Why is the futures trading in the United States still the same, and many countries use computers to match bids?
You want to ask why the United States is still using the old method? Hehe, there are long historical factors. The difference between computer and manpower is like the building and foundation you built. Labor is the foundation, and electronics is the high-rise building on the foundation. The foundation was first laid in America, and then there were tall buildings. That is, the combination of labor and electronics now, and most other countries are electronic. The advantage is high efficiency, but the disadvantage is too dependence. If there is a virus or something, it will collapse. The advantage of manpower is that some transactions, such as crashes, occur. In the trading hall, there is emotional communication between people. For the sake of the long-term stock market and one's human feelings, bears sometimes do not do so well. Let's be bulls, but in the case of no one meeting in electronic transactions, things are often not done well. Did you see him let the bull get away in the car accident? The American stock market survived, otherwise it would have closed long ago.
