American futures open in China at night and have electronic versions in China during the day. Does the electronic version drop during the day and start to drop at night?
Unlike China, futures in the United States can't be opened at night, but they can be closed, so there are price changes at night (in the United States, it is the daytime you see), but at this time, the trading volume is small and the price changes are temporary, which can't explain the price trend of the next day. Of course, many times the trend of rising or falling at night continues.
