For the mainland stock market, there is no difference. Many softwares are basically the same. Four hours is actually a day's business.

But for domestic stock index futures and Hong Kong stocks, this situation has changed. Because the transaction time is longer than 4 hours.

Investment has certain risks, so you need to be more cautious when entering the market. If the market is open 22 hours like foreign markets, it is estimated that many people can't stand it, and they can't stand it in their hearts. At that time, the hospital may have been full. Because people who stock now tend to be middle-aged and elderly, they can't stand the toss. Four hours of trading time can also effectively control risks to some extent. The previous fuse mechanism is also to control risks.

The reduction of trading time, in addition to controlling risks, also hopes that retail investors can have more free time to resume trading, study after-hours stocks, reduce trading time, and prevent investment friends from worrying about stock trading all day at work.
