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 the resistance line (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, the parameter value is better, I will study the laws of several years are summarized as follows:
(1) The shares from the bottom up through the DOWN line, can be considered as reversal signals.
(2) The shares from bottom to top across the MB line, shares will accelerate the rise, is the Opening buy signal.
(3) shares in the MB line and the UP line running between the volatility of the bull market may be holding wait and see.
(4) shares a long time in the MB line and the UP line between running from the top-down below the MB line for sell signals.
(5) shares in the MB line and DOWN downward fluctuations between the lines for the short run 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 lines, could be preliminarily identified as reverse established aggressive investor will be able to intervene at this time, cautious type Investors may wait until the trip across the MB line again when the intervention. Holding all the way to the stagflation profit up 40%.
