STRANGLE
1. As with a straddle, the sale or purchase of a put option and a call option on the same instrument, with the same expiry, but at strike prices that are out-of-the-money. The strangle costs less than the straddle because both options are out-of-the-money, but profits are only generated if the underlying moves dramatically, and the break-even is worse than for a straddle. Sellers of strangles make money in the range between the two strike prices, but lose if the price moves outside the break-even range (the strike prices plus the premium received).
2. The term strangle is also used, by currency option traders, to denote the average difference in implied volatility between out-of-the-money call and put options with a 25% delta and the implied volatility of at-the-money forward options.
