Bollinger Bands also known as the envelope (boll), is a technique frequently used for the stock market one of the indicators, which reflects the situation of price fluctuations. Qian dynamic indicator diagram Bollinger Bands formed by the three, above the yellow line (up) is the resistance line, below the pink line (down) is a support line, in the middle of the white line (mb) for the average. When the stock consolidation, the resistance line and support line contract, known as the heal; stock price up or down when you break the resistance line and support line open, known as the opening show will have a large stock price fluctuations.
Bollinger Bands use the general rule is that when the stock price down the line when the selling points breakdown support the emergence of a selling point upward puncture resistance occurs. The average line is the test of a trend (either up or down, or consolidation) it is able to continue the important support or resistance.
But after I applied a long observation, found that the law does not in any market situations are applicable, but only an upward trend in the consolidation or have a good indicative, but in a down trend, for the below support line breakdown is not really time to buy, investors can refer to the deep technology September 10, 1999 to November 10, 1999 Japanese-k-line trend, in the October 19-21 Brin line support line has been breakdown, but the stock is still down more than, if rashly Jiancang bound to suffer, so many examples, the investors can own textual research. After a lengthy summary as I found that Brin line appears to be an excellent long-term trend indicators, while Brin shut up go to the opening line from when the stock end of the consolidation that will soon have a dramatic volatility in the stock price breakthrough direction, marking the movement direction of future trends. That is, stock prices upward break the resistance line, it is an upward trend in the other hand, will be the decline. At the same time. The average line and the resistance (or support line) composed of upstream (or downstream) channel to grasp the long-term stock price movements have a strong indication. Above the pedestrian, for example, stock prices can be seen near the line in the average short-term selling points, price, or close to breakdown resistance can determine the short-term selling point, but for non-short-term operation need only grasp the average of the effective support you can determine whether the upward trend continues . On the contrary, the downside to judge as well. Investors can refer to the Clever (600,799), Nantong Machine Tool (600,862), Quanxing shares (600,799) and other firms can clearly see the role of Blin-line instructions, and then further look at other stocks in order to master the application of Bollinger Bands .
Bollinger Bands indicative addition to the above, there is a short-term indication. I use observation for a long time, most of them come true, but investors keep in mind is limited to short-term speculation, there is some profit out to be decisive.
Application of rule is this: When a stock price volatility over time is very small, as reflected in the performance of online Brin, stock price volatility with long-term narrowed, and in a trading day, the stock trading volume in the larger co-ordination Bollinger Bands Under the closing price of breaking the resistance line at a time when Bollinger Bands marked by a close up to open, this time investors should be snapped up (from the date of the k line graph can be clearly seen), it is because, transfer the stock from weak to strong, short-term momentum is not just on the red one day, short-term there must be a new high there, so you can intervene decisively. Recent stocks investors can refer to Zhejiang Guangsha (600,052), CDC (600,641), Yiankeji (0008), if intervention to break through the day, there will be more than 10% of the short-term profits.
