The first type: the number of transactions increases, the number of positions increases, and the price rises. The combination points out that the transaction is lively, and the buyer's (multi-party) power is greater than the seller's (empty) power. Although long and short positions are increasing, new buyers are actively adding a lot of positions, chasing up and down, which shows that bulls have a higher view on the upside of the market outlook. This combination relationship has a strong upward momentum, and prices may continue to rise in the short term.

The second type: the number of transactions is reduced, the positions are reduced, and the prices are rising. This points out that the long and short wait-and-see atmosphere is strong, reducing transactions, lightening positions and raising prices. It is clear that short sellers throw in the towel and start to take the initiative to cover positions (that is, buy hedging) to push up prices, which leads to price increases in the process of lightening positions. However, the off-site bulls did not enter the market, and the short-term price rose, but it is likely to be adjusted back soon.

The third type: the number of transactions increases, the positions decrease and the prices rise. This combination shows that the empty side has taken the initiative to close the position. If it appears at the bottom, it shows that the price has risen slightly, because the price has fallen to the bottom, and the empty side has a good mentality, while many parties are worried and will not pull up immediately. However, if it appears at the top, bears are eager to close their positions and "flee for their lives" and chase the price level, while bulls only passively close their positions at high positions and do not actively suppress their forces, thus showing the characteristics of a sharp rise in prices. At this time, it is clear that both short sellers and long sellers are closing their positions in large quantities, and prices will fall.

The fourth type: the number of transactions increases, positions increase and prices fall. This indicates that the average long and short positions have increased, but the short positions have increased the active positions and sold at the chasing price. The reason why the price chasers dare to chase after the sale is because they judge that there is still a lot of room for price decline. However, bulls are unwilling to admit defeat, passive positions increase at low points, and prices may fall in the short term. However, if this portfolio is oversold and seriously deviates from the average price in the short term, it will lead to short-term speculative traders and new multi-party intervention. In addition, some old empty cash will increase in price, and V-shaped reversal is more likely.

The fifth type: the number of transactions is reduced, the position is reduced, and the price is falling. This combination shows that long and short positions reduce trading and tend to wait and see, but long positions are actively closing positions. The decrease in the number of transactions shows that the bulls are relatively rational, not eager to sell, but seeking the ideal price, so the price decline is gentle, but it will continue for some time.

Sixth: the number of transactions increased, positions decreased and prices fell. This combination shows that both long and short sides have trading intentions, but short positions are unwilling to continue to add positions, while lightening positions and falling prices indicate that long positions are eager to close positions and chase prices to sell contracts. The chasing power mainly comes from doing more stop-loss power. Therefore, after the price drops sharply, once the positions begin to increase, it means that new bulls begin to intervene, and those who feel that they are wrong re-enter the market, and the price may rebound strongly.
