Well, it has had to change cause of computerization eventually, it you think "retail" is going to be fastest than most or me, you can forget about it, has to be automation on one minute bars or lower. Best to go to day trading and going for more than ticks-like 2-20 points, plus those who use to teach scalping, extremely hard as you going to be another one to trade against.
We ALL have differences on experience and computer skills, where one does not see quality choices, others just trade. All depends on methods, time durations, contracts pushing, time of the hour, reports. I love automation now and always had fought doing it, just gives so much more time to test, ideas hardly ever stop-we doing what we love, the GAME.
