ThetaGo Alternatives for Buy-and-Hold Covered Call Screening: What Actually Works

The Short Answer: Yes, There Are Better Fits Depending on Your Style

If you own stocks long-term and sell covered calls on top of them, ThetaGo is one option — but it is not the only one, and for many buy-and-hold investors it is not the best fit. Tools like Barchart Options Screener, CBOE's free resources, your broker's built-in screener (think Thinkorswim or Fidelity's options chain), and dedicated platforms like OptionStrat or PowerOptions each solve a different piece of the puzzle. The right choice depends on how many positions you manage, whether you want automation, and how much you want to pay.

This article walks through the main alternatives, shows you a real worked example on AAPL, and flags the risks and tax wrinkles you need to know before you switch tools.

What Buy-and-Hold Covered Call Traders Actually Need From a Screener

A covered call screener for a buy-and-hold investor has a different job than one built for active options traders. You are not hunting for the highest premium regardless of the stock. You already own the stock — or you are willing to own it long-term — and you want to find the strike and expiration that earns you the most income without forcing you to sell shares you want to keep.

That means the screener needs to show you at minimum: annualized return on the call premium, the probability the option expires worthless (often shown as 1 minus delta, or directly as probability OTM), the bid-ask spread (a wide spread kills your real-world return), and whether the stock has an upcoming earnings date inside your expiration window. Earnings inside the window spike implied volatility and can cause the stock to gap past your strike, triggering an unwanted assignment.

ThetaGo surfaces some of these filters, but its interface is built around scanning the whole market for high-yield calls. If you already hold AAPL, MSFT, and a handful of other names, you do not need a market-wide scan — you need a fast, clean way to evaluate one or two strikes on stocks you already own. That is where several alternatives pull ahead.

The Main Alternatives: A Plain-English Comparison

**Barchart Options Screener (free and paid tiers):** Barchart lets you filter by underlying, expiration range, moneyness, implied volatility rank, and annualized premium yield. The free tier gives you enough data for a small portfolio of five to ten positions. The paid tier adds real-time quotes and more filter combinations. For a buy-and-hold investor managing a concentrated stock portfolio, this is often the first upgrade from a basic broker chain.

**Thinkorswim (TD Ameritrade / Schwab, free with account):** The built-in options chain on Thinkorswim shows delta, theta, probability OTM, and bid-ask spread in one view. You can set up a custom watchlist of your holdings and scan strikes across expirations in seconds. Because it is broker-integrated, you can go from screening to placing the trade without switching windows. FINRA requires brokers to approve you for options trading before you can trade, but the screening tools are available to any account holder.

**Fidelity Active Trader Pro (free with account):** Similar to Thinkorswim for basic covered call work. The options chain is clean, probability data is built in, and Fidelity's tax reporting integrates directly — relevant because the IRS treats covered call premiums as short-term capital gains in most cases, and having everything in one place simplifies your Schedule D.

**OptionStrat (free and paid):** OptionStrat is strong on visualizing the payoff diagram and break-even at expiration. It is less of a screener and more of a trade analyzer. If you have already identified a strike and want to stress-test it — what happens if AAPL drops 8% before expiration? — OptionStrat answers that question clearly. It is a good complement to a screener, not a replacement.

**PowerOptions (paid subscription):** PowerOptions is one of the oldest dedicated covered call screening platforms. It lets you filter by annualized return, downside protection, days to expiration, and whether the stock pays a dividend. For investors managing 15 or more covered call positions, the time savings can justify the subscription cost. It also flags ex-dividend dates, which matters because early assignment risk rises when a call is deep in the money near an ex-dividend date — a point the Options Industry Council (OIC) covers in detail in its covered call educational materials.

**CBOE's Free Tools:** The CBOE website offers a BuyWrite index (CBXM) and educational calculators. These are not screeners in the practical sense, but they give you benchmark data on what a systematic covered call strategy on the S&P 500 has historically returned. Useful for setting realistic expectations before you pick any tool.

Worked Example: Screening a Covered Call on AAPL

Let's say you own 100 shares of Apple (AAPL) purchased at $170. The stock is currently trading at $213. You want to sell a covered call expiring in about 30 days and you do not want to sell your shares — so you need a strike above $213 that still pays a meaningful premium.

Using Barchart or Thinkorswim, you pull up the AAPL options chain for the expiration roughly 30 days out. Here is what a realistic snapshot might look like (prices are illustrative based on typical AAPL volatility):

- **$215 strike (just OTM):** Bid $3.10, ask $3.20. Delta ~0.45. Probability OTM ~55%. Annualized yield on premium: roughly 17% on the current stock price. High premium, but a 55% chance of assignment means you have nearly a coin-flip shot of being forced to sell at $215.

- **$220 strike:** Bid $1.60, ask $1.70. Delta ~0.28. Probability OTM ~72%. Annualized yield: roughly 9%. You keep the shares about 72% of the time, and you still collect $160 per contract (using the $1.60 bid).

- **$225 strike:** Bid $0.75, ask $0.85. Delta ~0.15. Probability OTM ~85%. Annualized yield: roughly 4%. Very low assignment risk, but the income is thin.

For a buy-and-hold investor who does not want to sell AAPL, the $220 strike is the classic sweet spot: meaningful income, reasonable protection of the position. The screener's job is to surface that $220 row quickly, show you the bid-ask spread is tight (good liquidity), and confirm there is no earnings announcement before expiration. All three of the tools above — Barchart, Thinkorswim, and Fidelity — do this well. ThetaGo would also show you this, but it takes more clicks to get there if you are starting from your existing holdings rather than a market-wide scan.

Risks You Need to Know Before You Switch Tools (or Start Screening)

Switching screeners does not change the underlying risks of covered calls. A better tool helps you find trades faster — it does not make bad trades good.

**Assignment risk:** If AAPL closes above your $220 strike at expiration, your 100 shares get called away. You keep the $160 premium, but you lose the upside above $220. If you have a large unrealized gain in those shares (say, you bought at $100), assignment triggers a taxable event. The IRS taxes the gain on the shares as a capital gain — long-term if you held more than a year, short-term if less. The premium itself is generally treated as short-term capital gain income regardless of how long you held the stock. Consult a tax professional; the IRS Publication 550 covers options taxation in detail.

**Canadian investors — CRA rules differ:** The Canada Revenue Agency (CRA) treats covered call premiums as capital gains or income depending on your trading frequency and intent. Buy-and-hold investors writing occasional calls are more likely to get capital gains treatment, but the CRA looks at the full picture. Check CRA Interpretation Bulletin IT-479R for guidance.

**Capping your upside:** This is the most common regret for buy-and-hold investors. If you sell the $220 call and AAPL runs to $240 before expiration, you miss $20 per share of gains. No screener eliminates this trade-off. It is the fundamental cost of collecting premium.

**Bid-ask spread drag:** A screener that shows you gross premium without flagging wide spreads is misleading. Always use the bid price, not the midpoint, as your realistic fill estimate on a liquid name. On illiquid stocks, the spread can eat 20-30% of the quoted premium.

**Early assignment:** American-style options (all standard US equity options) can be assigned early. This is rare but happens most often when a call is deep in the money close to an ex-dividend date. The OIC notes this in its covered call module and recommends monitoring ex-dividend dates actively.

Which Tool Should You Actually Use?

Here is a simple decision framework:

- **You manage 1-5 positions and want to spend nothing:** Use your broker's built-in chain (Thinkorswim, Fidelity, or Schwab). It is free, integrated, and good enough for a small portfolio.

- **You want a dedicated screener with more filters and you manage 5-15 positions:** Start with Barchart's free tier. Upgrade to paid if you find yourself hitting the data limits regularly.

- **You manage 15+ covered call positions and your time is worth money:** PowerOptions or a similar paid platform pays for itself in time saved. Run the numbers: if the subscription saves you two hours a month and your time is worth $50 an hour, a $30/month subscription is a clear win.

- **You want to stress-test a specific trade before placing it:** Add OptionStrat as a free companion to whatever screener you use.

- **You want market-wide scanning to find new stocks to buy and write calls on:** This is where ThetaGo and similar tools shine. But if you are a buy-and-hold investor who already owns your stocks, this feature is largely irrelevant to your workflow.

The bottom line: ThetaGo is a reasonable tool, but it is optimized for a different use case than most buy-and-hold covered call writers. Your broker's free screener plus Barchart covers 90% of what you need at zero additional cost. Only pay for a dedicated platform when your portfolio size makes the time savings real.

Is ThetaGo free to use for covered call screening?

ThetaGo offers a free tier with limited scans and a paid subscription for full access. For buy-and-hold investors who only need to evaluate calls on stocks they already own, the free tiers of Barchart or a broker-integrated tool like Thinkorswim often provide comparable data at no cost. Always compare what data each tier actually shows before paying for a subscription.

What is the most important number to look at when screening a covered call?

Annualized return on the premium and probability the option expires worthless (probability OTM) are the two numbers that matter most for buy-and-hold investors. A high annualized return with a low probability OTM means you are likely to be assigned and lose your shares, which defeats the purpose of a buy-and-hold strategy. The Options Industry Council (OIC) recommends balancing income against assignment risk when selecting strikes.

How do I avoid selling a covered call right before an earnings announcement?

Any quality screener — including Barchart, Thinkorswim, and PowerOptions — will show you the next earnings date for the underlying stock. Always confirm the earnings date falls outside your expiration window before selling the call. Earnings announcements inside the window inflate implied volatility and dramatically increase the chance of a large price move that blows through your strike.

Are covered call premiums taxed as ordinary income or capital gains?

In the US, covered call premiums are generally treated as short-term capital gains, reported on Schedule D, regardless of how long you have held the underlying stock — see IRS Publication 550 for details. In Canada, the CRA may treat premiums as capital gains or income depending on your trading frequency and intent; CRA Interpretation Bulletin IT-479R provides guidance. Always consult a qualified tax professional for your specific situation.

Can I use a free broker screener instead of paying for a dedicated covered call tool?

Yes, for most buy-and-hold investors managing fewer than 10 positions, a broker-integrated screener like Thinkorswim (Schwab) or Fidelity Active Trader Pro provides all the data you need — delta, probability OTM, bid-ask spread, and expiration dates — at no extra cost. Paid tools like PowerOptions add value mainly when you are managing a larger number of positions and the time savings justify the subscription fee.

What happens if my covered call gets assigned early?

Early assignment on a covered call means your shares are purchased by the option buyer before expiration, which can happen with American-style options when a call is deep in the money near an ex-dividend date. You keep the premium you collected, and your shares are sold at the strike price, triggering a capital gain or loss on the stock position. The OIC covers early assignment risk in its covered call educational materials and recommends monitoring ex-dividend dates closely.
