Double Calendar

Run a Call Calendar and a Put Calendar side by side, both centered around the current price. The result is a wider 'tent' of profitability than a single calendar spread offers.

Strategy Masterclass & Guide

### What is a Double Calendar? Picture two calendar spreads running in parallel — one on the put side, one on the call side, both using OTM strikes bracketing the current price. This gives you a broader "tent" shape of profitability compared to a single calendar, which really only has one sweet spot. I like this one when I expect a quiet stretch but I'm not confident enough to pin an exact price the way an Iron Butterfly demands. It's a more forgiving neutral trade, at the cost of paying two debits instead of one.

Frequently Asked Questions about Double Calendar

A Double Calendar uses the same strike for both the near and far leg on each side; a Double Diagonal uses different strikes for the near and far legs. Double Calendars are simpler to manage but have a narrower "tent" than Double Diagonals.

Related Sideways / Range-Bound Strategies

🔁 Sideways / Range-Bound

Iron Condor

The bread-and-butter income trade for a range-bound market. Stack a Bear Call Spread on top of a Bull Put Spread, collect the combined credit, and let the stock chop sideways while theta pays you.

🔁 Sideways / Range-Bound

Iron Butterfly

The condor's tighter, higher-conviction cousin. Sell an ATM call and ATM put right at the money, buy OTM wings for protection. Bigger credit, but the stock needs to stay much closer to your center strike.

🔁 Sideways / Range-Bound

Short Straddle

As pure as premium-selling gets — sell an ATM call and an ATM put, same strike, same expiry. Maximum premium collected, but maximum exposure too if the stock decides to move hard in either direction.
