What is a Diagonal Spread Options Strategy?
A diagonal spread is an options strategy that involves simultaneously buying and selling options on the same underlying asset with different strike prices and different expiration dates. The long leg uses a longer-dated option to maintain directional exposure, while the short leg uses a shorter-dated option to generate income from accelerated time decay.
When using calls, a bullish diagonal spread is sometimes called a "poor man's covered call" because it mimics the covered call strategy at a fraction of the capital. The long LEAPS call replaces the stock position, while the short near-term call generates premium income.
How to Use This Diagonal Spread Optimizer

- 2
Select Your Market Outlook
Choose Bullish, Bearish, Neutral, Volatile, or Stable. This determines the option type (calls vs puts) and strike selection bias.

Set Risk Tolerance
Conservative narrows the strike range and favors higher reward/risk ratios. Aggressive widens the search for higher-profit opportunities.

Key Metrics Explained
Net Debit
The cost to enter the diagonal spread: long leg premium minus short leg premium, times 100 shares per contract. This is your capital at risk.
Composite Theta
Net time decay of the position. Positive Theta means you earn from time passing — the short leg decays faster than the long leg.
Composite Delta
Net directional exposure. Bullish spreads have positive Delta; bearish spreads have negative Delta. Neutral strategies target near-zero Delta.
Reward/Risk Ratio
Maximum profit divided by maximum loss. Higher ratios indicate more favorable risk-adjusted returns for the diagonal spread.
Composite Vega
Net sensitivity to implied volatility changes. Positive Vega benefits from rising IV; negative Vega benefits from falling IV.
Optimization Score
A composite ranking that weighs reward/risk, Greeks alignment with your outlook, Theta favorability, and option liquidity.
