Diagonal Spread: Directional + Income, in One Structure

The diagonal spread is the closest thing options have to a swiss-army knife. It combines directional exposure (the long leg), income generation (the short leg), and time-decay asymmetry — all in one structure. It's also the structure most retail traders never use because it requires thinking in two dimensions instead of one.

The bullish diagonal call

• Buy one deep-ITM call (0.70+ delta), 60-120 DTE — your "long stock equivalent"
• Sell one OTM call at a higher strike, ~14-30 DTE — your weekly/monthly premium
• Net debit (long leg costs more than short leg credits)
• Profit if underlying drifts up moderately AND short leg expires worthless

Manage by rolling the short leg week-over-week. Each roll resets theta and brings in additional premium. The long leg appreciates if the underlying moves up; the rolling shorts amortize the cost.

The Poor Man's Covered Call

Specific named variant of the bullish diagonal call. Instead of buying 100 shares of $50 stock ($5,000 capital), buy a 6-month $40 call ($1,200 capital). Now sell weekly $52 calls against it. You're collecting the same weekly premium with 1/4 the capital tied up. The trade-off: the long call has theta (shares don't), and you cap your upside at the short strike.

The bearish diagonal put

• Buy one deep-ITM put (0.70+ delta short put), 60-120 DTE
• Sell one OTM put at a lower strike, ~14-30 DTE
• Net debit
• Profit if underlying drifts down moderately AND short leg expires worthless

Where OptionsDeck helps

Use the strategy builder to model multiple roll scenarios — what happens if the short leg gets tested, what happens if it expires worthless, what happens if the long leg's IV drops. Check the vol surface for term structure — a positive slope (back-month IV higher) is ideal because your long leg holds value while shorts decay. Read the dealer GEX to find a long strike near a dealer support / put wall.
