Bollinger Bands are professional investors and some of the old shareholders, one of commonly used technical indicators. This indicator belongs to the path index, stock prices generally in the upper and lower limit within the range of fluctuation. Dynamic Qian Boolean line formed by the three lines, the threshold of support lines, maximum resistance, there is a median line of the boundary. static Qian Boolean line formed by the four. the top one is the trend line resistance, known as bolb1, white solid line indicates ; the bottom line is the trend of a support line, known as bolb4, with the purple solid line represents; bolb1 comprises bolb2, with yellow dotted lines; bolb4 close to a line on top of another is called bolb3, a light blue Color solid line. In the four lines constitute a caps, floors, sub-cap, sub-floor, stock prices often fluctuate up and down within the band range, this band width as the area the size of stock price volatility changes, stock prices rose greater degree of decline, the leading areas will widen, Change margins, the band will be narrowed zone. Breen line width can be changed as the stock price is automatically adjusted position. Because of this variation so that Bollinger Bands with flexible and adapt to trends, characteristics, both with the nature of the channel, but also the channel width can not be changed to overcome the weaknesses.
Bollinger Bands have the following major functions:
1, cloth than the line to direct support and pressure position; 2, Bollinger Bands can show overbought, oversold; 3, Bollinger Bands can indicate trends; 4, Brin-line with the role of channel
Bollinger Bands due to have a variety of functions, easy to use, very effective once mastered. Signals a clear, flexible, professional investors have been loved, but also the international financial markets, one of the most commonly used technical indicators.
1, in the normal range, the Bollinger Bands use the techniques and methods
Normal range is usually run in a certain price within the band width, which is characterized by a stock crash is not very rose, in a state of relative balance, this time using the Boolean-line method is very simple.
1, when the stock price through the ceiling of the pressure line (dynamic limit the line of pressure, static pressure on top-line bolb1), the selling point signal;
2, when the stock price through the lower support wire (dynamic lower support line, the static of the most under the support line bolb4), the selling points, signal;
3, when the stock price up by the next across the line (static from bolb4 through bolb3) when the coded signal;
4, when the stock price down to cross the boundary from the previous (static from bolb1 across bolb2) when, in order to sell signals.
Second, unilateral increase in the use Bollinger Bands Quotes
In a strong market, shares a continuous rise in stock prices will usually run between the bolb1 and bolb2, when a continuous rise in stock prices a long time, the share price on the wear bolb1, the next day and the next to wear bolb1 further break bolb2, driven bolb1 curve, there increase in the apparent switch from the flat inflection point, this time as a sell signal.
Third, the meaning of necking:
1, the share price decline after several waves, and then into a longer time often narrow order, when we find that the upper and lower Bollinger Bands minimal space, more and more narrow, more nearly. Intraday price displayed the highest price and lowest price difference is extremely small, short-term there is no profit margins, are often not even the fees are earned out, not active intraday trading volume scarce, investors should pay close attention to this necking, because a Great Quotes may be brewing, once the volume increases, stock prices rise, Bollinger Bands openings expand, up Quotes declared the beginning.
2, such as Bollinger Bands is extremely mechanized small openings at a high level, once the stock price down Po Wei, Bollinger Bands openings enlarge, a fall will be inevitable
.
4, Bollinger Bands openings meaning:
1, when the stock price from low to high after several waves rise, the Bollinger Bands the best and most under pressure line on the support line open to a great extent, and openings can not continue to enlarge into contraction, this was a sell signal, usually stock prices is followed by a sharp fall or adjust Quotes.
2, when the stock price fell sharply after several waves, the upper and lower Bollinger Bands can not continue to enlarge the opening, the maximum pressure line ahead of Bollinger Bands by necking-down, until Bollinger Bands lower support line followed by a bottom-up, when necking , a decline would be closed.
V. Notes on the use of Bollinger Bands
1, Brin-line parameter set not less than 6, the static Qian value is usually 10; dynamic Qian is usually set at 20.
2, using the Boolean line is to note that in the normal area or can identify abnormal areas, in the very state area can not simply sell to break the ceiling, breaking the principle of minimum purchase.
3, using openings to narrow, easy to capture in the low Niugu, but at a high level or if the necking, the price break down, and often there will be more room to fall.
4, Bollinger Bands can be used in conjunction with other indicators, the effect will be even better, such as volume, kdj indicators.
