I was going through an old presentation (from 2010) and I had a slide on "Awareness" and whether you're being honest with yourself and whether you can handle the truth. I had written some notes on the slide which were as follows:
A major problem for some traders is a flawed strategy. The flawed strategy is due to incorrect assumptions. The incorrect assumptions are based on inaccurate beliefs. The inaccurate beliefs are often rooted in biases. So check to see if your biases are the main cause of your trading problems.
Ken Fisher once said "What do you believe that is actually false?" and "What the heck is my brain doing to blindside me?"
Let the market tell you what it is doing. Do not tell it what it should do. It does what it wants and is often not rational. Often it moves in a direction that seems contrary to logic given the economic situation and world events at the time. Therefore, think of the market as completely independent of everything else.
