什么是量比？

量比是指股票交易所在时间点上的平均每笔成交量与过去五个交易日平均每笔成交量的比值。量比反映的是投资者在一定时间内的交易活跃度和市场情绪，是投资者进行短线交易的重要参考指标之一。

量比的大小可以反映市场的供求关系和投资者的交易意愿。如果量比数值较大，说明当前市场上交易量较过去五个交易日有所放大，市场活跃度提高，投资者交易意愿增强；如果量比数值较小，说明当前市场上交易量较过去五个交易日有所缩小，市场活跃度降低，投资者交易意愿减弱。

量比对于短线交易者具有重要的参考价值。在股价波动的过程中，量比的大小可以反映出市场主力资金的动向和投资者的交易情绪。通过观察量比的变化，交易者可以更好地把握市场机会和风险控制。

需要注意的是，量比是一个相对静态的指标，只能反映当前市场的交易情况，不能完全代表未来的市场趋势。因此，投资者在进行交易决策时，还需要结合其他技术指标和市场信息进行分析和判断。

总之，量比是股票交易中一个重要的参考指标，反映了市场的供求关系和投资者的交易意愿，对于短线交易者具有重要的参考价值。

What is volume ratio?

Volume ratio refers to the average volume of each transaction at the stock exchange trading venue at a given time point divided by the average volume of each transaction over the past five trading days. The volume ratio reflects the market activity and market sentiment of investors during a certain period of time and is an important reference indicator for investors to trade short-term.

The size of the volume ratio can reflect the supply and demand relationship in the market and investors' willingness to trade. If the volume ratio is high, it means that the current trading volume in the market is higher than the average trading volume over the past five trading days, market activity increases, and investors' trading willingness enhances. If the volume ratio is low, it means that the current trading volume in the market is lower than the average trading volume over the past five trading days, market activity decreases, and investors' trading willingness weakens.

The volume ratio has important reference value for short-term traders. In the process of stock price fluctuations, the size of the volume ratio can reflect the trend of market main funds and investors' trading sentiment. By observing the changes of the volume ratio, traders can better grasp market opportunities and risk control.

It should be noted that the volume ratio is a relatively static indicator that can only reflect the current market trading situation and cannot fully represent the future market trend. Therefore, investors need to combine other technical indicators and market information for analysis and judgment when making trading decisions.

In summary, volume ratio is an important reference index in stock trading, reflecting the supply and demand relationship in the market and investors' willingness to trade. It has important reference value for short-term traders.
