In the analysis of futures graphic technology, it is very important to cooperate with each other in volume and position. A correct understanding of the relationship between trading volume and position change can help us grasp the combination of graphic K-line analysis more accurately and help us understand the market language more deeply. The following analysis of trading volume and position matching four dynamic situations.

The trading volume of 1 increases gradually, and the positions also increase synchronously.

This kind of situation is the most common in the futures trend, which mostly occurs at the beginning of the unilateral market, and the price trend is in turmoil. The serious differences between the long and short sides on the market outlook have formed the competition for funds in the market, but the price has not yet formed a unified consolidation range, and the price fluctuates rapidly and frequently, which makes short-term investors have enough profit space. At this time, the expansion of trading volume is due to the active entry and exit of short-term funds, while the expansion of positions shows the accumulation of long and short energy. In this case, you can feel the change of the strength of the long and short forces from the disk, and at the same time, combined with the trend of the previous market, judge the changing direction of the market.

2. The trading volume gradually decreases and the positions gradually increase.

This situation is often a precursor to the coming of a big market. At this time, the forces of both long and short sides and the external factors of the market work together to make the market reach a balance in the dynamic. The decrease in transactions is due to the gradual balance of price fluctuation range, which makes short-term funds unprofitable. However, the increase in positions means that the differences between the long and short sides have increased and the financial confrontation has gradually escalated. Due to the unclear results of the differences, the long and short sides did not give way to each other and increased their positions one after another. Without breaking the deadlock first, the transaction gradually decreased, waiting for the final breakthrough. This situation is very fierce, and there are few false breakthroughs. Once it breaks out, there should be at least an intermediate market, and investors should do a good job in fund management.

3. The trading volume is gradually increasing, and the positions are gradually decreasing.

This situation generally occurs in the process of a market relay, and is accompanied by the phenomenon of killing more and more. Because the market is beneficial to one of the long and short sides, the other side has fled and their positions have gradually decreased. However, the rapid price movement provided a good opportunity for short-term speculation, so short-term funds actively intervened and the transaction did not decrease. Sometimes the increase of short-term positions masks the withdrawal of long-term funds, which leads to the trend of decreasing positions is not obvious. In this case, it may be accompanied by a mid-term rebound. Because of the violent rebound, it often gives people a feeling of turning around, but the original trend will continue.

4. The trading volume decreases gradually, and the positions decrease gradually.

This situation mostly occurs at the end of a wave of market, and the synchronous contraction of trading volume and positions proves that both long and short parties or one of them lose confidence in the market outlook and the funds are gradually withdrawing. If this situation continues to develop, it will provide favorable conditions for the intervention of new funds and become a precursor to change. As the volume of transactions and positions are relatively small, the market is easily influenced by external factors, and the price fluctuation is random, which will cause unnecessary losses to investors.

From the above situation, we can see that the volume of transactions is the basic driving force to promote market development, and the price changes tend to be active when the volume of transactions increases, and moderate when the volume of transactions decreases; Open position is the internal driving force of market development. Masukura is the beginning of a market and Masukura is the end of a market.

The combination of different changes in trading volume and positions combines a variety of changeable graphic forms, which in turn promotes the gradual change of prices.

In order to better apply this analysis method, we should pay attention to the following points:

1. The emergence of these situations is closely related to an independent and spontaneous market.

In the past two years, due to the gradual integration of the domestic market with the international market, the trend of individual futures products has gradually lost its independence, so the relationship between trading volume and positions in the application is not as obvious as that in the early market. However, after China's futures market is further opened and its independent trading system is gradually mature, the trading characteristics of the varieties themselves will become more obvious, and the relationship between trading volume and positions will become more and more operable.

2. This analysis is suitable for single variety analysis.

In a single variety, we can basically clearly see the combination change law of trading volume and position, but it is not suitable for the long-term segmentation chart of futures variety construction.

3. Varieties entering the delivery month.

Entering the delivery period, due to the closer relationship between trading varieties and spot prices, coupled with the constraints of relevant systems, futures varieties will go out of some extreme changes, which cannot be explained by the relationship between trading volume and positions.

4. Active locking of the main force.

This situation gradually disappeared in the gradual improvement of the market.

Although the above situation will limit the analysis methods of trading volume and positions, investors can create new analysis methods to interpret market language according to the actual situation after accurately understanding the basic analysis principles.
