About OptX

OptX is a free, no-signup options strategy analyzer built for retail traders who want professional-grade tools without the professional-grade price tag.

The Mission

Most options analysis tools cost $10-30/month, gatekeeping features that retail traders need to make informed decisions. OptX is our answer — a completely free, browser-based alternative with institutional-grade analytics.

What Makes OptX Different

• 100% Free — No signup, no trial, no credit card. Forever.
• 24 Strategy Presets — From simple long calls to complex iron condors, butterflies, and ratio spreads.
• Live Greeks — Delta, gamma, theta, vega for every contract, refreshed every 30 seconds.
• P&L Heatmap — Visualize profit and loss across every price and every day until expiration.
• Probability of Profit — Statistical POP based on implied volatility and time.
• Real-time What-If — IV slider, target price slider, and three payoff lines (today, midway, expiration).

Built for Serious Traders

OptX was built by traders, for traders. We combine the analytical depth of tastytrade and thinkorswim with the clean UI of modern web apps. Every feature is designed to help you make better trading decisions.

Data & Transparency

All options data is sourced from Alpaca Markets. P&L and Greeks calculations use industry-standard Black-Scholes pricing. Probability of profit uses a log-normal distribution model. We're transparent about our methodology — see tooltips throughout the app for explanations.

The Technology

OptX is built with Python (FastAPI), PostgreSQL, and modern web standards. It's designed to be fast, reliable, and accessible on any device. Open architecture means we can add new features quickly based on user feedback.
