Trading intelligence for traders who don't have time to read the news. Built solo over a gap year. Already in the wild.
Catalyst pulls real market data from a curated mesh of providers, then scores everything through a three-tier intelligence pipeline. Each surface gets its own rhythm, its own intel.
Real-time price action, support and resistance auto-detection, dominance overlay, CME gap notices and holiday flags. Built for traders who run BTC as a primary book.
Eight major and cross pairs ingested via Frankfurter. Scoring model rebuilt from the ground up with realistic move thresholds — not hyped pip swings dressed up as signals.
Rebuilt from the NASDAQ shell using SPY as proxy through Alpha Vantage's free tier. Same architecture, asset-tuned colour, asset-tuned signal weighting.
gold-api.com powers metals pricing after evaluating three providers. Real yield context, dollar-index overlay, physical-versus-futures basis flags.
Catalyst was engineered solo using modern tooling. A React frontend deployed via Netlify, a curated API mesh across four asset classes, and a three-tier intelligence pipeline holding it all together.
Catalyst's code values clarity over cleverness. Hooks are flat, names are descriptive, every score traceable back to its tier.
