There are only two types of technology professional futures traders will use. Patsystems is one of them. All other trading technologies are not considered sufficiently reliable or fast. In addition they are the only types of technology that work on the basis of tick-by-tick prices. These are essential for optimal order execution. They are also essential if you want to implement (semi)-automated strategies.
One single tick in your favour on, say, an Eurostoxx 50 future execution equals a net gain of € 10.
