My professional story starts when I enlisted in the USAF to become a pilot during the Korean War. There, I was exposed to electronics and became absolutely fascinated with it. So, when I was discharged I changed college curriculums and got my BSEE and MSEE from the University of Missouri. I started as an antenna engineer, designing antennas for the B-52. I moved near Washington D.C., where I designed the Navy’s first shipborne antisubmarine Direction Finder. That antisubmarine technology is still used today in the LAMPS helicopters. In my spare time I studied for my Doctorate at George Washington University. I participated in the design of an Identification Friend or Foe (IFF) system that used the Fourier Transform of radar echoes from the fan blades of jet engines to uniquely identify various aircraft. My equipment was large, but the IFF system exists today on F-18s in the form of software. I designed a range of electronic filters and the data transmitter for SkyLab. As an entrepreneur I designed a residential fire alarm based on a semiconductor detection of hydrocarbons because I thought a radioactive ionization approach would never be approved. Boy, was I wrong on that one! So, I repurposed my semiconductor inventory to a sensitive gas leak detector that acted like a geiger counter. Industrial Research Magazine awarded the gas leak detector as one of the 100 best new products of 1976. I became Director of Engineering for Norlin Communications, developing precision surveillance receivers for Government Agencies and foreign governments. For example, these receivers were used to chase down pirates in the Strait of Malacca. In 1980 I joined Raytheon, and was the system engineer on a wide variety of Electronic Countermeasures Systems. I retired from Raytheon in 2005 as a Senior Engineering Fellow.
So, what does this have to do with trading? Not much, except I could apply my signal processing skills to the art of trading.
In 1978 Maximum Entropy was an advanced mathematical technique used in the seismic exploration for oil. The advantage of this approach was that only a short amount of data is required to attain a high resolution answer. I recognized this could be important for processing market data because the market cycles are efemerous, and using a short data sample could result in a more accurate measurement of the cycles in the market. Also, I recognized the changing cycles invalidated all the FFT data assumptions. I therefore adapted the Maximum Entropy to develop the MESA (Maximum Entropy Spectrum Analysis) product. In doing this, I scaled the result in terms of cycle period with which traders are familiar instead of the usual frequency axis. I developed MESA for my own use as a private trader, but word soon got out, and before I knew it I was a vendor. MESA is acknowledged to be the leading method of measuring the market spectrum. MESA was used not only as an indicator, but the measured dominant cycle was used to dynamically tune trading strategies such as EPOCH and SIERRA HOTEL.
The R-MESA program was written in 1992. It was an intraday program used for trading the S&P index. R-MESA was rated as one of the top 10 S&P trading systems continuously for over 10 years, as rated by Futures Truth.
My goal is to bring the science of engineering and Digital Signal Processing to the art of trading. Toward that end, I have written four books published by John Wiley & Sons and have written over 75 articles for Stocks & Commodities magazine. I introduce my latest research during my annual workshops held in October each year.
My Annual Workshop will be held October 10-14, 2022

If John Ehlers writes it, I read it. He’s that brilliant.
– larry williams
John is one of those rare breed of analysts who dives into the why and how of thing and not the often used superficial approach.
– Greg Morris
John Ehlers ranks with Art Merrill as the best quantitative analyst of the twentieth and probably the twenty-first century.
