Here is my setup…. I daytrade futures from the open for about 3-4 hours. The type of daytrading that I do doesn’t need a fast internet or a fast computer, but my internet and computer are fast enough to minimize the lag time when I’m trading.
My systems have always been dell computers that are off the shelf. The current one is I7, 8 gig memory and a large hard drive. When trading, my cpu runs less than 10 percent, my memory usage is less than 4 gig and the hard drive uses less than 10%. In a few years, I will get a new computer and it will be I7 or better and 16gig memory. I trade with 18-20 charts and the only time that I see a lag in computer/internet/my broker is when there is a huge/quick move in the markets.
Cheers
