What are Bollinger Bands What do Bollinger Bands mean

Boll indicator is also called Bollinger Bands indicator, its full name in English is "Bolinger Bands", Bollinger Bands (Boll) was created by Mr. John Bollinger, which uses statistical principles to find the standard deviation of stock prices and their trust intervals, so as to determine the fluctuation range and future trend of stock prices, and uses bands to show the safe high and low prices of stock prices, so they are also known as Bollinger bands. The upper and lower limits are not fixed and change with the rolling stock price. The Bollinger indicator and the Mike indicator are the same path indicators, and the stock price fluctuates within the upper and lower bounds, and the width of this band, which is the significance of the large Boll indicator with the amplitude of the stock price fluctuation.

The movement range of the stock price channel formed by the upper, middle and lower bands in the indicator 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 operate within the stock price channel. If the stock price is running out of the stock price channel, it means that ** is in an extreme state.

2.In the Boll indicator, the upper and lower bands of the stock price channel are the highest and lowest levels that show the safe operation of the stock price. The upper, middle and lower bands can all support the operation of the stock price, while the upper and middle bands can sometimes exert pressure on the operation of the stock price.

3.Generally speaking, when the stock price is running above the middle band of the Bollinger Bands, it indicates that the stock price is in a strong trend; When the stock price is running below the middle band of the Bollinger Bands, it indicates that the stock price is in a weak trend.

The relationship between the upper, middle and lower bands of the Boll indicator in this paragraph.

1.When the upper, middle and lower bands of the Bollinger Bands run upwards at the same time, it indicates that the strong characteristics of the stock price are very obvious, and the stock price will continue to be ** in the short term, and investors should resolutely hold the stock to rise or take dips**.

2.When the upper, middle and lower bands of the Bollinger Bands run downward at the same time, it indicates that the weak characteristics of the stock price are very obvious, and the stock price will continue to ** in the short term, and investors should resolutely hold the currency or sell on the high.

3.When the upper band of the Bollinger Bands is running downwards, while the middle and lower bands are still moving upwards, it indicates that the stock price is in a consolidation situation. If the stock price is in a long-term upward trend, it indicates that the stock price is a strong consolidation on the way, and investors can hold the stock or take the dip; If the stock price is in a long-term trend, it means that the stock price is a weak consolidation on the way, and investors should wait and see or reduce their positions on the rise.

4.There are many possibilities that the upper band of the Bollinger Bands will run upwards and the middle and lower bands will run downwards at the same time.

5.When the upper, middle and lower bands of the Bollinger Bands are running horizontally almost simultaneously, it depends on the current trend of the stock price.

1. Introduction: This indicator is created by John Bollinger, first calculate the "standard deviation" of the stock price, and then find the "trust interval" of the stock price, this indicator and the MIKE indicator belong to the same "path indicator", and the stock price also fluctuates within the range of the "upper limit" and "lower limit", but BOLL only has an "upper limit" and a "lower limit", and the actual graph must also draw a stock price flat**.

The stock price wanders in the "upper limit" and "lower limit" of the band, the width of the strip area, with the size of the stock price fluctuation range changes, when the stock price rise and fall is large, the strip area will become wider, and when the rise and fall range is narrow and consolidated, the strip area will be narrower. In other words, the Bollinger Bands are variable, and they can automatically adjust their positions with the change of stock characteristics, because of their flexibility and adaptation to the current situation, making the Bollinger Bands one of the most commonly used technical indicators in the international financial market in recent years.

Second, the application of the law.

1.When the bands of Bollinger Bands move horizontally, they can be considered to be in the "normal range". At this time, when the stock price crosses the "upper limit" upward, a short-term pullback will be formed, which is a sell signal for **; When the stock price crosses the "lower limit" downward, it will form a short-term **, which is the buying opportunity for **.

2.When the strip moves towards the upper right and then the lower right, it is out of the norm. When the stock price continuously crosses the "upper limit", it implies that the stock price will move in the direction of **; When the stock price continuously crosses the "lower limit", it implies that the stock price will move in the direction of **.

Although the Bollinger Bands are pressure support indicators, they also have the characteristics of being overbought and oversold, and they can compensate for blind spots when used in conjunction with indicators such as ROC (Rate of Change) and CCI (Trending Indicator).

The Bollinger Bands (BOLL) indicator is one of the most common tools for technical analysis, which calculates the "standard deviation" of the stock price and then finds the "range" of the stock price.

1. The indicator draws three lines on the graph, of which the upper and lower lines can be regarded as the pressure line and support line of the stock price respectively, and there is a stock price flat between the two lines, and the parameters of the Bollinger Bands indicator are best set to 20. In general, the stock price runs in a channel formed by the upper and lower lines.

2. Like MACD, RSI, KDJ and other indicators, the silver BOLL indicator is also the most practical technical analysis reference index in the market.

3. It is composed of 4 lines, including B1 line, B2 line, B3 line and B4 line. Line b1 is an exponential (or ****) resistance line. The B4 line is the support line.

The width of the Bollinger Bands shows the magnitude of the change in the index or stock price. When the stock price is merged, the four lines contract, which is called **; When the stock price breaks out upwards or downwards, the four-line opens, known as the opening.

4. When the stock price breaks through the B1 resistance line upward, there is a selling point, when the stock price breaks through the B4 line downward, when the stock price rises (falls) along the resistance line (support line), although it does not break through the support line (resistance line), it also breaks through the B2 line (B3 line). It's also better to sell (buy) points. Exponential calculations are complex.

It doesn't need to be detailed. Friends of investors can be transferred from the dynamic and static of the money dragon. It is important to note that Dynamic Bollinger Bands are three-line, such as Dynamic Bollinger Bands.

Extended information: 1. The Bollinger Bands index is a very simple and practical technical analysis index designed by John Bollinger, an American analyst, based on the standard deviation principle in statistics. Generally speaking, the change of stock price always changes within a certain range around a certain value center (such as moving level, cost line, etc.), and the Bollinger Bands index is introduced into the "stock price channel" on the basis of the lack of banquet conditions in the previous year.

It is believed that the width of the stock price channel changes with the fluctuation range of the stock price, and the stock price channel is variable and will automatically adjust with the change of the stock price. Because of its flexibility, intuitiveness and trend, the BOL index has gradually become a popular index widely used by investors in the market.

2. Among the many technical analysis indexes, the BOL index belongs to a special index. The vast majority of technical analysis indicators are constructed using quantitative methods. They do not rely on trend analysis and pattern analysis, whereas the BOL indicator is closely related to the pattern and trend of stock prices.

The concept of "stock price channel" in the BOL index is an intuitive expression of the stock price trend theory. BOL uses "channels" to show the various channels of ****.

The Bollinger Bands indicator is divided into high lines, median lines, and low lines. The high line of the Bollinger Bands can be used as a reference for the resistance level, while the low line can be used as a reference for the support range. Under normal circumstances, when the three lines of the Bollinger Bands indicator are in a downward trend, and the stock price is running between the median line and the low line, it means that the stock price is in the ** trend.

When the three lines of the Bollinger Bands indicator are in an upward trend, and the stock price is running between the median line and the high line, it means that the stock price is in the ** trend.

Knowing that he was very common with Cowber and Scott, and regarded it as a matter of grace. According to relevant historical sources.

The Bollinger Bands (BOLL) indicator is one of the most commonly used tools for technical analysis, which calculates the standard deviation of the stock price and then finds the confidence range of the stock price. The indicator draws three lines on the graph, of which the upper and lower lines can be regarded as the pressure line and support line of the stock price, and between the two lines there is a stock price flat**, Huatai**'s one-stop wealth management platform - "Changle Wealth Pass" provides a wealth of investment and financial management series courses, hand-in-hand teaching you how to understand the technical indicators.
