Supportland provides several environments for testing trading software and exchanges, including an exchange simulation environment, KLS tech labs, TAM images, and Seniorland. Users can view live production prices and test order behavior in the exchange simulation environment. KLS tech labs allow installing gateways from scratch. TAM images provide blank machines for testing. Seniorland hosts connections to major exchanges but requires permission to access. Support is available via the Supportland SharePoint site or by email.
