..... For the second question, I believe you have an edge when you are confident in your system. I think it's hard to be confident in these volatile markets if you have a system that isn't profittable! [/B]
I don't think being confident is an edge. It may lead to having an edge but it by itself is not an edge.
For example, I can be very confident that I can beat the heck out of Mike Tyson in a fist fight. But confidence can be just hallucination not reality.
If your systems/methods can lead to >50% winning over the long haul, then you can be confident of your systems/methods.
