$BTC Entity Part: The candlestick body consists of the opening price and the closing price. If the closing price is higher than the opening price, the body is usually red (in customs such as the Chinese stock market), indicating an increase; if the closing price is lower than the opening price, the body is green (or black, etc.), indicating a decrease. The longer the body, the greater the price fluctuation.

• Upper and Lower Shadows: The upper shadow is the line segment extending from the highest price of the body to the highest price of the day, while the lower shadow is the line segment extending from the lowest price of the body to the lowest price of the day. They reflect the price fluctuation range during the day's trading.
