Options visualization
ThetaViz
A focused options visualization workspace: chains, quotes, and payoff context—built as a clean, standalone product with no ties to third-party site clones.
Multi-leg builder
Model spreads, straddles, and custom legs with payoff charts and break-evens.
Market data
Chains load through ThetaViz server APIs with Massive (Polygon) and Yahoo Finance fallback.
Education first
Plain-language risk context—ideal for learning how strategies behave before you trade.
Data sources
Quotes and chains are fetched server-side. We prefer Massive (Polygon) market data when your API key allows; Yahoo Finance is used as a secondary source when rate limits or gaps require it. Always verify prices with your broker.
