Double Diagonal

No. An iron condor has all legs in the same expiration. A double diagonal has short options in a near-term (front) month and long options in a later (back) month. This multi-expiration structure allows for rolling and different Greek exposures.

Double diagonals allow multiple rolling opportunities (harvest theta repeatedly), have net long vega (benefit from IV increases), and offer more flexibility to adjust strikes each cycle. Iron condors are simpler but are one-time trades.

Typically 2-3 times, limited by when your back month options approach expiration (21 DTE). Each roll should ideally generate credit. Close the entire position when back month reaches 21 DTE.

Roll or close before expiration to avoid assignment. If it goes significantly ITM, you may need to close that side at a loss. Your long option provides some protection but only within the width of the diagonal.

Profit potential depends on how many successful rolls you complete. If initial debit is $1.30 and you collect $0.55 per roll for 3 rolls = $1.65 total credits. Minus debit = $0.35 profit plus remaining long value. Target is typically 30-50% of initial debit.

Contango (back month IV > front month IV) is favorable - you're selling relatively expensive front month and buying relatively cheaper back month. Backwardation (front > back) is unfavorable and suggests stressed markets. Check term structure before entry.

If the underlying moved significantly (>5%) from your entry, consider recentering your short strikes around the new price. This keeps your profit zone relevant. However, you can't move your long strikes, so adjustments are constrained.

Track cumulative credits: Initial debit + all roll credits/debits + current position value = total P&L. Use a spreadsheet to log each transaction. Your profit target should be based on recovering the initial debit plus a reasonable return.

IV drops hurt double diagonals due to net long vega. Monitor the position - if the loss is significant and IV is expected to stay low, consider closing. If you believe IV will rebound, hold. Severe IV crush may warrant early exit.

Yes. Make the put side closer to ATM for bullish bias, or call side closer for bearish bias. Asymmetric strikes express a directional view while maintaining the theta-harvesting structure.

Backtest across multiple periods varying: short delta (12-25), width (5-15), roll trigger (40-75% profit or DTE), and expiration differential (21-45 days). Test each parameter independently, then combined. Validate out-of-sample to avoid overfitting.

Track portfolio-level vega. DD adds long vega. Set a max portfolio vega limit (e.g., 2% of portfolio per 1% IV move). Balance DD long vega with short vega strategies (iron condors, naked premium). Consider VIX hedges for extreme scenarios.

Typically 10-30% of options capital. Consider opportunity cost - capital is tied up in debit. Reserve capital for rolls and adjustments. Compare return on capital to alternatives like iron condors. DD is capital-intensive but offers unique characteristics.

Front month typically has steeper skew (near-term fear priced higher). Selling steep front skew, owning flatter back skew captures relative value beyond pure theta. Monitor skew differential as it can change, especially around events.

Model scenarios: 10% drop (price and IV impact), 20-point IV spike (helps vega), 10-point IV crush (hurts vega), range-bound 60 days (ideal). Calculate P&L under each. Size positions so no single scenario causes unacceptable loss. Consider correlation with other portfolio positions.
