The first floor of an office building, or a grassroots office. Not much different from other companies. There is a computer on the desk. In theory, the futures exchange does not allow staff to participate in trading, but the account is not its own name. The specific trading steps are no different from those of retail investors. The difference is that retail investors see the transaction price, while exchanges see the stop-loss price. This price doesn't make much sense even if it is shown to retail investors. If the margin of an account is found to be too low, it will be automatically closed by computer control. Punch in at work, Monday to Friday, 9 am to 3 pm. A floor is a large number of computer rooms, processing this transaction data. That's all. Most traders don't come to futures exchanges, and there are only four exchanges in China. When a trader opens an account in a futures company, he can directly participate in the trading of the exchange. Few people come to the exchange after having a computer.
