Long Butterfly Calculator

The Long Butterfly Calculator lets you build your long butterfly strategy on any US equity ticker and visualize the P/L and Greeks on the same chart. The chart gets updated instantly as you iterate on the strategy, and you can modify the implied volatility assumptions for every leg individually.

To get you started, a long butterfly on SPY is modeled on the calculator. Simply change to your own ticker and modify the expiry and strikes to visualize your own strategy.
