Many parties actively build positions, indicating that the buying action is very active, that is, no matter what the price, everyone is buying more bullish. Then the premise is that someone wants to sell. Where does the selling order come from? There are two situations:

All in all, to put it simply, in the case mentioned by the landlord, selling orders mainly comes from two aspects, one is short positions and the other is long positions.

1 Some people are bearish. They may support the pressure zone, or be afraid of heights, or hear some unfavorable news, or even make mistakes in operation, and sell more and more when the price falls (trying to make it even if the price falls). Some people who have been short for a long time may think that this is a rebound, seize the high point of the rebound and sell it again, and keep selling under all kinds of strange ideas. Buy hard if you open more positions, and buy if you have a contract. In the quotation software, you can see the words "double opening" on the table on the right, indicating that both sides are opening positions, which illustrates this situation.

There are still some people who have been doing more before the volume, position and price rise, so when they see that the number of people in the market is increasing and the price is rising, they will make profits and close their positions when the market is the craziest (Buffett is like this). In the quotation software, you can also see the word "Duoduo" in the table on the right, that is, one multi-head contract is transferred and changed hands, and another multi-head holds it. This action is also for sale, and another long person will buy it.

That's it. I hope it can help you understand.
