Options education · Free
Every options trade tells a story.
This tool lets you read it.
See the breakdown of your option P&L into Δ / Γ / Θ / Vega contributions in dollars. Simulate any scenario. Ask an AI trained on your live position — all before you risk capital.
What you get
Four features most free options tools skip.
P&L Decomposition
Break any scenario's P&L into Δ / Γ / Θ / Vega dollar contributions — with the formula visible. The differentiator.
Time Machine
Sliders for days, spot shock, IV shock — plus preset scenarios that isolate one Greek at a time, and a custom-scenario input for exact values.
AI Assistant
Claude reads your live position and calls the actual simulator to answer 'what if' questions. Real numbers, not hallucinations.
Live Market Data
Type any US ticker — spot, real expiry dates, and ATM implied volatility autofill from yfinance.
How it works
Build a position
Pick a preset (long call, iron condor, straddle…) or add custom legs. Fetch a live US ticker to autofill spot, expiries, and ATM IV.
Read your Greeks in dollars
Δ / Γ / Θ / Vega / Rho aggregated across all your legs. Every value comes with a plain-English interpretation.
Simulate before you trade
Move time forward. Shock the underlying. Jolt IV. See your P&L broken down by Greek — with the exact formula that produced each number.
Who it's for
Retail options traders, 6-24 months in — you know what a call is, you've done a wheel or two, but the Greeks still feel like homework. You want to stop “trading by vibes” and start understanding whyyour trades work or don't.
Not for institutional traders (you have Bloomberg). Not for pure beginners (start with a basic options course first).
