At no other point in recent memory has speed in trading been more at the forefront of public discussion.
The entire financial services community can thank noted author Michael Lewis for that. His "Flash Boys" book highlights the world of high-frequency trading and sets out a story line that has put computer-driven trading strategies under an intensely scrutinizing microscope.
Speed has created a world of "haves" and "have-nots" in the investing world. Markets have always rewarded those who could get a first-mover advantage, and beat others to money-making opportunities: In ancient times, it was how many months or years it would take you to source and ship products on long trade routes. Today, it's about how many microseconds it takes for one buy order to beat another buy order to the same supply of stock.
