Evolution is about change… adaption… survival. For a thing to evolve, though, it needs a catalyst – an environmental shift of a substantial magnitude or a subtle mutation – that forces change to occur.
In the late 1970s, the magnitude of the newly introduced personal computer (PC) caused an environmental shift that forced change upon the world. Adapt or perish was the new reality for everyone. In the financial sector, this reality was equally true, except that a not-so-subtle mutation in technical analysis made adapting even more imperative. If those who traded markets did not adapt, they perished.
Recently, a number of trading publications have featured articles highlighting the evolution of technical analysis since the advent of personal computers nearly forty years ago. As history tells us, technical analysis evolved dramatically with the introduction of PC-based trading software and then again later as the global economy emerged and the world’s financial markets became increasingly interconnected.
One commodities trader turned trading-software developer has been on the leading edge of the evolution of technical analysis– Louis Mendelsohn. Working full time in the mid-to-late 1970s as a hospital administrator, while trading commodity futures contracts on the side, Mendelsohn fostered a new age in both technical analysis and trading software. His innovative work with PC-based trading software catalyzed the evolution of technical analysis. It transformed from hand-drawn charts derived from computing technical indicators on hand-held calculators, and software that merely automated these functions, to technical analysis calculated on powerful personal computers.
Prior to the use of trading software, charts were maintained by hand as shown in the nearby example. This is a handdrawn chart from Mendelsohn’s archives, circa 1979 tracking US Treasury Bill Futures from the days before computerized trading software.
Mendelsohn had a vision – he was determined to squeeze all the power from personal computers to produce technical analysis previously only available to traders at big trading firms with large research staffs and mainframe computers at their disposal. In 1979, at 31, he started Market Technologies to develop PC-based trading software for his own use and to license it to other like-minded commodities traders. Mendelsohn understood that the PC coupled with powerful analytic software would become the future for traders.
Mendelsohn unveiled his first new tool for traders in 1983, ProfitTaker Futures Trading Software. With that software, he introduced strategy back-testing for personal computers, an innovative and unprecedented approach to analyzing potential trades.
Other futures traders began to follow his approach, which he presented in a series of articles on trading software published in Futures magazine in 1983. He also presented his visionary ideas as a speaker and expert on technical analysis in panel discussions at international trading conferences. His expertise expanded and his influence spread. Hand-drawn charts and hand-held calculators for technical analysis would soon join Tyrannosaurus Rex as a relic of the past because of Mendelsohn’s vision. PC-based trading software would transform from mere automation of functions to a truly powerful tool. Mendelsohn worked with industry leaders to build a fully functional software package.

His strategy back-testing software, the first such commercially available software to offer this incredibly powerful capability at the PC level, furthered the evolution of technical analysis and energized the growth of what would soon become a multi-million dollar trading-software industry, an industry built in large part on Mendelsohn’s pioneering innovations.
During the incubation period for PC-based trading software, while still a cottage industry of individual developers, early customers of Market Technologies became trading software developers themselves and created their own software, incorporating strategy back-testing patterned after ProfitTaker.
Mendelsohn’s genius was about creating a new paradigm for traders in a world that would rapidly evolve, a world the same in that moment, but yet a world on the verge of unprecedented new possibilities. Like most forward thinkers who are doers, Mendelsohn acted in the moment of his time because he saw the possibilities. And, like most visionary entrepreneurs, he didn’t just stumble upon back-testing strategies with ProfitTaker. He worked through a process that had steps, a process that created other important pieces along the way that would add real value to the trading tool chests of traders around the world.
Those pieces include other significant contributions to the world of computerized technical analysis and more stages in the evolution of the trading-software industry. Many of those contributions were incorporated into ProfitTaker in 1983, including the capability to perform rollover testing on actual expiring futures contracts, testing for lock-limit conditions that would prohibit a trade from being taken, forecasting closing prices a day in advance so that traders could execute trades just prior to the close rather than having to wait until the next morning’s open, quantifying the impact of execution timing on trading system performance, and displaying comprehensive history tester performance results.
Below are reproductions of handwritten notes that were used in the development process. The first two pages show Mendelsohn’s hand-written notes on how to program software to test actual futures contracts with rollovers, circa 1980 – 1981.
The next three figures are hand-written notes on the design, layout and content of various reports to include in a history tester, circa 1980 – 1981.
Again, as it is with most proactive visionaries, the technological limitations of his time did not impede his forward movement. Hardware and software were evolving and as they did, Mendelsohn was right there and aware enough to take advantage of Moore’s Law, the technological maxim that predicts processor speeds, or overall processing power for computers, will double every two years.
In the mid-to-late 1980s, as the trading-software industry matured, what would soon be referred to as the global economy also began to take shape.
In those early days of the PC genesis and trading-software development, Mendelsohn anticipated another aspect of the burgeoning technology boom. His vision now included an emerging global economy driven by advancements in global telecommunications including the then yet-to-be-understood Internet technology of the 1980s. This evolutionary step would open the door to high-speed, global-data transmission and globally interconnected economies and financial markets, which in turn would necessitate a new way to analyze markets – intermarket analysis, a revolutionary new take on market analysis.
To Mendelsohn, it no longer made sense to look at a single market in isolation, since in the rapidly evolving financial world, one market would influence another instantaneously, and that market in turn would influence yet another in that moment, and so on. It was no longer productive to calculate and chart linear ratios or differences in the price of just two markets.
In this light, he shifted his research efforts away from the single-market analysis approach that had been the mainstay of technical analysis for the past century and turned it toward intermarket analysis.
Mendelsohn’s research over the next few years proved effective in addressing the globalization of the markets and the need to employ intermarket analysis. In 1991, Market Technologies released its second-generation, intermarket analysis software, VantagePoint Intermarket Analysis Software. This software, unlike its less robust predecessor, applied the nonlinear, pattern-recognition and forecasting capabilities of neural networks to intermarket analysis, marking yet another significant step in the evolution of PC-based technical analysis.
Mendelsohn’s introduction of VantagePoint signaled a leapfrog evolutionary moment in the trading world. VantagePoint demonstrated that software could take advantage of the interconnection between global events and their effects on markets and how those ripples would affect technical analysis.
His approach to intermarket analysis gave him the ability to produce highly accurate, short-term forecasts of market direction for each target market under study, based upon both its own behavior and that of other related markets found to have the greatest impact on each target market.
Recognizing his pioneering work on intermarket analysis, the financial press asked him to present his ideas about the potential risks of globalization and possible adverse effects on the financial markets under strained global economic conditions, in numerous editorial articles.
His editorials in the Journal of Commerce in February, 1990 entitled “Build a Global Safety Net”(reproduced below) and in Futures in April, 1990 entitled “24-hour trading: Let’s do it right” were prescient in identifying a number of systemic risks and proposing possible solutions that regulators, exchanges, clearing houses, and central banks could implement to avoid a future global-financial meltdown.
In two editorial pieces for Technically Speaking, the Market Technicians Association newsletter, (“It’s Time to Rethink the Role of Technical Analyst” in September, 1991 and “Broadening the Scope of Technical Analysis: The Importance of an Intermarket Perspective” in March, 2001), Mendelsohn called for a broadened definition of technical analysis to include intermarket approaches that could identify and quantify the effects of related global markets on each market traded. The first of these editorials is reprinted below. The second is included elsewhere in this issue.
In the 23 years since the first release of VantagePoint, Mendelsohn and his research team at Market Technologies have continued to develop and perfect its proprietary mathematical processes and algorithms that now apply intermarket analysis to hundreds of global markets each day. These include commodities, ETFs, stocks, Treasuries, indices, currencies, and metals.
In 2013, the United States Patent and Trademark Office recognized Mendelsohn’s novel work, granting him two patents for his invention of technologies that combine intermarket analysis with neural networks to create leading technical indicators which forecast global markets (with an accuracy rate above 80%). His work goes on.
More recently, over the past several years, Market Technologies’ R&D team has been developing its next generation trading software platform, TradeShark. Currently available on a limited basis to select VantagePoint traders who are power-users, TradeShark applies Mendelsohn’s patented algorithms and processes that integrate global intermarket analysis with trend forecasting.
Throughout this evolution in technical analysis, Mendelsohn has succeeded at tailoring his unique analytic methodologies to meet the challenges of the financial markets of the 21st century. In today’s global era, traders must look beyond singlemarket analysis and trend following or risk extinction.
One man, one moment, sometimes that’s all it takes to spark massive transformation, and, sometimes, that one man in that one moment can disrupt the status quo. This is what Mendelsohn has done over and over again for the last forty years. He catalyzed the evolution of the trading software industry, an industry so critical today that no one would trade without utilizing analytical trading software. Neither would he or she look at any market in isolation and make trading decisions without at least paying attention to what’s happening in closely related markets.
His influence on the financial world has been featured in articles in Barron’s, Futures, Technical Analysis of Stocks & Commodities, Investor’s Business Daily, the Wall Street Journal, Technically Speaking, and on CNN, Bloomberg Television, and CNBC. He has written two books on this subject, collaborated on more than half a dozen books on technical analysis, and has published dozens of articles and editorials on technical analysis and the effects of globalization on the financial markets.
Mendelsohn, a Market Technicians Association member since 1988, introduced so many mutations into the technical analysis, trading-software industry that it is fair to say he is not only a trading software pioneer, but, more impressively, has remained a driving force in this arena for four decades. His innovations and achievements in technical analysis and prodigious contributions to the evolution of computerized technical analysis continue today.
Now in his late sixties, Louis Mendelsohn, married 38 years, with three grown sons and four grandchildren, is still active as the CEO of Market Technologies. Although his firm’s day-to-day operations are overseen by other executives (including his oldest son, Lane), he still provides his visionary guidance to help create the next generation of trading software, software relying on apps in the cloud or next-generation computers perhaps, or on something as of yet unseen to most people, save for people such as Louis Mendelsohn who will see it and then help foster the evolution process.
Evolution is what happens when an intelligent, motivated, and analytical person discovers his true passion early in life and then devotes the rest of it to pursuing his dream and staying at the forefront of innovations in that field.
Thankfully, Mendelsohn (with his wife, Illyce’s, encouragement and support) made the decision to leave the world of hospital administration to devote all of his energies and efforts to technical analysis and trading software development – at a time when very few traders even owned a personal computer or would have known what to do with it. Hospital administration’s loss is clearly a big win for technical analysis and traders all over the world.
