How it works

The inverse butterfly: collect a small credit that is kept if price finishes away from the middle strike.

When to use it

You expect a pin to FAIL — e.g. fading an expected expiry pin.

Risks & management

Risk exceeds the credit if price lands on the body. Small numbers on both sides; fees matter.
