Short sellers want to suppress prices, but they can also close multiple positions. They sell and open positions when they open empty orders, and sell and close positions when they close multiple orders, which makes the price fall.

In order to raise the price, you can not only build more orders, but also close the empty orders. Similarly, opening more orders is just buying and opening positions, and closing positions is just buying and closing positions, all of which make prices rise.

If the bulls want the price to go up, they will open their positions desperately, and if you are short, they will close their positions. In short, the price will go up as much as you can buy. It's like there are more people buying things in our life. If things are scarce and expensive, prices will go up.

If the short seller wants the price to fall, he must open the position or close the position if you have a long position. The more you sell, the cheaper the less rare things are, and the price will naturally fall.

By the way, you are powerful enough to be the main force in the market, and your behavior will affect the market and achieve your goal.

If you don't even understand the four phrases of buy, sell, open and close, that is, buy, close, sell and close, then I'm talking in vain.
