Your question is very vague, so this is the best I can do. https://www.lightspeed.com/trading-education-center/short-call-butterfly/ Bob
Honestly, with respect, you're a little lazy. When you look at this graph, when does it tell you, you should sell this spread? Where do you make money, if the stock does what? Where do you lose? Under what expectations would you sell a butterfly vs buy? What strikes would you choose and why? This is not hard but I'm not going to tell you.
This has failure written all over it. -Zero intellectual curiosity -Feeling of entitlement -Apply short butterfly to EVERYTHING Doomed.
