A peak performance trader is totally committed to being the best and doing whatever it takes to be the best. He feels totally responsible for whatever happens and thus can learn from mistakes. These people typically have a working business plan for trading because they treat trading as a business.
A good way to deal with part of this psychological obstacle is to grade your setups. Please take a look at each of them and assign them a letter grade according to how good or how bad they are. At least this way, you’ll know how prepared or unprepared for a trade you were. It will also help to accept that even an A+ rated setup is no guarantee for success.
