How it works

A call butterfly whose upper wing is placed further out: entered near credit, no downside risk, defined but larger risk above.

When to use it

Pin thesis where being wrong downward should cost nothing.

Risks & management

All the risk concentrates above the skipped wing; a rally through it hits the full widened width.
