Inspiration
- Bloomberg โ rank-percent filtering, multi-asset terminal aesthetic
- Finviz / MarketInOut โ fundamental + technical screener layout
- TradingView โ interactive Lightweight Charts
- Stockopedia โ composite Quality/Value/Momentum/Growth/Stock ranks
- WhaleWisdom / Whale Watcher โ Form 4 insider transactions
- AlphaSpread โ DCF calculator with editable assumptions
- Schwager โ Market Wizards โ risk-adjusted-return discipline, position sizing
Free-data limits we accept
- No real-time tick data โ daily bars only
- No paid news / sell-side research
- Survivorship bias in the universe (current Russell 3000 only)
- Fundamentals are point-in-time-now snapshots, not point-in-time-correct historical (EDGAR XBRL is on the roadmap)
- yfinance occasionally rate-limits โ some symbols may be missing on any given day
Not investment advice. For research only. Past performance does not guarantee future results.
Roadmap
- Now: dashboard, screener, charts, ranks, insiders, DCF, macro stub
- Soon: 13F whale-tracking page (Burry, Buffett, etc.), news feed, options chains, alert builder
- Later: international universe (~10k via FinanceDatabase + Stooq), point-in-time fundamentals via EDGAR XBRL, prediction-market integration (Polymarket / Kalshi), live paper trading
