It is not when I lose much in one period, nor when I have a position or positions that include loss that I do not realize, yet, but when I am running a benefit-position(s) until I exit.
Such a situation makes me highly stressful, because there is a strong confrict beteween the feeling that I want to take profit(s) and to feel easy right now, and the feeling of endurance/patence to stick my system(s) for my discipline as a trader because I am a trader.
Resutly, to stick the system(s) makes more money than to exit based on my feeling(s). Of course, this is about total net profit to one period, so it can be naturally said that each trade, each taking-profit sometimes take more money than each mechanical-trading based on systems.
I am going to read ken long's article about discipline and meditation and to consider. And this weekend, I am plannning to read pdf of EBTA which Andrew told me in Van's forum, but I am going to read this slowly like a tortoise. Of course I appreciate both of them.
ken's web-site is the following.
