Average cycle of the system there are many choices, from three days to a few hundred days, investors have used moving average line. But in the end should be done for a few days moving average line Quotes judged by reference to compare with the results, this issue has plagued the majority of investors. Because most investors tend to short-term speculation, therefore the average securities firms set up, usually short-term or short and medium term moving averages, such as 5, 10, 20 or 5, 10, 30, very rarely used to represent the short to medium The average length of three trends. In fact, the average selection should represent the short-and long three kinds of trends, rather than over-emphasis on a particular trend in the expense of other trends, this is unwise, therefore, should refer to the following trends:
î—?î—?short-term trends: usually refers to the one-month stock price volatility following the trend, because on the 5th line represents the average of a week fluctuations. 10, line represents the half-line. Therefore, we often they represent short-term trends, short-term moving average volatility of ups and downs are usually larger, too sensitive.
î—?î—?medium-term trend: this refers to more than one month, six months following the trend of stock price volatility. Common on the 20th line, 40-day line, 60-day line. This is because on the 20th line represents the trend of one-month stock price volatility. 40-day line represents the trend of the two-month stock price volatility. 60-day lines represent the three-month fluctuations in the trend, but also exactly a quarter, so called quarter-line, there are also investors use. The medium-term moving average trend is neither too sensitive, another aspect of calm, so the most frequently invest in people.
î—?î—?long-term trend: more than half a year refers to the volatility trend. Commonly used is the 120-day line and 240 on-line. 120 days line represents half of the fluctuations in direction, also known as half-line. 240-day moving average represents exactly one year fluctuations in direction, also known as year-line. Overall, the trend over the long-term average is not stable and flexible.
î—?î—?In order to simultaneously display these three trends and long-term, short-, medium-term average cost of the investing public, we should also choose these types of trends, but not because of personal habits or hobbies favoritism. Can not simultaneously observe several changes in the trend, it is not able to do analytical work.
î—?î—?Many investors set up some unusual moving average cycle, such as: 7, 9, 13, 27, etc. The purpose is to worry about making deceived line. This is completely unnecessary, in fact, as long as the short-term fluctuations, there is always the possibility of the main intentionally crossed. This is because the short-term moving average of the most easily manipulated, while the long-term trend is very difficult to deliberately crossed, if all investors are the reference period average 240-day moving average, even though the main aware of this, he can do cheat line? This is precisely the same time three trends should be considered the main reason. Therefore, we do not need to deliberately set the average number of cycles does not commonly used.
î—?î—?should be noted that in order to calculate the average closing price of the system point, because in the past, whether any of the technical indicators, including the k-line records, is completely manual records. So, to each stock's closing price of the record has already been very easy, to get the stock's daily average, there must be provided all the transaction records of transactions can be calculated. On the one hand calculations too large, on the other hand information on hard-won, while the closing price is more readily available, it will calculate the moving average closing price of the base line of the passage of time habit, it has been in use to this day. In fact the share price may represent the average cost of a day is certainly not the closing price, but the average day. The use of short-term moving average closing price, for example 5, moving average, on the average price from the real gap between the larger, so using this method of calculation of the average cycle, the shorter, the more we can not represent the average cost. Relatively speaking, the longer the cycle of the smaller this error, it represented the true meaning of the daily average price, rather than the closing price, this factor is to use moving average systems, an investor must pay attention to.
