| Curtis Arnold is a veteran of the stocks and commodities markets. His first book, Your Personal Computer Can Make You Rich in Stocks and Commodities, sold over 50,000 copies and contained the actual code for twenty-five programs that would create and plot technical indicators.|
His next book, Timing the Market (1984), sold nearly 70,000 copies worldwide.
Changing Times magazine chose Timing the Market as the best investment book of the year in 1992.
In 1994, the book made the best-seller list in India. Curtis developed the Commitment of Traders Index, a tool that allows traders to spot imbalances in futures open interest among small, large, and commercial speculators. In 1987, Curtis' research led him to quantify and classify classical chart patterns, then produce accurate statistics, rating each for its probabilities of success.
This led Curtis to develop his PPS System (Pattern Probability Strategy), one of today's more successful and popular trading systems. After tripling his personal account in 1988, Curtis began training a limited number of students in his methodology.
In 1992, one of his students became the number-one-ranked CTA in the country.
That same year, a first-year PPS student won the United States Investing Championship with a return of 216.1 percent. Supertraders Almanac then chose PPS as "Trading Methodology of the Year."
