 In 1988, The Wall Street Journal wrote, “CRT’s secret is a computer system that uses one of the most sophisticated trading models in the securities industry.By monitoring differences in the options and futures prices, the model developed mainly by Mr. Ritchie, the firm executed more than $2.5 billion in trades each day.”

During a period in the 1980s, CRT was doing more options trading than any other firm in the world.In a 1986 article “These Traders Made All-Star by Hitting Singles,” Business Week reported “Those singles, razor-thin-profits on millions of transactions each year, makes CRT a perennial all-star.” CRT monitored those millions of transactions with a computerized system that was far ahead of the curve.
