http://www.tradersnarrative.com/jac...method-971.html One sure sign of a Pseudo-expert is writing that is unclear and difficult to follow. Unclear writing comes from unclear thinking. A true expert will be able to explain complicated ideas in ways that are clear and easy to understand. That made me think of one person: Jack Hershey. If youâve been on any sort of trading messageboard long enough, either he or his incomprehensible system will pop up eventually. Some think it is the key to the market. He certainly claims mastery - although he has provided nary a shred of evidence.
