Short Butterfly
When the market is either below A or above C and position is overpriced with a month or so left. Or when only a few weeks are left, market is near B, and you expect an imminent move in either direction.
Overview
Pattern evolution:
When to use: When the market is either below A or above C and position is overpriced with a month or so left. Or when only a few weeks are left, market is near B, and you expect an imminent move in either direction.
Profit characteristics: Maximum profit equals the credit at which spread is established. Occurs when market, at expiration, is below A or above C, thus making all options in-the-money or all options out-of-the-money.
Loss characteristics: Maximum loss occurs if market is at B at expiration. Amount of that loss is B – A – credit received when setting up position. Break-evens are at A + initial credit and C – initial credit.
Decay characteristics: Decay negligible until final month, during which distinctive pattern of butterfly forms. Maximum loss acceleration is at B.

Example
Scenario:
This trader currently has a #19 Call Ratio Backspread, but now feels that the underlying futures will not explode on the upside. Instead, the trader feels that the market has an equal chance of going up or down, and thus converts the position into a short butterfly.
