An options trade that uses 4 different contracts as part of a wider strategy to benefit from stocks or futures prices moving within a defined range. It is constructed similarly to a short-straddle trade, with a long call and long put option purchased for protection. The two call options and the two put options are spread over a series of 3 strike prices, all with the same expiration date. The objective is to profit from conditions where the price remains fairly stable and the options demonstrate declining volatility (implied and historical).
