I'm a trader moving my office to my home. I know almost nothing about what goes on behind my computer screens as far as "tech" goes. I need to sit down with a professional, explain my needs, front end software usages, and then get help configuring the computer that I would order. When it arrives 2 weeks later, he or she can hook it all up at my house. Low latency is a must - most of the opportunities I go for are being looked at by others, and manual (mouse) entry is mandatory on these markets. Who in Chicago can do something like this? The existing tech guy at my trading office shrugs his shoulders on some issues. The "Geek Squad" (from Best Buy?) won't know trading. People think they know stuff, and then can't answer questions.
