VolRadar vs Covered Call Pro: Which Screener Finds Better High-IV Covered Call Trades?

The Short Answer Before We Dig In

If you already own stocks and want a fast, purpose-built tool for selling covered calls on high implied-volatility names, Covered Call Pro is designed specifically for that job. VolRadar is a broader volatility-analysis platform that serves options traders of all types — including buyers, spread traders, and volatility researchers — which means covered-call sellers get a lot of features they will never use. Both tools surface elevated IV, but they frame the data differently, and that difference matters when you are trying to make a quick, confident decision about which strike to sell this week.

This comparison walks through what each platform actually shows you, runs a real NVDA example through both workflows, and gives you an honest look at where each tool falls short.

What 'High IV' Actually Means for a Covered-Call Seller

Before comparing screeners, it helps to be precise about the metric. Raw implied volatility — say, NVDA's 30-day IV sitting at 52% — tells you the market is pricing in large moves. But 52% is only meaningful if you know whether that is high or low relative to NVDA's own history. That is why most serious covered-call traders focus on IV Rank (IVR) or IV Percentile rather than raw IV alone.

IV Rank compares today's IV to the stock's 52-week high and low IV. A rank of 80 means current IV is near the top of its one-year range — a potentially good time to sell premium. The Options Industry Council (OIC) explains this concept in its free educational materials and recommends that new options sellers understand both metrics before entering trades.

A good screener should surface IVR, not just raw IV, and it should let you filter by it. Both VolRadar and Covered Call Pro do this — but they present it in very different ways.

How VolRadar Approaches the Screener Problem

VolRadar was built for volatility traders broadly. Its core strength is a detailed volatility surface — you can see the full term structure, skew charts, and historical IV cones for any ticker. For a sophisticated trader who wants to understand why IV is elevated (earnings, macro event, sector rotation), those charts are genuinely useful.

For a covered-call seller, though, the workflow is longer. You typically start with a watchlist or a manual ticker search, pull up the vol surface, check IVR, then navigate to the options chain to find your strike. There is no single-screen view that says: 'Here are the 10 stocks in your portfolio where IV Rank is above 60 and the 30-delta call is paying more than 2% for the week.' You have to build that view yourself.

VolRadar also includes a screener tab that lets you filter by IVR, sector, and market cap. It works, but the output is a broad universe of tickers — not filtered to stocks you already own. For a buy-and-hold investor running covered calls on a 15-stock portfolio, that broad output adds noise rather than reducing it.

Pricing for VolRadar sits in the $40–$60/month range depending on the tier, as of mid-2025. FINRA reminds investors to evaluate whether any subscription tool's cost is proportionate to the income it helps generate — a fair benchmark to apply here.

How Covered Call Pro Approaches the Screener Problem

Covered Call Pro is built around one specific workflow: you own shares, you want to sell calls, you want to find the best strike and expiration right now. The screener lets you input your existing holdings and immediately ranks them by IV Rank, premium yield (premium divided by stock price), and days to expiration. The output is a short, prioritized list — not a 200-row spreadsheet.

The platform also flags earnings dates automatically, which matters because selling a covered call into an earnings announcement can expose you to a large gap move that blows through your strike. The SEC has noted in investor guidance that earnings-related volatility is one of the most common surprises for new options sellers.

Covered Call Pro's strike-selection tool shows you the annualized yield at each delta level (typically 20-delta through 40-delta for income-focused sellers), so you can compare a conservative 20-delta call against a more aggressive 35-delta call in seconds. The platform does not offer deep volatility-surface analysis or skew charts — if you want to study term structure, you will need a supplementary tool.

A Real Trade Example: NVDA Covered Call Through Each Workflow

Let's say it is a Tuesday morning. You own 100 shares of NVDA, currently trading at $138.50. You want to sell a weekly or monthly covered call.

Using VolRadar: You search NVDA manually, open the volatility dashboard, and see 30-day IV at 58% with an IVR of 74. You navigate to the options chain, filter for the nearest Friday expiration, and scan the strikes. The $145 call (roughly 30-delta) is showing a bid of $2.10, ask of $2.20. You note the mid is $2.15. That is a 1.55% yield on your $138.50 cost basis for one week. You check the skew chart to see if put skew is elevated — it is, which confirms the market is pricing in downside risk, not just upside. Total time: 6–9 minutes if you know the platform.

Using Covered Call Pro: NVDA appears near the top of your portfolio screener because IVR is 74 — flagged automatically. The tool shows you three strike options for the nearest expiration: $143 call (38-delta, $2.85 bid, 2.06% weekly yield), $145 call (30-delta, $2.15 bid, 1.55% weekly yield), $148 call (22-delta, $1.40 bid, 1.01% weekly yield). An earnings flag shows no announcement within 14 days, so the expiration is clean. You pick the $145 call, matching your risk tolerance. Total time: 90 seconds.

The VolRadar workflow gives you more context. The Covered Call Pro workflow gives you a faster, cleaner decision. Which matters more depends on how you trade.

Honest Risks You Need to Know Before Using Either Tool

No screener eliminates the core risks of covered-call writing, and it would be misleading to suggest otherwise.

Capped upside is real. If NVDA jumps from $138.50 to $160 before expiration, you sell your shares at $145 (your strike) and miss $15 of gain. The $2.15 premium you collected does not come close to covering that opportunity cost. The OIC's covered-call educational module covers this trade-off in detail and is worth reading before you sell your first call.

High IV is often high for a reason. When a stock's IV Rank is 80+, the market is pricing in uncertainty — a product launch, a legal issue, a macro event. Selling premium into that uncertainty means you are being paid to take on that risk. Both screeners will surface these names, but neither will tell you whether the risk is worth taking.

Tax treatment matters. In the US, premiums received from selling covered calls are generally treated as short-term capital gains, but the rules around qualified covered calls and holding periods are specific. The IRS Publication 550 covers investment income and expenses, including options. Canadian investors should consult CRA guidance on options income, as treatment can differ depending on whether the CRA classifies your activity as business income or capital gains.

A screener is a starting point, not a recommendation. FINRA's investor education resources emphasize that tools and platforms do not substitute for understanding the instrument you are trading.

Side-by-Side Feature Comparison

Here is a plain summary of how the two platforms stack up on the features that matter most to covered-call income sellers:

Portfolio-based filtering: Covered Call Pro — yes, core feature. VolRadar — limited, requires manual setup.

IV Rank / IV Percentile display: Both — yes.

Earnings date flagging: Covered Call Pro — yes, automatic. VolRadar — yes, but requires separate check.

Annualized yield by strike: Covered Call Pro — yes, built into strike selector. VolRadar — no, must calculate manually.

Volatility surface and skew charts: VolRadar — yes, detailed. Covered Call Pro — no.

Term structure analysis: VolRadar — yes. Covered Call Pro — no.

Learning curve for new sellers: Covered Call Pro — low. VolRadar — moderate to high.

Approximate monthly cost (mid-2025): Covered Call Pro — $29/month. VolRadar — $40–$60/month.

Best fit: Covered Call Pro — buy-and-hold investors selling calls on existing positions. VolRadar — active options traders who also write covered calls as one of several strategies.

Which Tool Should You Actually Use?

If your primary goal is to generate consistent income from stocks you already own, and you want to spend 10 minutes or less per week on strike selection, Covered Call Pro is the more efficient tool. The portfolio-first workflow, automatic earnings flags, and yield-by-strike display are built for exactly that use case.

If you are an active trader who also sells covered calls but wants deep volatility analysis, skew data, and term-structure charts to inform a broader options strategy, VolRadar gives you more analytical depth — at a higher price and with a steeper learning curve.

Some traders use both: Covered Call Pro for the weekly workflow and VolRadar for deeper research on specific names where they want to understand the volatility environment before committing. That is a reasonable approach if the combined subscription cost is proportionate to the premium income you are generating — a test FINRA's investor guidance implicitly encourages for any paid financial tool.

The bottom line: the best screener is the one you will actually use consistently. Complexity that sits unused is not an advantage.

Is VolRadar designed specifically for covered-call sellers?

No. VolRadar is a broad volatility-analysis platform used by options buyers, spread traders, and volatility researchers, as well as covered-call sellers. It has strong IV and skew tools but is not built around a portfolio-first, income-selling workflow. Covered-call sellers can use it effectively, but they will navigate past many features that are not relevant to their strategy.

What IV Rank should I look for when screening for covered calls?

Most income-focused covered-call sellers target stocks with an IV Rank above 50, meaning current implied volatility is in the upper half of its one-year range. A rank above 70 signals elevated premium, but it also signals elevated uncertainty — so higher IVR is not automatically better. The Options Industry Council (OIC) recommends understanding why IV is elevated before selling into it.

Can I use a free screener instead of paying for VolRadar or Covered Call Pro?

Free tools like the CBOE's options data pages and brokerage-built screeners (available at most major US brokers) can surface IV data at no cost. They typically lack portfolio-integration, automatic earnings flags, and yield-by-strike calculations, so the workflow is slower and more manual. For occasional traders, free tools may be sufficient; for weekly covered-call sellers, a paid screener usually pays for itself quickly in time saved.

How are covered-call premiums taxed in the US?

Premiums received from selling covered calls are generally treated as short-term capital gains in the year the position closes, but the rules around qualified covered calls and holding-period adjustments are specific. IRS Publication 550 covers investment income and expenses including options in detail. Consult a tax professional for guidance on your specific situation.

What happens if the stock price shoots past my strike before expiration?

If the stock closes above your strike at expiration, your shares will typically be called away at the strike price — you keep the premium but miss any gain above the strike. This capped-upside risk is the core trade-off of covered-call writing and is not eliminated by using any screener. The OIC's covered-call educational materials explain assignment mechanics in plain language.

Does Covered Call Pro work for Canadian investors?

Yes. Canadian investors can use Covered Call Pro to screen for high-IV opportunities on US-listed stocks held in taxable or registered accounts. However, Canadian investors should be aware that the CRA may treat options premium income differently from capital gains depending on trading frequency and intent — CRA guidance on derivatives and options income applies. Consulting a Canadian tax advisor before starting a covered-call program is recommended.
