Understanding Calendar Spreads

At its core, a calendar spread involves taking long and short positions on the same asset but with different delivery dates. Often referred to as ‘time spreads’ or ‘horizontal spreads,’ these strategies involve simultaneously holding two positions with the same underlying asset but different expiration dates. A calendar spread’s appeal lies in its simplicity and potential to profit from time decay and volatility changes.
Typically, traders maintain the same strike price for both options in a calendar spread to ensure it remains a pure extrinsic value trade. The primary goal is to profit from the passage of time or an increase in implied volatility. The strategy aims to capture opportunities arising from market conditions, such as volatility, time decay, and delayed price movement.
Calendar spreads are particularly effective in range-bound markets, where they can generate profits even if the market moves sideways, depending on the setup. Whether you’re using call or put options, understanding the factors that determine the optimal time frame for a calendar spread—such as market conditions, underlying asset, and volatility expectations—is crucial.
Types of Calendar Spreads

Calendar spreads come in various forms, each with its unique characteristics and applications. The main types of calendar spreads are long and short calendar spreads, and they can be further divided based on whether they use call or put options. A calendar spread long is one of the strategies traders may consider.
Long Call Calendar Spread
A long call calendar spread consists of two components. It involves purchasing a long call option with a later expiration while simultaneously selling a short call option that has a closer expiration. This calendar spread involves two options. It includes selling a short call and purchasing a long call at the same strike price, but they have different expiration dates. Designed to capitalize on time decay in a low-volatility environment, this strategy carries limited risk and aims to have the short option expire out-of-the-money while profiting from the long option.
The maximum risk for this strategy is the debit paid, which is calculated by subtracting the premium received from the short call from the cost of the long call. If the stock price rises after the short-term option expires but before the longer-term option ends, it can also benefit the long call calendar spread.
Theoretically, the maximum reward is unlimited, making it an attractive option for traders anticipating a stable or slightly bullish market in the near term.
Long Put Calendar Spread
A long put calendar spread involves buying a longer-term put option and selling a shorter-term put option at the same strike price. This strategy can be particularly beneficial when stock prices fall and volatility increases between expirations. The net cost for setting up a long put calendar spread is typically a debit, as the trader pays more for the longer-term put than they receive for the shorter-term put.
For example, with a strike price of $40, if the stock price falls to $42 after five weeks, the trader can sell another put, exit the long put for a profit, or wait longer. If the short put expires worthless, the long put can still hold value, providing potential profit opportunities related to strike prices.
This strategy is often used when traders expect the stock price to stay steady or rise slightly in the near term.
Short Call Calendar Spread
A short call calendar spread involves selling a call option with a longer expiration date while buying a call option with a shorter expiration date at the same strike price. This strategy profits from a stable underlying price or a decline in volatility. The maximum profit can be realized if the longer-term short option expires out-of-the-money, allowing the trader to keep the premium collected.
A short call calendar spread succeeds if the stock price remains at or below the short call’s strike price before expiration and then rises beyond the long call with increased volatility. If the underlying stock price decreases, the position can be adjusted to a lower level. Alternatively, it can also be maintained as is.
However, this strategy carries greater risk if the underlying asset moves sharply against the position.
Short Put Calendar Spread
A short put calendar spread consists of buying a put option with a shorter expiration date. At the same strike price, you sell a put option that has a longer expiration date. The premium received for initiating this strategy provides some cushion, but the maximum loss can be substantial if the stock price falls significantly.
Traders typically use this strategy when expecting the stock’s price to remain stable or slightly increase. If the stock price moves significantly against the position, the trader may face higher losses.
Proper risk management and monitoring are essential to mitigate potential downsides.
Setting Up Your Calendar Spread
To set up a calendar spread, traders sell a near-term option and buy a longer-term option at the same strike price. The initial cost of establishing a call calendar spread, known as the debit paid, defines the trade’s maximum risk. For the call calendar spread to be successful after the first expiration, the stock price must be below the options’ strike price.
Many traders underestimate the importance of timing the sale of near-term options, which can lead to unfavorable outcomes. Additionally, transaction costs can significantly impact the profitability of calendar spreads, making it essential to factor them into your strategy.
For European-style options, the maximum loss is limited to the initial premium paid. This makes the long calendar spread a relatively low-risk strategy, as the maximum loss is confined to the initial cost associated with establishing the trade.
Profit Potential and Risks

The profit potential of calendar spreads depends on various factors, including the underlying asset’s price remaining close to the strike price. Successful calendar spreads rely on the short option expiring out-of-the-money, leaving the trader with a long position that has unlimited profit potential. However, gains in a long calendar spread are limited and may be offset by losses from the short option.
Higher implied volatility can enhance the value of calendar spreads, particularly benefiting the long call option. Conversely, decreasing volatility can hurt calendar spreads, as both options may lose value, especially the long-term option. The net premium collected is the maximum reward for a short calendar spread, but this strategy carries greater risk if the underlying asset moves sharply against the position.
Timing plays a critical role in the success of calendar spreads. Waiting too long for profit can lead to detrimental price movements, and the calendar spread’s performance can be adversely affected in environments of decreasing volatility. Effective risk management and understanding the impact of time decay and volatility are essential for maximizing profit and minimizing loss.
Managing Calendar Spreads

Managing calendar spreads effectively is key to maximizing profit or minimizing loss. A common strategy involves closing positions to secure profits when the trade reaches 10% to 25% of the premium paid. Monitoring market conditions continuously is essential to maintain effective management of your calendar spread positions.
Adjustments can be made to calendar spreads to mitigate risks. Rolling short options out in time can provide credits, reducing the maximum risk of the position. Rolling the short option up can help manage risks when the underlying stock price increases. Exiting one to two weeks before the short strike’s expiration is often a strategic time for traders to make adjustments.
Time Decay and Implied Volatility
Time decay, which reduces the value of options as they near expiration, is critical in calendar spreads. Short-term options lose value quickly, while long-term options lose value more slowly. The maximum time decay for short-term options occurs in the final weeks before expiration, making this period crucial for managing calendar spreads.
Implied volatility also plays a significant role in the profitability of calendar spreads. An increase in implied volatility generally enhances the value of calendar spreads, particularly benefiting the long call option. However, many traders neglect to account for the impact of implied volatility changes, which can significantly affect the profitability of calendar spreads.
Example Trades
Let’s consider an example to illustrate how calendar spreads work in practice. Suppose you set up a calendar spread with the same strike price by buying a long call option with a later expiration and selling a short call option with a closer expiration. The net cost of this calendar spread is $1.25 or $125 for one spread.
The ideal price for the underlying asset at the near-term expiration to profit from this calendar spread is just below $95. After the near-term option expires, the payoff diagram resembles a long call, offering unlimited profit potential.
This example shows how calendar spreads can effectively capitalize on time decay and volatility.
Advanced Strategies: Double Calendar Spreads

Traders exploring advanced strategies might find the double calendar spread intriguing. A double calendar spread consists of two calendar spreads using both call and put options at the same strike price but with different expiration dates. This strategy allows for a wider breakeven range compared to a standard calendar spread.
In a double calendar spread, the trader sells both calls and puts of near-term options and purchases calls and puts of longer-term options. This approach can provide greater flexibility and potential profit opportunities, making it a valuable addition to any trader’s toolkit.
Common Mistakes to Avoid
Traders should be cautious of early assignment risk for short-term options, which can lead to unexpected losses. Misjudging market volatility can result in poor option selection and timing for calendar spreads. A clear exit strategy is crucial; failing to have one can lead to indecision and missed opportunities during trades.
Another common mistake is not adjusting positions in response to market movements, leading to missed opportunities or increased losses. Failing to monitor the delta of the options can result in unexpected exposure to price movements of the underlying asset. Avoiding these pitfalls can lead to more consistent and profitable trades.

Using the right tools and resources is essential for successfully trading calendar spreads. Tools like Autospreader allow traders to create synthetic spreads across various exchanges. Colocated execution on Linux servers can help traders achieve rapid quoting and hedging for their calendar spread trades.
