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 **Butterfly Spread (Call or Put)** excels in Sideways / Range-Bound market environments (Low 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.
Three strikes, a 1-2-1 ratio, and a sharp profit peak dead center. Cheap to put on, and when the stock actually pins near your middle strike at expiry, the reward-to-risk ratio can be excellent.
