Build options intuition in a private, offline lab. Options Analysis Suite is a Black-Scholes pricing engine, strategy explorer, portfolio Greeks aggregator, and interactive learn library - no broker, no login, no live feed. ANALYZE, TEST, LEARN • Black-Scholes Calculator - Compute option price, core Greeks, and advanced Greeks from your own spot, strike, IV, rate, dividend, and expiry assumptions. Greeks update live as you adjust parameters. Sensitivity charts show how each Greek changes across spot. • Strategy Explorer - 17 classic option strategies (Long Call, Iron Condor, Bull Call Spread, Calendar Spread, Straddle, Strangle, and more) with payoff-at-expiry diagrams, T+0 overlays, max profit / max loss / breakeven summaries, and probability-of-profit calculations under a lognormal model. Compare two strategies side by side. • Portfolio Sandbox - Aggregate Greeks across multiple hypothetical positions and symbols so you can see portfolio-level exposure, not just one trade at a time. View Δ, Γ, Θ, V, ρ totals plus second-order Greeks (vanna, charm, vomma, veta) and optional third-order. Load from strategy templates or build positions from scratch. • Trade Journal - Record hypothetical trade entries, mark them closed at any user-supplied close spot and IV, and reflect with Greeks-at-entry vs Greeks-at-close side by side. Tag closed trades with the lessons they taught you, then jump back to the matching learn module to review the concept. • Learn Modules - Interactive lessons covering Greeks Surface, IV Smile & Skew, Probability Cone, Per-Expiration IV term structure, Pin Risk, Earnings IV crush, Dealer Hedging Mechanics (GEX / gamma flip / pinning), Stress Tests, plus new Beginner Foundations: What are Options?, Reading the Option Chain, Bid-Ask Spread Math, Assignment & Exercise, Put-Call Parity, and POP vs Expected Value, and more. Every module has live sliders so you can manipulate the underlying mechanics yourself. • Daily Practice - Rotating quiz format covering beginner, intermediate, and advanced options concepts. WHO IT'S FOR Self-directed options learners. People who use a broker for actual trading and want a separate, focused space to build understanding away from a live order ticket. Anyone working through an options textbook, preparing for derivatives coursework, or studying for professional finance exams who needs a sandbox to test concepts. OFFLINE BY DESIGN No brokerage. No live market data. No trades. No account. No ads. No tracking. Nothing leaves your device - calculator inputs, strategy setups, portfolio positions, and trade journal entries are stored only in local storage on your phone, and the app works entirely offline. All P&L figures, risk numbers, and trade-journal entries are hypothetical Black-Scholes projections under your own supplied parameters. They are educational examples, not investment advice. Real options trading involves substantial risk, including the risk of losing more than your initial deposit. Always do your own research and consult a licensed financial advisor before trading.
