In futures, if there is a big drop, why do positions and trading volume decrease? Doesn't it mean that the decrease in trading volume and positions during the decline indicates that the decline has weakened? However, I saw that when many varieties fell sharply, the volume of transactions and positions decreased at the same time, but there was no sign of weakening. Are the following laws correct?

1: The increase in trading volume and positions and the rise in prices indicate that prices may continue to rise.

2. The decrease in trading volume and positions and the increase in prices indicate that prices will rise in the short term and will soon fall back.

3. The increase in trading volume, the decrease in positions and the increase in prices indicate that prices will fall immediately.

4. Volume and positions increase, prices fall, and prices may fall in the short term.

5. Trading volume and positions decrease, prices fall, and prices will continue to fall in the short term.

6. As the turnover increases, the positions and prices fall, and the prices may rise.
