Comparing mechanics, risk profiles, leg structures, and profit conditions to help you select the optimal trade setup.
**Bullish Butterfly** is tailored for Uptrend (Bullish) market outlooks (Low IV), while **Calendar Spread** excels in Sideways / Range-Bound market environments (Low IV expecting expansion). Choose based on your market bias and volatility expectations.
A precision play — you're not just bullish, you have a specific price target in mind. Buy a lower strike, sell two at your target, buy one further out. Cheap to enter, big payout if the stock lands exactly where you expect.
A time-decay play at its core. Sell a near-term option, buy a longer-term one at the same strike, and let the faster decay on your short leg outpace your long leg while the stock hovers near that strike.
