Smma (MACD)—— MACD consists of positive and negative difference (DIF) and difference average line (DEA). Of course, the positive and negative difference is the core and DEA is the auxiliary. DIF is the difference between fast smma and slow smma. The difference between fast and slow is that exponential smoothing uses different parameters, fast is short-term and slow is long-term. Taking common parameters 12 and 26 as examples, the calculation process of DIF is: today's EMA (12) = 2/(12+1) × today's closing price+11(/kloc) Today's moving average (26) = 2/(26+ 1) × today's closing price +25/(26+ 1) × yesterday's moving average (26); The above two formulas are exponential smoothing formulas with smoothing factors of 2/ 13 and 2/27 respectively. You can use this method if you choose other coefficients. DIF = moving average (12)- moving average (26).DEA is the moving average of DIF, that is, the arithmetic average of DIF for several consecutive days. In addition, there is an index called BAR in the analysis software. BAR=2×(DIF-DEA). 1. KDJ's calculation of today's closing price-the lowest price for n days today (n) RSV = (—————————— )×100; The highest price in n days-the lowest price in n days today (n) K value = 2/3 yesterday k value+1/3 today (n) RSV; Today's (n) D value = 2/3 yesterday's D value+1/3 today's (n) K value; Today (n) J value = 3 Today (n) D value -2 Today (n) K value. The initial values of k and d are 50. Second, the principle of KDJ 1, KDJ takes today's closing price (that is, the final sum price of both sides in N days) as the balance point of purchasing power and efforts. The price distance from the closing price to the lowest price represents the purchasing power, and the price distance from the highest price to the lowest price represents the total purchasing power. In this way, the ratio of the purchasing power of RSV to the total power is used to represent the ratio of the purchasing power of the market since N days, reflecting the long and short situation of the market. 2. Later, the reviser of KDJ index gave up taking RSV as the k value directly, and only took RSV as the content of 1/3 in the new k value. This is a method of weight processing, which shows that more attention is paid to the role of (2/3) recent trends. 3. In George Lane's invention, the value of d was originally the smooth average of the value of k in n days. It can be seen directly from the formula that the value of d only takes the value of k as the weight of 1/3, which also shows the importance attached to the recent trend. At the same time, the change rate of D value is less than that of K value, so K line becomes a sensitive fast line in random indicators, while D line is a relatively stable slow line. 4. The original intention of J value is the deviation between D value and K value, and the coefficients 3 and 2 also show the treatment of weight value, which shows that D index should be paid more attention to in KD index, which is consistent with the guiding principle that slow line is more trending in trend analysis. Third, the application of KDJ 1 Generally speaking, the D line from the bottom to the top is a buy signal, and from the top to the bottom is a sell signal. 2.KD fluctuates in the range of 0 ~ 100, and 50 is the long-short balance line. If it is a multi-party market, 50 is the back support line; If you are in the empty market, 50 is the pressure line for rebound. 3. The K-line crosses the D-line at the low position as a buying signal, and the K-line crosses the D-line at the high position as a selling signal. 4. The overbought area is when the K line enters more than 90, and the overbought area is below 10; Line D is overbought when it enters above 80, and it is overbought when it enters below 20. Pay attention to the timing of buying and selling 5. The M-shaped trend of the D-line in the high-grade area is a common top shape. When the second head appears, when the K-line crosses the D-line for the second time, it is a sell signal. The W-shaped trend of D-line in low-level areas is a common bottom shape. When the second bottom appears, when the K-line crosses the D-line for the second time, it is a buy signal. When the M-shaped or W-shaped second part appears, if it deviates from the price trend, it is called "top deviation" and "bottom deviation" respectively, and the trading signal is highly reliable. 6. The value of j can be greater than 100 or less than 0. The J-index provides a credible judgment on whether actions can be taken according to KD trading signals. Generally, when the value of j is greater than 100 or less than 10, it is considered as the opportunity to take trading action. 7.KDJ is essentially a random fluctuation index, so the value of n in the calculation formula is usually small, and it is appropriate to take 5 to 14, which can be selected according to the characteristics of the market or goods. However, applying KDJ to weekly or monthly lines can also be used as a tool for medium and long-term forecasting. Weekly KDJ-a sharp weapon for band operation For investors who like to do band market, weekly KDJ indicator is a sharp weapon. The application points are as follows: 1. The J line in the middle of the week is ignored by many people, and it is the most sensitive and accurate response to the stock price, so we should pay full attention to it. 1, when the weekly J-line is below 0 and the Xing Xing K-line closes, the goddess of opportunity will come and you can buy in batches. This is especially true in a bull market where the stock price runs above the 60-week moving average. 2. In the short market where the stock price runs below the 60-week moving average, the weekly J line is often passivated below zero. Don't take buying action immediately at this time, wait patiently for the Zhou J line to be hooked up, and then buy after receiving the Zhou Yang line. 3. When the hook head falls below 100 on the weekly J line and the K line closes, death appears. Be alert to the appearance of tops and lose weight first. This is especially true in the short market where the stock price runs below the 60-week moving average. 4. In a bull market where the stock price runs above the 60-week moving average, the weekly K line is often passivated above 100. Don't take selling action immediately at this time, wait patiently for the weekly J line to go down, and then take selling action after collecting the weekly K line. Second, when the J line in the weekly KDJ goes below 0 and crosses the weekly KD line, there will be a wave of intermediate market. If the daily KDJ is also a gold fork at this time, it is necessary to buy decisively. If the daily KDJ is dead, you need to wait for the daily KDJ to adjust downwards, and then intervene after the golden fork to avoid short-term lock-up. After the weekly J line crosses the weekly KD line below 0, the weekly D line will generally rise above 100, and the strong market will be ammoniated above 100. There will also be a weekly K-line, which is only an adjustment in the rising market. This feature of Zhou J line provides a quantitative basis for judging the appearance of the top of Shenzhen-Shanghai band. Thirdly, after the J line in the weekly KDJ drops above 100 and crosses the weekly KDJ line, there will be a wave of intermediate adjustment. If the daily KDJ is also at a high level at this time, it is necessary to sell decisively. If the daily KDJ gold fork is only a short-term rebound, then it should be decisively sold when the daily KDJ is also dead. After the weekly K line falls above 100 and crosses the weekly KD line, the weekly K line generally falls below 0, and the weak market will not be passivated below 0. In the meantime, there will be Xing Xing K-line, which is just a rebound in the falling market. This feature of Zhou J line provides a quantitative basis for judging the appearance of the bottom of Shenzhen-Shanghai band. This method is mainly suitable for short-selling market. Fourthly, KD in weekly KDJ is an absolute buy signal after retrogression at the bottom of two lines of KD. The rising trend of weekly KD line after bottom deviation is stronger than that after oversold without bottom deviation. This situation has only happened four times in Shanghai since 1996, and the signal is reliable. When applying weekly KBJ, remember that the rebound of serious oversold will make the bottom go backwards. 5. When applying weekly KDJ, we should also combine monthly KDJ, and properly handle four relationships: 1, weekly KDJ and monthly KDJ*** are great promotion opportunities, so we should seize them. 2. When the monthly KDJ gold fork and the weekly KDJ dead fork, you should leave in principle and buy again at the weekly KDJ gold fork. 3. The monthly KDJ dead fork and the weekly KDJ gold fork belong to a strong rebound and can be properly intervened. 4. When the monthly line KDJ and the weekly line KDJ die, they should leave and wait for new opportunities. When both k and d are below 10, there is a chance of short-term rise or even skyrocketing. However, it should be noted that: (1) Sometimes when the K and D indexes are lower than 10, it will only appear for one day, and sometimes it will appear for several days in a row. Pay attention to buying. However, because both K and D are below 10, which is a rare extreme situation, it generally means that the stock price has fallen too much, and the short position is a spent force. It can lead to short-term technical schools copying chassis, which will bring gains. (2) It is still necessary to pay attention to: if there are exceptions, you should set a stop loss and prepare for failure; And it does not apply to stocks whose fundamentals have changed dramatically and deteriorated extremely. For example, in the continuous daily limit of 10 in Yinguangxia in 2006, it was 5438+0, and now it is 6548+0.19989.666 When K and D are lower than 10, we can't immediately bargain-bottom, so we need to consider them comprehensively according to the fundamentals of individual stocks. (3) From the scanned stocks whose K and D are lower than 10, most examples are: both K and D are lower than 10, which leads to a short-term rise or even a skyrocketing share price, with a high proportion. The summary of the above situation belongs to the statistical category. It can't be regarded as a law, but it is suitable for a high probability situation. And the situation that both k and d are below 10 needs careful people to catch. In most cases, both k and d can hardly be lower than 10. The above opportunities have elements that can not be met. But once encountered, the opportunity belongs only to the prepared mind.
