From an economic point of view, open higher and go higher. In the stock market, bonds, foreign exchange, gold, futures and other capital markets, the opening price of the day's trading was higher than yesterday's closing price, and then it went up with time. This trend is often referred to as "opening higher and moving higher".

Low opening and low walking is a stock market term and a form of K-line trend. Simply put: the opening price is lower than yesterday's closing price, and then it begins to fall. The closing price is also lower than yesterday's closing price. K-line consists of opening price, closing price, highest price and lowest price. The opening price below the closing price is called the positive line, and vice versa. With the transaction time as the abscissa and the price as the ordinate, the daily K-line is drawn continuously to form a K-line chart.
