Solo dev, been building this for months. The idea: take Wyckoff methodology (a 100-year-old framework for detecting institutional buying) and quantify it with actual backtested accuracy numbers.
Most stock analysis tools give you indicators with no proof they work. I wanted to know: does this actually predict anything?
So I backtested across 242 stocks from 2006-2025. Results: 58% daily win rate, 63% weekly, and when both timeframes agree, 65% at a 40-day hold with +1.95% alpha over the S&P 500.
Built the whole thing solo React/TypeScript frontend, Supabase backend, scanner runs every weeknight across 223 US stocks. Launched this week with a free trial.
Two signups so far. Reddit has been brutal with spam filters on a new account. Twitter thread got some eyes but nothing crazy.
Honestly not sure what the right marketing move is from here. Would love to hear from anyone who’s launched a niche financial tool , what worked for you?
