You can trade 24 hours a day. As long as you have a market trading account.

For example, the securities market account in China, and your accounts in the United States, Britain, Australia and other places.

If you talk too much, the trading time is different in different countries with different time differences. Then you want to open an account in an area with time difference, but it should be noted that some countries do not allow citizens of other countries to open accounts.
