Quote from Gabe2004:
And how do you know that you are the problem and not a failed strategy?
If you don't let a strategy prove itself because of issues that YOU have, you cannot tell whether your strategy gives you an edge or not.
Sort of the chicken and the egg problem.

When we're talking about a basic methodology like trend lines, it's obvious that the logic of the strategy gives the "edge" -- the "edge" is just a greater probability that one thing will happen versus another. The basic nature of a channel or trend is such that an edge is inherent--the very definition of a trend gives the probabilities that continuation is greater than reversal--else, it couldn't be called a "trend."
The discretion involved in then entering, managing, and closing trades is where each individual trader comes in, and is why one trader can successfully trade a trend or channel or range, whereas another fails. The "edge" becomes the trader, and his discretionary decisions. In general, will he tend to make a trading decision such that price is more likely to move in his favor? This is the edge now. The trader, and his discretion. At that point, the psychology almost completely takes over, as issues with entering early, exiting early, late, and all those things are fundamental psychological issues, if they're discretionary and not mechanical.
What I'm saying in a nutshell is: a discretionary trader cannot separate the strategy from himself. His mindset and attitudes become his strategy, for all intents and purposes. These are just my beliefs of course, and not said to be "truth" -- it's just my truth.
