To do this, they can sell a short call option and simultaneously buy a long call option with a higher strike price. Thus, the trader can switch from the calendar spread to a more secure position in the form of a call option with a higher strike price. What is certain is that the trade will make maximum profit when it closes at either of the two peaks, that is, at the strike prices where the calendar spreads have been created. Calendar spreads are usually lower probability trades, but they can be very effective and profitable trading strategies, particularly when implied volatility is low.
Call calendar spreads can be adjusted during the trade to increase credit. If the underlying stock price declines rapidly before the first expiration date, the short call option can be purchased and sold at a lower strike closer to the stock price to receive additional credit. The long put contract will have a higher premium because it has more extrinsic time value, so you will likely pay a debit to enter the trade.

To open a call calendar spread, sell-to-open (STO) a short call option and buy-to-open (BTO) a long call option at the same strike price but with a later expiration date. The position can be adjusted lower if the underlying stock price drops. A put calendar spread is a risk-defined options strategy with unlimited profit potential. Put calendar spreads are neutral to bullish short-term and slightly bearish long-term. To open a put calendar spread, sell-to-open (STO) a short put option and buy-to-open (BTO) a long put option at the same strike price but with a later expiration date. The long call contract will have a higher premium because it has more extrinsic time value, so you will likely pay a debit to enter the trade.
Legging out of a call calendar spread can increase the risk beyond the initial debit paid, but creates the highest profit potential. The decision to exit a call calendar spread will depend on the underlying asset’s price at the expiration of the short call contract. If the stock price is below the short call, the option will expire worthless. The long call option will be out-of-the-money and have time value remaining. The extrinsic time value will depend on the length of time until expiration and the strike price relative to the stock price. If you choose to only close the in-the-money short put option, there is potential for more risk.

A calendar spread is executed with the same type of option ― either a call or a put on both legs of the spread. These profit from a difference in the rate of time decay between the short-term option (fast) and the longer-term option (slower). When they are done using the at-the-money strike price as in our example, they are neutral with respect to the price of the underlying. If a higher strike price is used, they are bullish, and with a lower strike, they are bearish. Making adjustments are one way to manage risk when a trade starts to go bad.

If the underlying stock price is above the short call at the first expiration date, both options may be closed to exit the position. A call calendar spread is purchased when an investor believes the stock price will be neutral or slightly bearish short-term. The position would then benefit from an increase in price and volatility after the short-term contract expires and before the longer-dated contract is closed. If the underlying stock price is above the short call at expiration, the long call may be exercised to cancel out the assignment of the short shares. Generally, put calendar spreads benefit from an increase in implied volatility.

- If the stock price is above the short put strike at expiration–which is the goal of the calendar spread–the short contract will expire worthless.
If the stock price is above the short put strike at expiration–which is the goal of the calendar spread–the short contract will expire worthless.

A put calendar spread consists of selling-to-open (STO) a short put option and buying-to-open (BTO) a long put option at the same strike price but with a later expiration date. At the near-term expiration, the payoff diagram slightly resembles an inverted V. After the near-term expiration, if the long put option is held, the payoff diagram is the same as a long put. If the stock price falls and/or implied volatility increases before the long put’s expiration date, the position will gain value. If the stock price rises, the extrinsic value of the long put will decrease. The payoff diagram for a put calendar spread is variable and has many different outcomes depending on when the options trader decides to exit the position. The maximum risk is defined at entry by the debit paid to enter the spread if both options are exited at the first expiration.
If the implied volatility of the longer-term option is higher than that of a shorter-term option, the strategy will be profitable. By contrast, if the implied volatility of the options is comparable, the strategy’s profitability may be limited. The rate of decay of the near-term option increases with time and will increase as we close on the near options expiry. Also, assuming all things remain unchanged, the passage of time would have a positive calendar spread adjustments impact on the strategy till the expiry of the near-term option expiry.

The price of the asset most optimal for the maximization of the strategy profit is called the sweet spot. In terms of a calendar spread, this point is reached when the short option is executed “in the money” or slightly “out of the money”. In this case, the short option has zero value (which is an advantage for an option seller), and the long option still has a time value. On the date of expiry, the maximum gain would occur when the price of the underlying asset closes at or below the strike price of the near-term expiry, which would be worthless. If volatility is high on the day of expiry, the far-term option will add to the profitability. The maximum profit of a calendar spread is the net credit received by the trader from the sale of a short-term option.
