Comparing mechanics, risk profiles, leg structures, and profit conditions to help you select the optimal trade setup.
**Bullish Calendar Spread** is tailored for Uptrend (Bullish) market outlooks (Low IV expecting IV Expansion), while **Neutral Diagonal Spread** excels in Sideways / Range-Bound market environments (Mixed IV). Choose based on your market bias and volatility expectations.
Sell a near-term call and buy a longer-term call at the same OTM strike. You're betting time decay hits your short call faster than your long call, while positioning for the stock to drift up toward that strike over time.
A calendar spread's cousin with different strikes instead of matching ones. Buy a further-dated call at a lower strike, sell a near-dated call at a higher strike — built to profit if the stock stays inside a defined corridor.
