out on a whim to study with Ray Merriman, widely considered the godfather of financial astrology. His market timing research is the best in the world, backed by 50+ years of historical data. I loved the community, saw that the field had no modern tools to put this research in traders' hands, and built one.
> the approach
Same process I used for Affirm Me. Designed the full UX in Figma, workshopped the concept, then built it in SwiftUI with a Supabase/PostgreSQL backend. The app delivers solar-lunar reversal scores, historical correlation data, and short-term trading signals based on 50+ years of daily price movements across DJIA, Nasdaq, Gold, and Silver.
> the lessons
The app is live and paying, and it earned the client's trust well enough that they brought me back to rebuild their entire 7-figure subscription platform. Technically, the interesting work was in the signal modeling and the PostgreSQL design underneath it; I also found the performance limits of Supabase's data access layer the hard way, which is its own kind of useful.
