Not all foreign transactions are computer matchmaking transactions. Think about it. The stock market has developed for hundreds of years. How many years has the computer been used? So there are non-electronic transactions in the United States and Britain, that is, transactions are conducted on exchanges. Just like on TV, buyers and sellers wear red vests and yellow vests to bid openly and trade with gestures, sounds and gestures. Of course, computers are also used, but they are recorded by computers after bidding, rather than directly producing data by computers. This is called public bidding. Maybe my language is not professional enough. You can look up "open tender" on Baidu Encyclopedia. The electronic disk is our stock market, and futures are all electronic disks. The red vest and yellow vest in exchange are of little use. Look at the computer over there without too much operation. The transaction is completely completed by the computer host. In the United States and Britain, it is generally an open outcry transaction during the day, and it is an electronic transaction at night because there are few people.

Over-the-counter trading refers to non-floor trading, and transactions that are not completed in the exchange during trading hours are called over-the-counter trading. It is not necessarily a spot transaction. There is another kind of transaction, just electronic transaction. Look at the beautiful soybeans in CBOT. They will move during the day. This is electronic trading, and it is also a long-short transaction between the two parties through the host of the exchange. In fact, their electronic disks are just like our domestic daytime transactions. It's just that the activity may not be as high as ours Another kind of disk is called artificial disk, which corresponds to electronic disk.

At night in our country and during the day in the United States, the transaction is quite active. This is an artificial market, that is, there are people in the exchange who are bidding openly.

Electronic disk and manual disk are two different trading methods according to different bidding methods.

According to different trading places, distinguish between on-site and off-site

There is no relationship between the two classification methods.
