Buffer- and quality-aware ranking — not yield-chasing. The amber ⚠ badge flags an earnings report inside the trade window; contracts exposed to earnings are treated more cautiously, and some are left out.

PutFinder helps you answer

  • → Which put setup is worth looking at today?
  • → Which strike best balances premium and downside buffer?
  • → Which expiration is more efficient on a premium-per-day basis?
  • → Is the premium elevated because of earnings risk?
  • → How far can the stock fall before break-even?

The method is explained in plain terms. Every run is timestamped. Results are never deleted.

Results now stand on timestamped receipts recorded before the outcomes were known — see /performance — not cherry-picked screenshots.

Who it's for

You sell cash-secured puts. The daily screen is the chore.

Every evening it’s the same pass: flipping through option chains, weighing premium against downside, checking earnings dates, second-guessing whether the yield justifies the risk. PutFinder runs that pass for you across a curated universe — and shows every number behind the ranking.

Systematic CSP sellers
You already trade cash-secured puts and want the same rules applied the same way every day — not a fresh gut call each day.
Premium-vs-risk researchers
You care less about a hot tip and more about why one setup ranks above another. The method is explained in plain terms, and every input is shown next to the rank.
Forward-testers
You want a timestamped daily record to test a methodology against — not cherry-picked screenshots assembled after the fact.

Not the right fit if you want trade alerts, a win-rate guarantee, or someone to tell you what to buy. PutFinder ranks and documents — the decision stays with you.

How it works

Consistent rules, every day, no surprises.

The same rule set runs on a fixed schedule each day, with a second update before the close for Plus. Method explained in plain terms, every input shown next to the rank.

The approach
Three plain steps

PutFinder is a screening engine, not a crystal ball. It surfaces setups worth researching — you decide what to do with them.

1
Scan a hand-curated universe of liquid US names each day
The universe itself is chosen by a human, not a formula — an operator-maintained, audited list of liquid names. Every contract within it still has to clear its own bid-ask-spread and open-interest gates before it is scored.
2
Rank every eligible CSP setup on premium-vs-risk
Each setup is looked at for the kind of stock it is, how attractive the premium is for the room it leaves, and upcoming event risk. The rules are applied consistently.
3
Save a durable daily snapshot for forward-testing
As contracts expire, each is settled against the close and compared to the rank it carried before the outcome was known — that comparison is what /performance renders.
Method explained in plain terms, every input shown next to the rank. See how the method works.

Theta decay & probability density
PANEL A · THETA DECAY TIME VALUE TIME TO EXPIRY T0 Expiry ~30 DTE Th PANEL B · PROB. DENSITY UNDERLYING PRICE AT EXPIRY Strike K Price S OTM tail PoP = 1-|d| (model est.)

Panel A: option time value erodes convexly toward zero at expiry (Θ decay). Panel B: risk-neutral price density at expiry; OTM tail = probability of closing below strike K. PoP ≈ 1−|Δ| is a model-estimated probability derived from Black–Scholes delta, not a historical win rate. Illustrative — not actual data.

Pipeline
Screening pipeline

One eligibility gate, then a few angles looked at together.

Liquidity Gate
Only contracts that can be traded in practice get through: out-of-the-money puts with a real two-sided market, enough trading interest, a reasonable bid-ask gap and a suitable expiration window.
Stock Quality Score
Looks at how suitable the stock is for selling a put right now — its profile, how richly its options are priced, and its recent trend. Not a stock-quality grade. Stale or missing data excludes the ticker.
Contract Fit Score
Weighs the premium against the room the stock has to fall before it reaches the strike.
Earnings Gate
Considers how close an earnings report falls to expiration. Contracts exposed to one are treated more cautiously, and some are left out.
Scope
What it is. What it is not.

The non-advisory boundary is a design feature, not a disclaimer.

Is
  • Relative ranking of CSP setups, today
  • Durable daily snapshots for forward-testing
  • Method explained, every input shown
  • Research tool for methodical discipline
  • A heuristic that ranks, not a predictor
Is Not
  • A trading signal or execution system
  • Financial advice or a recommendation
  • A win-rate machine — delta is a model estimate, not a win rate
  • A return predictor — yield is arithmetic on premium

A score of 94/100 means “ranks near the top of today’s pool” — not “a 94-quality investment.”

Research Record

Research Lifecycle

Methodology first, receipts second, claims third — each step timestamped and verifiable.

Open Methodology

Published

The method is explained in plain terms on the methodology page, and every input is shown next to the rank.

Daily Timestamped Snapshots

Recording Daily

A timestamped snapshot of every daily Top 10 ranking is recorded before market outcomes are known, creating a permanent historical dataset.

Continuous Forward Validation

Updated Daily

Every ranked pick is settled against recorded prices and published on the Performance page: settled counts, and a cohort comparison against the full qualified pool and a yield-only baseline, updated daily. All figures are hypothetical, before costs, and not a forecast. View the settlement record →

Questions

Straight answers before you sign up.

How is this different from a signals service or a Discord?

Signal services tell you what to trade. PutFinder does not: it ranks cash-secured put setups every day (with per-ticker covered call analysis alongside) and shows the inputs behind each row, so you can judge it yourself. No alerts, no “trade now” — a ranking you can inspect and disagree with. See how the method works.

Where does the data come from?

Option chains from a market-data provider, with every figure derived from stored raw inputs and a recorded Black–Scholes estimate where a delta is missing. Nothing is fabricated.

Is there a performance track record yet?

Yes — an early one. The /performance page is live now and shows how each day’s ranked picks actually resolved, including a cohort comparison against a zero-skill baseline, updated daily. It’s still a small, early, all-hypothetical sample (marked at the close mid, not real fills) — described honestly, with no performance claims beyond what the settled data shows. A fuller, forward-validated record keeps accumulating.

Is this investment advice?

No. PutFinder is a relative ranking heuristic — not a recommendation, return predictor, or win-rate machine. A high score means “ranks near the top of today’s pool,” nothing more. You make every decision.

What happens if the stock falls — can I lose money?

Yes. Selling a cash-secured put obligates you to buy 100 shares at the strike if the stock is below it at expiration. Your loss below the breakeven (strike − premium) is the same as owning the shares from that price — there is no floor short of zero. The Buffer% column is the distance to the strike as of the run, not protection: it does not stop a gap, and PutFinder never claims a setup is safe. A high score means a setup ranks near the top of today's pool on premium-vs-risk — it says nothing about whether this particular trade will resolve in your favour.

Why only a curated universe of names?

Liquidity. The universe is deliberately limited to liquid US names where bid-ask spreads are tight and fills are realistic — screening illiquid options produces ranks you can’t actually act on.
