Detailed explanation of digital currency brining line

1. Bollinger band is a very practical technical index designed according to the principle of standard deviation in statistics. It is composed of three track lines. The upper and lower lines can be regarded as the pressure line and support line of the price respectively. Between the two lines is a price average line. Generally, the price line Travels in the belt interval composed of the upper and lower tracks, and the position of the track is adjusted automatically with the change of the price. When the wave band narrows, intense price fluctuations may occur immediately; If the high and low points cross the edge of the band and immediately return to the wave band, there will be a shift back. The indicators used in the digital money market and other financial markets are similar.

2. Taking the calculation of daily boll index as an example, the calculation method is as follows:
calculation formula of daily boll index:
middle trajectory = n-day moving average, on-line trajectory = middle trajectory + twice standard deviation, lower trajectory = middle trajectory - twice standard deviation
calculation process of daily boll index
(1) calculate the sum of closing prices of Ma = n-day ÷ N
(2) calculate the standard deviation MD = the sum of the two powers of (c-ma) of the square root (n-1) day divided by N
(3) calculate the Ma of MB, up and DN lines MB = (n-1) day, up = MB + K × MD DN=MB－k × MD (k is a parameter, which can be adjusted according to the characteristics of the stock. Generally, the default value is 2)

the expression of Boll index:
in the stock market analysis software, the boll index consists of four lines, namely the up line, the MB line, the DN line and the price line. The upper rail line up is the connecting line of up value, which is indicated by yellow line; The middle rail line MB is the connecting line of MB value, which is indicated by a white line; The lower rail line DN is the connecting line of DN value, which is indicated by purple line; The price line is represented by the US line and the color is light blue. Just like other technical indicators, in actual combat, investors do not need to calculate boll indicators, but mainly understand the calculation method and process of boll, so as to grasp the essence of Boll indicators more deeply and lay the foundation for the use of indicators.

1、 Definition: boll index, or boll index, its English full name is "Bollinger Bands". Boll was created by Mr. John Bolling. It uses statistical principles to calculate the standard deviation and the confidence interval of the stock price, so as to determine the fluctuation range and future trend of the stock price. It uses the wave band to show the safe high and low price of the stock price, so it is also called Bolling band

Second, the significance of the upper, middle and lower trajectories in the boll index:

1. The moving range of the stock price channel formed by the upper, middle and lower trajectories in the boll index is uncertain, and the upper and lower limits of the channel change with the fluctuation of the stock price. Under normal circumstances, the stock price should always be in the stock price channel. If the stock price deviates from the stock price channel, it means that the market is in an extreme state

2. In the boll index, the up and down track of the stock price channel is the highest and lowest price to show the safe operation of the stock price. Up track, middle track and down track can support the operation of stock price, while up track and middle track sometimes exert pressure on the operation of stock price

3. Generally speaking, when the stock price is running above the middle track of brin line, it indicates that the stock price is in a strong trend; When the stock price runs below the middle line of brin line, it shows that the stock price is in a weak trend

Third, index strategy:

1. When the upper, middle and lower trajectories of brin line run up at the same time, it shows that the strong characteristic of stock price is very obvious, and the stock price will continue to rise in the short term, so investors should firmly hold shares to be up or buy at bargain

When the upper, middle and lower trajectories of brin line run downward at the same time, it shows that the weak characteristic of stock price is very obvious, and the stock price will continue to fall in the short term, so investors should firmly hold the money and wait or sell at a high price

3. When the upper track of brin line is running downward, while the middle track and lower track are still running upward, it shows that the stock price is in a consolidation trend. If the stock price is in a long-term upward trend, it indicates that the stock price is a strong consolidation on the way up, and investors can hold stocks and wait-and-see or buy at low prices in a short term.

if the stock price is in a long-term downward trend, it indicates that the stock price is a weak consolidation on the way down, and investors should mainly hold money and wait-and-see or rece their positions at high prices

The upper trajectory of brin line moves up, while the middle trajectory and the lower trajectory move down at the same time, indicating that the stock price will go through a round of decline, and the extent of decline will be determined by the size of the opening. On the contrary, the lower trajectory of brin line moves down, while the middle trajectory and the upper trajectory move up at the same time, indicating that the stock price will go through a round of rise, and the extent of rise will be determined by the size of the opening

5. When the upper, middle and lower trajectories of brin line are running horizontally almost at the same time, it depends on the current trend of stock price

Boll should be used with KDJ index more effectively

4. Calculation formula:

middle track = n-day moving average

upper track = middle track + double standard deviation

lower track = middle track - double standard deviation

standard deviation MD = sum of square root (n-1) day (c-ma) to the power of two divided by n

4. John Bollinger, a market analyst and critic of CNBC, invented a stock trading tool called "Bollinger line" in the early 1980s />1. When the stock price goes up through brin's online limit, there is a high probability of file reversal
2. When the stock price falls through the lower limit of brin line, there is a high probability of rebound
3. When the brin line vibration wave band narrows, it means that the change disk is around the corner
4. Boll should be used with% BB and width
5. If the switch parameter is set to 1, the graph is represented by four lines
the "four no" principle of bottom hunting on brin line. At the same time, it is a good buying opportunity to break the brin line and the bottom deviation sign when brin limit BB < 0

2. MFI can be regarded as RSI with turnover. a. When MFI < 20, it means that the short-term cooling of funds is too fast, and there is a short-term oversold signal of freezing point. B. MFI is around 20

5.

Boll index has three tracks: upper track has pressure on price, middle track represents direction, and lower track has support on price; As shown in the figure,

conventional indicators have their own characteristics and essence. How to use the advantages and discard the disadvantages is the premise of making good use of the indicators. More content can be accessed to the homepage of Oh to leave messages and exchange

6. Hello, brin line index calculates the "standard deviation" of stock price, and then calculates the "trust interval" of stock price. The index draws three lines on the graph, of which the upper and lower lines can be regarded as the pressure line and support line of stock price respectively, and there is an average line of stock price between the two lines. Generally speaking, the stock price will run in the channel formed by pressure line and support line. In the application of the index, the focus is on the fluctuation of the volatility band and the index or stock price crossing the volatility band. Generally speaking, when the wave band of brin line moves horizontally, it can be considered that the current trend is dominated by horizontal movement, which belongs to & quot; The range of normality & quot;. In this case, when the stock price goes up through the "on track", it will form a short-term return, which can be regarded as a short-term sell signal; When the stock price goes down through the "down track", there will be a short-term rebound, and this is the time for short-term buying. However, after a period of horizontal movement of the stock index or share price, the fluctuation band of brin line shows signs of narrowing, that is, when the "up track" and "down track" are close to each other, it means that the market will begin to change. At this time, if the stock price continuously goes through the "on track", it means that the stock price will move upward; When the stock price continuously crosses the "down track", it means that the stock price will go down. I wish you success in your investment.

7. Boll index detailed explanation: the application of brin line in investment

brin channel line is a practical technical index designed according to the principle of standard deviation in statistics. The index uses the wave band to show its safe high and low price. The stock price moves in the band range of "upper limit" and "lower limit". When the stock price increases, the band range will widen; When the range of rise and fall shrinks, the band will narrow. Referring to brin line for trading, it can not only indicate the support and pressure level, show the overbought and oversold areas, and then indicate the operation trend, but also effectively avoid the usual technical trap of the main force - luring more or empty. The winning rate of operation is higher than KDJ, RSI or even MACD and other technical means, especially suitable for band operation

composition: Generally speaking, brin channel line is composed of upper, middle and lower track lines, but if the switch parameter is set to 1, the graph is represented by four lines. The upper rail and the lower rail are located on the outermost side of the channel, which are the pressure line (up line) and the support line (down line) of the trend respectively; The middle track is the average price. In most cases, the price is always running in a band composed of up and down tracks, and the position of the track is automatically adjusted with the change of the price. The width of the band shows the range of price change. The wider the band, the greater the price change

strength: similar to RSI and other technical indicators, the brin channel line also evaluates the strength of the trend according to the position of the price in the brin channel. When the price line is above the brin line, the trend is strong; Below the brin line, the trend is bearish. The two poles of brin passage are upper orbit and lower orbit, indicating very strong and very weak

1. When the stock price crosses the pressure line of the upper limit, the selling point signal is negative

2

3

4. When the stock price crosses the middle line from top to bottom, it is a sell signal

5. When the stock price goes up and crosses the "upper limit", it will form a short-term sell back, which is a short-term selling opportunity

6. When the stock price goes down through the "lower limit", it will form a short-term rebound, which is a short-term buying opportunity

7. When the belt area of brin line moves horizontally, it can be regarded as in the "normal range". At this time, the reliability is quite high by using 5 and 6 methods. If the zonal area moves to the upper right or lower right, it is out of normal and has special significance

8. When the wave band narrows, intense price fluctuations may occur at any time. After a period of intense fluctuation, the stock price will graally flatten. The power of long and short needs to rethink, sort out and wrestle. When both sides are in the mood of indecision, the fluctuation of stock price becomes more and more ll, which makes the "upper limit" and "lower limit" of brin line closer and narrower. This situation is "calm before the storm", so we should be careful

principles: the main theoretical principles of brin line are as follows:

1. When the price crosses down line from bottom to top, it can be regarded as a buying signal

2. When the price crosses the middle line from bottom to top, it may speed up the upward trend, which is a signal to buy more

3. When the price fluctuates between the middle line and the up line, it is a long market and can hold more or add more

4. After running between the middle line and the up line for a long time, the price falls below the middle line from top to bottom as a sell signal

5. When the price fluctuates downward between the middle line and the down line, it is a short market and can be held short or put up

skills: in actual combat, investors still need to master some operation skills

1. When the price has been rising steadily along the upper track of brin channel, the strong feature is particularly obvious. It is advisable to take back the middle track as a low buying point, take the middle track as an important stop loss line, and take the 4,9,18 day moving average system as a reference

2. If the price goes up and down for 3 days or goes out too much, but the transaction and position cannot be enlarged continuously, we should be alert to the risk of callback confirmation. On the contrary, when the price falls out of brin's down track and changes hands more actively, with the continuous enlargement of transactions and positions, the price is always hovering, which is likely to form a periodic bottom

experience: the two-day rule: if the brin medium rail leveled after a long-term sharp fall, or leveled after a correction in the rising trend, there is an upward turning point, and the price is also stable above the medium rail within two days, multiple intervention can be considered

10% principle: if the price is running above the medium rail, the opening of brin line will graally narrow, that is, the upper rail, medium rail and lower rail will graally approach. When the value difference between the upper and lower rails approaches 10% (daily line), it is the best time to buy. At this time, if the transaction and position can be significantly enlarged, the signal of price upward breakthrough will be more clear. The narrowing of brin line is the signal to start the market, and the opening again is the best time to add weight.

8. Brin line, also known as envelope line (boll), is one of the technical indicators often used in the stock market. It reflects the fluctuation of stock price. The brin line in Qianlong dynamic index chart consists of three lines, the yellow line (up) on the top is the resistance line, the pink line (down) on the bottom is the support line, and the white line (MB) in the middle is the average line. When the stock price is consolidated, the resistance line and support line contract, which is called closing; When the stock price breaks up or down, the resistance line and support line open, which is called the opening, proving that the stock price is about to have a big fluctuation. The general application rule of brin line is that when the stock price breaks down the support line, the buying point appears, while the selling point appears when the stock price breaks down the resistance line. The average is an important support or resistance to test whether a trend (whether rising or falling or consolidation) can continue. Brin line has many functions, so it is very effective and convenient to use. Once mastered, the signal is clear, and the use is flexible, it is loved by professional investors. At the same time, it is also one of the most commonly used technical indicators in the international financial market
operating characteristics
in the process of consolidation, the stock price fluctuates in a certain range, and the appropriate way is to sell high and absorb low. Every fluctuation consumes the enthusiasm of investors to chase up and kill down, and consumes the energy of fluctuation. Therefore, in the process of consolidation, the amplitude of stock price is always graally declining. When the amplitude is so small that there is no room for profit, the game can not continue to play. At this time, some people will start to seek to break through the consolidation range and find new space to continue to play the game, so they are brewing to change the market; Quiet and vivid
in the process of breakthrough, the stock price broke through the original consolidation range and started a rapid rise and fall. Unless the makers highly lock the chips, whether it's up or down, this rapid movement will make the participants unstable, cause huge short-term shock energy, and cause resistance to continue to rise and fall. At the same time, this shock energy also needs to be fully utilized. Therefore, after a period of rise and fall, it is necessary to re-enter consolidation, graally consume shock energy, stabilize people's mentality, and then re brew the next breakthrough. The so-called & quot; Dynamic extreme proces static & quot;.

9. Bbiboll:

1. When the upper, middle and lower trajectories of bbiboll run up at the same time, it shows that the strong feature of stock price is very obvious, and the stock price will continue to rise in the short term, so we should firmly hold shares to wait for rise or buy at bargain
2. When the upper, middle and lower trajectories of the long short brin line run downward at the same time, it shows that the weak characteristic of the stock price is very obvious, and the stock price will continue to fall in the short term, so we should firmly hold the money and wait or sell when it is high
3. When the upper track of the long short brin line is running downward, while the middle track and the lower track are still running upward, it shows that the stock price is in a consolidation trend. If the stock price is in a long-term upward trend, it indicates that the stock price is a strong consolidation on the way up, and we can hold shares and wait-and-see or buy on short-term basis; If the stock price is in a long-term downward trend, it indicates that the stock price is a weak consolidation on the way down. We should hold the money and wait or rece the position when the price is high
4. When the upper, middle and lower tracks of the Duokong brin line are closed very small (within 1.04), they are faced with a change of direction, which should be judged according to other main and auxiliary chart indicators
5. When the upper, middle and lower trajectories of the long short brin line are running horizontally almost at the same time, it depends on the current trend of the stock price to judge (up or down)
6. The stock price is strong above the medium rail, but weak below the medium rail.

10. 1、 The principle of Boll index
boll index is a very simple and practical technical analysis index designed by John Brin, an American stock market analyst, according to the principle of standard deviation in statistics. Generally speaking, the movement of stock price always changes in a certain range around a certain value pivot (such as moving average, cost line, etc.). Based on the above conditions, brin line index introces the concept of "stock price channel", which holds that the width of stock price channel changes with the fluctuation of stock price, and the stock price channel has variability, It adjusts automatically as the share price changes
just because of its flexibility, intuition and trend, boll index has graally become a popular index in the market which is widely used by investors
among many technical analysis indexes, boll index is a special one. The vast majority of technical indicators are constructed by quantitative methods, and they do not rely on trend analysis and form analysis,
while boll indicators are closely related to the form and trend of stock price. The concept of "stock price pass" in boll index is the direct manifestation of stock price trend theory. Boll uses "stock price channel" to display all kinds of price of
stock price. When the stock price fluctuates very little and is in consolidation, the stock price channel will narrow, which may indicate that the fluctuation of stock price is in a temporary calm period; When the fluctuation of stock price exceeds the upper track of narrow stock price channel,
indicates that the extremely fierce upward fluctuation of stock price is about to begin; When the fluctuation of stock price exceeds the
down track of narrow stock price channel, it also indicates that the extremely fierce downward fluctuation of stock price will begin
investors often encounter two most common trading traps: one is the buy low trap. After investors buy at the so-called low level, the stock price does not stop falling, but keeps falling; The second is the trap of selling high. After the stock is sold at the so-called high point, the stock price rises all the way. Bollinger line especially uses Einstein's theory of relativity, and holds that all kinds of markets are interactive, and all kinds of changes within and between markets are relative, and there is no absoluteness.
the level of stock price is relative, and the stock price above or below the upper trajectory only reflects that the stock price is relatively higher or lower, Before making investment judgment, investors should also refer to other technical indicators, including price volume coordination,
psychological indicators, analogical indicators, market related data, etc
in short, the stock price channel in boll index plays an important reference role in predicting the future market trend, and it is also a unique analysis method of brin line index< Second, the calculation method of Boll index
among all the index calculation, the calculation method of Boll index is one of the most complex, in which the concept of standard deviation in statistics is introced, which involves the calculation of medium trajectory (MB), upper trajectory (up) and lower trajectory (DN)
in addition, like other indicators, e to the different calculation cycle, the boll indicators also include
daily boll indicators, weekly boll indicators, monthly boll indicators, annual boll indicators and minute boll indicators. The daily boll index and weekly boll index are often used to study and judge the stock market. Although the values of
are different, the basic calculation method is the same< Taking the calculation of daily boll index as an example, the calculation method is as follows:
1. Calculation formula of daily boll index
middle track = n-day moving average
upper track = middle track + twice standard deviation
lower track = middle track - twice standard deviation
2. Calculation process of daily boll index
(1) calculation of Ma
MA = sum of closing prices in n days ÷ N
(2) calculate the standard deviation MD
MD = sum of square root n days (c-ma) divided by N
(3) calculate MB, up and DN lines
MB = (n-1) days of Ma
up = MB + 2 × MD
DN=MB－2 × MD
in the stock market analysis software, the boll index consists of four lines, namely the up line, the MB line,
the DN line and the price line. The upper rail line up is the connecting line of up value, which is indicated by yellow line; The middle rail line
MB is the connecting line of MB value, which is indicated by white line; The lower rail line DN is the connecting line of DN value, which is shown in the purple line table
; The price line is represented by the US line and the color is light blue. Like other technical indicators,
investors do not need to calculate boll indicators in actual combat, but mainly understand the calculation method and process of boll, so as to
master the essence of Boll indicators more deeply and lay the foundation for the use of indicators< Section 2 general research and judgment criteria of Boll index
the general research and judgment criteria of Boll index mainly focus on
I. The significance of the upper, middle and lower trajectories of Boll index
1. The moving range of the stock price channel formed by the upper, middle and lower trajectories of Boll index is uncertain, and the upper and lower limits of the channel change with the fluctuation of stock price. Under normal circumstances, the stock price should always run in the stock price pass
channel. If the stock price deviates from the stock price channel, it means that the market is in an extreme state
2. In the boll index, the up and down tracks of the stock price channel show the highest price and the lowest price of the safe operation of the stock price. The upper track, middle track and lower track can support the operation of stock price, while the upper track and middle
track sometimes exert pressure on the operation of stock price
3. Generally speaking, when the stock price is running above the middle line of brin line, it indicates that the stock price is in a strong trend
when the stock price runs below the middle line of brin line, it indicates that the stock price is in a weak trend< Second, the relationship among the upper, middle and lower trajectories of Boll index
1. When the upper, middle and lower trajectories of brin line run up at the same time, it shows that the strong feature of stock price is very obvious,
the stock price will continue to rise in the short term, and investors should firmly hold stocks to be up or buy at bargain
2. When the upper, middle and lower trajectories of brin line run downward at the same time, it shows that the weak characteristic of stock price is very obvious,
the stock price will continue to fall in the short term, so investors should firmly hold the money and wait or buy out when the price is high
3. When the upper track of brin line is running down, while the middle track and lower track are still running up, it shows that the stock price is in a consolidation trend. If the stock price is in a long-term upward trend, it indicates that the stock price is a strong consolidation on the way up, and investors can hold shares and wait-and-see or buy on short-term basis; If the stock price is in a long-term downward trend, it indicates that the stock price is a weak consolidation on the way down, and investors should mainly hold money and wait or rece their positions at high prices
4. The upper rail line of brin line runs upward, while the middle rail line and the lower rail line run downward at the same time, which is very unlikely.
no research and judgment will be made here
5. When the upper, middle and lower trajectories of brin line are running horizontally almost at the same time, it depends on the current trend of stock price
(1) when the stock price has been falling for a long time in the early stage, the three lines of brin line begin to move laterally, which indicates that the stock price is at the bottom stage of construction, and investors can start to build a small number of positions in batches. Once the three
lines diverge upward, the buying strength can be increased
(2) when the stock price is in a small upward trend in the early stage, three lines of brin line begin to move laterally,
indicates that the stock price is in the upward stage of consolidation, and investors can hold shares to be up or buy on the low side in the short term, once the three lines diverge upward, they can buy in the short term
(3) when the stock price just experienced a round of sharp decline, the three lines of brin line began to move horizontally, indicating that
the stock price is in the downward stage of consolidation. Investors should mainly hold money and wait and see and lose weight every high. Once the three lines diverge downward, they should resolutely clear their positions and leave the market
(4) the possibility of three lines of brin line moving laterally at the top is very small, and it is not studied here
3. The relationship between the U.S. line (or K line, the same below) and the brin line, the middle track and the lower track
1. When the U.S. line breaks through the brin line from below the brin line, it indicates that the strong characteristics of the stock price begin to appear, the stock price will rise, and investors should mainly buy stocks in the medium and long term
2. When the U.S. line breaks through the brin line from above the middle line, it indicates that the strong trend of the stock price has been established, and the stock price may rise sharply in the short term. Investors should mainly hold shares to be raised or buy in the short term
3. When the U.S. line breaks through the brin line, its movement direction continues to go up. If the movement direction of the brin line's
upper, middle and lower tracks also goes up at the same time, it indicates that the strong characteristics of the stock market remain, and the stock price will rise in a short period of time. Investors should firmly hold shares and wait to rise, Only when the movement direction of the U.S. line begins to show signs of turning downward
will we pay close attention to whether the market turns
4. When the U.S. line moves in the direction of brin line for a period of time, if the U.S. line starts to turn down, investors should be very careful. Once the U.S. line turns down and breaks through the brin line track, it indicates that the short-term strong market of stock price may end and the stock price will fall sharply in the short term. Investors should buy stocks in a short time Leave and see. Especially for those stocks that have a large short-term rise
5. When the U.S. line breaks through the brin line from above and down, if the upper, middle and lower trajectory of the brin line also starts to move down at the same time, it indicates that the short-term strong market of the stock price is coming to an end, and the short-term trend of the stock price is not optimistic. Investors should focus on losing weight every high
6. When the U.S. line breaks through the middle track of brin line from above to below, it indicates that the strong market in the early stage of the stock price has ended, and the medium-term downward trend of the stock price has formed, so investors should sell the stock in time
if the upper, middle and lower lines of brin line are down at the same time, it can be more confirmed
7. When the U.S. line goes down and continues to go down, it indicates that the stock price is in an extremely weak position. Therefore, investors should firmly hold money and wait-and-see and try not to buy stocks
8. When the U.S. line has been running off the brin line for a period of time, if there is a sign that the U.S. line is turning up, it indicates that the stock price will stop falling and stabilize in the short term, and investors can build positions on a small amount of dips
9. When the U.S. line breaks through the brin line from below the brin line, it indicates that the short-term situation of the stock price may pick up, and investors can buy stocks in a timely and appropriate manner to make a short-term rebound
10. When the U.S. line is always above the medium track line and moves upward together with the medium track line, it indicates that the stock price is in the process of strong rise. As long as the U.S. line does not fall below the medium track line, investors are determined to hold shares all the way
11. When the U.S. line is always below the medium track line and moves downward with the medium track line, it indicates that the stock price is in the process of weak decline, as long as the U.S. line does not move downward
