First in Engineering, then in Stock Trading,
TK Solver is ‘a Big Deal for Me’

Ron Isaacson has used TK Solver through most of a 30-year corporate and consultant engineering career, in projects ranging from perimeter security to automobile cruise controls to missile tracking. More recently, he’s been using TK to make money in the stock market, and done well enough at it that he declares , “TK Solver gives me that extra advantage I need to compete successfully in the difficult environment of active stock trading.”

“The biggest reason I use TK and like it is the way it keeps things organized in the sheets, the ease of the ability to change things, and getting immediate feedback when I have a syntax problem,” says Isaacson, of Mesa, Arizona. “It’s a friendly environment that allows me to keep things organized without a lot of effort, and to change things and see what the change does.

Stock trading is now full-time. Isaacson’s stock trading strategy, which he calls Market Veritas, uses TK Solver three ways:
He simulates stock-trading algorithms against historical data, from 15-20 years ago to the present. “TK is very friendly for this,” Isaacson says. “I can quickly change the algorithm, and try a lot of different things.”

He analyzes current stocks weekly, beginning with an always-changing list of about 3,000 stocks and ending with a list of stocks that he uses for trade decisions. He uses ASCII data from stock exchanges obtained via a subscription real-time data service.

He tracks real trade data in relation to what simulations would do with the same data. “It gives me a measure of my real trading versus what a simulated trade would be in an ideal world,” Isaacson says. “The actual trading is real-time, so sometimes seconds matter. I can identify areas in my system where my trading is not adequate. I continually monitor that, using TK Solver offline.”

His Market Veritas TK models have been “a continual work in progress since 1998,” Isaacson says. A complete Report Writer report, with functions, rules and variables, runs to 30 pages: 60 to 70 variables on the Variable Sheet, plus a large number of local variables, more than 50 lists, and about 50 functions. “I’m always trying to do new simulations and learn new things with and about the market,” he says.
Isaacson learned about TK in the early 1980’s, from an acquaintance at his alma mater, Arizona State University. At Motorola, where he worked from 1976 to 1998, Isaacson used TK to design a missile-tracking system. He started a consulting business, ISES LLC, after retiring from Motorola, and used TK extensively. He designed a perimeter surveillance radar system, using TK to simulate the algorithms used to identify an intruder—looking at such identifiers as the radar return pattern, frequency and range characteristics. He also used TK to design an automatic cruise control system for automobiles.
“It had to be able to track both vehicles and stationary objects,” Isaacson says. “I used TK to simulate the algorithm for the analysis and tracking system. You set the speed as with a conventional cruise control, but, depending on the obstacle, this device automatically reduces and maintains speed, or stops and restarts the vehicle.”
Ron Isaacson is plain-spoken in his ringing endorsement of TK Solver: “I’m doing this (case study) because TK Solver has been a big deal for me.”
