About Opzun
Opzun is a free options strategy visualization and sharing tool. Build, analyze, and share options strategies in seconds — no account required.
What is a Zun?
A Zun is a shareable options strategy card. It captures your entire strategy — ticker, strikes, premiums, P&L curve, and key metrics — in a single interactive link. When you share a Zun on Discord, Twitter, or Reddit, it renders as a rich preview card. Anyone who clicks it can explore your strategy and remix it into their own Zun.
What We Do
Options strategies can be complex. Opzun makes them visual. Pick a strategy template, see the P&L curve instantly, adjust strikes by dragging on the chart, and share your analysis as a Zun with a single link.
Every Zun generates an interactive page where anyone can explore the P&L, plus a card image that renders automatically on Discord, Twitter/X, Reddit, and other platforms.
How It Works
- Real Options Data — We fetch delayed options chain data from CBOE, so premiums, IV, and Greeks reflect actual market conditions.
- Black-Scholes Math — All P&L curves, theoretical pricing, and Greeks are computed using the Black-Scholes model directly in your browser.
- Interactive Charts — Drag legs and spot price on the chart. Adjust time and IV with sliders to see how your strategy evolves.
- Instant Sharing — One click generates a shareable Zun with a preview image. No account needed.
What We Are Not
Opzun is an educational tool. We do not provide financial advice, execute trades, or connect to any brokerage. We do not recommend any specific options strategy. All data is delayed and calculations are theoretical estimates.
Data Sources
