MACD, invented by Gerald Appel and called moving average convergence bifurcation, is one of the simplest and most reliable indicators. MACD uses lagging moving average indicators to show trend characteristics. When the short moving average is subtracted from the long moving average, these lagging indicators become momentum oscillators. In this way, it constructs an oscillation line that swings up and down on the zero line, and there is no limit to the up and down amplitude.

MACD formula

The most commonly used standard MACD is the difference between the 26-day and 12-day exponential moving averages. This is used by many technical analysis programs. Appel and others also tried to adopt other settings to adapt to faster or slower price changes. For example, using a relatively short moving average can produce faster and more sensitive fingers.

Mark; Using a long moving average can produce a relatively slow indicator, which is not easy to respond to short-distance fluctuations. In this article, we will use 12/26MACD to illustrate.

Of the two moving averages that make up MACD, the moving average on 12 is the fast line, and the moving average on 26 is the slow line. Both EMAs are calculated at the closing price. Usually, we will use the 9-day moving average to cover MACD as the trigger line. When MACD crosses the 9-day moving average and stands above it, it is a bull market signal; On the contrary, after the MACD is staggered, there is a bear market signal below the EMA line on the 9 th. In the following Merrill Lynch stock chart, the green line is 12 EMA and the blue line is 26 EMA, covering the price chart. MACD is displayed in the chart below the price chart, which is a thick black line; At the same time, mixed with the 9-day moving average, it is a thin blue line. The histogram represents the difference between MACD and 9-day moving average. When MACD is higher than the 9-day moving average, the bar line is positive, otherwise it is negative.

MACD is based on smma of two indices with different speeds to calculate the deviation between them as the basis of market judgment. In fact, it is to use the signs of convergence and separation of fast and slow moving averages to judge the timing and signal of buying and selling. In practice, the MACD indicator not only has the functions of bargain hunting (when the price deviates from the MACD) and capturing the strong rising point (when the MACD turns red for the second time in a row), but also captures the best selling point to help investors escape from the top successfully. Common ways to escape from the roof are:

1, the stock price is sideways, and the MACD indicator is sold dead. It means that the stock price has been sideways after a sharp rise, forming a relatively high point, and the MACD indicator is the first to appear dead fork. Even if there is no dead fork on the 5 th and the 10 moving average, it is necessary to lighten up the position in time.

2. If the stock price does not plummet after the MACD indicator is dead, but rises again after the callback, it is often the last time the main force rises to cover the shipment, and the height is extremely limited. The high point formed at this time is often the highest point of a wave of market. The sign at the top of the judgment is the deviation of "price and MACD", that is, when the stock price hits a new high, but the MACD fails to hit a new high at the same time, the two trends deviate, which is a reliable signal that the stock price peaks.

A detailed description of the use of MACD indicators

MACD is the abbreviation of convergence and divergence of moving average, which is translated into identical and different smooth moving average in Chinese. It mainly uses long-term and short-term smooth average lines to calculate the difference between them as the basis for judging market transactions.

Algorithm:

Difference between short-term and long-term smma of DIFF line closing price.

M-day index smma of DEA line difference line

The DIFFerence between MACD line diff line and DEA line, color column line

Parameters: SHORT (short), LONG (long), m days, generally12,26,9.

Usage:

1.DIFF and DEA are both positive numbers, and DIFF breaks through DEA and buys the signal.

2.DIFF and DEA are both negative numbers. DIFF falls below DEA and sells the signal.

3. number three. DEA line deviates from k line, and the market reverses signal.

4. analyze the MACD column line, turn positive to negative, and sell the signal; From negative to positive, buy signal.

MACD application article number 1:

MACD indicator is a trend indicator based on the construction principle of moving average, which smoothes the closing price of the price (calculates the arithmetic average). It mainly consists of positive and negative difference (DIF) and difference average (DEA), in which positive and negative difference is the core and DEA is the auxiliary. DIF is the difference between fast smma (EMA 1) and slow smma (EMA2).

In the existing technical analysis software, the commonly used parameters of MACD are fast smma 12 and slow smma 26. In addition, MACD has an auxiliary indicator bar. In most technical analysis softwares, columnar lines are colored, green below axis 0 and red above axis 0. The former represents weakness, while the latter represents strength.

Let's talk about the basic principles that should be followed when using MACD indicators:

1. When the DIF and DEA are above the 0 axis, it is a bull market, and when the DIF line crosses the DEA line from bottom to top, it is a buy signal. When the DIF line crosses the DEA line from top to bottom, if the two lines are still running above the 0 axis, it can only be regarded as a short-term decline, and the trend inflection point cannot be determined. Whether to sell or not at this time needs to be judged by combining other indicators.

2. When the DIF and DEA are below the 0 axis, it is a short market. When the DIF line crosses the DEA line from top to bottom, it is a sell signal. When the DIF line crosses the DEA line from bottom to top, if the two lines are still running below the 0-axis, it can only be regarded as a short-term rebound, but the inflection point of the trend cannot be determined. At this time, whether to buy or not needs to be judged by combining other indicators.

3. Columnar line contraction and amplification. Generally speaking, the continuous contraction of columnar lines indicates that the strength of trend operation is gradually weakening. When the color of the column line changes, the trend determines the turning point. However, when using some short-term MACD indicators, this view cannot be fully established.

4. Form and deviation. MACD indicators also emphasize morphology and deviation. When the DIF line and MACD line of MACD indicators form a high bearish pattern, such as head and shoulders, double heads, etc. We should be vigilant; When the morphological MACD indicator DIF line and MACD line form a low bullish pattern, you should consider buying. When judging the shape, DIF line is the main one and MACD line is the auxiliary one. When the price continues to rise and MACD indicators come out one after another, it means that the top deviation appears, indicating that the price may turn around in the near future. When the price continues to fall, but MACD indicators come out one after another, it means that the bottom deviation appears, indicating that the price is about to end the decline and turn to rise. (See the improvement of MACD practical application skills below)

5. The index of cowhide market will be distorted. When the price does not run from top to bottom or from bottom to top, but keeps running horizontally, we call it cowhide market. At this time, a false signal will be generated in the MACD indicator, and the intersection of the DIF line and the MACD line will be very frequent. At the same time, the retraction of column lines will occur frequently, and the color will often turn from green to red or from red to green. At this point, the MACD indicator is in a distorted state, and its use value will be reduced accordingly.

Among many technical indicators, MACD is one of the simple and practical indicators, which is more suitable for small and medium-sized investors who are new to the stock market and want to master certain technical indicators. Let me talk about the application rules of MACD first:

1. Use the values of DIF and DEA and their relative values to forecast the market.

(1) When both DIF and DEA are positive, it belongs to a bull market. When DIF breaks through DEA, it is a buy signal, and when DIF falls below DEA, it can only be considered as a retracement. (2) When both DIF and DEA are negative, it is a short market. DIF's downward breakthrough in DEA is a selling signal, while DIF's upward breakthrough can only be considered as a rebound.

The curve shape of DIF is used for analysis, mainly using the deviation principle of indicators. Specifically: if the trend of DIF deviates from the trend of stock price, it is time to take concrete action.

However, the accuracy of guiding the actual operation according to the above principles is not satisfactory. Comprehensive use of 5-day, 10 moving average, 5-day, 10 moving average and MACD greatly improves its accuracy.

After a long period of decline, (1) stock price began to bottom out, and then it began to slowly pick up. 5-day 10 moving average The 5-day 10 moving average and MACD all show a golden cross, referred to as the golden cross. This time is the signal that the stock price has bottomed out. The more intersections, the higher the bottom and the higher the accuracy. For example, 0933 Shenhuo Co., Ltd., on October 5, 2000 10, the stock's moving averages on the 5th and 10, and the bottom of the moving averages and MACD on the 5th and 10 at the same time, that is, the golden fork, was the best time to intervene, and then the stock showed a strong upward trend. Within three months,

(2) When the stock price rose sharply and was sought after by many small and medium-sized investors, the main force began to distribute. At this time, the 5 th and 10 moving averages appear, and the 5 th and 10 moving averages and MACD are dead at the same time, which is the best time to sell. At this time, with a little hesitation, the stock price will plummet. For example, on March 9, 2000, 0722 Jinguo Industrial issued a strong selling signal due to the appearance of the "three dead forks", and then its share price plummeted, from 27. 17 yuan to 13.46 yuan in just two months, with an amazing drop. After the main force fled, it was followed by a continuous decline.

MACD Application No.2:

In stock market investment, MACD indicator, as a technical analysis method, has been recognized by investors. However, few people know how to use MACD index to make the investment income reach the best level. As a tool of stock market investment analysis, technical analysis has two major functions. The first is to find investment opportunities in the stock market, and the second is to protect the investment income of the stock market from losses. In the operation of the stock market, MACD indicators play a far greater role in protecting the interests of investors than in finding investment opportunities. As a medium-and long-term analysis method, MACD indicator produces cross signals that lag behind short-term transactions. MACD indicator is a general trend indicator, which consists of five parts: long-term moving average MACD, short-term moving average DIF, red energy column (bulls), green energy column (bears) and 0 axis (long-short boundary). It uses the intersection of short-term moving average DIF and long-term moving average MACD as the signal. The cross signal generated by MACD indicator is slow, but it is effective as a corresponding trading strategy. The specific use method is as follows:

1 when DIF MACD MACD are above the 0 axis, it means that the general trend is in a bull market, and investors should take the shareholding as the main strategy.

If DIF crosses MACD from bottom to top, it doesn't mean it is a buy signal. At this time, the market trend is already a short-term high point, and the strategy of selling high and sucking low should be adopted. Under normal circumstances, there will be a low callback on the second or third day after the cross signal is generated, and then you can buy again to achieve the purpose of sharing the cost. If DIF crosses MACD from top to bottom, it means that the rising market in this band has ended. Usually after the cross signal is generated, there will be a decent rebound, and the formation of the short-term top has been confirmed. At this point, investors can take the opportunity to close their positions. In the subsequent adjustment, the stochastic indicator KDJ and the strength indicator KSI are used to wait for the opportunity to intervene to reduce the operating costs. If DIF crosses MACD for the second time from bottom to top, it indicates that there will be a strong upward trend. After the cross signal is generated, investors should hold shares all the way until DIF crosses MACD from top to bottom again, and then clear all the stocks, so they can take their wallets home to rest. Due to the diversity of the stock market, MACD indicators often deviate from the K-line chart, which is often called bear deviation. Not only did the K-line chart hit the second or third high point in the near future, but the MACD indicator did not have a corresponding high point. Instead, it showed the opposite trend, and the peak value was gradually decreasing. The phenomenon of seed separation should arouse the vigilance of investors, because it indicates that the market will plummet in the future, and investors should adopt the strategy of clearing the warehouse and leaving the market to avoid being caught in the quilt and causing financial losses.

When the DIF and MACD are below the 0-axis, it shows that the current trend belongs to the short market, and investors should wait and see mainly by holding money.

If DIF crosses MACD from top to bottom, there will be an adjustment low point. Under normal circumstances, this is followed by a wave of rebound, which is a good opportunity for investors to close their positions. In China stock market, there is no short-selling mechanism at present, so once the stock market enters the short-selling market, investors' best strategy is to leave the market and wait and see. Investors can increase the value of their funds when the stock depreciates. If DIF crosses MACD from bottom to top, it will produce a recent high point, and investors should decisively close their positions. The generation of such signals is generally rebound in nature. In the short market, every rebound should be regarded as the best time to ship. In particular, if DIF crosses MACD from top to bottom for the second time, it indicates that there will be a big decline in the future. After the cross signal is generated, investors should resolutely clear their positions. Usually there will be a decline in this period, which belongs to the C wave decline in wave theory and is the most lethal one. Only by avoiding the decline of C wave can we really make money in the stock market. After the C-wave decline in the short market, the MACD indicator occasionally deviates from the K-line chart, which is usually called long divergence. Even if the K-line chart has a second or third recent low, the MACD indicator has no corresponding low, but the bottom is higher than the bottom. This phenomenon indicates that the market will reverse in the future, and investors should actively intervene because the current market is completely risk-free.

3 When MACD indicator is used as a separate system, short-term can refer to DIF trend.

If DIF falls from top to bottom and crosses the O-axis, it can be seen that the general trend may enter a short market, which indicates that the general trend will weaken and should arouse investors' vigilance. In the short-term market, investors bear more risks than returns. If MACD falls from the top to the empty O-axis, confirm that the general trend has entered the short market. Investors should adopt a wait-and-see strategy to avoid market risks and ensure the profits earned in the bull market. If the DIF crosses the O-axis from bottom to top, it can be seen that the megatrend may spread into a bull market. It indicates that the general trend will be stronger, and some funds will be involved in the operation. If MACD crosses the O-axis from bottom to top, it is confirmed that the general trend has entered a bull market. Investors can boldly hold shares and actively intervene. In a bull market, the benefits outweigh the risks.

4 In the MACD indicator, the red energy column and the green energy column represent the strength of bulls and bears respectively. Their response to the market is ahead of the short-term moving average DIF. In MACD index, the process of energy release is a gradual process, usually gradually enlarged. Oriental philosophy emphasizes that "yang is abundant, yin is abundant, and it is strong". When using the energy column, the conclusion is that when the K-line graph rises nearly 90 degrees, coupled with the rapid amplification of the red energy column, it shows that the top of the general trend is near. Especially when two adjacent red energy columns are connected, the market will be more rapid. On the contrary, in the short market, this phenomenon is also true. Now I am familiar with it.

5. In the process of using MACD indicators, there are two points to pay attention to.

First of all, MACD indicators are not necessarily reliable for judging the short-term top and bottom. Only by combining the medium-term deviation rate with the ADR index in the static money dragon can we judge.

Second, it is better to use weekly MACD index analysis than daily MACD index analysis.

In short, when using MACD indicators, we must determine the attributes of the market. That is, whether the current market is bull market or short market. According to different market attributes, different operation strategies are adopted to avoid risks and ensure profits. In specific operations, the golden cross of MACD is generally an important buying opportunity. First, according to the analysis of its main points, when the DIF and MACD lines are below the 0-axis and far away, they turn from descending to leveling, and the golden fork formed by the slow line MACD on the fast DIF is a good short-term buying opportunity, but it must be noted that the judgment of the distance between DIF and MACD is mainly based on historical records. The gold fork that appears above the 0 axis cannot be too far away from the 0 axis. Otherwise, its reliability will be greatly reduced. It is more inclined to connect the red columns in the red ocean into a region, and the DIF crosses the MACD forward above the 0 axis to form a golden cross, in which the line reliability is better. At the same time, it is also in line with the stock market. There are many opportunities in the strong market, and it is difficult for the weak market to make money.

===================================================================================================

Improve the practical application skills of MACD;

1: In actual use, investors may find it difficult to make a profit by buying and selling gold forks completely or may lock in losses. Therefore, it is suggested that you can use a low-level double gold fork buying method. When MACD crossed the low level for the first time, the stock price rose in a limited way in many cases, or there was a big correction after a small increase, which caused the investors who bought it to suffer losses. However, when MACD appears at a low level for the second time, the probability and magnitude of stock price rise will be greater. Because after the indicator crossed the golden fork for the first time, there was a small callback, forming a dead fork. At this time, the empty side seemed to take the initiative again, but in fact it was a spent force. Therefore, when the indicator crossed the golden fork for the second time, it would inevitably lead to the upward attack of various forces.

█▉[b] The parameters are set to fast ema 12 and slow ema26.

How to use:

When the stock price rises, the macd turns red, that is, the white line crosses the yellow line (don't buy it yet). Then, when the stock price falls, the dif (white line) moves closer to the macd (yellow line). When the white line and the yellow line are bonded (to turn green but not green), it is only necessary to cooperate with the daily K line at this time. At this time, the K-line has an ending signal, such as the Yang Cross. Note: When white and yellow are bonded, we should start to observe the market. If you can stop falling at this time, it is called "bottom deviation". Bottom deviation is the best time to buy! !

Examples can be given at will, and there are countless stocks at the bottom. For example, 60077 1 Dongsheng Technology on May 26th, 2004, 60049 1 Long Yuan Construction on July 28th, 2004, 00039 Zhong Yi Group on July 30th, 2004 and so on.

On the other hand, when the stock price falls back at a high level, macd turns green and rebounds again. At this point, when dif (white line) and macd (yellow line) are bonded, if it is blocked, such as closing the cross star, it may be the last selling opportunity! ! ! At this time, many people think that they will regain their upward trend and buy at other people's best selling points. There are also many examples, and netizens can grasp them themselves.

But in the operation should pay attention to:

A. whether to break through the front high (low) position or not is ignored when swinging back.

B. At a high position, as long as there is a top deviation, it is generally possible to sell, and it will turn red again without hitting, unless it is sunny or daily limit.

C. It is an excellent means to find short-term trading points. The short-term range is above 15%, but the mid-line trend should be combined with the long-term pattern.

2. The actual combat experience correction of MACD

First of all, it is suggested that the life cycle of MACD must be reduced to time-sharing K-line.

MACD itself is mainly chasing trends, and it is a medium-and long-term indicator. According to the daily operation of MACD, this requires excellent psychological quality. It is observed that most investors can't bear huge fluctuations in capital rights and interests for several consecutive trading days. Therefore, according to the daily cycle of MACD, the operation cost of investors is obviously increased, which makes the original heavy psychological burden of investors more overloaded. The key is that the MACD of the daily cycle fluctuates very slowly, and it is often too late to send out a signal after the market has undergone earth-shaking changes. At this time, intervention will lead to a sharp drop in investors' profits. In fact, MACD can be simplified as time-sharing K-line. As for the time-sharing MACD of 5, 15, 30 and 60 minutes, you can refer to the exponential period resonance for comprehensive use, or investors can choose the time-sharing period they are good at. In the futures market, MACD is an effective time-sharing K-line.

Secondly, we should make full use of the top-bottom deviation signal of MACD.

This is the most obvious warning signal in the market, and it is difficult to be manipulated artificially (because MACD is a trend chasing tool, some investment forces often cannot fool the top-bottom deviation signal).

3. Pay attention to the "peak" and "valley" of MACD in actual combat.

1. In the bullish trend, DIFF goes down through DEA, forming a "peak". Every time you encounter this situation, you must see clearly: compared with the previous "peak", the position of this "peak" is getting higher or lower, and the corresponding K-line trend is getting bigger or smaller.

If the trend of K-line rises gradually, several "peaks" also rise steadily at the same time. At this point, investors can hold long positions with peace of mind, and wait until the K-line price effectively falls below the important support of the ordinary moving average before all positions are closed. It should be pointed out that the risk of shorting investors has become extremely great at this time, and it is impossible to short the band against the trend at this time.

The key point is that if the K-line trend gradually rises, but suddenly there is a "peak" opposite to it and keeps falling, it forms the top deviation between the K-line trend and the MACD "peak". At this point, investors should immediately start to gradually close their positions and leave. This situation often means that the bulls are mainly pulling the boat, and the price increase is often a superficial illusion.

2. In the short-term trend, DIFF crosses DEA upward, forming a "bottom". Similarly, every time we encounter this situation, we must see clearly: compared with the previous "bottom" position, it is high or low, and the corresponding K-line trend is gradually increasing or decreasing.

If the K-line trend gradually declines, several "valleys" also slowly decline at the same time, and the K-line trend deviates from the MACD valley bottom. At this time, investors must resolutely hold short positions, unless the K-line price effectively breaks through the important pressure of the ordinary moving average, and then all positions are closed. At this time, it is extremely risky to be a multi-investor, and it is impossible to carry out band long-term operation against the trend.

It must be noted that if the K-line trend gradually decreases and suddenly rises continuously to the "bottom", investors should consider starting to gradually close their positions and leave. This situation often means that the main short sellers are shipping in the pressure plate, and the price drop is deceptive.

In short, MACD is the best "companion" to use EMA, and investors should use it more in market trends. The specific usage varies with different varieties and market conditions, so it should be used flexibly.

4.MACD Bottom Backstepping Buying Method

There are two cases of MACD bottom deviation: one is the peak bottom deviation of negative (green) column, and the other is the bottom deviation of two curves.

(1) negative (green column peak) bottom reverse push buying method.

First, the negative (green) column peak one-time bottoming buy-back method.

Features: Only two negative column peaks have bottom divergence. This is a credible short-term buying signal. When the bottom of the two negative column peaks deviates, the buying opportunity can adopt the "double two" buying method, that is, when the second negative column peak has a second shrinking green column line, it can be bought at a lower price.

Example ①: Shantui Co., Ltd. (000680), on June 22, 2003, the bottom of Yinzhu peak slipped back (compared with the low Yinzhu peak on June 22, 2002), and the second shrinking green column line appeared on the second Yinzhu peak on June 28, 2003. Example 2: Guiliugong (000528), on June 24, 2003, there was a negative column peak-bottom deviation (two peaks were connected with the bottom deviation), and on June 26, a second shrinking green column line appeared at the second negative column peak. On that day, the average price was 10 yuan, and the band was adjusted to buy at a low level.

B, negative (green) column peak double bottom buy back method.

This is a reliable buying signal, and there are two bottoms falling at the peak of MACD negative column. Buying time: when the first or second shrinking green column line appears at the peak of the third negative column.

Example 1: Deep House (000029). On June 5, 2002, the Yinzhu peak appeared twice. On June 6th, the first shrinking green column line appeared at the third negative column peak, which was bought at an average price of 7.60 yuan and sold at an average price of 1 1.90 yuan on June 25th, earning 4.30 yuan per share. Example 2: Longteng Technology (600058), the second bottom deviation occurred at Yinzhu Peak on June 5, 2002. It was bought at an average price of 13.20 yuan on that day and sold at an average price of 15.40 yuan on June 24, earning 2.20 yuan per share and making a profit of1/kloc-0.

C. negative column peak compound bottom reverse push buying method.

Characteristics: After the first negative column peak, the third negative column peak has no negative column peak and the second negative column peak has a negative column peak, which is called "peak-to-peak divergence". This is a credible buying signal. Buying time: when the first or second shrinking green column line appears at the peak of the third negative column.

Example ①: Quanxing Co., Ltd. (600779), on May 14, 2003, the negative column peak showed a compound bottom deviation (compared with the negative column peaks on March 20, 2003 and April 9, 2003), and the first shrinking green column line appeared on the third negative column peak on May 15, based on the average price of the day. Example 2: BOE (000725), negative column peak compound bottom cycle appeared in May 13, and the third negative column peak appeared in May 16. The second shrinking green column line was bought at the average price of 9. 13, and in June 13.

(2) When the negative column peak and MACD curve deviate from each other at the same time, the buying signal is reliable and you can actively buy.

Example: Sino-technology trade (600056). On June 6th, 2003, the peak value of negative column and MACD curve deviated from the bottom at the same time, which triggered a strong rising market. At the beginning of June 5438+ 10, 2003, a number of stocks in Shenzhen and Shanghai both showed negative column peaks and MACD curves, and these stocks all performed well in the first half of 2003.

③ There are two bottom slip or compound bottom slip on ③③MACD curve, and the probability of middle and long-term bottom is greater.

The negative column peak of ④④MACD and the bottom deviation of the two curves mostly appear when the stock price runs below the 60-day moving average. A strong market where the stock price runs above the 60-day moving average rarely appears, and once it appears, you can actively buy it.

5.MACD hyperbola "fast gold fork after dead fork" buying method

The method needs to meet the following conditions:

MACD hyperbola dead fork will cross again within 3 trading days. This situation shows that the main washing is very fierce, deliberately creating the illusion of MACD dead fork, which will make the unstable out, and the market outlook will help the main force to pull up. Buying time: when MACD curves cross again and there is a heavy volume positive line on that day.

6. Flexible use of "bottom finder" to find the real bottom.

This paper introduces a method of combining MACD and 30-day moving average to find the bottom, which can eliminate most invalid signals and leave the truest and purest buying signals. How to use it: In the MACD indicator, the DIF line crossed the MACD line below the 0-axis and did not rise above the 0-axis, but quickly crossed the MACD line again. At this time, investors can wait for the two lines to cross gold again. If the two lines cross gold again (below the 0-axis), the 30-day moving average will also turn upward, indicating that the bottom construction is successful, and there is a greater possibility of a wave of market.

Example 1: Since Ningxia Hengli (600 165) went public, there have been two such signals, and there was a big market after each appearance. For the first time, the stock price kept falling from 1998 10/65438+in October to 165438+ in/999. The second time: since 1999 165438+ 10/8, there have been three DIF lines and MACD lines under axis 0, and the 30-day moving average has maintained a downward trend, indicating that the bottom has not been bottomed successfully. The last golden fork was on June 65438+1October 20, 2000 and June 65438+1October 24, 30. The more times the MACD line crosses the golden fork and the dead fork below the 0-axis, the longer it takes for the stock to bottom out, and the wider the space once it turns upside down.

Example 2: For example, Chuantou Holdings (600674) started to build a downtrend channel from1June 1999. During this period, the MACD line and DIF crossed the zero axis seven times, but failed to reverse the callback trend, and the 30-day moving average also maintained a downward trend. The last golden fork appeared on June 265438+1October 2 1. On the 30th of the same day, I turned upside down and closed my eyes. It can be seen that the MACD indicator and the 30-day moving average are like "detectors" at the bottom. When they are combined, no matter where they are hidden, they can easily detect the "true bottom".
