Options Payoff Calculator (SentiSense)
Most payoff calculators start empty and ask you to type in a price, a strike and a volatility. This one starts full. It fetches one ticker's last price, its at-the-money implied volatility at roughly 30, 60 and 90 days, its 25-delta skew, its IV rank and its next earnings date from the read-only SentiSense API, binds them into a reviewed HTML template that ships with the skill, and hands back a single self-contained file: a profit-and-loss-at-expiry diagram for nine common strategies, with breakevens, max profit, max loss, and the expected move band drawn in behind the curve so the payoff is read against what the market is actually pricing.
The artifact renders offline. Everything it needs is inlined at build time, so it opens with no network access, no external stylesheet and no script from anywhere else. The strategy picker, the strike and expiry controls and the diagram all work from the bound snapshot. It is a file you can keep, screenshot, attach to a note, or open next week and still have render.
Read-only educational data interface. Every premium it prints is modeled from end-of-day implied volatility, not quoted from an options chain, and the output is informational context, never a personalized buy or sell recommendation. Nothing here places an order.
When to Use
- "What does a $220 call on $NVDA look like?", "draw me the payoff for a covered call"
- "Where does this spread break even?", "what is the max loss on an iron condor here?"
- "Is a straddle or a strangle better into this report?" (the diagram shows both against the same expected move band)
- "What would selling a cash secured put 5% below here pay me?"
- Any time the shape of a position communicates better than four numbers in a sentence.
Not this skill: options flow and positioning readings such as put/call percentiles, skew percentiles, open-interest walls and unusually active contracts belong to unusual-options-activity. The implied move on its own, set against how a stock has actually reacted to past reports, belongs to expected-move-visualizer. What a company actually reported belongs to stock-earnings-analysis. This skill does one job, which is turning a strategy into a picture with real numbers behind it.
