Any options trader have heard of a diagonal spread, one of the effective options trading strategies. This article unfolds the related basics, such as what it is, how to adapt it, and the correlation between spread and volatility. Scroll down to this blog for more information!

What Is a Diagonal Spread?

A diagonal spread refers to an adjusted version of a calendar spread with different strike prices. The setup includes the entry of a long and short position in two options of the same type at different strike prices and expiry dates. It is applicable in both bullish and bearish markets.

How Does a Diagonal Spread Work?

The combination between a horizontal spread (time spread) and a vertical spread (price spread) makes an option diagonal spread. It refers to the positions of options on an options grid at different strike prices and expiration dates.

A horizontal spread involves a difference in expiration dates and the same strike prices. Meanwhile, a vertical spread indicates different strike prices and the same expiration dates.

Types of Diagonal Spreads

Each option includes two elements, including strike price and expiration date. These factors also create different types of diagonal spreads, such as bullish, bearish, long, short, call options, or put options.

Most diagonal spreads are long spreads as long as the holder purchases the option with the extended expiration date and sells it with less maturity time.

On the other hand, short spreads ask for a shorter expiration for purchase and a longer expiry duration for sale. This requirement is alike for both call diagonal spread and put diagonal spread.

A Beginner’s Guide on Closing a Diagonal Spread

How to Close a Trade With a Diagonal Spread

When you collect enough premium from the trade, you would like to close a diagonal spread. Otherwise, you will close the trade if the options are going to go in the money so you do not have to handle the sold options. The detailed process of closing a diagonal spread is below for your reference.

Place a buy-to-close (BTC) order on the sold contract that is about to expire. The rule is to prioritize the close on the short side of a diagonal trade for the sake of margin requirement.
Measure the profit potential of the remaining long option in the trade. You should identify whether the underlying asset moves in the right direction or not. The expectation of the rise comes with a call contract while put options brag the forecast of the downfall.
Place a sell-to-close (STC) order on the remaining options in the trade. You can complete the process by or at the expiration day of that particular option.

How Implied Volatility Impacts Double Diagonals

We should learn what implied volatility (IV) and double diagonals are before finding the answer.

Implied volatility (IV) is a metric gauging the possibility of changes in a security’s price from the market’s perspective to foresee the next price actions and the volume. Thus, they can ease the process of pricing options contracts.

On the other hand, double diagonals indicate the blending of a diagonal call spread and a diagonal put spread to gain the best out of the time decay.

Maximum Profit Potential

Accurate calculation of maximal profit potential by a diagonal spread is not an easy task. The received premium after the sale of the second put option might be the reason why.

When adopting the diagonal spread options trading strategy, your profits depend on the net credit after the sale of both put options at the latter strike price.

Profit Potential = Total Profit − Premium Paid for the Put Option − Initial Strike Price

Maximum Loss/Risk

Calculating maximum potential profits is difficult, and the measure of maximum risk is no exception. The risk of using diagonal spreads is now under the influence of strike prices and net credit.

Case 1 – Net Credit: You can calculate the maximum level of losses through the formula below.

Maximum Risk = Strike Price A − Strike Price B − Received Net Credit

Case 2 – Net Debit: You can use the following formula to estimate the maximum risk.

Maximum Risk = Strike Price A − Strike Price B + Paid Net Debit
