Occasionally traders will ask me for suggestions on computers to use for trading. I do not recommend any "made for traders" high-end special systems. For swing trading, I like to use any modern decent-quality computer; one doesn't need multiple monitors for that. I've done swing trades from my laptop on the road.

For day trading, I use 4 24" widescreen monitors. I build my own computers, using components from newegg.com . I like an ASUS large motherboard, large case, 2 dualhead Nvidia pci-e graphics cards, a SSD samsung solid state main hard drive, and 16Gb memory.
