In many investors' watching habits, BOLL indicators may still be used less. More people are used to the KDJ and MACD set in the system, and then look at the market by combining the trading volume and the moving average. The following is Bian Xiao's 30-minute tactics for the bollinger Band. For reference only, I hope to help everyone.
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.
Three major buying points of Brin line
Boll indicator draws three lines on the map, in which the upper and lower lines can be regarded as the pressure line and the support line of the stock price respectively, and there is an average line of the stock price between the two lines, and the parameter of Bollinger Band indicator is preferably set to 20. Generally speaking, the stock price will run in the channel formed by the pressure line and the support line.
Use of Boll indicator
Among the three major buying points of the bollinger band, when the bollinger band is in the form of an open mouth and the middle rail is in a continuous state, for example, the middle rail is continuously opened upwards, which means that the stock price has started to rise after adjustment. At this time, we can buy in the short term, and the middle track primary election begins to level off or even go down. This is our selling point.
When the upper and lower rails of the Bollinger Band start to move closer, the stock price will also rise and fall. When necking occurs, the middle trajectory is very important. If the middle rail is in a continuous upward state, it means that the current stock price is adjusting or the main force is washing dishes. At this point, the bollinger band begins to flatten, and there will be buying points, while the middle rail will reverse from rising to flattening. Once necking happens, that's our selling point.
After a round of ups and downs, the stock price entered the final stage. When the stock price rises, Brin turns around with the upper rail, and the KDJ indicator or MACD indicator appears dead fork, which represents the selling point. And if the stock price reverses in the process of falling, and the KDJ indicator or MACD indicator has a golden cross, that is our buying point.
How about the combination of Boll indicator and MACD? MACD indicator is a technical indicator used by investors in foreign exchange speculation. The key problem of MACD indicator is crossover and deviation. Therefore, when using the bollinger band, it depends on whether it is a golden fork or a dead fork. At the same time, it is the most basic condition for the exchange rate to run above the middle rail of BOLL line. If the BOLL line is flat and the rail width is narrowed, it is best.
Use of BOLL indicator
Boll index is to calculate the "standard deviation" of the stock price, and then find the "trust interval" of the stock price. The indicator has drawn three lines on the map, in which the upper and lower lines can be regarded as the pressure line and the support line of the stock price respectively, and there is an average line of the stock price between the two lines, and the parameter of the Bollinger Band indicator is preferably set to 20. Generally speaking, the stock price will run in the channel formed by the pressure line and the support line.
BOLL indicator function: bollinger bands can indicate support and pressure positions; Bollinger bands can show overbought and oversold; Bollinger bands can indicate trends; The bollinger band acts as a channel. Bollinger bands are very effective and convenient to use because of their multiple functions. Once mastered, the signal is clear and flexible to use, which is loved by professional investors. They are also one of the most commonly used technical indicators in the international financial market.
Usage within the normal range
The normal range is usually that the stock price runs in a certain width band, which shows that the stock price is in a relatively balanced state and there will be no extreme ups and downs. At this time, the use of bollinger bands is very simple.
1. When the stock price crosses the upper pressure line (dynamic upper pressure line, static upper pressure line BOLB 1), sell the signal.
2. When the stock price crosses the lower support line (dynamic lower support line, static lowest support line BOLB4), buy some signals.
3. When the stock price crosses the middle boundary from bottom to top (from BOLB4 to BOLB3 statically), it is an overweight signal.
4. When the stock price crosses the middle boundary from top to bottom (BOLBI statically crosses BOLB2), it is a sell signal.
In a strong market, the stock price keeps rising, usually running between BOLB 1 and BOLB2. When the stock price keeps rising for a long time, it will wear BOLB 1 at the meeting, and then it will wear BOLB 1 at the meeting the next day, which will further break through BOLB2 and drive the BOLB 1 curve, and there will be an obvious inflection point from rising to leveling. This is the selling signal.
