A cash-secured put screener that ranks by what you keep

What a good CSP screen actually filters

A cash-secured put is a promise: reserve the cash, take the shares if assigned. A useful screener therefore filters on the seller's real constraints, not just "high IV":

• Delta band — how close to the money you're willing to promise; most sellers live between 0.15 and 0.35
• DTE window — the 30–45 day sweet spot where theta decay is steepest, or shorter if you manage actively
• Open interest and minimum bid — liquidity so the fill is real and the exit is possible
• Annualized return on collateral — premium ÷ strike ÷ days × 365, so every candidate compares apples to apples

Two filters most screeners don't have

Earnings blackout. A rich put the week before earnings isn't premium, it's a coin flip. ThetaIQ flags candidates whose earnings land before expiry, so you can skip them — or sell them deliberately, eyes open.

Leveraged-ETF skip. 2x and 3x funds carry structural decay that keeps their premiums permanently rich, so they crowd the top of every premium scan. If you'd never hold SOXL through assignment — and you shouldn't — one checkbox removes them and ~160 of their cousins from every result.

Premium first, then quality control

The screener answers "what pays?" — not "should I own it?". A 40% annualized yield on a company with deteriorating fundamentals is a trap with good marketing. Run the candidate through ThetaIQ's Consistency Rating (A–F from fundamentals, earnings beats and insider behavior) before you sell, and track the result in your wheel campaigns after. Screen, verify, sell, track — that's the loop.
