How it works

Sell the front strangle, own a wider back strangle: front theta pays while the back legs cap the tails at front expiry.

When to use it

Range thesis plus a view that front IV is rich versus back.

Risks & management

Vega-heavy: back-leg IV dropping hurts everywhere on the curve. Manage at front expiry — the second cycle is a new decision.
