To your knowledge, were they more prone to break their rules for entry or for exit?
Adding to what I wrote in my preceding post, and building on what you wrote, the longer the term of the directional bias, perhaps the more pesky that unbiased protective stops appear. And so they are promptly disregarded when they get in the way because of the trader's unyielding adherence to the "big picture." (Of course, the trader can exit and then re-enter, but that's not what we're talking about here.)I don't have a large enough sample to make any definitive comment, but the rule-breaking tended toward exit. This of course is highly related to bias toward the direction and ultimate "target" of the move, which is also tied up with ego.

I agree. We must account for the potholes along the way.Keeping one's focus on the horizon doesn't prevent him from stepping into or falling into a hole. One of Wyckoff's major contributions was his approach to monitoring trend every step of the way rather than focus on some ultimate price objective. If one husbands the progress, the trend will take care of itself.
