A hands-on tool for understanding how options are priced, how strategies behave under different market conditions, and what the Greeks actually mean. Built for learning.
See how Delta, Gamma, Theta, Vega, and Rho shift across the full price range (not just at one strike).
Plot the payoff curve of any single-leg or multi-leg position and understand exactly where it profits or loses.
Read the IV on any contract, compare it to historical vol, and see how the market is pricing uncertainty.
Watch how Theta erodes extrinsic value day by day, and learn why it accelerates as expiration approaches.
Build spreads, straddles, condors, and butterflies legs to see how combining options changes risk.
Change spot price, volatility, or days to expiry and see how your position responds in real time.
Every concept is shown with live numbers. Adjust a parameter and see the effect immediately, without memorizing equations first.
No subscription, no account wall, and no ads. Recent market data is fetched so you can open the tool and start learning.
Option chains are pulled live for any US equity or ETF. You learn with similar prices you'd see on a brokerage platform.
Heatmaps show profit and loss across every price level, so you understand the full risk profile (not just the breakeven).
Filter by IV rank, skew, and liquidity across hundreds of tickers to compare how options are priced across the market.
Save multiple setups and compare them side by side. Useful for studying how the same strategy behaves across different underlyings or expiries.
