A while back I wrote some stock market algorithms and charting software I use in my own DYOR daily stock analysis. I decided to offer up that daily information to others. I changed my SaaS delivery approach idea to be a daily Substack newsletter instead. It is a stock market info newsletter called StockQuakes ( https://stockquakes.substack.com ) . With Substack my newsletter grew by using the Substack Recommendations feature as well as their Notesfeature. Substack takes care of the signups, etc. via Stripe. You have to have value above and below the paywall line in the newsletter to keep users. And you have to have a free version in addition to the paid version. I also put up a separate website to drive SEO traffic to the newsletter ( https://stockquakes.com ). And I post on BlueSky, Threads, and X/Twitter daily in addition to Substack Notes. Have 600 users, 5000 followers.
