"Lock positions" means buying some chips for the main players or bookmakers, and then holding them to reduce the short-selling pressure of the main players or bookmakers when they raise the stock price. When they quit at a certain time, they can usually guarantee profits. Locking positions is a good thing for the rise of stock prices. First of all, if someone locks positions for the main force, it will help the main force to control the chips, and the rate of raising funds will increase. The number of stocks circulating outside will decrease, and it will naturally be easier to raise prices. In fact, due to the increase in the rate of raising funds, the main force can also reduce the number and intensity of dish washing, and the speed of price increase will be accelerated, which can reach the target price of the main force in a short time. However, it will take a long time for such stocks to be shipped in the main force, and it will be deceptive to retail investors. Especially at the end of the main force shipment, when they are pulled up again, the possibility of attracting more is greater. Therefore, for such stocks, it is necessary to be especially careful when they are sideways at a high position, especially for stocks that have been sideways for a long time. Don't buy such stocks in large quantities as refueling on the way.
