A system and method are provided to analyze synthetic and real markets that offer interchangeable tradable objects to find market opportunities that a trader may capitalize on. A synthetic market is an electronic market created out of real markets by a computer terminal or gateway. A real market is an electronic market that is offered by an electronic exchange. If a desirable market opportunity is found, the preferred embodiments can take action such as by sending orders to either one of the markets, or by sending orders to both markets. An advantage of the preferred embodiments, among many others, is that they can make “invisible” trading opportunities more readily apparent.
