Barchart vs. Dedicated Covered Call Screeners: Which Tool Actually Finds Better Trades?

The Short Answer: Barchart Works, But It Has Real Limits

Barchart is good enough to get started with covered call screening, but it is not purpose-built for the job. It gives you free access to options chains, implied volatility rankings, and basic filters — which is more than most brokers offer on a single screen. However, if you are selling covered calls regularly, a dedicated screener will save you time, cut down on manual math, and surface opportunities Barchart's general-purpose layout buries.

The honest answer depends on how many positions you manage and how much your time is worth. A trader running two or three covered calls a year can get by with Barchart. A trader rolling five to fifteen positions a month will hit Barchart's ceiling fast.

What Barchart Actually Gives You for Free

Barchart's free tier includes real-time options chains, implied volatility (IV) percentile and rank scores, volume and open interest data, and a basic screener under the 'Options' tab. The IV rank feature is genuinely useful — it tells you whether current IV is high or low relative to the past 52 weeks, which matters a lot when you are selling premium. High IV rank means fatter premiums.

The free screener lets you filter by underlying price, volume, and a handful of options metrics. You can sort an options chain by expiration and strike, calculate a rough premium yield manually, and check the bid-ask spread before you place a trade. For a single stock you already own, this workflow is manageable.

Barchart's paid tier (Barchart Premier, roughly $19–$39/month depending on the plan) adds more screener columns, downloadable data, and faster refresh rates. Even at the paid level, the tool is designed for general options traders, not specifically for covered call income writers.

Where Barchart Falls Short for Covered Call Writers

Here is where the friction shows up in practice. Suppose you own 100 shares of AAPL, currently trading around $213. You want to sell a 30-day out-of-the-money call, targeting a 1.5% to 2% monthly premium yield without giving up too much upside. On Barchart, you would:

1. Navigate to AAPL's options chain. 2. Pick an expiration roughly 30 days out. 3. Scroll through strikes above $213 — say the $220 and $225 strikes. 4. Note the bid prices: the $220 call might show a $2.85 bid, the $225 call a $1.60 bid. 5. Manually calculate annualized return: ($2.85 / $213) × (365 / 30) = roughly 16.3% annualized for the $220 strike. 6. Check delta manually — the $220 call might show a 0.32 delta, meaning roughly a 32% chance of finishing in the money at expiration, per standard options theory as explained by the Options Industry Council (OIC).

That is five to six manual steps for one stock. Now multiply that across a watchlist of 20 names. Barchart does not let you screen across all optionable stocks simultaneously for annualized covered call yield, probability of expiring worthless, and bid-ask spread tightness in a single filtered view. You are doing the math stock by stock.

Dedicated covered call screeners — platforms built specifically for income writers — pre-calculate annualized return on the covered call, days to expiration, delta, probability out-of-the-money, and downside protection in one sortable table. You set your filters (minimum annualized yield, maximum delta, minimum open interest) and the screener returns a ranked list in seconds.

A Side-by-Side Comparison on a Real Trade

Let's use MSFT, trading around $430, to make this concrete.

On Barchart (free), you navigate to the options chain, select the expiration 28 days out, and find the $440 strike call with a $3.20 bid. You manually compute: ($3.20 / $430) = 0.74% for 28 days, or about 9.7% annualized. Delta reads 0.28. Bid-ask spread is $3.20 / $3.30 — tight, which is good. You also want to check that open interest is above 500 contracts to ensure liquidity, per FINRA guidance on evaluating options liquidity before trading. All of this takes roughly four to six minutes per ticker.

On a dedicated covered call screener, you set filters: stock price $50–$500, annualized yield above 8%, delta below 0.35, open interest above 500, days to expiration 21–45. MSFT's $440 call appears in the results table already showing 9.7% annualized, 0.28 delta, 28 DTE, $3.20 bid, and a downside protection figure of 2.3% (how far MSFT can fall before your net position loses money). The same information, delivered in under 30 seconds across your entire watchlist.

The time difference compounds. If you screen 20 stocks weekly, Barchart costs you roughly 80–120 minutes. A dedicated tool costs you 10–15 minutes. Over a year, that is 50+ hours of manual work versus a subscription fee that typically runs $20–$80/month for retail-grade dedicated screeners.

Risks You Need to Understand Before Trusting Any Screener

No screener — Barchart or otherwise — removes the core risks of selling covered calls. These risks are real and worth naming plainly.

Assignment risk: If the stock closes above your strike at expiration, your shares get called away. The OIC notes that American-style equity options (which cover most US-listed stocks) can be exercised early, particularly around ex-dividend dates. A screener will not warn you that AAPL goes ex-dividend two days before your expiration.

Opportunity cost: Selling a covered call caps your upside. If NVDA jumps 15% in a month and you sold a call at a 5% out-of-the-money strike, you miss most of that gain. Screeners optimize for yield, not for protecting your upside in a fast-moving stock.

Bid-ask spread risk: Screeners pull mid-price or last-trade data. In thinly traded names, you may not be able to fill at the displayed premium. Always check the actual bid, not the mid. FINRA recommends reviewing options liquidity — open interest and daily volume — before entering any options position.

Tax treatment: In the US, premiums received from selling covered calls are generally not taxed until the position closes, but the rules get complicated fast with qualified covered calls and holding periods. The IRS Publication 550 covers investment income and expenses, including options. In Canada, the CRA treats options premiums as either income or capital gains depending on your trading frequency and intent — consult a tax professional before scaling up.

Data latency: Barchart's free tier has a 15-minute delay on some data. Even paid screeners may not show real-time Greeks during fast-moving markets. Always confirm fills in your brokerage platform.

Who Should Stick With Barchart and Who Should Upgrade

Stick with Barchart if you own fewer than five positions, sell covered calls only a few times a year, are still learning how options chains work, or simply do not want another subscription. Barchart's free options chain and IV rank data are genuinely useful for occasional traders, and the learning curve is low.

Consider a dedicated screener if you manage a covered call portfolio of five or more positions, roll positions monthly or more frequently, want to screen across the entire optionable universe rather than just your current holdings, or find yourself spending more than 30 minutes per week on manual screening math.

The break-even math is straightforward. If a dedicated screener costs $40/month and saves you three hours of screening time monthly, you need to value your time at roughly $13/hour for it to pay off in time savings alone — before counting any improvement in trade quality from better filtering.

The Bottom Line on Barchart for Covered Calls

Barchart is a legitimate, well-maintained platform with real options data and useful IV metrics. It is not a toy. But it was built for a broad audience of options traders, not specifically for covered call income writers who need annualized yield, downside protection, and probability-of-expiry calculations pre-built into a sortable screener.

Use Barchart to learn the mechanics, verify data, and check IV rank before you sell. Use a dedicated covered call screener to find the trades efficiently once you are running a real portfolio. The two tools are not competitors — they are different layers of the same workflow.

Is Barchart free for options screening?

Barchart offers a free tier that includes real-time options chains, IV rank, volume, and open interest data. The free screener has limited filter options compared to the paid Premier tier, which runs roughly $19–$39 per month. For basic covered call research on a small watchlist, the free version is functional.

What does a dedicated covered call screener do that Barchart doesn't?

Dedicated covered call screeners pre-calculate annualized premium yield, downside protection percentage, probability of expiring out of the money, and delta across all optionable stocks simultaneously. Barchart requires you to calculate these figures manually for each ticker. The time savings become significant once you are managing five or more positions.

How do I calculate annualized covered call return manually on Barchart?

Divide the option bid price by the current stock price, then multiply by 365 divided by the days to expiration. For example, a $2.85 premium on a $213 stock with 30 days to expiration equals ($2.85 / $213) × (365 / 30), or roughly 16.3% annualized. Always use the bid price, not the mid or ask, since that is what you will realistically receive.

Can Barchart screen for covered calls across my whole watchlist at once?

Barchart's screener can filter optionable stocks by broad criteria like price range and volume, but it does not natively rank results by covered call annualized yield or downside protection across a custom watchlist. You would need to check each ticker's options chain individually. Dedicated covered call screeners solve this by scanning the full optionable universe with income-specific filters.

Does selling covered calls affect my taxes in the US or Canada?

In the US, the IRS treats covered call premiums as short-term capital gains in most cases, but qualified covered call rules under IRS Publication 550 can affect the holding period of your underlying shares. In Canada, the CRA may treat premiums as income or capital gains depending on your trading frequency and intent. Consult a qualified tax professional before scaling your covered call activity.

What open interest level should I look for before selling a covered call?

Most experienced covered call writers look for at least 100 to 500 contracts of open interest at the specific strike and expiration they plan to trade. Higher open interest generally means tighter bid-ask spreads and easier fills, which directly affects the premium you actually collect. FINRA recommends reviewing liquidity metrics like open interest and daily volume before entering any options position.
