为什么补缺口？

中文版：

在股票市场中，“补缺口”是一种常见的现象，也是许多投资者关注的焦点。那么，为什么会出现补缺口的现象呢？

首先，从技术分析的角度来看，补缺口是由于股价在快速上涨或下跌后，由于多空双方的力量的变化，形成的价格跳空。当股价反向运动时，这些跳空的部分就会被填补，形成所谓的“补缺口”。

其次，补缺口也是市场心理的一种反映。当股价出现跳空时，市场中的一部分投资者会认为这是股价即将发生反转的信号，因此他们会在股价反向运动时迅速采取行动，从而加剧了补缺口的形成。

此外，补缺口还与市场的供求关系有关。当市场上的买方或卖方力量突然增强时，股价可能会出现跳空。随后，随着市场的供求关系的变化，这种跳空会被逐渐填补。

总的来说，补缺口是股票市场中一种重要的现象，它反映了市场的供求关系、投资者心理和技术分析等多个方面的因素。对于投资者来说，了解补缺口的原因和规律，有助于更好地把握市场趋势，制定投资策略。

Why Do Markets Fill Gaps?

In the stock market, the phenomenon of "filling gaps" is a common occurrence and a focal point for many investors. So, why does the phenomenon of gap filling arise?

Firstly, from a technical analysis perspective, gap filling occurs due to changes in the forces of bulls and bears resulting from rapid price movements up or down. When prices reverse, these gaps, formed by price jumps, tend to be closed, hence the term "filling the gap".

Secondly, gap filling is also a reflection of market psychology. When a gap appears in prices, some investors interpret it as a signal that prices are about to reverse. Consequently, they act quickly during the reversal, which intensifies the gap-filling process.

Moreover, gap filling is tied to the supply and demand relationship in the market. Sudden enhancements in buyer or seller strength can cause price jumps, creating gaps. Subsequently, these gaps are gradually closed as the supply-demand dynamics shift.

In summary, gap filling is an essential phenomenon in the stock market, reflecting various factors such as market supply and demand, investor psychology, and technical analysis. Understanding the reasons and patterns of gap filling can assist investors in better navigating market trends and formulating investment strategies.
