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 **Double Calendar** excels in Sideways / Range-Bound market environments (Low IV expecting IV rise). 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.
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.
