Pick the strike, let the expiries compete
Screenshots from the live app, dark theme
A premium seller’s real question is usually not “which strategy” — it is “I would defend the 85 strike; which expiry pays me best for it?” The strike-first table answers exactly that: one strike, priced across the next four or so expiries, side by side.
Where it lives
Build a cash-secured put or covered call and a Ladder / Grid toggle appears above the ladder. Ladder is the classic view — one expiry, every strike. Grid flips the axis: your strike, every duration. Swap strategies out of the wheel family and the builder falls back to the ladder; swap back and your view choice is remembered.
Reading the columns
| Column | What it tells you |
|---|---|
| Premium | The credit at that expiry, from the chain. |
| Annualized | The premium as a yearly rate on the collateral — comparable across durations. |
| Delta | Roughly the chance the option finishes in the money. |
| $/day | Premium divided by days to expiry — the income-per-calendar-day lens. |
| Breakeven | Kind-aware: a CSP shows the effective basis if assigned; a covered call shows the if-called return. |
| Liquidity | Volume and open interest at that contract. Thin markets get flagged. |
