It is the same with trading. Ok we watched behavior and next we would tell the group of would-be traders that they would have to stand back because the elevator would be packed with people getting off. They became so good that they didn't even care to anticipate which elevator would be up first. In this case it worked for them because it is what they were told. Again, not to repeat myself but it is necessary to say it is the same in trading.
Traders mostly change their behavior by what they are told.
The answer of course is no, not at all. A trader must learn from research what the proper behavior modification is in all possible situations. This takes lots of inner soul searching and market data to understand what behavior takes them to the threshold of successful behavior in trading. You are most likely seeing my reason for stating that knowledge and behavior modification are required for successful trading. It never is an addressed issue in trading when a trader opens an account as to what their behavior might be.
