影线是什么？

中文版：

影线，又称为影价，是股票K线图中的一个重要元素。它代表了某一交易日中股票价格的最高点和最低点，但并未被实际交易价格触及。影线的上下两端分别代表当日股票价格的最高价和最低价，而影线的实体部分则表示了当天的开盘价和收盘价。

影线的长短反映了当日股价波动的范围，即多空双方的较量程度。影线越长，说明股价在当日内的波动幅度越大，多空双方的力量对比越激烈。反之，影线越短，则表明股价波动较小，多空双方的力量对比相对平稳。

影线的形态也是投资者分析市场走势的重要参考。例如，上影线较长可能意味着股价在上涨过程中遭遇了压力，下影线较长则可能表示股价在下跌过程中得到了支撑。通过对影线的观察和解读，投资者可以更加深入地了解市场趋势，从而作出更准确的投资决策。

What are Shadow Lines?

Shadow lines, also known as shadow prices, are an essential element in stock K-line charts. They represent the highest and lowest prices of a stock during a trading session, but are not actually touched by the trading prices. The upper and lower ends of the shadow line represent the highest and lowest prices of the stock for that day, while the body of the shadow line indicates the opening and closing prices for the day.

The length of the shadow line reflects the range of price fluctuations for the stock on that day, indicating the degree of competition between buyers and sellers. A longer shadow line suggests a greater fluctuation in stock prices during the day, indicating a more intense battle between bulls and bears. Conversely, a shorter shadow line indicates smaller price fluctuations and a relatively stable balance of power between buyers and sellers.

The shape of the shadow line is also an important reference for investors analyzing market trends. For example, a long upper shadow line may indicate that the stock encountered resistance during its upward movement, while a long lower shadow line may suggest that the stock found support during its downward movement. By observing and interpreting shadow lines, investors can gain a deeper understanding of market trends and make more accurate investment decisions.
