Open position: refers to the ratio of the market value (amount) of money held by investors to the total investment. In the futures market, open position refers to the sum of positions bought (or sold) before open position, and generally refers to the sum of open contracts in the buying and selling directions, also known as order quantity, which is generally even. By analyzing the change of positions, we can analyze the size, change and renewal of long and short forces in the market, thus becoming one of the technical analysis indexes different from stock investment. In the analysis of futures graphic technology, it is very important to cooperate with each other in volume and position. A correct understanding of the relationship between trading volume and position change can help us grasp the combination of graphic K-line analysis more accurately and help us understand the market language more deeply.

The most common, accurate and effective method is to use the turnover rate to calculate the dealer's position.

The calculation formula of turnover rate is: turnover rate divided by the total number of outstanding shares multiplied by 100%, and the result is turnover rate. What we want to calculate is the total turnover rate from the time the dealer starts to build a position to the time when it starts to pull up. The weekly chart has the greatest reference significance.

When the moving average system of the weekly K-line chart is arranged in multiple positions, the parameters of the weekly moving average can be set to 5th,10th and 20th, which proves that the stock has banker's intervention. It is precisely because of the involvement of a large amount of money from the banker that the turnover of individual stocks will continue to increase at a low level, which is the characteristic of the banker's opening of positions. Due to the shortage of chips, the stock price is rising gradually, which makes the weekly K-line moving average system in a long position, and it can be preliminarily concluded that the banker has been found.

A banker, whether it is short-term, mid-line or long-term, must have at least 20% control, and only 20% of the stocks can be controlled, below 20%. Unless the market is excellent, it cannot be done. If it is controlled between 20% and 40%, the stock is the most active, but there are more hot money, less room for growth, and it is more difficult to pull up; If the trading volume is controlled between 40% and 60%, the stock will be more active and have more space, and this degree will reach relative control; If the control amount exceeds 60%, the activity is poor, but the space is huge, which is absolute control-the big black horse is mostly produced in this highly controlled stock.

Why is there such a rule? Because 20% of the circulation of a stock is generally locked, these are absolute long-term investors. Of the remaining 80% circulating chips, only 20% are the most active floating chips. If these 20% floating chips are collected, there will be few floating chips in the market. Therefore, it can generally control the market, and the last 60% is a relatively stable chip. If the banker absorbs another half, that is, 30%, then the banker's chips are 50%, plus 20% of long-term investors, which means that the banker controls 70% of the chips. In this way, the dealer can control the direction of the stock price. This is also the degree of control adopted by most gaming companies. If the dealer controls more than 60% of the market and only 20% floats outside, then the Zhuang family can control the stock price at will. Therefore, if investors want to follow Zhuang, it is best to follow Zhuang shares with positions exceeding 50%. Of course, the bigger the position, the better, because the increase is generally proportional to the position.

Generally speaking, when the stock price rises, the dealer accounts for about 30% of the trading volume, and when it falls, it is 20%. But when the stock price goes up, it goes up, and when it goes down, it shrinks. We can preliminarily assume that the volume/shrinkage =2/ 1, so in a period of time, the dealer's position will be (2 * 30%)-( 1 * 20%). However, this calculation is too complicated. We can make a rough calculation. During the period when the turnover rate is 200%, Zhuang Jia can absorb 40%, so the chips that can be absorbed when the turnover rate is 100% should be (40%)↓(200%)* 100% = 20%. We started from the week when the weekly KDJ index was at a low level and the weekly trading volume was moderately enlarged at a low level. Until the week you calculate, add up the weekly turnover to be the total weekly turnover, and then divide it by the circulation disk and multiply it by 100%, which is the total turnover rate. If the total turnover rate is 100% and the main position is 20%, if the turnover rate is 200%, the banker holds 40%, if the total turnover rate is 300%, the banker holds 60%, if the total turnover rate is 400% and the banker holds 80%, the turnover rate is 60% at a time.

Generally speaking, when the total turnover rate reaches 200%, the dealer will speed up the fund-raising and increase the position, because the low-priced chips are gone. This is a good opportunity for short-term intervention, and when the total turnover rate reaches 300%, the dealer has basically absorbed enough chips, and then the dealer will quickly pull up or forcibly wash the dishes. By calculating the total turnover rate in this way, we can roughly judge the degree of the main position and whether the position is completed. This can maximize profits and minimize time.
