Double Calendar

The most common structure is mixed: put calendar at the lower strike and call calendar at the upper strike. This matches natural put/call placement (puts protect downside, calls at upside resistance). However, you can use all calls or all puts - the theoretical payoff is similar due to put-call parity.

Base it on the expected trading range. Typically 3-5% apart works well. Place strikes at identifiable support and resistance levels. Wider spacing gives more room for error but lower max profit. Narrower spacing offers higher profit but requires more precision.

This is still profitable! It's the 'valley' of the payoff curve. While not maximum profit (which occurs at either strike), the position is profitable when price is between strikes. The valley is a feature, not a bug - it means you profit across a wide range.

Not exactly. Maximum loss is double (since you pay double the debit), but the profit zone is wider. Risk-adjusted, they're similar. However, gamma risk IS doubled near expiration because you have two short front month options. This is the key risk to manage.

For a standard double calendar with proper structure, maximum loss is limited to the total debit paid. This occurs when price moves far outside both strikes. Always verify your structure is correct before trading.

Roll when: Price is within range, thesis unchanged, and rolling provides credit or minimal cost. Close when: Price has broken out of range, thesis is broken, or you've achieved acceptable profit. Key question: Would you enter fresh at current prices?

If price breaks through one strike: (1) Consider closing the calendar that's now far from price (it's losing), (2) Keep the calendar closer to price or roll it to follow, (3) Or close entire position if thesis is broken. The goal is to reduce loss on the losing side while maximizing remaining opportunity.

You'll be left with just the back month long options. The short front month options will expire (worthless if OTM, or assigned if ITM). For equity options, assignment can occur. For index options, cash settlement. It's cleaner to close or roll before expiration.

Critical: If earnings falls between your expirations, IV dynamics become unpredictable. Front month IV may spike (hurting your short positions) or back month may not expand as expected. Either have both expirations on same side of earnings, or avoid the period entirely.

Yes. You can close one calendar and keep the other, effectively converting to a single calendar. This is useful when price has clearly moved toward one side and you want to reduce exposure to the losing side while maintaining the working side.

Analyze: (1) Ensure contango on both put and call term structures, (2) Compare front vs back month IV differentials, (3) Monitor for term structure changes during the trade, (4) Consider events that might distort term structure. Enter when term structure favors time spreads on both sides.

Use asymmetric sizing when you have a slight directional bias within the range. For example, if you think price is more likely to drift toward the lower strike, put 2 contracts on the lower calendar and 1 on the upper. This skews your profit potential toward your bias while maintaining range coverage.

Options: (1) Trade the underlying to neutralize delta, (2) Close the threatened calendar to reduce directional exposure, (3) Roll the threatened calendar to follow price, (4) Add a vertical spread to offset delta. For most traders, simply adjusting position via closing or rolling is more practical than active delta hedging.

Limit each double calendar to 2-3% of portfolio value based on total debit. Since max loss is total debit, this caps any single position loss. Spread across multiple underlyings for diversification. Account for correlated positions that might move together.

Iron condor: Single expiration, short vega (benefits from IV contraction), positive theta, easier to manage. Double calendar: Multiple expirations, long vega (benefits from IV expansion), positive theta, requires managing time spread. Choose iron condor when IV is high; choose double calendar when IV is low. Both profit from range-bound behavior.
