Hi Loki...It sounds like your already well on the way to grasping the concept of trading. Just keep moving in the direction your going and you'll get there. For someone who's just starting out, your asking all the right questions!
Okay,Loki...concerning the "EDGE",I'm gonna give another quote from another very good book..."The New Market Wizards" (by same guy) J.D.Schwager. I'd give you my own opinion but this guy
puts it in words a whole lot better.
"You can't win without an edge." "To have an edge,you must have a method. The type of method is irrevelant. Some of the supertraders are pure fundamentalists;some are pure technicians; and some are hybrids. Even within each group, there are tremendous variations. For example, within the group of technicians,there are tape readers (or their modern-day equivalent--screen watchers), chartists, mechanical system traders, Elliot Wave analysts, and so on. The type of method is not important, but having one is critical--and, of course, the method must have an edge."...J.D.Schwager
What he's saying is,your "edge" is a method that works for you. Find something that your comfortable with, something you believe in.
"And remember that your playing against tens of thousands of professionals. Why should you be any better?"...J.D.Schwager
I'm out there, too Loki, and I'll do everything I can to get your money before you get mine. Hope this helps.
