Best covered call screener apps

A covered call screener is only as good as what it throws away. Most rank by yield, which reliably puts the worst chains at the top. Five tools worth looking at, what each one filters on, what it costs, and where each of them falls down.

One filter matters more than the rest and almost no screener leads with it: can you actually get filled near the mid. A 0.18 delta call showing 31 percent annualized on a chain with 40 contracts of open interest and a $0.35 wide market is not a 31 percent trade. It is whatever you net after crossing that spread, which might be half.

Read every tool below against that.

1. OptionsKing

Free. Browser today, iPhone and Android in progress.

Scores every candidate strike 0 to 100 and refuses to surface anything below 60, at any setting, with 75 the recommended bar. Liquidity and the event calendar in the expiry window feed the score rather than sitting in an optional filter you forget to tick. When nothing on your watchlist clears, it shows an empty screen and says so.

Where it falls down: 60 tickers on the public data pages, no spreads, no backtesting, and no store listing yet. On the first public snapshot, in a low-volatility tape, nothing at all cleared 75 across all 60 names. A screener that shows you nothing is a hard sell, and it is also the point.

Per-ticker covered call data is public and dated. How it works covers the gate.

2. Barchart Premier

Premier is $29.95 a month billed monthly, $199.95 for a year, or $368.00 for two years. The annual and two-year plans carry a 30-day money-back guarantee.

The widest coverage on this list by a distance, with covered call screening across thousands of names and a data business underneath it that has been running for decades. If you want to screen the whole market rather than a watchlist, this is the one.

Where it falls down: it ranks, it does not withhold. You get a table sorted how you asked, and the judgment about whether the top row is a trap stays with you.

3. Market Chameleon

Paid subscription, several named plans, limited free account.

Earnings analytics. The historical earnings-move data, the implied-versus-realized studies and the volatility screens go deeper than anything OptionsKing has or plans to build. For covered calls specifically, the value is in checking what a name has historically done through an earnings window before you write a call across one.

Where it falls down: the depth is the difficulty. There is a real learning curve, and if you want to be told which two strikes to look at, this is not that product.

4. Option Alpha

Pro runs $149 a month, or $99 a month if you pay for the year up front. Two broker promotions drop that to $0 a month if you keep a qualifying balance: $5,000 at Tradier, $10,000 at TradeStation.

Screening is almost beside the point here. The reason to pay is automation: bots that enter and exit against your rules through TradeStation, Charles Schwab, Tradier and tastytrade, plus a serious backtester.

Where it falls down: it is a lot of platform if you write four calls a month by hand, and it needs a broker connection to do the thing it is good at.

5. OptionStrat

There is a free tier on delayed data. Live Tools is $39.99 a month and Live Flow is $99.99 a month, both with a 7-day trial.

The best payoff visualization of anything listed here. Draw the position, see the shape, save the trade and track it.

Where it falls down: it is built around a directional view, and covered call screening is not what it is for.

How to judge any of them

• Does it show you the spread and the open interest at the strike? If those are not on the results row, the yield number on that row is incomplete.
• Does it know about earnings in the window? A call written across an earnings print is a different trade and a screener that ignores the date is hiding the biggest variable.
• Can it return nothing? A screener that always fills the page is telling you about its result count, not about the market.
• Does it tell you what happened afterwards? Almost none of them do. Whether the trade worked is the only question that pays.
