While this book has focused on US regulation of derivatives (with an emphasis on the impact that AI systems and related technologies have had on these markets), people and firms trade futures and derivatives – often with the aid of computers – not just in the United States, but throughout the world. Algo bots are effectively borderless, and not just because they don’t have “bodies” in the sense that humans do, but because advances in AI systems and related technologies are not restricted to the United States, and because the business entities that use algo bots to trade can easily “locate” themselves at various points across the globe for tax, regulatory, or other purposes. This book would be far longer than it already is if I detailed how every nation regulated algorithmic trading of derivatives.
