Abstract: I have invented a system which enables the cross-border trading and settlement of securities and financial instruments worldwide by linking markets and exchanges using a specifically devised computer network. My system frees the markets and exchanges of prevailing limitations imposed by the need to harmonize the automated systems, rules, procedures and practices of existing markets and exchanges to achieve this objective. At the same time, my system does not affect the sovereign status of any home market or exchange, leaving all its laws and mechanisms uncompromised. In all of its respects, my system is novel, unique, without particular precedent, and has long been desired. It will advance economic activity and make possible growth with profit in markets and exchanges worldwide.
