Bollinger Bands is the use of wave band shows the level of safety stock price, when its volatility become smaller, while the wave with a narrow, the intensity of price fluctuations may then arise; if the high and low points across the band edges, one immediately returned wave band, then the correction will be generated; wave band began to move, it will in this way enter yet another wave band, which identify the target value for the considerable help.
If the combination of static indicators of the integrated use of Bollinger Bands, the actual better effect. The indicators are generally dynamic display of the three lines that if a switch parameter, graphics Take the 4 line indicates. Static indicator Bollinger Bands (bolbn) is constituted by the four lines, the outermost two of the trend support line (down line) and resistance (up line). As can be seen from the band-width of the stock magnitude of change. The more wide that the greater the change in stock price. It is the use of the principles of the theory is this: When stock prices through the outermost pressure line (support line), it said that selling (selling points) appears. When the stock price along the pressure line (support line) up (down) to run, although the stock did not pass through, but if the break back to the second line that is selling or buying point.
In practice, we will set the parameter value Bollinger Bands magic number 21, parameter value is better, I will study the laws of several years are summarized as follows: (1) stock from the bottom up through the down line, can be seen as reverse signal.
(2) The shares from bottom to top through the mb line, shares will accelerate the rise, is the Opening buy signal.
(3) mb line and up the share price fluctuated between lines when running bull market may be holding wait and see.
(4) shares a long time in the mb line and between lines running up from the top-down below the mb line sell signal.
(5) shares in the mb line and down line downward fluctuations between the short run when the market, holding cash at hand at this time investors should wait and see.
For example: Shen Baoan (000009) The unit in the bottom of this year, after Fanshen up 3.41 yuan from the bottom up through the down line, you can set up initially identified as reversal, radical investor will be able to intervene at this time, cautious type Investors may wait until the crossing again when interventional mb line. Holding all the way to the stagflation profit up 40%.
Note the use of the indicators: (1) the establishment of 21 parameter values, can not simply up to cross the line will be sold below the down line on the principle of buying as a standard.
(2) If shares a long sideways, opening narrowed, the above rule does not apply. The larger openings, there is a clear run up and down direction, using this law effective.
(3) the use of this rule, easy to capture the center line Niugu.
Using Boolean-band channels to find something for a
Under normal circumstances, the use of Bollinger Bands indicator of trading, the operation's success rate far better than the help of kdj, rsi or even moving average trading. Trading Using Bollinger Bands, will enable us to avoid making use of some commonly used technical indicators or Youkong trap of luring more, particularly in trial use in-band operation, in the following circumstances to be more accurate buy signal:
1, if the stock price above the rails in the run Bollinger Bands opening gradually narrowed, on the rails, the rail and lower rail and gradually approaching, when the value of the upper and lower rails close to 10% of the time difference, for the best time to buy. Significantly larger if the volume at this time, then the price break up the signal more clearly defined. Such as the Phoenix shares (related to, and the prices) (600,679) at the end of November 2000 to mid-December Bollinger Bands trend in the time period under the rail line Brin significantly narrowing spreads up and down rails just 10%, while nearly 12 In mid-month when its U.S. line has been Brin k-orbit, and the rail line running between, showing a strong feature of December 1 under the stock trading volume with a substantial upside, Bollinger Bands open quickly magnified the advent of a new round of rise. Bollinger Bands is a dark horse to start narrowing the signal, while the Bollinger Bands open re-amplification is the best time to buy.
2, when the stock price after a period of a moderate increase in short-term correction that followed Quotes, stock prices in the last orbit in the vicinity and then blocked the rail line back to Brin, if a firm in a row on the 3rd rail could be considered to intervene. Such as the Shenzhen Science and Technology (000021) The recent trend, the unit price by the end of April began to slowly climbed, the United States gradually all the plate, they form a rising trend, but touched on the track (May 21) when you meet resistance down to start the technical strong adjustment, dropping back in a few days later the U.S. rail line near the arrested, and the apparent volume shrinkage in the unit since June 4 firm in the track, this time the best buy for the short-term point. Another example is Guangzhou Iron and Steel shares (related, and the prices) (600,894) rebounded since bottoming out in January of this year, the United States under the rail line, after touching regain upward trend in February in rail firm Bollinger Bands, confirm to adjust the end of March 13 the impact on the Japanese stock rail, and then back on the track, the April 3 hit the track, the emergence of a unique selling points, followed by the number of the unit root Yangxian even close.
3, when a stock is always along the Bollinger Bands channels between the rails and the tracks are going up steadily, to shareholders or buy low mainly because it indicates the stock is in a strong bull trend among the four, stock prices fall a Boolean in the next track or rail firm involved could be considered. If the above GISC peaked in June last year, the decline in the stock repeatedly Pandie, stock most of the time in between the middle and lower rails running in January this year, after the plunge in a row, the stock hit a go under the rail, in February the Unit re stand firm in the track, in order to buy signal, followed by a continuous rise in share prices as expected Quotes. Brin line fall out of orbit bought examples refer to Henan pigeons (related, and the prices) (0544), which was in early January 2001, after all the way down, the U.S. cable channel in the Boolean run between rail and lower rail , February 22, 23, 26 dropped out of the stock plummeted under the tracks, but the February 27 stock return channel within the same day shall be the short-term buying opportunity, market price 8.50 yuan, then stock prices In a very short period of time rose to 10 yuan in the vicinity profit nearly 20%.
"Buy low sell high" is not simple: Using Boolean channel to buy low sell high,
Bollinger Bands are on the rails, the rail and lower rail 3 tracks, their overall operations have been able to clear instructions to run the center line of the three trends in individual stocks, namely, upward trends, downward trends and sideways trend. One rail line is the strength of the trend of individual stocks dividing line between the rail and upper rail of the regions in a strong area, stock prices of stocks running into a strong area referred to as a strong unit. A strong stock price will usually be repeated up between the upper rail, which provides investors with an opportunity for middle-band operation.

Stock-picking strategy In the "daily flow of funds ranked" the first screen units (Shenzhen and Shanghai stock market 23), the search for Bollinger Bands three tracks parallel to the rising stocks, this goal is to lock the rising channel up and down fluctuations and shocks of zero individual stocks. And then capture those volume continuous amplification, especially in recent days with the amount above the rails into the Boolean operation in the stocks. Because of this the shares of the stock has been activated, generally able to provide many investors buy low sell high up the channel, band arbitrage opportunities.
Time bargain-hunting
Target stock determined, investors can in 15 minutes k-line graph, using average system (3,21), the pagoda and other indicators to determine line and macd bargain-hunting opportunity. Once the k-line combination appears pulled to start form, the pagoda line 2 or 3 flat-bottomed meteoric rise to the green column and macd above the meteoric rise in the 0 axis, investors should be timely intervention, in most cases get a better band low selling points.
High-throwing time
K chart in 15 minutes, when the stock price crashing obv and rsi while the peak is a general increase in the channel for the parallel-band high selling point for the better, and when these two indicators are also in the Japanese charts at the same time to reach high levels, Investors should be phased out.
To note are: phased out, investors need to continue to follow the stock, when the 60-minute charts of the 21 were the amount of line back-pressure three-day phenomenon of the amount of line to be lifted, often indicate a low stock Suction opportunity come again.
Classic examples: Jiangling Motors (000550) The unit has since February 26 so far Bollinger Bands has built a significant increase in parallel channels, respectively, March 17, March 26 and March 31 offers three bargain-hunting High-throw opportunities. Similar stocks are FAW Car (000800), Science City (000,975), and Rainbow Holdings (000,503), etc., investors can take advantage of these laws in his possession a small test their skills.
After the stock fell over a period of time, there have been a larger decline in the stock hit the next track Bollinger Bands, the United States a stable line up, if the stock price to rise to Boolean online tracks bombs do to prepare to sell, and when the United States lines from on the rail lines near back on track in-line should be bold and to sell.
Typical examples of actual combat are the Shenzhen side, large (0055) in the January 4, 2001 ~ April 12, 2001 Bollinger Bands charts, the Unit from January 4 in a row substantial correction, stock prices down from 22 per to 15.30 yuan, the United States rail-line touches to the next, when arrested, and then a slight recovery in the U.S. line, and gradually return to the track above the track in the firm, after a few touches to the rail line Brin, 2001 4 9, 10, 11, is running above the rails in the last row, April 12 back on track within the appropriate time to sell an end that day, the highest price of 18.80 yuan, if the basic can be a good selling price to sell.
This method is mainly applied to short-term to sell the operation, while touching Brin rail line does not necessarily mean an important stock, see the top, only shows the current short-term profits drive stock higher, without a proper price drop, and further large l difficult, therefore, method has been applied to sell at the same time, consideration should be given in the callback to the Boolean line to buy the tracks to do to prepare.
For another example, Shenguo Shang (0056) Since December 13, 2000 ~ April 24, 2001 Boolean channel charts. Late last year, Shen Guoshang peaked at 14 yuan down, the United States-line all the way down several times, finally hit the next track after the February 23 this year, in breaking down under the tracks bottomed out rebounded the U.S. line to resume its rally, and to stop Wen confirmed Brin line adjustment of the end of the track, according to trading strategies 2, March 16 to become a short-term selling points. April 23 on the unit onto the rail, the next day back in orbit, it should sell the short-term, but we found a huge shock that day the stock once dropped to 11.39 yuan Brin line track, which appears a very rare short-term selling point, if the next day to buy 10% of the profits available.
Trading Strategy 3: When a stock is always along the Bollinger Bands channels between the rails and the tracks are going up steadily, with holdings mainly because it indicates the stock is in a strong bull trend among the stock Zhang Sheng The prime-time. And even if occasionally touching on the track can also be held, such as Changchun Changling (600.89 thousand) in August 2000 -2,000 11 months Bollinger Bands trend in paragraph at this point the unit steadily upward, the United States has always been run on the line in the track, between November 24, 27, 28, 29, rushed to the stock price above the rails into the accelerated rise in stock price back to November 30 under on the track, in order to sell short-term good point, and indeed the shares followed by a sharp correction, from the date of 18.80 yuan to 13.80 yuan down side has been stabilized.
When a stock is always along the Bollinger Bands channel between the rail and the next level by level down the track when that stock is in the down the process, not easily buy shares, patiently waiting for the arrival of a true buying opportunity until the see steep decline occurs, the stock fell out of Brin under the rail track or a firm may consider intervention.
Wanwei Hi-tech (600,063) is the United States and the next line in the rail tracks running between the stock and then return to the track and stand firm behind the buy example, see the January 2001 -2001 years, the Unit Bollinger Bands Chart . From early January all the way Yindie stock, stock prices always run between the middle and lower rails, and repeatedly hit the next track, but does not plunge straight, off the next track is still not intervene into the firm in March to re-stock track, March 14 from the track of the buy signal for Yang Xian, and indeed a continuous rise in share prices market, March 28 back on track to be sold, and April 20 of the heavy volume can also buy a firm in the rail income, and this band operation, when within one month to obtain not less than 20% of the short-term gains.
Brin line fall out of orbit bought examples refer to Henan Dove (0544) in early January 2001 - 2001 2 dated 23 Bollinger Bands charts. Same all the way down the same path in the Boolean rail between the rail and the next run, February 22, 23, 26 dropped out of the stock plummeted under the tracks, but the February 27 stock returns within the channel day shall be short-term buying opportunity, market price 8.50 yuan, if bought, followed by shares in a very short period of time rose to 10 yuan in the vicinity profit nearly 20%.
