#看懂K线 K line charts are composed of individual "candles". Each K line contains four key price information: opening price, closing price, highest price, and lowest price.

Body part: Represents the range between the opening price and the closing price. If the closing price is higher than the opening price, the body is usually green or white (bullish); otherwise, it is red or black (bearish).

Shadow part: The upper shadow represents the difference between the highest price and the closing price (or opening price), while the lower shadow represents the difference between the lowest price and the opening price (or closing price).
