HaasOnline Trade Server (HTS) is a locally installed platform that is currently designed to run on the Windows operating system 24/7, but we also support MacOS and Linux. In order to run HTS be sure to check the technical specifications of the machine that you would install our software on. HTS does not use many resources, but it has to be able to handle the price updates quickly, so its important to at least have a quad-core computer.
