Found this interview with Tom DeMark while surfing around – DeMark has always stressed:

• “My method is anti-trend, contratrend, it’s pattern recognition and price exhaustion.”
• “Make certain you’ve made your technique objective – it should be a definitive process.”
• Although, also – “Good discipline, a knowledge of limitations and good money management are more critical than the system or indicator.”

He also says that he retired on leaving business grad school – markets & investment have been a retirement hobby ever since, and not a proper job at all… Think I know what he means, sort of….
