VolRadar vs Covered Call Pro: Which Screener Finds Better Covered Call Trades by Implied Volatility?

The Short Answer Before We Dig In

If you screen covered calls primarily by implied volatility rank (IVR) and want a workflow built around that single metric, Covered Call Pro is designed specifically for that job — it surfaces high-IVR opportunities on stocks you already own and lets you filter by delta, days-to-expiration, and premium yield in one pass. VolRadar is a broader options analytics platform that includes IV-based screening but targets active traders who also trade spreads, straddles, and directional plays. For a retail investor whose only goal is selling covered calls on a long stock portfolio, the two tools solve different problems, and knowing which one fits your situation saves you real money on subscription costs.

This article walks through how each platform handles IV screening, shows a worked example using AAPL, and lays out the honest trade-offs so you can make a clear-eyed choice.

Why Implied Volatility Is the Right Starting Point for Covered Calls

When you sell a covered call, you are selling time value — and time value is priced by implied volatility. The higher the IV on a stock's options, the more premium the market is paying for uncertainty. Selling calls when IV is elevated means you collect more income for the same strike and expiration than you would during a quiet market.

The metric most traders use is IV Rank (IVR), which measures where today's IV sits relative to the stock's own 52-week IV range. An IVR of 70 means IV is in the top 30% of its yearly range — a historically rich environment for selling. An IVR of 15 means you are selling cheap options and taking on capping risk without much reward.

The Options Industry Council (OIC) notes that understanding implied volatility is foundational to any options income strategy. FINRA also reminds retail investors that options involve risk and are not suitable for all investors — a point we will return to in the risk section. The core idea is simple: screen for high IVR first, then filter by strike and expiration. Both VolRadar and Covered Call Pro claim to do this, but they do it differently.

How Each Platform Handles IV Screening

Covered Call Pro is built around a covered-call-specific workflow. You input your existing stock positions — say, 200 shares of AAPL, 100 shares of MSFT, and 50 shares of NVDA — and the screener immediately shows you the current IVR for each position, ranks available strikes by annualized premium yield, and flags which expirations offer the best theta-per-day ratio. The dashboard is narrow by design. You are not looking at put spreads or iron condors. Every column on the screen is relevant to one trade type: the covered call.

VolRadar takes a wider-angle approach. Its IV screener scans the entire options universe and can surface high-IV stocks across all strategies. You can filter down to covered-call-relevant setups, but that filtering requires you to know what parameters to set. The platform gives you IV percentile, IV rank, historical volatility, and term-structure data — powerful inputs if you know how to use them. If you are a newer covered-call writer or you just want to quickly find the best call to sell on your AAPL position this Friday, that breadth can feel like noise.

In practical terms: Covered Call Pro answers the question 'Which call should I sell on the stocks I own today?' VolRadar answers the question 'Which stocks in the market have the most interesting volatility dynamics right now?' Both are legitimate questions. They are just different questions.

Worked Example: Screening AAPL for a Covered Call Using IV Rank

Let's make this concrete. Suppose AAPL is trading at $213.50 and its 30-day IV is 28%, while its 52-week IV range runs from 18% to 42%. That puts IVR at roughly 42 — meaning IV is sitting in the lower-middle of its annual range. Not ideal for selling, but workable.

In Covered Call Pro, you would see this IVR flagged in amber (moderate), and the screener would surface the nearest strikes above the current price. The $217.50 call expiring in 21 days might show a bid of $1.85, which works out to a 0.87% yield on the stock price for three weeks, or roughly 15% annualized. The $220 call at the same expiration might show $1.10 — a 0.52% yield, 9% annualized — with less cap risk but less income.

The screener also shows delta. The $217.50 call carries a delta of about 0.38, meaning there is a 38% probability (roughly) that AAPL closes above that strike at expiration and your shares get called away. The $220 call has a delta near 0.28. If you want to keep your shares with high probability, you lean toward lower delta. If you want maximum income and are comfortable selling at $217.50, you take the higher-premium strike.

In VolRadar, you would find the same AAPL data, but you would need to navigate to the covered-call-specific view, set your cost basis or current price manually, and cross-reference the IV rank data with the options chain yourself. The underlying numbers are the same — markets are markets — but the path to the answer is longer. For a trader managing five to fifteen stock positions and selling calls monthly, that extra friction adds up across a year.

What Are the Real Risks You Need to Know Before Using Either Tool?

No screener eliminates risk. Both platforms surface opportunities based on historical and current IV data, but IV can collapse or spike after you enter a trade. If you sell an AAPL $217.50 call and AAPL gaps up 8% on an earnings surprise, your shares get called away at $217.50 regardless of where the stock is trading. You keep the $1.85 premium, but you miss the upside above your strike. That is the core trade-off of covered calls: capped upside in exchange for income.

FINRA's investor education materials are explicit that covered calls limit your profit potential and do not fully protect against a decline in the underlying stock. If AAPL drops from $213.50 to $195, your $1.85 premium offsets only a small portion of that loss. The screener did not cause that loss, but a screener that only shows you premium yield without showing you downside exposure is giving you an incomplete picture. Covered Call Pro displays the breakeven price on every trade. Make sure any tool you use does the same.

On the tax side, the IRS treats premiums received from selling covered calls as short-term capital gains in most cases, and the timing of when you close or let a call expire affects your cost basis on the underlying shares. In Canada, the CRA has its own rules on option premiums and adjusted cost base. Neither VolRadar nor Covered Call Pro provides tax advice — consult a qualified tax professional before making decisions based on after-tax yield estimates from any screener.

Finally, both platforms rely on real-time or near-real-time options data. Bid-ask spreads on less liquid options can be wide, and the 'mid-price' yield a screener shows you may not be the fill you actually get. Always check the actual bid before placing an order, especially on stocks outside the top 100 by options volume.

Pricing, Data Quality, and Who Each Tool Is Really Built For

Pricing structures change, so check each platform's current pricing page directly. As of this writing, VolRadar positions itself as a professional-grade tool with pricing that reflects its broader feature set. Covered Call Pro is priced for the retail covered-call writer who does not need spread analytics or volatility surface modeling.

Data quality on both platforms draws from standard options data feeds. The difference is in how that data is processed and presented. VolRadar gives you raw analytical power. Covered Call Pro gives you a filtered, covered-call-specific output. Neither platform is 'better' in an absolute sense — the better tool is the one that matches how you actually trade.

If you own a portfolio of 8 to 20 stocks and sell covered calls monthly for income, Covered Call Pro's focused workflow will save you time and reduce the chance of screening errors. If you are an experienced trader who also runs volatility strategies beyond covered calls and wants one platform for everything, VolRadar's depth may justify its cost. Many serious covered-call traders use a dedicated covered-call screener for their income trades and a broader platform for research — that is a reasonable approach if the combined cost fits your budget.

A Side-by-Side Summary of the Key Differences

Here is a plain comparison across the dimensions that matter most to covered-call writers:

Primary use case: Covered Call Pro is built exclusively for covered-call screening. VolRadar covers the full options strategy spectrum.

IV rank display: Both show IVR. Covered Call Pro surfaces it as the primary sort metric for your existing holdings. VolRadar shows it as one of many data points in a broader scan.

Portfolio integration: Covered Call Pro lets you input your current positions and screens only those tickers. VolRadar scans the market broadly; portfolio-specific filtering requires manual setup.

Strike and expiration filtering: Covered Call Pro pre-filters to covered-call-relevant strikes and expirations. VolRadar shows the full options chain with all strategies.

Learning curve: Covered Call Pro is accessible to investors who are new to options screening. VolRadar rewards users who already understand volatility analytics.

Risk display: Covered Call Pro shows breakeven price and cap risk on each trade. VolRadar provides the data to calculate these yourself.

Bottom line: if your question is 'which call do I sell on my AAPL position this week given current IV,' Covered Call Pro answers that question faster and with less room for error. If your question is 'what is the volatility environment across the market and how do I position across multiple strategies,' VolRadar is the stronger tool.

Does VolRadar show IV rank for covered call screening?

Yes, VolRadar displays IV rank and IV percentile as part of its options analytics suite. However, it is designed for traders running multiple strategies, so you will need to filter the data yourself to isolate covered-call-relevant setups. Covered Call Pro surfaces IV rank specifically in the context of your existing stock positions and covered-call strike selection.

What IV rank is considered good for selling covered calls?

Most covered-call writers look for an IVR of 50 or higher before selling, meaning IV is in the top half of its 52-week range. An IVR above 70 is generally considered a rich environment for selling premium. Below 30, you are selling cheap options and may not be compensated well for the cap risk you are taking on.

Can I use these screeners if I am a Canadian investor?

Both platforms are accessible to Canadian investors trading US-listed options. Keep in mind that the CRA treats option premiums differently than the IRS does, so the after-tax yield on a covered call will differ depending on your account type and residency. Consult a Canadian tax professional familiar with CRA rules on options income before making decisions based on screener yield estimates.

Is selling covered calls based on IV rank a reliable income strategy?

Selling covered calls in high-IV environments has historically produced better premium income than selling in low-IV environments, because you collect more premium for the same strike and expiration. However, high IV often signals that the market expects a large move, which means your shares are more likely to be called away or to drop significantly. FINRA notes that covered calls do not protect against downside losses in the underlying stock.

How do I know which strike to sell after I find a high-IV stock?

Start with delta as your guide: a delta of 0.20 to 0.35 on the call you sell means roughly a 20% to 35% probability of the stock closing above that strike at expiration. Lower delta means you keep your shares more often but collect less premium. Higher delta means more income but a greater chance your shares get called away. Covered Call Pro displays delta alongside premium yield so you can balance the two directly.

Do I need Level 2 options approval to sell covered calls?

In the US, selling covered calls typically requires Level 1 or Level 2 options approval depending on your broker, since the position is considered relatively low risk — you already own the underlying shares. The SEC and FINRA require brokers to assess your options knowledge and financial situation before granting approval. Contact your broker directly to confirm your current approval level before placing a covered-call trade.
