Problem: Traders and learners need a way to practice entries, exits, and sizing against live market data without sending a real order. Solution: Built a React Native / Expo paper desk that reads a live Nasdaq and CoinGecko tape, scores liquid US names and top coins, and lets an automated dealer rebalance a $5,000 simulated book. Each hour it drafts a trade idea—stocks, crypto, or options—with in/out prices and strategy copy; Take a spoof puts it on Mine with no order sent. Sim and Mine fills sync to Firebase Firestore, with an optional OpenAI desk server for the playbook. Outcome: A mobile paper-trading app with Tape, Book, Sim, Mine, and Scan—explicitly paper only, EAS-ready for iOS and Android.
