The key their volume though is they don't really have hard latency constraints. Most of the data flowing through the Terminal is still for human eye balls and inaccurate or laggy data is tolerated. It's not a low latency product. They do have an API offering but you're unlikely to find serious trading shops using it except as a backup feed.
