The decline in trading volume means that the market is not good and should continue to fall.

The increase in shrinkage and the decrease in shrinkage indicate that the market may have an inflection point or weaken.

Of course, it's not just this meaning, it's not just a meaning, and it can't be simply understood as sucking or washing dishes. Its significance is different in different megatrends: it is the main means of delivery in the top and down trends, the main method of raising funds at the bottom, and the main dish washing skill in the pull-up.

"Volume enlargement and volume reduction" generally refers to the K-line combination with completely opposite trends on the K-line chart, which are two small trends. The turnover comes first and then shrinks. Volume is absolute and shrinkage is relative. Volume is the reference of contraction, and "contraction" is meaningful only in relative volume: it is the explanation of the purpose and significance of "volume" and the relationship between "volume" and "contraction". In the top and downtrend, the key to the "quantity" in the "shrinkage" is to look at the first volume, not only the current K-line combination, but also the overall trend: in the downtrend, the "quantity" is from large to small; In the process of rising, the "quantity" changes from small to large and moves regularly. For example, at the top, the main force is in the initial stage of shipment, and the absolute quantity is the largest; In the downward trend, the main force is shipment, and the absolute quantity is also large, but smaller than the top; After the decline, the absolute amount is much smaller. Therefore, the "quantity" in the "shrinkage" depends not only on its significance in the K-line combination but also on its significance in the megatrend, and the small trend should be subordinate to the megatrend.

For example, the top is the initial stage of the main high-level shipment. At the high, there are many K-bands, strong sports strength and the largest trading volume. Compared with the increase in volume, the volume is also large when it falls; In the rebound of the downward trend, when there are few bands, the motive force of the movement will be weaker and the transaction volume will be smaller than the top. Compared with the volume at the top, the volume at the time of shrinkage decline is not only smaller than that at the top, but also much smaller than that at the top.
