Thomas DeMark

Thomas DeMark spent decades developing proprietary market timing indicators, most notably TD Sequential and TD Combo, which attempt to identify price exhaustion at market turning points. His methods are used by hedge funds, sovereign wealth funds, and reportedly central banks. He has consulted for George Soros's Quantum Fund, Steven Cohen, and other high-profile institutional investors. DeMark Analytics licenses his indicators to Bloomberg and Reuters terminals worldwide. His approach differs from classical technical analysis by using countdown sequences rather than pattern recognition. By building his indicators around sequential counting mechanisms rather than subjective pattern matching, DeMark created a more systematic and replicable framework for identifying potential turning points — allowing his methods to be applied consistently by traders with different levels of chart-reading experience, and contributing to the broader institutionalization of rule-based technical analysis.
