HORIZON

Educational crypto trading simulator, with no real money and no connection to any account. The app is a single HTML page with a simulated portfolio, prices from CoinGecko and Binance, and scenario analysis by Claude using the user's own key stored on their device. A separate Python script tracks public traders daily (Hyperliquid, OKX copy trading, SEC 13F filings) and logs their position changes as observed facts. Results are written to JSON, to a Markdown digest and, when configured, to Supabase for display in the app.
