About Louis B. Mendelsohn
The effects of Louis Mendelsohn’s research and application of computing technologies on technical analysis and the trading world are immeasurable. In addition to pioneering the application of personal computers and trading software to the financial markets beginning in 1979, he has remained at the forefront of the trading software industry for almost four decades.
After growing up in a public housing project and tenements in Providence, Rhode Island in the 1950s and ‘60s, Mr. Mendelsohn went on to receive a bachelor’s degree from Carnegie Mellon University, an MSW from SUNY Buffalo and an MBA with Honors from Boston University.
He began trading stocks and options in the early 1970s as a hobby while in graduate school, before turning his attention to the commodity futures markets. This was back when traders were limited to hand drawing daily prices and trend lines on charts and price quotes came from the newspaper. But soon after becoming a hospital administrator in 1977, Mr. Mendelsohn realized that technical analysis and trading could be revolutionized through the development of trading software for personal computers to help traders like himself make more profitable and timely trading decisions. Two years later, in 1979 he founded his trading software company for this purpose.
Louis Mendelsohn led, others followed
In May 1983 he released ProfitTaker, the world’s first commercially available technical analysis trading software to perform strategy back testing and optimization on PCs. Mr. Mendelsohn garnered significant favorable media exposure which set off a competitive arms race of trading software programs modeled after ProfitTaker, thereby laying the foundation for today’s multi-million dollar technical analysis trading software industry.
In the mid-1980s, Mr. Mendelsohn noticed subtle structural changes occurring within the global financial markets. This phenomenon involved the dynamic interconnections between related global markets that he believed, if quantified and incorporated into computerized trading strategies, had the potential to totally transform technical analysis from its historically narrow, single market focus of analyzing each individual market by itself, into a broader, global, multi-market or ‘intermarket’ analytic framework.
Paving the way to 21st century market realities
By 1986 Mr. Mendelsohn had developed an entirely new approach to computerized technical analysis by creating leading technical indicators that could give traders an advanced warning of impending trend changes in a specific target market (based on these new intermarket dynamics) before they actually took place.
Amid the global turmoil following the October 1987 stock market crash, Mr. Mendelsohn released the first commercially available intermarket analysis software in the world for PCs. This software analyzed the global interconnections of financial markets and provided trend direction forecasts that were based on how the markets affected each other.
Shortly afterwards, he began applying an artificial intelligence capability known as neural networks to global intermarket data to find hidden patterns and relationships in global market data and then used these patterns to predict future prices and trend directions of various global financial markets. This led to his introduction in 1991 of VantagePoint Intermarket Analysis software.
Patented Technologies and their Practical Application Cements Mendelsohn’s Legacy
Mr. Mendelsohn has continued to be the driving force behind innovations in technical analysis trading software. He was granted two patents in 2013 for the technologies that combine intermarket analysis with neural networks to create leading technical indicators that forecast global markets with uncanny accuracy.
Married to his wife, Illyce, since 1976, they have raised three sons and reside on their secluded horse ranch near Tampa, Florida.
