实战移动平均线的买卖原理（The buying and selling principle of actual moving averages） The moving average (MA) is the Dow Jones average cost concept as the theoretical basis, using statistical principle, the moving average for a period of time, the stock price average value into a curve, used to display the historical volatility of stock price, stock price index analysis method and reflect the future development trend of the technology. It is the embodiment of the Dow theory. Moving average definition: average means the arithmetic average of the recent n day closing price; moving means that we always use the latest n day price data in our calculations. As a result, the average array (the closing price of the last n days) moves forward daily as the new trading day changes. When we calculate moving averages, we usually adopt the closing price of the nearest n days. We add the new closing price to the array day by day, while the last n+1 closing price is offset. Then, by dividing the new sum by N, you get the average of the new day (n days average). Calculation formula MA= (C1+C2+C3+... +Cn) /N C:, one day closing price, N: moving average cycle Moving averages are divided into short periods (e.g., 5 or 10 days), medium (such as 30 days) and long-term (e.g., 60 and 120) moving averages. According to the moving average algorithm is divided into arithmetic moving average, linear weighted moving average, stepped moving average, smoothed moving average etc., the most commonly used is described below the moving average arithmetic. The so-called moving averages, first of all, are arithmetic averages, such as 1 to 100 digits, with an average of 5.5, while moving means a change in the ten figures. If the first group is 1 to 10, the second group changes from 2 to 11, and the third group turns 3 to 12, then the average of the three groups varies. These sets of different averages are collectively called moving averages For example, the closing price of a share of ten consecutive trading days is
