When I got a chance to read that article completely, it is one of the best summaries of the issues that I have seen. About the only thing that is not covered is the complicated process of “desking,” through overseas associates in transactions. At the very least, overseas “brokers” or something resembling them, are used to put another layer away from US regulation. The ability to hide and move manipulation from one party to another makes it much more difficult for manipulation to be discovered, let alone stopped.
