Principle and calculation method of KDJ index
First, the principle of KDJ index
The stochastic indicator KDJ generally calculates the immature random value RSV of the last calculation period through the highest price, the lowest price and the closing price of the last calculation period in a specific period (usually 9 days, 9 weeks, etc.). ) and the proportional relationship between them, and then calculate the K value, D value and J value according to smma method, and draw a graph to judge the stock trend.
Random indicator KDJ is a point formed by calculating the highest price, lowest price and closing price, and connecting the obtained K value, D value and J value with countless such points to form a complete KDJ indicator that can reflect the price fluctuation trend. It is a technical tool that mainly uses the real amplitude of price fluctuation to reflect the strength of price trend and the phenomenon of overbought and oversold, and sends out buying and selling signals before the price rises or falls. In the design process, the relationship between the highest price, the lowest price and the closing price is mainly studied, and some advantages of the concept of momentum, power index and moving average are also integrated, so the market can be judged quickly, quickly and intuitively.
Stochastics KDJ first appeared in the form of KD index, which was developed on the basis of William index. However, William indicator only judges the overbought and oversold phenomenon of stocks, while KDJ indicator combines the concept of moving average speed to form a more accurate basis for buying and selling signals. In practice, K-line and D-line cooperate with J-line to form KDJ index. Because KDJ line is essentially a concept of random fluctuation, it is more accurate to grasp the short-term trend of the market.
Second, the calculation method of KDJ index
The calculation of KDJ index is very complicated. First of all, we have to calculate the RSV value of the period (n days, n weeks, etc. ), that is, the immature random index value, and then calculate the K value, D value, J value, etc. Taking the calculation of daily KDJ value as an example, the calculation formula is as follows
Rsv = (cn-ln) in n days? (Hn-Ln)？ 100
In the formula, Cn is the closing price on the nth day; Ln is the lowest price in n days; Hn is the highest price for n days. RSV value is always 1? Fluctuating between 65438 and 000.
Secondly, calculate the values of k and d:
K value of the day =2/3? K value of the previous day+1/3? RSV today
D value of the day =2/3? D value of the previous day+1/3? K value of the day
If there is no K value and D value of the previous day, you can use 50 instead.
Take the KD line with a period of 9 days as an example. First, the RSV value of the last 9 days, that is, the immature random value, must be calculated. The formula is RSV = (c-L9)? (H9-L9)？ 100
Where c is the closing price on the 9th day; L9 is the lowest price in 9 days; H9 is the highest price in 9 days.
K value =2/3? K value of the previous day+1/3? RSV today
D value =2/3? K value of the previous day+1/3? RSV today
If there is no K value and D value of the previous day, you can use 50 instead.
It should be noted that the smoothing factors 1/3 and 2/3 in the formula can be selected artificially, but they have been fixed as 1/3 and 2/3 by convention at present. In most stock market analysis softwares, the smoothing factor has been set to 1/3 and 2/3, and there is no need to change it. In addition, KD is usually introduced together with the J index.
The formula for calculating the J index is:
J=3D？ 2K
In fact, the essence of J is to reflect the deviation degree of K value and D value, so as to find the head or bottom before KD value. The range of j value can exceed 100.
J indicator is an auxiliary indicator. The earliest KDJ indicator had only two lines, namely K line and D line, also called KD indicator. With the development of stock market analysis technology, KD index has gradually evolved into KDJ index, thus improving the ability of KDJ index to analyze the market. In addition, in some important stock market analysis software, the K, D and J parameters of KDJ index have been simplified to only one, that is, the number of cycles (such as days, weeks and months). ). And with the development of stock market software analysis technology, investors only need to master the basic principles and calculation methods of KDJ formation, and do not need to calculate the values of K, D and J, and more importantly, use KDJ index to analyze and judge the stock market.
Like other indicators, due to different calculation periods, KDJ indicators include daily KDJ indicators, weekly KDJ indicators, monthly KDJ indicators, annual KDJ indicators and minute KDJ indicators. Daily KDJ index and weekly KDJ index are often used in stock market research. Although their calculated values are different, the basic calculation method is the same.
General criteria for judging KDJ indicators
The stochastic indicator KDJ mainly analyzes the phenomena of overbought and oversold, trend deviation and mutual breakthrough of K-line, D-line and J-line in the stock market through the graphic relationship of K-line, D-line and J-line, so as to predict the medium, short-term and long-term trends of stock prices. KDJ is an analytical tool familiar to most investors in the market. However, when using it, investors may find that there is a big difference between the analysis results of KDJ and the actual trend, and sometimes they will come to the opposite conclusion. The main reason is that most investors only know the general analysis principles and methods of KDJ, but know little about some connotations and specific analysis skills of KDJ analysis indicators. This section introduces the common judgment skills and analysis methods of KDJ in stock market analysis, focuses on the internal laws of KDJ indicators, and analyzes some special judgment functions of KDJ in detail.
KDJ index is three curves, and the general criteria for judging KDJ index in application are mainly from six aspects: the values of three parameters of KDJ, the shape of KDJ curve, the intersection of KDJ curve, the deviation of KDJ curve, the running state of K line, D line and J line, and the cooperation between KDJ curve and stock price curve.
First, the value of KDJ
1, value range
In the KDJ index, the range of values of k and d is 0? 100, and the range of j value can exceed 100 and be lower than 0, but the range of KDJ judgment in analysis software is 0? 100。 Generally speaking, in terms of sensitivity, J value is the strongest, followed by K value and D value is the slowest, while in terms of safety, J value is the worst, followed by K value and D value is the most stable.
2, overbought oversold signal
According to the value of KDJ, it can be divided into several areas, namely overbought area, oversold area and wandering area. According to the general classification standard, three values of K, D and J below 20 are oversold areas and buy signals; If the values of K, D and J are above 80, it is an overbought area and a selling signal; What are the values of k, d and j at the age of 20? 80 is a wandering area, so we should wait and see.
3. Comparison of long and short forces
Generally speaking, when the values of K, D and J are around 50, it shows that the strength of both sides is balanced; When k, d and j are all greater than 50, it shows that many forces are dominant; When the values of k, d and j are less than 50, it means that the air force is dominant.
Second, the form of KDJ curve
The judgment of KDJ index can also be analyzed from the shape of KDJ curve. When KDJ index curve forms head-shoulder top-bottom shape, double top-bottom shape (that is, M head and W bottom) and triple top-bottom shape, it can also be analyzed according to the judgment method of morphological theory. Various forms of KDJ curve are an analytical method to judge the market trend and decide the trading opportunity. In addition, KDJ indicator curve can also draw trend line, pressure line and support line.
1. When the KDJ curve is at a high level above 50, if the trend of the KDJ curve forms a top reversal shape such as M-head or triple top, it may indicate that the stock price will turn from strong to weak, and the stock price will plummet, so the stock should be sold in time. If the curve of stock price also presents the same shape, it can be confirmed that its decline can be judged by the shape theory of M head or triple top.
2. When the KDJ curve is at a low level below 50, if the trend of the KDJ curve shows a bottom reversal pattern such as W bottom or triple bottom bottom, it may indicate that the stock price will turn from weak to strong, and the stock price will rebound upward soon, so it can absorb a small amount of stocks on dips. If the stock price curve also presents the same shape, it is more recognizable, and its increase can be judged by W-bottom or triple bottom's shape theory.
3. In the form of KDJ curve, the accuracy of M head and triple top is greater than that of W bottom and triple bottom.
Third, the intersection of KDJ curves.
The intersection of KDJ curves can be divided into two forms: golden intersection and dead intersection.
Generally speaking, during the complete rise and fall of a stock, the K-line, D-line and J-line in the KDJ index will appear twice or more? Golden cross? And then what? The cross of death? Situation.
1. When the stock price is consolidating at a low level for a long time, and the K, D and J lines are all below the 50 line, once the J line and the K line break through the D line almost at the same time, it indicates that the stock market is about to strengthen, and the stock price decline has ended and will stop falling upward. You can buy stocks and open positions in the medium and long term. This is the KDJ indicator? Golden cross? A form of.
2. When the stock price is in a consolidation state during a period of rising, and the K, D and J lines are hovering around the 50-line, once the J line and the K line break through the D line again almost at the same time, the trading volume will be released again, indicating that the stock market is in a strong position and the stock price will rise again. You can buy stocks, or you can hold shares up. This is the KDJ indicator? Golden cross? A form of.
3. When the previous stock price has risen for a long time, the stock price has risen sharply. Once the J-line and the K-line break through the D-line at a high level (above 80) almost at the same time, it indicates that the stock market will soon turn from strong to weak, and the stock price will plummet. At this time, most stocks should be sold, not bought. Is this the KDJ indicator? The cross of death? A form of.
4. When the stock price fell after a period of time, but it lacked the motivation to rebound upward, and various moving averages exerted strong pressure on the stock price, the KDJ curve briefly rebounded to the vicinity of the 80th line, but failed to return to the top of the 80th line. Once the J-line and K-line break through the D-line again, it indicates that the stock market will once again enter an extremely weak market, and the stock price will fall. You can sell the stock again or wait and see. This is the KDJ indicator? The cross of death? Another form.
Fourth, the deviation of KDJ curve.
The deviation of KDJ curve refers to when the trend direction of KDJ indicator graph is just opposite to that of K-line graph. There are two deviations of KDJ index: top deviation and bottom deviation.
When the trend of the stock on the K-line chart is higher than the other, the stock price keeps rising, while the trend of the KDJ indicator on the KDJ curve is lower than the other, which is called top deviation. The phenomenon of top deviation is generally a signal that the stock price will reverse at a high level, indicating that the stock price is about to fall in the short to medium term, which is a signal to sell.
When the trend of the stock on the K-line chart is lower than that on the K-line chart, the stock price is falling, while the trend of the KDJ indicator on the KDJ chart is higher than the bottom, which is called low deviation. Bottom deviation is generally a signal that the stock price will reverse at a low level, indicating that the stock price is about to rise in the short to medium term, which is a signal to buy.
Like other technical indicators, the top deviation is more accurate than the bottom deviation in KDJ deviation. When the stock price is at a high level and KDJ is above 80, it can be considered that the stock price is about to reverse downward and investors can sell the stock in time; When the stock price is at a low level and KDJ is also at a low level (below 50), it usually takes several times to deviate from the bottom to confirm that investors can only make strategic positions or short-term investments.
Verb (abbreviation of verb) The running state of K, D and J curves.
1. When the J curve begins to break through the K curve at the bottom (below 50), it indicates that the weak consolidation pattern of the stock price may be broken and the stock price will move up in the short term. Investors can consider a small number of long-term positions.
2. When the J-curve breaks through the K-curve and moves up quickly, and the curve also breaks through the D-curve, it shows that the medium and long-term stock price rise has begun, and investors can increase their efforts to buy stocks.
3. When the curves of K, D and J begin to get rid of the narrow consolidation range in the previous period and move up quickly, it shows that the stock price has entered a short-term strong pull-up market, and investors should firmly hold the stocks to be increased.
4. When the J curve starts to turn around at a high level (above 80) after rapid upward movement, it means that the stock price rises too fast in the short term and will start to adjust in the short term, so investors can sell stocks in the short term.
5. When the D curve also starts to turn down at a high level, it means that the short-term rise of the stock price may end, and investors should sell stocks in the middle line.
6. When the K-line also starts to turn down at a high level, it means that the short-and medium-term stock price rise has ended, and investors should all clear their positions and leave.
7. When the K, D and J curves move down from the high position at the same time, it shows that the downward trend of the stock price has been formed, and investors should resolutely hold the currency and wait and see.
6. Application of KDJ curve and stock price curve.
1. When the KDJ curve and the stock price curve rise synchronously from the low level (both KDJ values are below 50), it indicates that the medium-and long-term trend of the stock price is improving, and the stock price is expected to continue to rise in the short term. Investors should continue to hold shares or buy on dips.
2. When the KDJ curve and the stock price curve fall synchronously from the high level (both KDJ values are above 50), it indicates that the stock price will continue to decline in the short term, and investors should continue to wait and see or sell on rallies.
3. When the KDJ curve falls from a high level, it goes up again and hits a new high after a period of strong consolidation, and the stock price curve also goes up again and hits a new high after a strong consolidation at a high level, indicating that the upward momentum of the stock price is still strong, and investors can continue to hold stocks to be increased.
4. When the KDJ curve falls back from a high level and rises again after a period of consolidation, but it turns around near the previous high point and fails to hit a new high, while the stock price curve is still rising slowly and hitting a new high, the KDJ curve and the stock price curve form opposite trends at a high level, which may mean that the motivation for the stock price to rise begins to weaken, and the KDJ indicator appears to deviate from the top. At this time, investors should be careful. Once the stock price falls, they should leave decisively and quickly.
5. During the long-term weak decline, the KDJ curve bounced down again after a period of weak rebound and hit a new low, while the stock price curve also hit a new low after the weak consolidation, indicating that the downward momentum of the stock price is still strong, and investors can continue to wait and see.
6. When the KDJ curve bounces back from the low position to a certain high position and then falls back again, but it stops falling and stabilizes when it is pulled back to the previous low point and fails to hit a new low, while the stock price curve is still slowly falling and hitting a new low, the KDJ curve and the stock price curve form an opposite trend at the low position, which may mean that the kinetic energy of the stock price decline begins to weaken, and the KDJ indicator deviates from the bottom. At this time, investors should also pay close attention to the stock price trend. Once the stock price rises, they can buy for a short time and wait for a rebound.
Special analysis method of KDJ
First, the analysis cycle of KDJ
Day, week, month and minute (mainly 60 minutes)
The applicable period of KDJ for analysis parameters below 10 is about 3 days (from golden fork to dead fork is 3 days).
The service life of KDJ with analysis parameters less than 50 days is about 10 days.
The applicable period of KDJ with analysis parameters exceeding 50 days is about 20 days.
Second, the moving average priority principle
Once the stock price is suppressed by the long-term moving average, KDJ can only do short-term operations and never make medium-and long-term investments. This is the premise of using KDJ. In the long-term moving average, and away from the moving average, KDJ gold fork, the stock price may oversold and rebound, can do short-term operations.
Third, the general cycle of rebound.
Does the daily KDJ last at most 15 days in the short to medium term? 1 month
Weekly KDJ is a mid-term, lasting 1 month? 3 months (once the gold fork, it will basically rise within one month, but the increase is uncertain)
The monthly KDJ is long-term, and the maintenance time is usually 3 months? 5 months
Four, after the ex-rights, KDJ index is meaningless, and it will take at least three months to re-judge.
Modification of KDJ parameter of verb (abbreviation of verb)
With the wide application of technical analysis, the importance of technical indicators is self-evident. However, at present, the calculation of technical indicators has been greatly simplified, which leads to the similarity of technical indicators in a large area and loses its guiding role. Therefore, in order to keep the accuracy, sensitivity and timeliness as harmonious as possible, it is necessary to reset the parameters of some indicators, and pay attention to the following general rules:
First, set the parameters according to the time period. Regardless of the market or individual stocks, the time cycle will have a great impact on its operation, and the cycle itself is often a very important parameter, especially in the moving average, strength indicators and so on. As for the measurement of cycle, it can usually be determined by the time span of two important low points. At the same time, due to the difference between long, medium and short lines, investors must set personalized and familiar parameters according to specific conditions, and 5 (day) or its multiple and Fibonacci series are good choices in this respect.
Second, keep the consistency of different time standards. If the parameters suitable for the daily line are put into the time-sharing, especially the shock index will be too sensitive, and it will obviously lag behind when used for the weekly or monthly line. Therefore, in the process of application, this principle must be appropriately adapted before it can be used. This is by no means a simple calculation problem, but it needs to be fine-tuned after conversion. Although individual indicators are absolutely consistent, good results can still be achieved.
Third, pay attention to the similarities and differences between the market and individual stocks. Because the relationship between the market and individual stocks is both general and special, the same index parameter suitable for the market can usually be used for most stocks directly or after a little adjustment, but there are differences between them after all. The average result of the market often covers up a lot of truth or ignores personalization, that is, the stocks in the super-strong or ultra-weak state are different from the market, so the setting of their parameters should be different.
Fourth, constantly adjust and optimize as the market changes. Strong stocks and weak stocks are very different from the broader market, and the operation of balancing market and trend is also different. In the face of the rapidly changing market, once the original parameters are found to be unsuitable for the market situation at that time, everyone needs to modify the parameters to optimize the index. This should be a long-term work, especially the short-term and medium-term parameters.
Sixth, the judgment of KDJ index with different periodic parameters.
(1) Usage of 34 KDJ (note: this is the KDJ parameter on Qianlong software).
For most stock market analysis software, investors can modify the indicators according to different stocks, stock trends in different periods and investors' interest preferences, and thus draw different analysis conclusions. Change the daily value of KDJ to 34. Let's briefly introduce the usage of 34-day KDJ.
1. First of all, the range of KDJ operation is divided into extremely weak areas below 20, 20? 50 is a weak area, 50? The strong area between 80 and the extremely strong area above 80, and the value of 50 is the dividing line between strength and weakness.
On the 34 th, the 50-line in the KDJ indicator was a strong short-term resistance for the stock price to rise from a weak region. As long as the D value of KDJ does not effectively rush to the 50-bit value, it cannot be said that the stock price has gone out of the weak zone. It is normal for the two values of KD to fail at this point, so we must attach great importance to the role of this resistance level, and many stocks rebound at this point.
On the 34th, the 50-line in the KDJ index was relatively easy to break through. Although it had some support for the stock price to fall from a strong region, it had no important reference significance. This is the same reason that the stock price rises to match the volume, while the decline can be realized without the volume.
2. When the ternary value of KDJ runs in a very weak region below 20, it is generally not intended to buy, and it is mainly to wait and see with the currency, especially when the stock price has just experienced a long-term decline. have only
However, after the stock price plummeted and consolidated at a low level for a long time, if there is a low-volume big Yang line with reversal significance, or a K-line combination with reversal significance, investors are clearly told to enter the market.
3. When the three values of KDJ run above 80 in the extremely strong area, the selling plan is generally not made, and the increase is the main one. Unless there is a high volume negative line with reversal significance (dark clouds cover the top and the head is broken), or a K-line combination with reversal significance clearly tells investors to leave.
4. The longer 4.KDJ runs in the extremely weak area below 20, the more attention should be paid to the golden fork signal from the extremely weak area, especially those golden forks with large upward angle that can quickly leave the 20-line. The K-line combination also clearly tells us that there is a possibility of reversal, and we should pay more attention to the significance of this golden fork, which is likely to be the first signal formed at the bottom in the short and medium term.
5. The longer 5.KDJ runs in the extremely strong area above 80, the more attention should be paid to the dead fork signals sent by the extremely strong area, especially those dead forks that can quickly fall below the 80-line at a large downward angle. K-line morphological combination also clearly tells us that there is a possibility of reversal, so we should pay more attention to the significance of this dead fork, which is likely to be the first signal formed at the top.
6. Every time the KDJ gold fork is above 20 (weak area) and above 50 (strong area), it is an opportunity to intervene. The higher the position of the golden fork, the greater the market significance. At the same time, we must pay attention to the angle of KDJ golden fork. The bigger the angle, the better. In addition, we should also pay attention to the combination of K-line forms and the cooperation of trading volume. If the KDJ dead fork is seen shortly after the intervention of the high KDJ gold fork (above 80 lines), investors should immediately stop the loss and leave the market to prevent the loss from further expanding. However, if the gold fork below 20 has no KD value, it will quickly break away from the extremely weak area of 20 or confirm the reversal of the K-line combination, which has little market significance.
7. Every time KDJ falls below 80 (strong area) and below 50 (weak area), it is a signal that you must leave. The higher the dead fork value, the greater the downside risk. However, the dead fork of KDJ in the extremely weak area below 20, if the KD binary value does not continue to fall, has little reference significance.
8. Short-term stock price surge will lead to the lag of KDJ's continuous rise. At this time, we should keep calm and avoid blindly chasing up. At this time, the stock price trend may be opposite to that of KDJ, so wait patiently for the KDJ trend to run synchronously with the stock price trend. Then look for opportunities to intervene. Similarly, the short-term plunge of the stock price will also cause the lagging decline of KDJ, and the rebound trend of the stock price after the plunge will be opposite to that of KDJ. When the trend of KDJ is synchronized with the trend of stock price, it is time for us to rebound and leave.
9. In the falling market, the position of KDJ golden fork will be lower and lower when it rebounds, resulting in the position of KDJ dead fork becoming lower and lower. In the rising market, the position of KDJ dead fork will be higher and higher when it is called back, which leads to the higher and higher position of KDJ gold fork.
10, after KDJ rushes out of the extremely weak zone 20, KDJ will retaliate, that is, the stock price has not risen much, and KDJ will soon enter the strong zone. At this time, we should pay attention to the callback of KDJ and the second golden fork of KDJ in the strong area, because the second golden fork intervention will be more significant than the first one. There is still more room for growth.
The use of 1 1 and KDJ only exists as an auxiliary means. Investors should refer to the K-line combination of stock price, the relationship between volume and price, and the trend pattern, and make joint judgments with KDJ indicators. When their trading signals tend to be consistent, such trading signals are more reliable.
(2) How to use KDJ parameter in No.89 (Note: this is KDJ parameter in Qianlong software)
If the No.34 KDJ indicator is regarded as a short-term KDJ indicator with practical significance, then the No.89 KDJ indicator is an important KDJ mid-line indicator. Although it has many similarities with the 34th KDJ indicator, there are also many different steps. The specific judgment is as follows:
1, which is the same as the KDJ index on the 34th, and the KDJ operating range on the 89th is also divided into extremely weak areas below 20, with 20? 50 is a weak area, 50? The strong area between 80 and the extremely strong area above 80, and the value of 50 is the dividing line between strength and weakness.
On the 89 th, the 50-line in the KDJ indicator was a strong short-term resistance for the stock price to rise from a weak region. As long as the D value of KDJ does not effectively rush to the 50-bit value, it cannot be said that the stock price has gone out of the weak zone. It is very normal for KD value to fail at this point, so we must attach great importance to the role of this resistance level, and many stocks rebound at this point.
On the 89th, the 50-line in KDJ index was relatively easy to break through. Although it had some support for the stock price to fall back from the strong region, it had no important reference significance. This is the same reason that the stock price rises to match the volume, while the decline can be realized without the volume.
2. Pay attention to 0? KDJ in the 20-range, the closer to the bottom, the more the stock price rises. Like the KDJ indicator of No.34, the longer the KDJ of No.89 runs in the extremely weak area below 20, the more attention should be paid to the golden January issued by the extremely weak area, especially those golden forks with large upward angles that can quickly leave the 20-line. The K-line combination also clearly tells us that there is a possibility of reversal, so we should pay more attention to the significance of this golden fork, which is likely to be the first signal formed at the bottom of the medium and long term.
3. On August 9th, the top 80 dividing lines in KDJ indicators have great guiding significance for selling stocks in the middle line. As long as the 89KDJ curve does not break through the 80 range, you can hold shares all the way. Until the J-line, K-line and D-line in this indicator all fall below the 80-line defense line, all or most of the shares in the middle line can be sold.
The longer the K, D and J curves of KDJ run in the extremely strong area above 80, the more attention should be paid to their dead forks in the extremely strong area, especially those curves with large downward angles that can quickly fall below 80. K-line morphological combination also clearly tells us that there is a possibility of reversal, so we should pay more attention to the significance of this dead fork, which is likely to be the first signal formed at the top in the medium and long term.
5. When the KDJ indicator is stuck at a high level above 80 on the 89th and starts to diverge downwards, you should immediately sell the remaining stocks and don't buy stocks easily (you should wait and see when the dead fork diverges downwards).
6. Once the KDJ index is lower than 20, and it begins to diverge upwards on the 89th, don't sell stocks easily until it is determined to be dead at a high level.
(3) How to use KDJ for 55 weeks (Note: this is the KDJ parameter on Qianlong Software)
Compared with the 34th and 89th KDJ indicators, the 55th week KDJ indicator is a long-term indicator in the study of KDJ indicators, which has a strong reference significance for studying the trend of a stock in the next six months or longer.
1 and weekly K-line (55 weeks) KDJ are similar to daily K-line (34 days) KDJ.
First of all, like the daily KDJ index judgment, the weekly KDJ running range is divided into extremely weak areas below 20, 20? Between 50 is the weak area, 50? The area between 80 is a strong area, above 80 is a very strong area, and the 50-line is the dividing line between strength and weakness.
The 50-line in the weekly KDJ indicator is a strong resistance for the stock price to rise from the weak region. As long as the D value of KDJ does not effectively reach 50, it cannot be said that the stock price has gone out of the weak zone. It is normal for KD value to return to zero at this point, and the rebound of many stocks ends at this point.
The 50-line in the weekly KDJ indicator is a strong support level for the stock price to fall from a strong region. If the weekly KDJ indicator is supported near the 50-line, the medium-long line of the stock price is still optimistic, and once the KDJ curve falls below the 50-line again, it indicates that the medium-long line of the stock price is still not good.
2. The golden fork in any area with 2.KDJ below 80, the K-line shape and the strong turning point of J value supported by quantity and price are all signals of intervention position.
The lower the value of the gold fork, the greater the market significance. At the same time, we must pay attention to the angle of KDJ golden fork, the bigger the angle, the better. In addition, we must pay attention to the combination of K-line forms and the cooperation of trading volume. If we have a dead fork in KDJ after the intervention of KDJ Golden Fork, we should immediately stop and leave.
3, weekly K-line (55 weeks) KDJ's dead fork in the area above 50 and the J-value strong head when the K-line shape is broken are all stop-loss signals. The higher the dead fork value, the greater the downside risk.
4. When the weekly K-line (55 weeks) KDJ ternary value runs in the extremely weak area below 20, there is generally no need to make a buying plan, and it is the best policy to wait and see with the currency. Unless the low-volume Dayang line (a positive finger) has a reversal meaning, or the K-line combination has a reversal meaning, it clearly tells us to enter the market.
5. When the weekly K-line (55 weeks) KDJ ternary runs in the extremely strong area above 80, there is generally no need to make a selling plan, and holding shares is the best policy. Unless there is a high-level and heavy-duty negative line with reversal significance (the dark clouds cover the top and the head is broken), or the K-line combination with reversal significance clearly tells us to leave.
6. The short-term stock price surge will lead to the continuous rise of KDJ lagging behind, which is more obvious than the rise of KDJ on March 34. At this time, we should keep calm and avoid blindly chasing up. At this time, the stock price trend may be opposite to that of KDJ, so wait patiently for the KDJ trend to run synchronously with the stock price trend. Then look for opportunities to intervene. Similarly, the short-term plunge of the stock price will also cause the lagging decline of KDJ, and the rebound trend of the stock price after the plunge will be opposite to that of KDJ. When the trend of KDJ is synchronized with the trend of stock price, it is time for us to rebound and leave.
7. The higher the bit value of 7.KDJ dead fork, the greater the risk to the stock price. Similarly, the lower the value of KDJ gold fork, the more secure the stock price rise. In the falling market, the value of KDJ's golden fork will be lower and lower when it rebounds, which leads to the lower and lower value of KDJ's dead fork. In the rising market, the value of KDJ dead fork will be higher and higher when it is called back, which leads to the higher and higher value of KDJ gold fork.
8. After KDJ rushes out of the extremely weak area for 20 years, KDJ will have a retaliatory rise, that is, the share price will not increase much, and KDJ will soon enter the strong area. At this time, we should pay attention to the callback of KDJ and the second golden fork of KDJ in strong areas, because the intervention of the second golden fork will be more significant than every time, and there will be more room for growth.
9. The use of KDJ only exists as an auxiliary means, especially for the weekly K-line KDJ, the lag effect is more obvious. Don't blindly choose the entry and exit points according to the weekly K-line KDJ, but the weekly K-line KDJ also has its advantages, that is, its stability and the directivity of the medium and long-term trend are relatively clear.
