Volume (VOL) refers to the number of shares traded in a time unit, which is represented by a strip entity. Can be drawn in time-sharing chart and K-line chart. If it is the positive line in the K-line diagram, the entity is painted red, otherwise it is painted cyan or green. Volume is one of the most important factors to judge the market. Note: 1. The movement of stock market funds is the essence of stock price changes, and the analysis of trading volume is extremely important. The above application rules are only brief analysis methods, focusing on the analysis skills of reference volume-price relationship. 2. At present, the trading revealed by stock software is real-time trading. After the transaction, it is included in the transaction volume, and it cannot be included in the transaction volume without the transaction. So the sum of buying and selling has nothing to do with the volume. But the sum of the outer disk and the inner disk disclosed in the stock software is indeed the volume. 3. The price rises with the increase of trading volume, which is a normal feature of the market. The growth of this volume-price relationship indicates that the stock price will continue to rise. 4. The stock price fell below the stock price pattern, trend line and moving average. At the same time, a large volume is a signal that the stock price will fall deeply, emphasizing the reversal of the trend. 5. The stock price rises gradually with the increasing trading volume, and the gradual trend suddenly becomes an explosive market with vertical rise. The trading volume soared and the stock price soared. Then, the trading volume shrank sharply and the stock price fell sharply, indicating that the rally has come to an end and there may be a turnaround. 6. The volume is moderate. After the continuous downturn in the previous period, the volume of individual stocks showed a continuous moderate volume pattern, which generally proved that there was strong capital intervention. However, this does not mean that investors can intervene immediately. After the right amount of stocks appear at the bottom, the stock price will rise with the volume, and the stock price will be adjusted appropriately when the volume shrinks. When it lasts for a period of time, the rise of the stock price will gradually accelerate. 7. A huge amount of sudden release. There may be many situations. If the stock price rises after a long period of time, it usually means that the differences between long and short positions have increased, and the powerful funds have begun to be laid out, so it will be difficult for the market to continue to rise. However, the huge amount after the deep fall is generally the last concentrated release of empty power, and the possibility of further deep fall of future generations is very small, and the time for rebound or reversal is close at hand. If the stock market falls as a whole, individual stocks will increase against the trend, which will have a very eye-catching effect when the market is empty. Such stocks often don't last long, and then they accelerate their decline. 8. The trading volume is regular. When the volume forms an arc bottom and the stock price also forms an arc bottom, it often indicates that the stock market will have a greater chance of rising.
