How the Speed of a Trade Got Nearly Down to the Speed of Light
The average person can enter a stock trade on their computer, hit refresh, and the trade is done. As fast as that seems, there are professional traders moving even faster, executing thousands of trades per second. Over the years, the need for speed got so intense that competing firms would aim to get their own systems closer and closer to the exchange's computers, so as to minimize the length of the wires and get their trades in even faster. How did this happen? And how does this change the nature of trading itself? On this episode, we speak with Donald Mackenzie, a professor of sociology at the University of Edinburgh in Scotland. Professor Mackenzie has been studying the intersection of finance and tech for a long time, and in 2021 wrote the book, Trading at the Speed of Light. We discuss the history of finance technology and look at where the technological arms race is going next.
