Chip distribution is to add up the transaction amount of each price in history and judge the position cost of all tradable shares in the current market.

Of course, some historical transactions will be thrown out in the following trading days, which means that the previous transactions cannot be simply accumulated to the present, but must be attenuated to a certain extent. This attenuation ratio is also the daily turnover rate.

For example, for the 100000 plate, the average price of the day before yesterday was10 yuan, with a turnover of 2 million and a turnover rate of 20%; Yesterday, at the average price of 1 1 yuan, another 3 million yuan was sold, which is a turnover rate of 30%; What about the turnover of 2 million the day before yesterday? The cost analysis assumes that 1 1 yuan was used for 30% of the 2 million the day before yesterday, so the turnover of 10 yuan the day before yesterday is 200 * (1-30%) = 1.4 million; If the average price today is 12 yuan, it will sell another 4 million. Similarly, the current chip distribution is: 10 yuan, and the chip is 200 * (1-30%) * (1-40%) = 840000, 165438+.

So, he just set up a model to calculate, but he didn't really query the stock holding data of the exchange, which is not allowed to query, so the software provider can't get the corresponding information, and there is no information about the shareholding of the issuing company in the chip issuance as you said.
