I consider yesterday's experience of watching my profits explode higher while being unable to trade due to the computer/trading platform being slammed to be really dreadful. I never want to go through anything like that again if I can help it.
Yesterday I got myself the fastest laptop I could find, and its sole purpose in life is as my execution platform. So now I've got three separate computers, five separate monitors, two Internet connections on a special router for redundancy, and a battery backup. God help me if I'm going to let technology get in the way of trading. Never again.
