When were stocks powered by computer code first born? The recognized milestone points to 1976 that year, the New York Stock Exchange officially launched the Designated Order Turnaround system (DOT system). This system was the first to use computers to transmit trading instructions directly from brokers to exchange trading floors, becoming the prototype of code-based trading. Since then, futures, foreign exchange, and cryptocurrencies have adopted this method. Later, the idea that every user is an individual instance evolved into increasingly dense monitoring of public activities and accommodation, and even more frighteningly, monitoring of people s healthcare and organs.
