Hello, for the above request, please refer to various financial market calendars. These calendars typically categorize data impact levels using different colors or markers, such as "high impact." For example, on platforms like ForexFactory, economic data with a red mark is considered high-impact. Similarly, on Jin10, economic data marked with three stars or more is considered significant.
However, it's important to note that there may be unforeseen major economic data or events, such as unexpected central bank announcements, official speeches, surprise economic reports, geopolitical issues, or other urgent incidents. Relevant authorities reserve the final decision on what qualifies as significant. Thank you.
