I do believe whatever you have said, some people can easily overcome their childhood beliefs and do whatever they want. I have been a person who can’t decide, always in dilemma. That I can see in my trade too.
this all is overrated stuff .what happened in your childhood etc etc has no bearing on you and what you are doing today in trading. the more you get into such stuff or freudian psychology the more you will make it difficult for yourself to be successful in trading.
whatever is happening to you in trading is what you wanted to happen plain and simple. you have plan and if you are not following it that means you dont want to follow it (there is no other reason i see that we are ok with losses but dont want to follow a simple plan to make profits in traidng ). it has nothing to do with your childhood beliefs. i dont want to dig such thing more as it become lengthy discussions BUT.....
if you or anybody else want to give so much emphasis on psychology read and study
Adlerian psychology (chances are you or most of the ppl are not even aware of this) , wonderful stuff and practical. apply its, very easy and enjoyable .
