Bollinger Bands' 30-minute Tactics
Bollinger Bands are generally composed of three lines: the upper rail is the resistance line, the lower rail is the support level, and the middle rail is the moving average 10. When the stock price is consolidating, the resistance line and the support line contract, which is called necking. When the stock price breaks up or down, the resistance line and the support line open, which is called opening. Explain that the stock price is about to fluctuate greatly.
BOLL line is the most sensitive to the pull-up signal, so we can focus on the change of this indicator when grasping the opportunity to enter the market. If the 30-minute BOLL is combined with the daily BOLL, it is a good choice. We can identify whether the environment is safe by daily BOLL, and find the right entry and exit point by 30 minutes BOLL.
First, the daily K-line of the stock price is in the area between the middle track and the upper track, indicating that the short-term and medium-term stocks are on the rise, which is more suitable for short-term and ultra-short-term operations.
Second, the stock price 30 minutes K line breaks through the middle rail line from the bottom up, or the stock price is adjusted back to the middle rail line position, and it rises again because of the support of the middle rail line. This is a good short-term entry point.
Third, when the stock price rose from the middle rail position, the bell mouth of the Brin channel began to enlarge, and the trading volume increased significantly, indicating that the buying success rate was high at this time.
Matters needing attention in the use of bollinger bands: 1, the parameter setting of bollinger bands shall not be less than 6, and the static value is usually10; It is usually 20 when dynamically set; 2. When the opening price narrows, it is easy to catch bull stocks at the low position, but at the high position or once it shrinks, the stock price will break down and there will often be more room for decline.
Matters needing attention in using bollinger bands
1, the bollinger band parameter setting shall not be less than 6, and the static dry heave value is usually10; Dynamic money dragon is usually 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 cannot simply follow the principle of breaking the upper limit and buying the lower limit.
3. When the opening price narrows, it is easy to catch bull stocks at the low position, but at the high position or once it shrinks, 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.
Optimal parameter setting of bollinger bands
Investors study the recent trend, define an average of main support level or pressure, and then set up parallel channels for the main average according to this fluctuation range, which is the best channel index; At the same time, investors can set the standard deviation of the index to 15 according to their investment preferences, such as those who like short-term investment.
The method of setting bollinger band index parameters on mobile phone is as follows (taking straight flush as an example): First, enter the straight flush software. Then enter the stock K-chart interface, click the "..." option, and then click the setting option. Then click on the bollinger band indicator and enter a number in the standard deviation. Usually, the default quantity is 20.
The moving range of the stock price channel formed by the upper, middle and lower rails in the Bollinger Band Index is uncertain, and the upper and lower limits of the channel change with the fluctuation of the stock price. Generally speaking, the channel gradually closes, indicating that the stock trend is in the adjustment stage, while the channel diverges, indicating that the stock trend begins to choose a direction breakthrough.
