1. The daily K-line is drawn based on the four price levels formed in the one-day trend of the stock price (index): opening price, closing price, highest price, and lowest price. The rectangle in the middle adds a solid body, and the upper and lower lines are called leads!

When the closing price is higher than the opening price, the opening price is below and the closing price is above. The rectangular column between the two is drawn in red or hollow, which is called the Yang line; the highest upper shadow line is The point is the highest price, and the lowest point of the lower shadow is the lowest price.

When the closing price is lower than the opening price, the opening price is above and the closing price is below. The rectangular column between the two is drawn in black or solid, which is called the negative line. The highest upper shadow line is The point is the highest price, and the lowest point of the lower shadow is the lowest price.

2. If the opening price of the day is equal to the closing price and there is intraday shock, the K-line will form a cross star shape. If the highest price is equal to the closing price and the lowest price is equal to the opening price, there will be no cross star. The physical form of the lead, if the opening price is equal to the highest price, the daily limit is equal to the closing price, and the daily limit has been rising, it will be a horizontal line, and the lower limit will be the same. If there is a shock in the market, and finally it reaches the upper limit, it will be a T-shaped shape. If it falls to the lower limit, it will be an inverted T. If there are repetitions in the middle, it will form a hammer head shape! etc.
