The Wide Area Network is the long-distance network connection that sits in-between your Local Network and the Exchange. Dedicated network connections between data center co-locations are the best way to ensure market executions you perform have the best possible latency.

The solution traders should use is a Private circuit – a dedicated piece of wire that runs in-between two data centers. This paper explains how to optimize your systems for low-latency trading.
