🧮 Options Calculator
The Options Calculator is a strategy builder for live option chains. Pick a ticker, choose an expiry, start from a preset or custom legs, then inspect payoff, P/L heatmap, greeks, IV shift and price range in one place.

Options Calculator — strategy builder, payoff chart, and P/L heatmap
Build a Position#
- Symbol strip — uses your current app ticker and loads the latest chain snapshot.
- Expiry selector — switches the active option chain without leaving the page.
- Preset menu — starts from common structures such as verticals, calendars, straddles, strangles, covered calls and protective puts.
- Leg builder — add, edit, buy/sell, resize or remove legs; stock legs are supported alongside calls and puts.
Analyze the Payoff#
- Payoff chart — shows expiration payoff and scenario P/L across the selected price range.
- P/L heatmap — scans price versus date so time decay and convexity are visible at a glance.
- Scenario controls — shift IV and price range without losing the current strategy.
- Metrics bar — summarizes premium, max profit/loss, breakevens and position greeks where available.
Market Context#
The context panel derives a short regime read from the same chain: ATM IV, term structure, put/call open interest, gamma flip and liquidity. Treat it as a sanity check for the strategy, not a signal to enter a trade by itself.
The calculator mirrors its state into the URL with compact query params. Links can preserve expiry, legs, IV shift, price range and preset choice while keeping the app shell mounted.
🔑 Key Takeaways
- Build multi-leg strategies from live chain data or presets
- Switch between payoff chart and P/L heatmap for scenario analysis
- Use IV shift and price range controls to stress-test assumptions
- Shareable URL params preserve the current calculator state
