股票委比是什么？

中文版：

股票委比是股票市场中一个重要的技术指标，它反映了市场上买方和卖方之间的力量对比情况。简单来说，委比就是委买手数与委卖手数之差与它们之和的比值，用以衡量某一时段内买卖盘相对强度的指标。

委比的计算公式为：委比 = (委买手数 - 委卖手数) / (委买手数 + 委卖手数) × 100%。其中，委买手数是指当前买一到买五档位的委托买入的总手数，委卖手数则是指当前卖一到卖五档位的委托卖出的总手数。

委比值的正负和大小能够反映市场买卖力量的对比情况。当委比值为正时，表示买方力量较强，市场看涨情绪较高；当委比值为负时，表示卖方力量较强，市场看跌情绪较高。同时，委比值的绝对值越大，表示买卖双方力量差距越大，市场趋势越明显。

需要注意的是，委比只是一个指标，它并不能完全代表市场的趋势。投资者在分析股票时，需要结合其他技术指标和基本面信息，进行综合判断。

What Is Stock Commission Ratio?

The stock commission ratio is an important technical indicator in the stock market, reflecting the contrast of buying and selling forces between market participants. In simple terms, the commission ratio is the ratio of the difference between the number of buy orders and the number of sell orders to their sum, serving as a measure of the relative strength of buying and selling at a particular time.

The formula for calculating the commission ratio is: Commission Ratio = (Number of Buy Orders - Number of Sell Orders) / (Number of Buy Orders + Number of Sell Orders) × 100%. Among them, the number of buy orders refers to the total number of entrusted buy orders at the current buy one to buy five levels, while the number of sell orders refers to the total number of entrusted sell orders at the current sell one to sell five levels.

The positive or negative value and the magnitude of the commission ratio can reflect the contrast of buying and selling forces in the market. A positive commission ratio indicates stronger buying power and a bullish market sentiment. A negative commission ratio indicates stronger selling power and a bearish market sentiment. At the same time, the larger the absolute value of the commission ratio, the greater the gap between buying and selling forces, and the more obvious the market trend.

It's worth noting that the commission ratio is just one indicator and cannot fully represent the market trend. When analyzing stocks, investors need to combine other technical indicators and fundamental information for comprehensive judgment.
