Wheel Strategy Screener: How to Find Cash-Secured Put Candidates for Free

A Wheel strategy screener does one job: shrink thousands of tickers down to a handful of stocks you would be glad to own, with options liquid enough to trade, so you can sell cash-secured puts on them. You do not need a paid scanner for that. A free stock screener plus your broker's option chain covers it, as long as you screen in the right order and know which "great" results to throw out.

The short version

Screen the stock first, the option second. Premium is the last filter, not the first.
Stock filters: a share price that fits your cash, high trading volume, listed options, a business or fund you understand, and no earnings report before your expiration.
Option filters: plenty of open interest, a tight bid-ask spread, a strike you would happily buy at, and a premium worth the cash it ties up.
Throw out outliers. A put that pays far more than its neighbors is usually pricing in news you have not read yet.

Stage 1: the stock screen

Most free stock screeners can filter by price, average volume, market cap and sector, and many can show whether a stock has listed options and when the next earnings date is. These starting ranges are a reasonable first pass. Adjust them to your account.

Filter	Starting point	Why it matters for the Wheel
Share price	Strike × 100 fits within about 5% to 10% of your account	One put ties up cash for 100 shares. A $40 strike needs $4,000; an $80 strike needs $8,000.
Average daily volume	Over 1 million shares	Busy stocks tend to have busy, tighter option markets.
Market cap	Mid cap and up, or a large, broad ETF	Larger companies are less likely to gap on a single headline.
Optionable	Yes, with weekly or monthly expirations	No listed options, no Wheel.
Next earnings date	After your planned expiration	Earnings can move a stock far past your strike overnight.
Your own judgment	Would you hold it for a year if assigned?	Assignment is a normal outcome of the Wheel, not a failure.

That last row is the one no screener can run for you. For how to judge it, see how to pick stocks for the Wheel, and if you would rather avoid single-company risk, the best ETFs for the Wheel.

Stage 2: the option-chain screen

Open the option chain for each name that passed Stage 1 and look at puts about 30 to 45 days out. This is where a free broker chain is all you need.

Check	Starting point	What it tells you
Delta	About 0.20 to 0.30	A rough gauge of how likely the put is to finish in the money.
Open interest	Several hundred contracts or more at your strike	Other traders are active there, so fills and rolls are easier.
Bid-ask spread	A few cents, or under about 5% of the premium	Wide spreads quietly take a slice of every trade. See placing the order.
Implied volatility	Higher than the stock's usual level, but not extreme	Explains why a premium is rich. See implied volatility and the Wheel.
Return on cash	Premium ÷ strike, then annualized	Puts different strikes and expirations on the same clock.
Breakeven	Strike − premium	Your effective purchase price if assigned. Would you buy the stock there today?

Worked example: three screener results

Hypothetical example. Made-up stocks and round numbers for illustration only, not quotes, recommendations or typical results. Commissions are left out.

A trader with a $50,000 account runs the screen and gets three names, each with a 30-day put near 0.25 delta.

	Stock A	Stock B	Stock C
Put strike / premium	$40 / $0.60	$25 / $0.90	$80 / $1.10
Cash secured	$4,000	$2,500	$8,000
Return on cash (30 days)	1.5%	3.6%	1.375%
Annualized	about 18.2%	about 43.8%	about 16.7%
Breakeven if assigned	$39.40	$24.10	$78.90
Earnings before expiration?	No	Yes, in 9 days	No
Bid-ask spread	$0.58–$0.62	$0.80–$1.00	$1.05–$1.15

Stock B tops a sort by premium, and it is the one to drop. Its yield is more than double the others because an earnings report lands inside the trade, and its 20-cent spread means a fill near the bid costs a meaningful slice of the premium. Stock A pays a little more on cash than C and ties up half as much, so it leaves room to spread the account across more names. Stock C is still reasonable if the trader prefers that company, but at $8,000 it is 16% of a $50,000 account, above the 5% to 10% sizing range used in Stage 1.

The screener did its job by surfacing three candidates. The decision came from earnings dates, spreads, position size and whether the breakeven is a price the trader would gladly pay.

Red flags that a screener will happily show you

An unusually high premium. It usually means earnings, a pending decision, a takeover rumor or a stock already falling. Read the news before you sell.
A stock trading near its 52-week low after a sharp drop. Premium is rich because the market expects more movement, possibly lower. See the Wheel in a bear market.
Leveraged or inverse ETFs. Their premiums look great, but they behave differently from ordinary stocks when held. See leveraged ETFs and the Wheel.
Thin option chains. Low open interest and wide spreads make it hard to close or roll at a fair price.
Low-priced stocks picked only because they fit a small account. A cheap stock is not a safe one. See the Wheel with a small account for better options.

A weekly screening routine

Rerun your Stage 1 stock screen once a week and update a watchlist of 10 to 20 names.
Remove any name with earnings before your next expiration, a broken business story or a widening option spread.
For the rest, note the 30 to 45 day put around 0.20 to 0.30 delta, its premium, spread and breakeven.
Compare the finalists on the same clock in the Wheel calculator.
Sell puts only on the names you would buy at the breakeven, sized within your limits, and record each trade in the free Wheel tracker.

Screening is only the first step of the Wheel. Strikes, rolls, assignment and covered calls all come after it, and Spin the Wheel, Cash the Checks walks through every one of them step by step.

FAQ

What is the best free screener for the Wheel strategy?

There is no single best one. Any free stock screener that filters by share price, average volume, market cap and whether a stock has listed options will handle the first pass, and your broker's option chain handles the second. The filters you choose matter more than the tool.

Should I just sort a put screener by highest premium?

No. The highest premiums usually belong to stocks with an earnings report, a pending event or a falling price inside the expiration window. Sort by premium only after you have filtered for stocks you would be happy to own, liquid options and no binary event before expiration.

What delta should a cash-secured put screener use?

Many Wheel traders start with puts around 0.20 to 0.30 delta, roughly 30 to 45 days out. That is a starting range, not a rule. Lower delta means less premium and less chance of assignment; higher delta means more premium and more chance of owning the shares.

How many stocks should a Wheel watchlist have?

Usually fewer than people expect. Ten to twenty names you understand, refreshed by a weekly screen, is easier to manage than a hundred tickers you barely know.

Can a screener tell me whether a put is a good trade?

No. A screener finds candidates. Whether a trade is good depends on whether you want the shares at the breakeven price, how the trade fits your account size and what you plan to do if you are assigned.
