Cash-Secured Put Scanner: Find High-Probability Wheel Strategy Opportunities

Discover CSPs with the best risk-adjusted annualized returns

Manually screening for cash-secured puts takes hours. You're scrolling through hundreds of option chains, calculating annualized returns in spreadsheets, and guessing at assignment risk—while the best opportunities expire before you act. Our cash-secured put scanner does the heavy lifting. Enter your tickers and it scans their live option chains, filtered by your criteria.

Frequently Asked Questions

Everything you need to know about getting started

What makes a cash-secured put scanner different from a regular options scanner?

A cash-secured put scanner is specifically optimized for income-focused traders. Instead of just showing bid/ask prices, it calculates annualized returns, assignment probabilities, and capital requirements—metrics that matter for CSP strategies. The same scanner has a covered call tab, so you can plan both sides of the wheel in one place.

How does assignment probability work in your CSP scanner?

Assignment probability is the estimated chance the put finishes in-the-money at expiration. We use the delta supplied by our market data provider when it is available, and otherwise the Black-Scholes N(d2) probability from the contract's own implied volatility. Use it to choose between aggressive income (higher probability) and conservative ownership (lower probability) strategies.

Can I backtest my CSP screening criteria before trading?

Yes, as a simulation (Portfolio). From any result you can backtest selling puts on that ticker at a fixed distance below the price (OTM %) and DTE over the past 2 years, including how often those puts would have been assigned. Premiums are modeled with Black-Scholes from historical stock prices and realized volatility, not historical option quotes, so treat the results as theoretical. It is a quick way to sanity-check return expectations before putting capital at risk.

What filters are available in the CSP scanner?

Filter by days to expiration (preset ranges from 0-DTE to 60 days), strike range (OTM, ATM, ITM), liquidity (minimum volume and liquidity score), and a minimum and maximum assignment probability. Results are ranked by a score that weighs annualized return against assignment probability, and in the Compare view you can further filter and sort by annualized return, 7-day ROI, OTM %, IV percentile, RSI, moving-average distance, and more.

Does this work for the wheel strategy?

Yes. When you sync your brokerage account, an assigned put shows up as a new stock position, the portfolio scan suggests covered calls against it, and wheel analytics track each cycle from put to called-away shares.
