COVERED CALLS - THE CAP DRAWN, NOT CROPPED
Covered call backtest: test a covered call strategy or a wheel strategy
Type the income structure the way you would say it out loud, such as "sell 30-delta covered calls on SPY, rolled monthly", and the bench tests it on 20+ years of split- and dividend-adjusted history with every assumption printed, then compares it against simply holding the shares.

In short
A covered call backtest applies a call-writing rule to historical data so you can see how the income structure actually behaved: how much premium it added, how much upside the cap took away, and whether the combination beat just holding the stock. In Agenttrading you describe the rule in plain English, such as "sell monthly 30-delta covered calls on SPY and roll at expiration" or "run the wheel on QQQ: cash-secured puts until assigned, then covered calls until called away", confirm the restated structure, and the test runs on 20+ years of split- and dividend-adjusted daily history with the assumptions strip printed on every result: strike selection, roll schedule, assignment handling, and the 0.1% cost per trade assumed by default. The verdict is honest about the shape of these trades. Call writing historically smooths returns and caps upside, so in long bull stretches a covered call rule frequently trails buy-and-hold on total return while cutting the size of the swings, and the chart draws the capped stretches instead of cropping them. What this is not: a chain-level options analytics vendor. If you need historical bid and ask quotes for every strike and expiry, an options data specialist such as ORATS or MarketChameleon is the right tool. Here the point is the shape of the trade-off and the honest comparison against holding the shares, with the modeling assumptions on screen rather than buried. Covered call backtesting is included on the Analyst plan at $49 per month. No trades are executed, nothing is recommended, and the output is educational analysis only: past performance does not guarantee future results, especially in options.

WHAT YOU GET - COVERED CALL BACKTEST
Covered call backtest, run on the bench
The cap is on the chart
Selling calls trades upside for premium. The backtest draws every stretch where the stock ran past your strike and the position got called away, instead of quietly cropping the chart at the good part.
Assumptions printed, always
Strike selection, roll schedule, how assignment is handled, the date range, and the 0.1% default cost per trade appear on every result. Options results live or die on assumptions, so they belong on screen.
Wheel and poor man's covered call in a sentence
The wheel (cash-secured puts until assigned, then covered calls until called away) and a poor man's covered call using a long-dated call in place of shares are typed the way you would say them. No options-chain spreadsheet, no scripting.
Benchmarked against just holding the shares
The only comparison that matters for call writing is buy-and-hold on the same ticker over the same window. HELD UP, MIXED, and UNDERPERFORMED are stamped honestly, because a covered call test that cannot disappoint you is not evidence.
HOW IT WORKS - 4 STEPS
From a sentence to a stamped verdict
Describe the call-writing rule
One sentence with the parameters you care about: the ticker, how far out of the money or which delta, days to expiration, and how often you roll.
Confirm the restated structure
Strike logic, roll schedule, assignment handling, and position sizing are shown as an explicit card before anything runs. Adjust until it matches what you meant.
Run it across 20+ years
The structure tests on split- and dividend-adjusted daily history with costs charged per trade, plotted against holding the shares, with the worst drawdown window shaded.
Read the trade-off and the verdict
Where premium helped, where the cap cost you, how deep the drawdown still went, and whether the sample is large enough to mean anything. In plain English, never as a recommendation.

On the same bench
Covered calls are one structure among several on options backtesting, which also covers cash-secured puts and vertical spreads, and every rule is typed in the same place as anything else in the trading strategy builder. The adjusted 20-year record behind each run is described on historical stock data, and the drawdown a call-writing program would still have handed you is explained on investment risk analysis. Income investors comparing call writing against plain dividend income should read dividend backtesting. For the full method, read how to backtest a covered call strategy; plans start at $19 per month.
QUESTIONS - ASKED AND ANSWERED
Covered call backtest: the common questions
How do you backtest a covered call strategy?
Define the underlying, the strike rule (a delta or a percentage out of the money), the days to expiration, the roll schedule, and what happens on assignment, then run it on long adjusted history with a realistic cost per trade and compare it against holding the shares. In Agenttrading you type that rule as a sentence, confirm the restated structure, and read the result with the assumptions printed on it.
Can you backtest covered calls?
Yes. Agenttrading tests a call-writing rule such as "sell 30-delta covered calls on SPY, rolled monthly" on 20+ years of split- and dividend-adjusted history, with strike selection, roll schedule, assignment handling, and the 0.1% default cost per trade printed on the result. It ships with the Analyst plan at $49 per month. Nothing is executed and nothing is recommended.
Do covered calls outperform buy and hold?
Usually not on total return over long horizons, and that is the structural reason: the premium is capped income while the downside is only cushioned, not removed. Call writing historically produced smoother returns with shallower swings and gave up the biggest up months, so it tends to trail buy-and-hold in strong bull markets and hold up better in flat or choppy ones. A backtest on your own ticker settles which case you are in.
How far out of the money should covered calls be?
There is no single right distance, which is exactly why it is worth testing rather than guessing. A closer strike collects more premium and gets called away more often; a further strike keeps more upside and collects less. Because volatility changes, a fixed percentage like 10% out of the money means something different in a calm market than in a violent one, which is why delta-based rules are more stable. Test two or three variants on the same window and read the spread.
How do you backtest the wheel strategy?
State the full cycle as one rule: sell cash-secured puts on the ticker at a given delta, take assignment if it finishes in the money, then sell covered calls on the assigned shares until they are called away, and repeat. The parts that decide the answer are the strike distance on both legs, the cash reserved against the puts, and what happens in a sustained decline, when the wheel leaves you holding a falling stock. Run it against holding the shares over the same period.
What is a poor man's covered call and can you backtest one?
A poor man's covered call replaces the 100 shares with a long-dated in-the-money call, so a short call is written against an option instead of stock. It costs far less capital and adds two risks the standard version does not have: the long leg has an expiration date and it loses time value. You can describe the structure in plain English here and test it, and the result should be read next to a plain covered call on the same ticker rather than in isolation.
Do covered call backtests account for assignment and early exercise?
They have to, and Agenttrading states its handling on the result rather than hiding it. Assignment is what turns a covered call program into a series of realized gains and forced exits, and early exercise around ex-dividend dates changes the outcome for dividend payers. A test that silently assumes you always keep the shares overstates the strategy, so the assumption is printed with every run.
Is a covered call backtest accurate?
It shows what a rule would have done in history under stated assumptions, not what it will do, and options add extra sensitivity to those assumptions. Strike selection, implied volatility at the time of sale, and slippage all move the result, so Agenttrading prints the assumptions strip and flags thin samples. If you need per-strike historical quotes, use a chain-level options data vendor. Past performance does not guarantee future results, especially in options.
