Seagull Option

A three-legged option strategy, often used in forex trading, that can provide a hedge against the undesired movement of an underlying asset. A seagull option is structured through the purchase of a call spread and the sale of a put option (or vice versa).



The option contracts must be in equal amounts and are normally priced to produce a zero premium. This structure is appropriate when volatility is high but expected to fall, and the price is expected to trade with a lack of certainty on direction.

In the second example above, a hedger purchases a seagull option structured as the purchase of a call spread (two calls), financed by the sale of one out-of-the-money put, ideally to create a zero-premium structure. This is also known as a "long seagull." The hedger benefits from a move up in the underlying asset's price, which is limited by the short call's strike price.
