In this excerpt from Humanity in the Machine: What Comes after Greed? futurist Brian David Johnson describes his job as a “futurehunter” and his fascination with both algorithmic trading and high-frequency trading (HFT). Both methods use computer programs to automate and accelerate the execution of certain financial transactions. Yet heavy reliance on such technology in the finance world can be dangerous—the Flash Crash of 2010 cited by Johnson stands out as a prominent example.From Humanity in the Machine: What Comes after Greed?

As a futurist, a big part of my job is having a clear and actionable understanding of the future. But the other part of what I do is to travel the world talking to people about that future and looking for examples of how that future could be happening today. The science fiction writer William Gibson wrote, “The future is already here—it’s just not very evenly distributed.” This part of my work is futurehunting: searching for examples of the future happening today so that we can understand the human, cultural, social, and other impacts it could have.Because of futurehunting, I was fascinated with HFT and algorithmic trading. As we enter the age of Big Data and a time when we are living in a world surrounded by increasingly more intelligent computers, the sometimes murky and frantic world of HFT seems like a perfect futurehunting example of the future we are moving toward. HFT is an instance of the future playing itself out today. The Flash Crash of 2010 was the dark side of it.Now that we have an understanding for how the technology works, let’s dig into the world of algo trading. What makes it tick? What do the practitioners have to say about it, and what are its broader implications?When people talk about this world of financial machines, they often refer to something called the “black box.” This is a term used in high tech to describe a system that is a complete mystery. No one knows how it works except the people who designed it, and they won’t tell you about it. Black boxes worry people because the person who built and uses the black box has all the power.This mystery is especially dangerous when the black box starts to malfunction, like it did during the Flash Crash of 2010, and people get hurt.The rise and stall of algorithmic trading
“I want to talk to you about algorithmic trading,” I said into the phone. “I’m interested in high-frequency trading because it’s a kind of secret life of data.” “The peak of all this algo trading has happened,” Alan Wexelblat said quickly and with an easy assurance. “It’s over.”Alan is a designer. Starting in 2008 at Lime Brokerage, he designed interfaces for the software for high frequency trading. He not only had a front-row seat to the rise of algorithmic trading, he was in the game. Lime Brokerage is a sophisticated technological brokerage firm known for its high-performance, low-latency infrastructure (meaning they have really fast data connections) and market-neutral best execution delivery (meaning they are unbiased as to the markets they choose to trade and do business in). They don’t trade their own funds. For this reason they were touted as neutral because they don’t do in-house trading. Lime won the “Biggest Innovators on Wall St” award from Security Technology Monitor and “Most Cutting-Edge IT Initiative” award from American Financial Technology.Alan is a good guy. He’s married with two boys that are 13 and 10. Like most dads, he’s worried his sons are growing up too fast. Alan talks with the speed of an automatic weapon, and most of the time when he’s talking about algos, he’s deadly serious.“The first time I was really introduced to the world of algos and high-frequency trading was when I came to Lime in 2008 and was talking with Tony (Anthony Amicangioli) the CTO at the time. He used a white board to outline his vision for ‘Brokerage 2.0.’ His idea was to make an equities brokerage built from the ground up around the idea of HFT. He wanted automation to replace nearly everything that floor traders traditionally did. That was the fall of 2008.”“What did you think when you understood what he was talking about?” I asked. “What did it feel like to hear about HFT for the first time?”“To me the big idea, the real thing, never was HFT itself. I thought the really big idea was always about what you could do if you assumed that HFT was just table stakes…what if that was just the beginning.”The Flash Crash of 2010 may have brought algorithms and high frequency trading to the public’s attention, but it had caught the eye of a few reporters a little earlier. On Friday, July 24, 2009, nearly a year after Alan had seen it for the first time, high frequency trading hit the media mainstream.
