High opening and high walking refers to the early trading behavior, and most of the relative futures are the price trend within 15 minutes of opening. If you only refer to the trend of one day, you should add "all day" in front, indicating that the trend of the whole day is high.

For example:

Open higher and go higher all day. When yesterday's closing price was 10, today's opening price is 15. If the all-day price does not fall below the opening price 15, it can be defined as high opening and high all day.

Open higher and go higher in early trading. When yesterday's closing price was 10, today's opening price is 15. After the opening, the price soared to 20 minutes, but it still did not break through today's opening price 15, so it opened higher and went higher in early trading.
