Market Insights

Balancing directional bias with premium collection isn’t always straightforward, even for the most dedicated options traders. Diagonal spreads stand out as a sophisticated strategy that might allow you to potentially profit from time decay, volatility shifts, and price movement simultaneously.

The diagonal spread is a multi-leg options play that blends elements of vertical and calendar spreads, helping you position for bullish or bearish moves with more flexibility, while managing risk and premium collection. Paired with TradeStation’s advanced tools, you can identify candidates, analyze risk profiles, and manage these positions more efficiently.

 

How diagonal options spreads work

A diagonal spread consists of two option contracts of the same type (calls or puts) with different strike prices and expiration dates:

The two legs:

Buy a longer-term option (typically 60-90 days out)

Sell a shorter-term option (typically 30-45 days out)

The long option provides staying power and defines your maximum loss. The short option generates premium income and benefits from accelerated time decay. Unlike vertical spreads, where both options expire simultaneously, the short option in a diagonal spread expires first, potentially allowing you to sell another short-term option against your still-open long position.

 

Understanding diagonal spread strategies and variations

A diagonal option spread is constructed by buying and selling calls or puts on the same underlying asset, but with differing strike prices and expirations. This hybrid structure blends the vertical spread’s strike-based approach with the calendar spread’s expiry-based setup.

Diagonal spreads stand out by offering both strike and expiry flexibility, unlike calendar spreads, which use the same strike price but different expirations, and vertical spreads, which use the same expiration but different strikes.

• A diagonal call spread is typically used when expecting a moderate rise in the underlying asset. You buy a longer-term call at a lower strike and sell a shorter-term call at a higher strike. This setup is typically bullish, benefiting from upward price movement and time decay on the short leg.

• A diagonal put spread is often for bearish or income-focused scenarios. You buy a longer-term put at a higher strike and sell a shorter-term put at a lower strike, aiming to profit from a decline in the underlying asset.
• Debit diagonal spreads require a net premium outlay, with risk limited to the premium paid. Profit potential depends on favorable price movement and time decay.
• Credit diagonal spreads generate a net premium, with risk defined by the spread width minus the premium collected.

The beauty lies in their adaptability. After the short option expires or is closed, traders can potentially sell another option against their long position, a process that can be repeated multiple times.  This versatility allows you to customize risk/reward profiles, adjust to changing market conditions, and manage exposure to both price and volatility strategically.

 

Profit potential and risk/reward analysis

Diagonal spreads aim to generate profit through a combination of premium collection and favorable price movement. Unlike strategies with fixed profit and loss, diagonal spreads have variable risk profiles that depend on when you close the position.

For credit diagonal spreads, the initial credit collected represents potential profit if the short option expires worthless. Maximum profit for debit spreads occurs when the underlying moves favorably and the long option gains intrinsic value while the short option expires worthless or loses value quickly.

 

Maximum profit: Variable and dependent on timing of exit. For credit spreads, initial credit collected if short option expires worthless. For debit spreads, the gain from the long option’s appreciation minus the debit paid.

Maximum loss: For debit spreads, the premium paid is the maximum risk if both options expire worthless. For credit spreads, maximum loss is the width of the spread minus the credit received if both legs are closed at the short option’s expiration.

 

Assignment risk exists with diagonal spreads. If assigned on a short put, you must purchase shares at the strike price. Assignment on a short call requires delivering shares. Your long option provides protection and can be exercised to fulfill assignment obligations.

Managing and adjusting diagonal spreads

Rolling represents one of your most valuable adjustment techniques. When your short-term option approaches expiration, you can close it and open a new short option with a later expiration date. If the short option expires out-of-the-money, you can repeat this process, potentially multiple times, against your still-open long position.

The rolling process is straightforward in TradeStation’s OptionStation® Pro. You can close your short option, then sell a new option 30-45 days out against your long position. The ability to execute multi-leg orders as single transactions simplifies this process significantly.

Consider using TradeStation’s Activation Rule Tool to automate certain management decisions. You can set conditional orders that trigger if the underlying breaches specific price levels or if your position reaches predetermined profit or loss thresholds. This feature proves particularly valuable for diagonal spreads, which can move quickly as expiration approaches for the short leg.

 

Building a bull put diagonal spread

Constructing a diagonal spread starts with selecting optimal strikes and expirations. You’ll want to consider your market outlook, implied volatility, and liquidity. TradeStation’s RadarScreen® can help make this process straightforward.

Once you’ve identified a candidate, use the Matrix tool to analyze market depth and order flow. This helps you visualize bid/ask spreads and assess fill quality, reducing slippage and execution risk.

Let’s walk through a step-by-step example of constructing a diagonal call spread on our platform.

1. After filtering S&P 500 components in RadarScreen for bullish technical setups, a stock appears as a candidate trading at $90.
2. To construct the bull put diagonal, you buy a 60-day put at the $85 strike and sell a 30-day put at the $95 strike. This generates a credit of $0.60, or $60 per spread. The position benefits if the stock stays above $95 through the near-term expiration.
3. Opening this position in OptionStation Pro, you can view the risk profile visualization. If closed at the short put’s expiration with the stock above $95, your risk would be $9.40 ($940 per spread), which is the $10 difference between strikes minus the $0.60 credit received.

The ideal outcome has the $95 put expiring worthless, allowing you to keep the $60 premium. If you remain bullish, you could sell another 30-day put against your long $85 put, perhaps at the $95 or $90 strike, depending on where the stock trades. This rolling approach aims to collect enough premium over time to potentially create a profitable position.

If the stock drops below $95 as expiration approaches, you might close both legs early to minimize loss, or roll the short put to a later date or different strike. The Activation Rule Tool can automatically trigger protective actions if the stock breaches your predefined levels.
