When the main force is shipping, their favorite thing is to have someone take over the orders. However, if the main force is accustomed to using shipping methods such as pulling up, shaking, and suppressing shipments, it is easy for smart investors to discover their shipping intentions, which can affect the main force's shipping. So, in the continuous practice of trading, the cunning main force explored a more covert way of selling, which is to use the limit up of stock prices to sell. This shipping method is more covert and easier to ship than other shipping methods. In many cases, the main force has successfully completed the shipping operation without any awareness from investors. Generally speaking, when a stock forms a limit up trend, it will inevitably attract a large number of investors to enter the market for operation, and the huge buying orders provide excellent selling opportunities for the main force to sell. At this point, the main force will intentionally put tens of thousands, hundreds of thousands, or even millions of their own buy orders on the buying list to attract followers. When the price pursuers buy in, they eat up some of it themselves, and finally seal the stock price at the limit up, and put a large or even huge amount of buying orders on the limit up board, attracting other investors to quickly place orders and buy. Based on the intraday situation, gradually withdraw your buy orders and place them at the bottom, and then gradually sell your stocks. Investors need to distinguish whether the main force is using the limit up board to sell, in addition to conducting detailed analysis of the stock's K-line chart and other situations, they must also conduct a detailed analysis of the volatility changes in the intraday chart. Because in many cases, investors can easily determine whether the main force is selling by conducting a detailed analysis of the fluctuations in the time-based chart. So, how do the main players use the limit up board to carry out shipment operations? Let's give an example below.

Huangtai Liquor Industry (000995): Huangtai Liquor Industry's stock price had already experienced a significant increase before shipment. On July 5, 2007, the stock price was suspended from trading for half an hour due to continuous increases. Trading began at 10:30 am, and the stock price opened flat and fell. After a brief decline, it quickly rose, and the volume increased sharply. The main players continuously used large orders in the three or four digits during trading to attract follow the trend and buy. 10: At 39 points, the stock price was locked at the daily limit up, while also attracting a large number of followers waiting in line to enter. A large number of buying orders provided great assistance to the main force's shipments, and the main force did not hesitate to "give" their chips to investors. Due to the relatively large number of chips in the hands of the main force, in order to attract popularity, the main force once again raised the stock price. When the market sentiment gathered to a certain extent again, the main force generously distributed the chips in their hands to actively buying investors. Figure 1

On July 6, 2007, the main force deliberately opened high and went high, giving investors a feeling that they couldn't buy it, in order to attract market sentiment. People usually have a mentality that the more things they cannot buy, the more precious they feel and the more they want to buy them. And the main force happens to utilize this mentality, as shown in Figure 2

On July 9th, it was closed at the daily limit up and has not been opened yet. The stock price has been locked at the daily limit up for two consecutive days, which has led to the peak of market buying enthusiasm. On July 10th, the main force once again opened with a limit up, but did not see any limit up opening until the morning closing. The trading volume during the day was only one or two digit orders, with few three digit sell orders. As can be seen from the intraday chart alone, the main force's chips were well locked in and firmly held, and they could still keep up. However, from the previous trend of the stock price, the main force has already made substantial profits. In this market trend, the main force has increased the stock price from the lowest 3 yuan to over 11 yuan, nearly four times. From the trend of stock prices from May 2007 to July 2007, it can be seen that the main force has been repeatedly pulling up, falling back, and selling. Therefore, we should be very careful and closely track the current limit up situation. Sure enough, a quarter of an hour before the closing of the afternoon, the purchase of over 90000 yuan in a single position was completely destroyed within two minutes. It can be said with certainty that the main force has been selling in large quantities and leaving immediately. Although the stock price ultimately hit the daily limit up, it was just another attempt by the main force to attract more investors, so there was no need to worry. Fig 3
