1, BOLL indicators of the principle of
BOLL indicators of the U.S. stock market analyst John �Brin in accordance with the standard deviation of statistical theory devised a very simple and practical indicators of technical analysis. Generally speaking, the stock price movement is always around a central value (such as moving average, the cost of line, etc.) within a certain range changes Bollinger Bands Indicator is based on the above conditions, the introduction of the "price channel" of the the concept that the price of its channel width as the size of stock price volatility changes, and the stock channel but also has variability, as it will automatically adjust to changes in stock price. It is because of its flexibility, intuitive nature of the characteristics and trends, BOLL indicators of investors gradually become widely popular applications on the market index.
Among the many technical analysis indicators, BOLL indicators of belonging to a class of more specific targets. The vast majority of technical analysis indicators are constructed by the number of ways, and they themselves do not rely on trend analysis and morphological analysis, BOLL indicators are price patterns and trends are inextricably linked.
BOLL indicators of the "price channel" concept is the price trends of the theory of visual manifestations. BOLL is the use of "price channel" to show a variety of stock price, when the volatility is small, in the consolidation, the stock price will narrow channels, which may indicate the volatility of stock prices at a temporary period of calm; when the stock price volatility beyond the narrow The price channel on the tracks, indicating that the abnormal stock price volatility is about to begin intense upward; when the stock price volatility beyond the narrow channel under the tracks also indicates that the abnormal stock price volatility will begin intense downward.
Investors often encounter two of the most common trading traps, one trap to buy low, investors, after buying the so-called low, stock prices continued to fall but not only has not stabilized; 2 is to sell high-trap, the stock in so-called high - point of sale, the shares are way up. Bollinger Bands in particular the use of Einstein's theory of relativity, that all interactions between all kinds of markets, the market and the market between the various changes are relative and absolute nature does not exist, the price is relative high and low the stock in the trajectory above or below rail line reflects only the stock price is relatively high or low, investors have to make investment judgments before the comprehensive reference of other technical indicators, including the price of the amount of co-ordination of psychological type indicators, analog-type indicators the market linkages between data. In short, BOLL indicators of the price channel to predict the future trend of Quotes plays an important reference role, it is also characteristic of Bollinger Bands indicator analytical tools.
2, BOLL indicators of the calculation of
Of all the indicators for the calculation, BOLL index is calculated by one of the most complex, which introduced the concept of standard deviation in statistics, related to the rail line (MB), on the rail line (UP) and the next rail line ( DN) calculations. In addition, the calculation of other indicators, like the calculation result of the selection cycle, the different, BOLL indicators, including Japan BOLL indicators weeks BOLL indicators, month BOLL target year BOLL indicators as well as minutes BOLL indicators of various types. Frequently used is the day the stock market judged BOLL indicators and weeks BOLL indicators. Although the calculation of the value of their different, but the basic method of calculating the same.
Japan-BOLL indicators of the calculation, for example, which is calculated as follows:
1, Japan BOLL indicators of the formula
The rail line = N-day moving average line
On the rail line = line of the track twice the standard deviation of +
Under the rail line = line in the track - twice the standard deviation of
2, Japan BOLL indicators of the calculation process
(1) The calculation of MA
MA = N days, the closing price of the sum of ÷ N
(2) Calculate the standard deviation of MD
MD = square root of N-day (C-MA) of the two sides divided by N
(3) Calculations MB, UP, DN Line
MB = (N-1) Day MA
UP = MB +2 × MD
DN = MB-2 × MD
In the stock market analysis software, BOLL indicators of the total from the four lines, namely, the rail line on the UP, the rail line MB, under the rail line DN and price line. In which the rail line to connect UP is a UP value, with a yellow line represents; the rail line MB is the MB value connection, with a white line represents; the next rail line DN is the DN value of the connection, with purple line represents; the price line is based on the U.S. line that the color is light blue. And other technical indicators, as in actual combat, investors do not need to BOLL indicators of the calculation, mainly to understand BOLL calculation methods and processes in order to more in-depth grasp of the substance of BOLL indicators, in order to lay the foundation for the use of indicators.
