Just about any off the shelf Core 2 duo computer nowadays is adequate for most daytraders. Probably the most important issue for daytraders is simply staying connnected, which I would like to discuss here. I've seen some terms such as Link Balancer and Load Balancer on this website. http://www.barracudanetworks.com/ns/products/balancers.php And dual wan (linksys) at this site. http://www.smallnetbuilder.com/content/view/30186/51/ Basically, I would like to setup a seamless internet connection, so that I'm very rarely disconnected. 1) Is this possible using both cable and DSL with a dual wan or link balancer setup? 2) Is there a difference between a dual wan and a link balancer? 3) Does a link balancer actually use both cable and DSL at the same time and optimize internet download/upload speeds? 4) Does using any of this hardware give you a completely seamless connection if your cable or dsl is disconnected, or is there some kind of delay? 5) Any recommendations on hardware to use? 6) Is a T1 connection a better alternative to the above?
