I would like to return to my root and ask what I perceive as the most profound question: What is an edge? As a perma-noob, I'm always told that I must have an edge to succeed as a trader. So what is an edge exactly? Can it be defined? Is it quantifiable? Can it be repeated? Is it static or dynamic? So far, here's what I've manage to come up with: 1) Edge is a pattern. It could simply be a price pattern on the chart, or it could be a behavior pattern (eg. the interaction between me and/or the market). 2) Edge must be repeatable. It can be repeated, replicated, duplicated each and every day. 3) Edge has a high probability of success. . . . 4) Good entry is a must. Good exit is a must. 5) Good entry is useless, however, if your timing is off. 6) There is no good exit. There is only a proper exit (eg. let your winner run, cut your losses). . . .
