This is very simple. The 5-day moving average crosses other moving averages upwards, and other moving averages cross downwards. Buy when it is in an upward trend and sell when it is in a downward trend. When the 5-day moving average is above other moving averages, it is a bull market with a strong trend and can be held; When the 5-day moving average is below other moving averages, it is a short market, and the trend is weak, so we should wait and see, or lighten up. Generally, stock prices fluctuate around the 5-day line. Whether it is rising or falling, as long as it deviates far from the 5-day line, there must be a process of regression and it will move closer to the 5-day line again. When the stock price falls below the 5-day line continuously, it means that it is now entering the downward channel and paying attention to risks. Standing on the 5-day line means that the stock is relatively strong now, but it needs to be analyzed and judged in combination with other indicators in specific operations. The 5-line operation method is only the simplest trading operation. Suitable for people who are not familiar with indicators.

MA5 in the stock is the 5-day moving average, which is an integral part of the K-line chart. The moving average is to average the stock prices for several days through statistical processing, and then connect them into a line to observe the stock price trend. The theoretical basis of EMA is Dow Jones' concept of "EMA leveling". There are usually 5 days, 10 days, 20 days, 30 days, 60 days, 120 days and other moving averages. Its purpose is to obtain the average cost of a certain period of time, and analyze the advantages and disadvantages of long and short positions in a certain period of time by using the moving curve of the average cost and the linear change of daily closing price, so as to judge the possible changes of stock price. Generally speaking, the current price is above the average price, indicating that the market demand is large and the market is promising; On the contrary, it shows that the buying pressure is high and the market is bearish. Let's take the 5-day moving average as an example to explain the origin of the moving average: take the arithmetic average of the five closing prices from 1 to the 5th and get the average price of 1; Calculate the arithmetic average of the five closing prices from the second day to the sixth day to get the second average price. By analogy, we can get a series of average prices, and connect these five-day average prices with curves to become a five-day moving average.

(1)5-day moving average (attack line): The rising stock price breaks through the attack line, and the rising trend of the attack line will lead to short-term bullish. Similarly, if the stock price falls below the 5-day moving average, it will be short-term bearish.

(2) 10 moving average (market line): when the trading line is getting higher and higher in the day, if the stock price reaches the top of the trading line, it means that the middle line of the band is rising, and vice versa.

(3)20-day moving average (auxiliary line): used to assist the 10 moving average, promote and correct the price operation intensity and trend angle, and stabilize the price trend operation direction. If there is a continuous upward attack on the auxiliary line in the session, once the price breaks through the auxiliary line, this means that the mid-line market of the band begins to see more and the reverse is empty.

(4)30-day moving average (lifeline): It is pointed out that the trend of mid-term stock price movement is its role, and the lifeline plays a strong pressure and support role. The same is true in the plate. If the lifeline trend is upward and the stock price breaks through or exceeds this line, it is bullish or bearish.

(5)60-day moving average (decision line): From here, we can see the mid-term reversal trend of the price, and guide the large-band level of the price to run in the predetermined trend. The basic main force attaches great importance to this moving average, which can play an indispensable role in the medium-term trend of stock prices.

(6) 120 moving average (trend line): The same is true, that is, it points out the long-term reversal trend of prices. If the price wants to run in a large band and level in the established trend, it must be guided or guided If the stock price is higher than the trend line, it will not change in a short time, and it usually takes ten days to reverse.

(7)250-day moving average (annual line): The layout of moving average is an important reference in long-term investment. It introduces the general situation and performance of the company.
