Average price mainly includes "arithmetic average price" and "weighted average price". The calculation method of "weighted average price" of silver T+D is as follows:
Let's assume a simple situation: silver trading * * * has five price points: 3 150(80 lots), 3 155(5 lots), 3 160(5 lots), 3 165(5 lots). Then the arithmetic average price is the sum of these five prices and then divided by five, that is, (3150+3160+3165+3170)/5 = 3/kloc-. Because this interval accounts for 85% of the trading volume of the day, when calculating the arithmetic average price, people comprehensively consider the calculation of the average price according to the number of times each value appears (mathematically called frequency). We consider 65,438+000 lots, so there are actually 80 lots of 365,438+050, 5 lots of 365,438+055, 5 lots of 365,438+060 ... Therefore, in order to fully reflect the real situation of the quotation, we must consider the frequency of each price, which is called "weighting". So we calculate the average price of this day as follows: (3150 * 80+3155 * 5+3160 * 5+3165 * 5+3170 * 5)/
