Biography

Mark D. Cook was an American trader, best known for his contributions to the financial markets through his self-developed trading strategies and mentoring. Born in 1954, Cook gained fame in the 1990s after winning the prestigious U.S. Investment Championship in 1992 with an astounding return of 563.8%. He began trading in the late 1970s and, after struggling for several years, honed a unique style focused on options and technical analysis, which culminated in the creation of his proprietary Cook Cumulative Tick indicator. This indicator helped him predict market reversals, particularly during high-volatility periods. Cook operated from his farmhouse in Ohio, managing his accounts and offering advisory services. His approach to trading was characterized by discipline, risk management, and consistency, traits he passed on to students through mentoring and seminars. In addition to his trading career, Cook was featured in Jack Schwager’s Stock Market Wizards and authored several articles for major financial publications.

Trading Strategy

Mark Cook’s core tool is the Cook Cumulative Tick (CCT), a running total of NYSE tick readings. He waits for extreme prints—usually beyond ±1 400—then looks to fade the prevailing intraday trend in S&P 500 futures if two confirming indicators agree: a three-day cycle oscillator and a five-day moving-average channel.

Cook scales into the trade in thirds so he can tighten stops progressively, and he often sells out-of-the-money options to finance a hedge while the future is open. He ignores signals that appear during thin midday volume, exits on the first sign of momentum divergence, and finds that reversals after a CCT spike rarely last more than one or two sessions.
