Have you tried contacting them?
Andy Kershner is a former ProTrader owner and a former chairman of Zone Trading Partners, LLC. Both firms were located in Austin.
I heard something scandalous occured with his partners at Zone Trading and it closed. Kershner later started up again as Kershner Trading Group. Sorry, I don't have any info on my computer anymore.

Here is a quote that I have of something he said to a reporter:
"Houston-based stock trader Andy Kershner sees the changes. Six years ago, Kershner was a day trader betting his own money on 20- to 30-point swings in individual stocks. In March 2000, he made a big bet that technology stocks were about to fall, but did it a day too early and lost several hundred thousand dollars. Kershner, chairman and chief executive of Kershner Trading Group LLC, now finances and oversees 90 traders who use computers to make enormous bets on far smaller stock movements, generally one to three points, he said.
"Back then, almost everybody traded manually, and they were scrambling and yelling on the phone," he said. "Now you're pushing buttons. You can automate all or part of your trading strategy, and if you don't, you're going to get crushed."
The long boom leading up to the 2000 peak made trading seem easy, Kershner said. "Then, you didn't have to be in the right spot to succeed because the market covered up your mistakes. You just held onto it until it came back," he said.
Today, "there's not the same euphoria.""
