Louis B. Mendelsohn is president and chief executive officer of Market Technologies. He founded the firm in 1979 to develop technical analysis trading software for commodity futures markets.[1] He's focused his career on the creation of the application of personal computers and trading software to the global financial markets.


Mendelsohn himself began trading equities and stock options in the early 1970s. Then, in the late 1970s he switched to commodities, as both a day and position trader, and developed trading software for the commodities futures markets.

In 1983, Mendelsohn authored a series of articles in Futures Magazine in which he outlined his vision for strategy back testing and optimization for personal computers. That same year he introduced ProfitTaker Futures Trading Software, commercially available strategy back-testing trading software for personal computers.[2]

Following the October of 1987, Mendelsohn introduced the first commercially available PC software in the financial industry to address the emerging globalization of the financial markets through the application of intermarket analysis in trading software. Several years later, in 1991, he introduced his second generation intermarket analysis software program, VantagePoint Intermarket Analysis Software, which applies the pattern recognition capabilities of artificial intelligence to global intermarket data, and quantifies the effects of related global markets on each other in order to make short-term market forecasts.[3]

Since then, Mendelsohn along with his research and development team, The Predictive Technologies Group, has been focused on the accelerating globalization of the financial markets and worked to make improvements to VantagePoint’s predictive accuracy.[4]


Mendelsohn received a B.S. degree in Administration and Management Science from Carnegie Mellon University's Tepper School of Business in 1969, a MSW degree from the State University of New York at Buffalo in 1973, and an MBA degree with Honors from Boston University in 1977.
