Common Variations
The default setup above is one version of the call calendar spread. Traders adjust strike placement to trade off cost, probability, and payout:
OTM call calendar
Use a strike above the current stock price instead of at-the-money.
Key difference: Adds a mild bullish lean — the trade benefits from a moderate rally into the strike by expiration of the front-month leg.
Best for: Traders who want time-decay income with a directional tilt.
Double calendar
Run a call calendar at one strike and a put calendar at another simultaneously.
Key difference: Widens the profitable range across two strikes rather than concentrating it at one.
Best for: Traders who want calendar-style income without pinpointing a single exact price.
Frequently Asked Questions
Why sell a near-term option and buy a longer-dated one at the same strike?
Setup
The near-term option decays faster (time decay accelerates as expiration nears), so selling it and buying a slower-decaying longer-dated option captures that decay differential as profit if the stock stays near the strike.
What's the ideal outcome for a call calendar spread?
When to Use
The stock sits near the strike as the front-month option expires worthless, after which the back-month long call retains most of its value and can be sold or held.
Is this a bullish or neutral strategy?
Comparisons
At the same strike as the current price it's essentially neutral, profiting mainly from time decay and rising implied volatility on the back-month leg rather than direction.
What happens after the front-month option expires?
Adjustments
You're left holding the long back-month call outright, which can be closed for a profit, held as a standalone directional position, or turned into a new calendar by selling another near-term option against it.
