The index draw three lines in the figure, the two line can be respectively regarded as the pressure line of the stock price and the support line, and between the two lines and a stock price average, Bollinger index is the best parameter set to 20. In general, the stock price will run in the channels created by the pressure line and the support line. Here is mainly about predicting boll on the market, though, like KDJ, MACD and other indicators can be low to cross as a buy signal or by a high down cross as a sell signal, but these indexes have a disadvantage, when the stock price is the consolidation of the loss of function or cheat line and cause losses to investors. Usually in the process of stock price consolidation, what investors want to know most is that when the stock price will be consolidated, when will the market come into being?. Because if the stock is bought too early, and the stock does not rise again, the utilization of capital will be reduced, and the risk of stock price falling will be taken by investors. And Bollinger index can play its magic role at this moment, give the correct tips for the end of the consolidation, so that investors avoid buying stocks too early. Two, BOLL indicators of the general criteria for judgment (1) the significance of the upper, middle and lower three trajectories of the BOLL index 1, BOLL index in the upper, middle and lower track of the formation of the stock price channel movement range is uncertain, the channel's upper and lower limit with the fluctuation of the stock price fluctuation. Under normal circumstances, the stock price should always run in the stock price channel. If the stock price runs out of the stock price channel, it means that the market is in extreme state. 2, in the BOLL index, the upper and lower track of the stock price channel is the highest price and lowest price to show the safe operation of the stock price. The upper, middle and lower three tracks can play a supporting role in the operation of the stock price, while the upper trajectory and the middle trajectory sometimes play a role in the pressure of the stock price. 3, generally speaking, when the stock price runs above the middle line of the BOLL line, it shows that the stock price is in a strong trend; when the stock price moves downward in the middle trajectory of the BOLL line, it shows that the stock price is in a weak trend. (two) the relations among the upper, middle and lower three trajectories of the BOLL index 1, when the Bollinger line's upper, middle and lower trajectories run upward simultaneously, it shows that the strong characteristics of the stock price is very obvious, and the stock price will continue to rise in the short term, investors should firmly hold shares to buy up or buy on dips. 2, when the Bollinger line's upper, middle and lower tracks run downward simultaneously, it shows that the weak characteristics of the stock price are very obvious, and the stock price will continue to decline in the short term, and investors should firmly wait for the money or sell at higher prices. 3, when the upper line of the Bollinger line runs downward, while the middle trajectory and the lower trajectory are still running upward, it shows that the stock price is in the finishing posture. If the price is in the long-term upward trend, that price is a strong finishing way up, investors can buy short-term buying or holding wait-and-see; if the price is in the long-term downward trend, it is indicated that the stock price fell on the way to finishing the vulnerable, investors should be cautious or temper jiancang. 4, when the upper line of the Bollinger line runs upward, and the middle and lower trajectories run downward simultaneously, this possibility is very small. 5. When the upper, middle and lower orbits of Bollinger lines are running horizontally at the same time, it depends on what kind of situation the stock price is in. (1) when the lateral movement of the three line has been in a long time early stock market fell after the onset of Bollinger Bands, indicates the price is in the bottom of the building stage, investors can start small batches Jiancang, once the three line upward divergence may increase the buying efforts. (2) when the stock price is in a small rising market, the three lines of Bollinger line begin to move horizontally, which indicates that the stock price is in the rising stage, and the investors can hold the stock to be raised or bargain short term absorption, Once the three lines diverge upward, you can buy them in short term. (3) when the three horizontal lines begin shares have just experienced a market crash occurred after Bollinger moving stock show is in decline stage of finishing market, investors should be cautious and trim temper, once the three line downward resolutely went away. (4) the possibility of lateral motion of the three lines at the top of the Bollinger line is minimal. Three. The special analysis method of BOLL index The judgment of Bollinger line "bell mouth" is the unique judgment method of BOLL index. The so-called Bollinger "trumpet" refers to the process of stock price operation, special shape is similar to the bell on the trajectory and trajectory of Bollinger Bands respectively from two opposite directions and in orbit or close and the formation of a substantial expansion. According to the different trajectory and trajectory under the Bollinger running direction and position, we can also be divided into open type bell bell, bell and bell mouth tight shut type three types. (1) open bell horn Open type horn states often appear in the early market prices of stocks in the short term. There are two conditions for it: 1, the stock price to be low after a long time in finishing sideways, the longer the distance between the upper and lower rail is smaller, the greater the magnitude of the rise of the future; 2. When the Bollinger line starts to open, there will be obvious large volume. (two) closing bell type Early closing type horn states often appear in the stock market crash. The formation of the form although there is no requirement for the volume, but also must have a condition that the stock price after the early a try for short-term, try for the greater distance between the upper and lower rail is greater, the greater magnitude of future decline. (three) tight mouthed bell horn Tight mouthed bell forms appeared at the end of the stock market crash. The formation condition and confirm the standard is relatively loose, after a long time as long as prices fell sharply after the turnover withering, when the distance between the upper and lower trajectory can be found more and more small bell formed tight mouth. When the bell mouth appears, investors can wait for, can also be a small position. Four, BOLL indicators of actual combat skills The practical skills of BOLL index are mainly from the signal of sale and purchase and the signal of holding coins. (I) trading signals 1, the stock k bring rail to break up the Bollinger Bands, and the TRIX index has issued a low MACD, indicating the stock will enter a long-term rising channel, it is a buy signal issued by the BOLL index. At this point, investors should buy stocks in time. 2, when Bollinger rail after a long time low narrow horizontal movement, once the trajectory with the amount of K shares to break up the Bollinger Bands, and Bollinger channel suddenly had a narrow opening upwards, that stock prices coming from the original level of running channel into the rise of the new channel. This is a buy signal, BOLL index. 3, when the stock k line break down of Bollinger Bands in orbit, and the TRIX index also issued a "high Sicha", shows that the share price will enter a downward path for a long period of time, it is a sell signal BOLL index. At this point, investors should be cleared out as soon as possible. 4, when Bollinger rail after a long time of high narrow horizontal movement, line break down once the stock k Bollinger, and Bollinger channel had a narrow opening down suddenly, that stock prices coming from the original level of sports channel and dropped into the channel of the new signal, send this to sell is the BOLL index. (two) holding currency holding signal 1, when Bollinger opening up, as long as the price is always running in the top of the rail line Bollinger Bands, indicating the stock has been in a long-term rising channel, this is the BOLL index issued by holding up the signal, if the TRIX index is a holding signal, this signal is more accurate. At this point, investors should firmly hold shares to rise. 2, when Bollinger opening down, as long as the price is always running under the rail line love Bollinger Bands, shows that the share price has been in a long-term decline in the channel, this is the cash holding index issued by the BOLL signal, if the TRIX index is a hold signal, this signal is more accurate. At this point, investors should resolutely hold on to the currency. Five. Conclusion The stock market is unpredictable and ups and downs. The stock price is not up to you to avoid losing control, but is also not a bad idea. In fact, as long as the election of the stock, grasp the indicators, big money is not a dream, I'm afraid you do not do! First, stock selection requires good basic stocks, Second, choose the stocks of future growing companies. Third, on the K-line chart, the stock price is best to stand on the 30, 20, 10 and 5 day moving average. Fourth, to see the current stock location, choose the best price at a relatively low stock, for those in high sideways or down way sideways stock is best not to participate in. Fifth, the correct use of various technical indicators.
