When judging the main positions, it can be calculated by the statistics of internal and external disks of real-time transactions. The formula 1 is as follows: the main buying amount of the day = (outer disk × 1/2+ inner disk ×110)/2, and then accumulated for several days, the author's experience is at least 100%.
It usually takes 60- 120 trading days. Because the opening period of a band dealer is generally about 55 days. This formula requires investors to tirelessly analyze the target stock every day. After a long period of empirical statistics, the accuracy is extremely high, and the error rate is usually less than 10%.
For stocks with obvious bottom cycle, the author's experience is that the banker's position can be roughly estimated by multiplying the daily turnover in the bottom cycle by the bottom running time. Banker position = bottom cycle × active buying (ignoring retail buying). The longer the bottom cycle, the bigger the dealer's position; The larger the active buying volume, the more the dealers will absorb the goods.
Therefore, if investors observe the long-term sideways consolidation of stocks at the bottom, they will usually quietly absorb funds. Therefore, in order to reduce the buying cost, the main force will constantly clean short-term customers, which will be high-selling and low-sucking; But there is still a small amount of long-term funds involved. Therefore, during this period, the goods absorbed by the main force only reached about 1/3- 1/4 of the total turnover at most. Therefore, the active buying amount that ignores the buying amount of retail investors can be settled as total trading volume × 1/3 or total trading volume × 1/4. The second formula is as follows: banker's position = total trading volume × 1/3 or 1/4, and the lower amount can be confirmed cautiously.
Stocks with active low-level trading and high turnover rate, but with little increase in share price (the standard is that the increase in stages is less than 50%, preferably less than 30%), usually attract goods for the bookmakers. The greater the turnover rate here, the more fully the main force will attract funds, and investors can focus on stocks whose "price" temporarily lags behind "quantity".
The author's experience is that the turnover rate is based on 50%. Every time the stock price goes through 2, 3, 4 and other stages. The stock price trend will enter a new stage, which also indicates that the banker's position will change. The formula 3 for calculating the banker's position by using the turnover rate is: stock circulation × (the turnover rate of individual stocks in a certain period-the turnover rate of the market in the same period); When the calculation result is divided by 3, the practical significance of this formula lies in that the amount that the main capital exceeds the turnover rate of the large market (that is, the average purchase amount) is usually the intervention of foresight funds, which is generally applicable to the long-term decline of unpopular stocks. Therefore, once the main force continues to absorb unpopular stocks, we can relatively easily calculate the positions held by the main force.
