We must understand our present behavior in order to judge what we need to do to make changes in our trading style if any at all. A person will make the same mistake again and again if there is not a properly learned reaction to a particular consequence of an event. We must know the right and wrong reaction before we can make any judgement as to what is correct for the situation. Most situations are pretty obvious as to what a proper reaction should be. Most traders assume that their reaction is proper in the consequence of what the market has done.
Some traders are better at knowing the correct behavior than others.
The correct behavior is a learned process and not one that is always obvious. Animals are easier to study than humans and I think that perhaps is a good reason for studying animal behavior. Take a simple action-reaction event for any animal and see what results come about. Let us say that your family dog has never known what hot meant. In the old days when stoves burned coal and cobs, my Grandfather would pick up the stove lid to put corn shucks and cobs in the stove to get the fire to flame a bit.
