Presets

Center strike

An option strategy's payoff diagram plots profit or loss against the underlying price at expiration. Combining calls and puts at different strikes shapes the curve — capping risk, capturing volatility, or generating income. Educational tool, not investment advice.

Governing equation

Π (S) = i \sum q_{i} [max (S - K_{i}, 0)_{call}, max (K_{i} - S, 0)_{put} - p_{i}], K = 100

Reading this result: Both profit and loss are capped, so this is a defined-risk position — you trade unlimited upside for a known worst case.
