VolRadar vs Covered Call Pro: Which Options Screener Has Better Covered Call Filters?

The Short Answer Before We Dig In

Covered Call Pro is built from the ground up for retail investors who sell covered calls on stocks they already own. VolRadar is a broader volatility-analysis platform aimed at active options traders who want raw vol data across multiple strategies. If your only goal is finding the best covered call setups on a stock you hold, Covered Call Pro's filters get you there faster with less noise.

That said, both tools have real strengths. This review breaks down exactly where each one wins, where each one falls short, and what the difference looks like on a real trade.

What Each Platform Actually Does

VolRadar launched as a volatility-surface tool. It shows implied volatility rank (IVR), IV percentile, term structure, and skew charts across expirations. Traders who want to visualize the entire vol surface before placing a trade find it genuinely useful. The platform also flags elevated IV environments, which matters for any options seller.

Covered Call Pro is purpose-built for one job: helping you find the right strike and expiration when you want to sell a call against shares you already own. The screener filters by annualized premium yield, delta, days to expiration (DTE), bid-ask spread width, and assignment probability. Every filter maps directly to a decision a covered-call seller actually makes.

Think of it this way. VolRadar hands you a weather map of the entire atmosphere. Covered Call Pro hands you a five-day forecast for the specific city you live in.

Head-to-Head: The Filters That Matter for Covered Calls

Here are the six filters that most covered-call sellers rely on, and how each platform handles them.

**Annualized Premium Yield.** Covered Call Pro calculates this automatically for every screened result. You can sort the entire list by annualized yield and immediately see which strike-expiration combos pay the most relative to the stock price. VolRadar does not surface annualized yield as a sortable column; you calculate it manually from the premium and DTE.

**Delta.** Both platforms show delta. Covered Call Pro lets you set a hard delta ceiling — for example, show me only calls with delta below 0.30 — so you filter out strikes that carry heavy assignment risk before you even look at the list. VolRadar shows delta in its options chain view but does not offer a screener-level delta filter for covered calls specifically.

**Bid-Ask Spread Width.** Wide spreads eat your real fill price. Covered Call Pro flags contracts where the bid-ask spread exceeds a user-set percentage of the midpoint. VolRadar shows bid and ask in the chain but does not have a spread-width filter in its screener.

**IV Rank and IV Percentile.** VolRadar wins here. Its IVR and IV percentile data is detailed, historically deep, and visually clear. Covered Call Pro shows IVR for each screened stock but does not offer the same depth of vol-surface visualization.

**Earnings Date Warning.** Covered Call Pro flags when an earnings announcement falls inside your chosen expiration window. Selling a covered call through earnings is a known risk — the stock can gap down sharply, leaving you with a loss that the premium does not cover. VolRadar does not surface earnings-date warnings in its screener output.

**Assignment Probability.** Covered Call Pro shows the probability of the call expiring in the money, derived from the option's delta. VolRadar shows delta but does not translate it into a plain-English assignment probability label the way Covered Call Pro does.

A Worked Example: Selling a Covered Call on AAPL

Let's say you own 100 shares of Apple (AAPL) at a current price of $213.50. You want to sell a covered call expiring in roughly 30 days and you want to keep assignment risk low — delta under 0.30.

In Covered Call Pro, you enter AAPL, set DTE between 25 and 35 days, set delta maximum at 0.30, and set minimum annualized yield at 10%. The screener returns a short list. Near the top: the $225 strike expiring in 30 days, bid $1.85, ask $1.95, midpoint $1.90, delta 0.24, annualized yield 10.8%, IVR 52.

You collect $190 in premium per contract (100 shares × $1.90 midpoint). If AAPL closes below $225 at expiration, you keep the $190 and your shares. If AAPL closes above $225, your shares are called away at $225 — you still keep the $190 premium, but you miss any gain above $225. That is the core trade-off of every covered call, and the FINRA investor education library describes it clearly: the premium is yours regardless, but your upside is capped at the strike.

In VolRadar, you would open the AAPL options chain, scan the vol surface to confirm IV is elevated enough to make selling worthwhile, then manually scroll through strikes to find one near delta 0.25-0.30. You would calculate annualized yield yourself: ($1.90 ÷ $213.50) × (365 ÷ 30) = 10.8%. The math is not hard, but you are doing it strike by strike instead of sorting a pre-filtered list.

For a trader who owns five or ten different stocks and wants to review covered call opportunities across all of them in one session, the time difference adds up fast.

Where VolRadar Has a Real Edge

VolRadar's volatility analytics are genuinely stronger for traders who want to understand why IV is where it is before they sell. If you want to see whether NVDA's current implied volatility is in the top quartile of its two-year range, VolRadar gives you that picture quickly and cleanly. That context matters. Selling a covered call when IV is low means you collect less premium for the same amount of risk.

VolRadar also appeals to traders running multi-leg strategies — spreads, straddles, iron condors — alongside their covered calls. If you use covered calls as one tool among many, VolRadar's broader vol toolkit has value.

For pure covered-call income sellers who want a fast, filtered answer to the question 'which strike should I sell this week,' VolRadar asks you to do more work to get there.

Risks You Need to Know Before You Rely on Any Screener

No screener removes the risks built into covered calls. These risks exist regardless of which platform you use.

**Assignment risk.** If the stock closes above your strike at expiration, your shares are called away. The Options Industry Council (OIC) notes that early assignment — before expiration — is also possible on American-style options, especially around ex-dividend dates. A screener can show you the probability, but it cannot eliminate the outcome.

**Gap risk.** If the stock drops sharply — an earnings miss, a sector selloff, a macro shock — the premium you collected will not fully offset the loss in share value. Covered calls reduce your cost basis slightly; they do not protect you from a large downside move.

**Liquidity risk.** Wide bid-ask spreads mean your actual fill price may be worse than the midpoint. Always check open interest and volume before placing a trade. The SEC's Office of Investor Education and Advocacy has published guidance on how bid-ask spreads affect options trading costs.

**Tax treatment.** In the United States, the IRS treats covered call premiums as short-term capital gains in most cases. Selling a deep in-the-money call can also affect the holding period of your underlying shares under IRS qualified covered call rules. In Canada, the CRA has its own rules on how options premiums are taxed, and the treatment can differ depending on whether you are considered a trader or an investor. Consult a tax professional before making decisions based on screener output alone.

**Screener data lag.** Both platforms pull options data that may be delayed by 15 minutes or more on free tiers. Always verify the live quote in your brokerage before submitting an order.

Which Screener Should You Use?

If you are a retail investor who owns stocks and wants to sell covered calls to generate monthly income, Covered Call Pro's filters are more directly useful. The annualized yield sort, the delta ceiling filter, the earnings warning, and the spread-width flag all answer the exact questions you need to answer before placing a covered call trade.

If you are an active options trader who also sells covered calls but wants deep volatility analytics, term structure charts, and multi-strategy screening in one place, VolRadar adds value on top of a simpler covered-call workflow.

The two tools are not direct competitors in practice. Many serious covered-call sellers use Covered Call Pro to find and rank their setups, then glance at VolRadar to confirm the IV environment before pulling the trigger. That combination takes about five minutes per stock and gives you both the filtered shortlist and the vol context.

Bottom line: for covered-call-specific filtering, Covered Call Pro wins on speed, relevance, and ease of use. For raw volatility intelligence, VolRadar is the stronger tool. Know what you need before you pay for either.

Is VolRadar designed specifically for covered call sellers?

No. VolRadar is a broad volatility-analysis platform built for active options traders across multiple strategies. It shows implied volatility rank, term structure, and skew data that are useful for any options seller, but it does not have dedicated covered-call filters like annualized yield sorting or earnings-date warnings. Covered-call sellers can use it, but they will need to do more manual calculation to get to a trade decision.

What filters matter most when screening for covered calls?

The four most important filters are delta (to control assignment risk), annualized premium yield (to compare income across different strikes and expirations), days to expiration (most income sellers target 20-45 DTE), and bid-ask spread width (to protect your actual fill price). An earnings-date warning is also critical — selling a covered call through an earnings announcement adds significant gap risk that the premium rarely compensates for.

How do I calculate annualized yield on a covered call if my screener doesn't show it?

Divide the option premium by the current stock price, then multiply by 365 divided by the days to expiration. For example, a $1.90 premium on a $213.50 stock with 30 days to expiration equals ($1.90 ÷ $213.50) × (365 ÷ 30) = approximately 10.8% annualized. This lets you compare a 30-day trade to a 45-day trade on an apples-to-apples basis.

Can I get assigned early on a covered call?

Yes. American-style options — which cover most individual US stocks — can be exercised by the buyer at any time before expiration. The Options Industry Council (OIC) notes that early assignment is most common when a call is deep in the money or when the stock is about to pay a dividend. If your call is in the money heading into an ex-dividend date, the risk of early assignment rises meaningfully.

Are covered call premiums taxed as ordinary income in the US?

Generally, covered call premiums are treated as short-term capital gains under IRS rules, not ordinary income, though the distinction matters less since both are taxed at your marginal rate. However, the IRS has specific qualified covered call rules that can affect the holding period of your underlying shares, which matters if you are trying to qualify for long-term capital gains treatment on the stock. Always verify your situation with a qualified tax professional.

Does a higher implied volatility rank always mean I should sell a covered call?

Not automatically. A high IV rank means options premiums are elevated relative to the stock's historical range, which is generally favorable for sellers. But high IV often exists because the market expects a specific event — earnings, a product announcement, a legal ruling — that could cause a large price move. The premium may look attractive but may not compensate for the actual risk of a sharp gap down in the stock price.
