The so-called trading volume refers to the volume of transactions between buyers and sellers within a certain trading time. At present, the trading volume can best reflect the supply and demand relationship of the stock market.
Generally speaking, when the stock price or index is at a low level, the increase in trading volume will make supply less than demand, causing the rise of the stock price or index. When the stock price or is at a high level, the reduction of trading volume will lead to oversupply and the decline of stock price or index.
成交量的计算单位为“手”1手=100股。成交量可以分为分时成交量、日成交量、周成交量、月成交量、和年成交量。从形态上来说，成交量又可分为逐渐放量、逐渐缩量、快速放大量、快速出小量和量平。
High volume refers to the active market transactions, which mostly occur at the turning point of individual stocks or indexes. At this time, some people are determined to bet against the future market and sell, while others are determined to bet on the future market and buy. At this time, a relatively large trading volume will be formed.
Shrinkage means that the market transactions are relatively light, and most investors agree with the trend of the later period. There are few investors who buy or sell, which is reflected in the volume of transactions.
If there is a bottom volume increase, it is a reference buy, and if there is a top volume decrease, it is a reference sell signal.
The average volume line is a technical indicator that reflects the average trading situation of the market in a certain period, that is, the trading trend. The average line parameters are set to 5 days and 10 days respectively. The application of the mean line has the following two points.
1. In the early days of the rising market, the average volume line continuously hit new highs with the stock price, indicating the process of gathering market popularity. This is a reference buying signal. When the market comes to an end, although the stock price has reached a new high, the average volume line has been weak, forming a separation of price and volume. At this time, the market's willingness to follow the peak has changed, indicating that the stock price is close to the peak area, which is a reference selling signal.
2. At the beginning of the decline, the average volume line generally continues to fall with the stock price, indicating that the market is weak and weak. This is a reference selling signal. When the market is near the end, the stock price continues to fall to new lows, and the average volume line is mostly flat, which is a reference buying signal.
