Long Butterfly
One of the few positions which may be entered advantageously in a long-term options series. Enter when, with one month or more to go, cost of the spread is 10 percent or less of B – A (20 percent if a strike exists between A and B).
Overview
Pattern evolution:

When to use: One of the few positions which may be entered advantageously in a long-term options series. Enter when, with one month or more to go, cost of the spread is 10 percent or less of B – A (20 percent if a strike exists between A and B). This is a rule of thumb; check theoretical values.
Profit characteristics: Maximum profit occurs if a market is at B at expiration. That profit would be B – A – net cost of spread. This profit develops, almost totally, in the last month.
Loss characteristics: Maximum loss, in either direction, is cost of spread. A very conservative trade, break-evens are at A + cost of spread and at C – cost of spread.
Decay characteristics: Decay negligible until final month, during which distinctive pattern of butterfly forms. Maximum profit growth is at B. If you are away from (A-C) range entering the last month, you may wish to liquidate position.
CATEGORY: Precision
Long call A, short 2 calls B, long call C
Long put A, short 2 puts B, long put C
Example

Scenario:
The trader currently has a #17 Ratio Call Spread. He thinks this is still a good position. However, he is worried that the futures may increase dramatically on the upside, leaving him with a substantial loss. He adds a long call and converts the position into a long butterfly.
