I would say this has a fair amount to do with the fact that people are so eager for a solution, when what they need to do is just spend time studying the market. Then add indicators with purpose, but I truly think MOST traders have no idea what a moving average represents, and have no idea what that would look like without an indicator.....
I think I found most of my edge in my waiting to trade. I took weeks off at a time just to watch crude, both the charts and the dom, as well as learning where my market fell in the hierarchy of the economy. Learn what a healthy trading day looks like, as well as a poor trading day.
For me to really be confident in a trade I want to see bonds, the euro, and equities in some sort of directional harmony.
After that its just define your risk, pick your entry and hold on tight.
