That's because they are the financial channel of the portal website, not a professional financial information website, and it is normal to have a certain delay. Moreover, they may not mainly serve futures investors, but mainly serve securities investors, so they only provide stock index data after the stock opens. If you want to get to know the stock index at the opening, I suggest you take a look at He Xun. The futures section of com, a professional financial website, is also very concerned by people in the industry. If you want to know the dynamic information in time, I suggest you download a professional futures market software, you can download one from Wenhua Finance official website, and you can see the data of every second in the opening process.
