1. bell line (bell) function
1. bollinger bands can indicate the position of support and pressure;
2. The bollinger Band can show overbought and oversold;
When the stock price falls to the lower rail line of BOLL and is supported, we can buy a small amount when the stock price starts to rise. When the stock price crosses the middle track and becomes stronger, you can add positions. As shown in the figure below:
The stock price is at the bottom. When the stock price hit the lower rail of the bollinger band, it was supported. When the stock price support level is not broken and the stock price rises slowly, you can buy a small amount, because the market is in its infancy and you can't hold a large number of positions. When the stock price returns above the middle rail, you can add positions.
3. Bollinger bands can indicate trends.
4. Bollinger Bands have the function of channels.
Because of its multiple functions, forest wiring is very effective and convenient to use. Once mastered, the signal is clear and flexible to use. It is deeply loved by professional investors and is also one of the most commonly used technical indicators in the international financial market.
2. The general usage of cotton boll indicator is as follows:
(1) When the price breaks through the middle track of the BOLL indicator from below, it shows that the strong characteristics of the stock price begin to appear and the stock price will rise. Investors should mainly buy stocks in the medium and long term.
(2) When the price is above the middle rail of the BOLL indicator and breaks through the bollinger band, it indicates that the strong characteristics of the stock price have been established and the stock price may rise sharply in the short term. Investors should mainly hold stocks that will be raised or purchased in the short term.
(3) When the price breaks through the upper rail of the BOLL indicator and its moving direction continues upward, if the upper, middle and lower rails of the Bollinger Band move upward at the same time, it shows that the strong characteristics of the stock market are still there, and the stock price will rise in the short term. Investors should continue to hold stocks until the movement direction of the K-line begins to show signs of turning down, and should pay attention to the selling signal of market reversal.
(4) When the price runs above the BOLL indicator for a period of time, investors should be extra careful if the K-line starts to move downwards. Once the K-line breaks through the bollinger band, it indicates that the short-term strong market of the stock price may end, and the stock price is more likely to fall in the short term. Short-term investors should sell stocks in time and wait and see. Especially those stocks with large short-term gains.
(5) When the price breaks through the upper rail from the top of the BOLL indicator, if the movement direction of the upper, middle and lower rails of the BOLL indicator also starts to decline 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 mainly lighten their positions on rallies.
(6) When the price breaks through the bollinger band middle track above the boll index middle track, it shows that the strong market in the early stage of the stock price has ended and the mid-term downward trend of the stock price has been formed. Short-term and mid-line investors should sell their stocks in time. This conclusion will be more confirmed if the upper, middle and lower lines of the BOLL index also run down at the same time and there is a downward turning point.
(7) When the price falls below the BOLL index and continues to fall, it shows that the stock price is in an extremely weak market. Investors should sell their positions and wait for funds, and should not buy any more stocks.
(8) When the price runs below the lower rail of the BOLL indicator for a period of time, if the movement direction of the K-line shows signs of turning head upwards, it indicates that the stock price will stop falling and stabilize in the short term, and investors can open a small amount of positions at this time.
(9) When the price breaks through the Bollinger band from the lower rail to the upper rail of the boll indicator, it means a short T ..
After a long period of market bottom finishing, the upper and lower rails of the Bollinger Band gradually contracted, the distance between the upper and lower rails became smaller and smaller, and the market price suddenly rose rapidly. At this time, the upper rail of the bollinger band also rises rapidly, and the lower rail moves downward at an accelerated speed, so that the shape between the upper rail and the lower rail of the bollinger band forms a special shape similar to a big horn, and the bell mouth of the bollinger band is called an open bell mouth.
Open horn is a form that shows a big upward breakthrough in the short-term market. It is the trend when the market is facing upward changes after a long-term low-level sideways bottoming. The direction of the upper and lower tracks of the forest line is opposite, but it is very strong, which indicates that the bulls will gradually become stronger and the bears will gradually fail, and the market will be in a short-term sharp rise.
The shape of the bell mouth must meet two conditions:
First, the market has to go through a long period of sideways consolidation in the middle and low positions. The longer the consolidation time, the smaller the distance between the upper and lower rails, and the greater the future increase;
Second, when Bollinger began to speak, there should be a considerable volume of transactions.
The establishment of the bell mouth shape is based on the K-line breaking up the upper rail line and the price band breaking up the medium and long-term moving average. For the appearance of the trumpet, if investors can do more in a short time, they will make a lot of money.
(2) convergent bell mouth
Convergence trumpet means that after a strong rise, the upper rail of Brin begins to turn around and approach the middle rail downwards, and the lower rail of Brin continues to approach the middle rail upwards. At this time, the third rail of Brin forms a gradually narrowing convergent bell mouth. The bell mouth often appears at the end of a wave of rising, which means the beginning of short-term adjustment. Investors should avoid risks in time. To confirm the reliability and signal strength of the convergent horn, please pay attention to the following two points:
First, the bigger and faster the previous increase, the higher the bearish reliability of the convergence angle and the stronger the downtrend signal.
Second, the upper rail of the bollinger band is obviously downward, the stock price falls below the short-term price moving average, and even falls below the middle rail, and the short-term price moving average crosses downward.
(3) Tight mouth bell mouth
When the market has gone for a long time, the upper and lower rails of the Bollinger Band gradually move closer to the middle rail, and the distance between the upper and lower rails is getting smaller and smaller, which leads to the market price.
The lattice oscillates repeatedly at a low position. At this time, the upper rail of the bollinger band is still running down, while the lower rail is slowly rising. In this way, the shape between the upper rail and the lower rail of the bollinger band becomes a special shape similar to an inverted horn. We call this bell mouth of the bollinger band a tight bell mouth.
The forming conditions and confirmation standards of tight mouth trumpet are relatively loose. As long as the market has fallen sharply for a long time, the transaction has shrunk extremely, and the distance between the upper and lower rails has become smaller and smaller, it can be considered that the tight-lipped horn has initially formed. When tight horns appear, investors can wait and see, or they can open a small number of positions.
Four, the use of bollinger band boll index matters needing attention:
1, the bollinger band parameter setting shall not be less than 6, and the static dry heave value is usually10; Dynamic stem length is generally set to 20.
2. When using the bollinger Band, pay attention to whether it is in the normal area or the abnormal area. In the abnormal area, we can't simply follow the principle of breaking the upper limit and buying the lower limit.
3. It is easy to catch bull stocks by narrowing the opening at a low level, but at a high level or once it is reduced, the stock price will break down and there will often be more room for decline.
4. Bollinger Bands can be used in conjunction with other indicators, and the effect will be better, such as volume and KDJ indicators.
Related questions and answers: I will explain the usage of weekly bollinger bands and daily bollinger bands to you in vernacular. First, you should judge the trend from the weekly and daily lines. If the trend is downward and the daily signal is too frequent, then the big cycle is more accurate. If the weekly trend of BOLL is upward and the daily retracement is a buying point, then BOLL is a relatively comprehensive indicator, which can be used as a separate question and answer related to the trading system: What are the trading skills of stock BOLL indicators? How to easily grasp the buying and selling points? Mastering the buying and selling points of stocks is a matter with strong comprehensive ability. Some people have been trading stocks for more than ten years, and even put more energy and time on it than on his baby. Some people are very specific about the research indicators, and the final results obtained by these people are not so satisfactory. This shows that this is not an easy task.
Sometimes giving is not necessarily rewarding, and sometimes it depends on your understanding.
To understand BOLL's trading skills, we must first understand what BOLL is.
BOLL is an indicator that most investments will use. Whether you are doing foreign exchange, futures or stocks, it belongs to a price path indicator. Using big data to calculate a standard deviation and high-low risk interval, we can determine the trend of stock price and a fluctuation interval, so it is also called bollinger band.
Although BOLL has only three simple lines, it is not so easy to use it well. Next, I will share the trading signal diagram of BOLL indicator.
1, buy signal: the price goes up and down.
2. Selling signal: it falls below from top to bottom between the center line and the upper rail line.
3. Add positions to buy: wear the price midline.
4. Long market: The stock price fluctuates between the middle line and the upper rail line.

I usually use three sets of index systems. One set is my own upgraded index of entanglement theory.
