Louis B. Mendelsohn

Louis B. Mendelsohn, a pioneer in the application of personal computers to the financial markets, is President and Chief Executive Officer of Market Technologies, LLC, which he founded in 1979 to develop technical analysis trading software for use by commodity futures traders.

Mendelsohn began trading individual in the early 1970s, followed by . Then, in the late 1970s, while working as a hospital administrator, he switched to commodities, as both a day and position trader, and began utilizing personal computers in his technical analysis research.

In 1980 he left the hospital administration industry to trade full-time and continue his research at applying personal computers to technical analysis. Three years later, Mr. Mendelsohn pioneered the first commercially available strategy backtesting and optimization trading software for personal computers. By the mid-1980s these capabilities had become the standard in technical analysis software for both stock and futures traders.

Recognizing the emerging trend toward globalization of the world's financial markets, in 1983 Mendelsohn again broke new ground in technical analysis when he developed the first commercial intermarket analysis software in the financial industry for personal computers. Mendelsohn shared his early work with the trading community via an article in Commodities (now Futures) magazine in 1983, which focused on how an individual trader could utilize the power of personal computers to create, backtest and perfect trading methodologies.

Mendelsohn created and distributed the ProfitTaker Futures Trading Software in 1983. At the time, ProfitTaker was the first widely available trading strategy backtesting and optimization software for individual use, in the trading industry. The software offered unique options including trading triggers for both long and short plays that worked in conjunction with moving averages.

The inner dynamics of how commodity futures markets work, such as the roll from one contract month to another amid expiration, added a new layer of depth and challenge to anyone working with or creating personal computer trading software. Mendelsohn faced these challenges head on and created solutions to handle these commodity-market specific problems within his early software.
