However, it is almost impossible to know the position of the main force very accurately. We can only make a rough calculation in some way according to different stages and different times. Generally speaking, the main suction mode is divided into two stages: low suction and high suction. It is relatively easy to calculate the position in the initial stage, and it can be considered that the amount of funds raised accounts for about 15% to 30% of the total turnover. There are two forms in the pull-up stage, one is a sharp upward trend, which is the main method to actively collect chips. Generally, 50% of the total turnover is the main fund; One is a slow upward trend. At this time, the main force is often to ship while purchasing goods, constantly earning the difference and reducing costs. It can be considered that the amount of funds raised by the main force is about 25% to 35%. For some stocks with obvious absorption cycle, it is relatively simple to roughly calculate the main position, and the formula is: position = (absorption cycle? Average daily turnover during delivery? 2)- (delivery date? Average daily turnover during delivery? 2? 50%)。 As can be seen from the formula, the longer the delivery period, the larger the main position; The greater the daily turnover, the more the main force will absorb goods. In many cases, if the stock price is in the low-priced area, the transaction is quite active and the turnover rate is high, but the increase of the stock price is very small, which is generally the main fundraising behavior. Turnover rate = the sum of turnover during the period of picking up goods? Circulation disk? 100%。 As far as this factor is concerned, the greater the turnover rate of the stock price in the low-level region, the more abundant the main players will attract, which also reminds friends to focus on those stocks whose stock prices lag behind the volume changes in the low-level region, which will be a group of stocks with more opportunities in the next stage. Under normal circumstances, the rise of stock price is accompanied by the synchronous and effective amplification of trading volume, which is technically called price increase and volume increase, and is often caused by rushing out of profit-taking and cashing out. However, we can also see that the trading volume of some stocks gradually decreases with the rise of stock prices, which shows that the main positions are relatively large and there are not many floating yards outside. As long as the market does not turn and the trend does not break, such stocks can continue to hold positions and dance with Zhuang.
