MACD indicator is a familiar analytical tool for most investors in the market. However, in the specific application, investors may feel that there are many gaps in the accuracy, effectiveness and operability of the use of MACD indicators. Sometimes, they will find that using the analytical methods and skills of MACD indicators learned in books to judge the trend of crude oil, the conclusions drawn are often quite different from the actual trend, and may even lead to the opposite results. The main reason for this situation is that the discussion on MACD in the market is mostly limited to the superficial level, and only introduces the general analysis principles and methods of MACD, but rarely involves some specific connotations and analysis skills of MACD analysis indicators. On the basis of introducing the general judgment skills and analysis methods of MACD indicators, the author will elaborate the special judgment principles and functions of MACD in detail. The general criteria for judging MACD indicators are mainly around the fast and slow moving averages, red and green bars and their shapes. The general analysis methods mainly include DIF and MACD values and their positions, the intersection of DIF and MACD, and the contraction of red columns.

First, the value and position of DIF and MACD line

1. When both DIF and MACD are greater than 0 (that is, graphically above the zero line) and move upward, it generally indicates that the oil price is in a bull market and you can buy or hold positions;

2. When both DIF and MACD are less than 0 (that is, graphically below the zero line) and move down, it generally means that oil prices are in a short market and can be sold or wait and see.

3. When both DIF and MACD are greater than 0 (that is, graphically above the zero line) but both move downward, it generally means that the crude oil market is in a low tide stage, and the oil price will fall, so it can be sold and waited;

4. When both DIF and MACD are less than 0 (that is, graphically below the zero line) but move upward, it generally means that the market is about to start, oil prices will rise, and you can buy or hold positions and wait for the rise.

Second, the intersection of DIF and MACD.

1. When both DIF and MACD are above the zero line, DIF breaks through MACD upward, indicating that crude oil is in a strong position and oil prices will rise again, so it is possible to overweight buying or holding positions, which is a form of MACD indicator "golden cross".

2. When both DIF and MACD are below the zero line, DIF breaks through MACD upward, indicating that the oil market is about to strengthen, and the oil price decline has stopped falling upward, so you can start buying or holding positions. This is another form of MACD indicator "golden cross".

3. When both DIF and MACD are above the zero line, but DIF breaks through MACD downward, it indicates that the oil market will soon turn from strong to weak, and the oil price will plummet. At this time, most positions should be sold rather than bought, which is a form of "death cross" of MACD indicator.

4. When both DIF and MACD are below the zero line, DIF breaks through MACD downward, indicating that the oil market will once again enter an extremely weak market, and the oil price will fall, so you can sell it or wait and see. This is another form of MACD indicator "death cross".

Third, the histogram analysis of MACD indicators

In crude oil online chart, the histogram is usually drawn by subtracting DEA (MACD, DEM) value from DIF value, which is represented by red column and green column, with red column representing positive value and green column representing negative value. Red and green columns are intuitive and practical to analyze the market.

1. When the red column continues to enlarge, it indicates that the oil market is in a bull market and oil prices will continue to rise. At this time, you should hold a position until the red column can no longer be enlarged, and then consider selling it.

2. When the green column continues to enlarge, it shows that the oil market is in a bear market and oil prices will continue to fall. At this time, you should wait and see or sell with money, and only consider buying in small quantities until the green column begins to shrink.

3. When the red column begins to shrink, it indicates that the bull market in the oil market is coming to an end (or will enter an adjustment period) and the oil price will drop sharply. At this time, most positions should be sold rather than bought.

4. When the green column begins to shrink, it indicates that the plunge in the oil market is coming to an end and the oil price will stop falling upward (or enter consolidation). At this time, a small number of long-term strategic positions can be opened instead of being sold easily.

5. When the red column begins to disappear and the green column begins to release, it is one of the signals that the oil market turns to the market, which indicates that the rising market (or high consolidation market) of the oil market is coming to an end and the oil price will begin to accelerate its decline. At this time, it is necessary to start selling most positions instead of buying.

6. When the green column begins to disappear and the red column begins to release, it is also one of the signals that the oil market turns to the market, indicating that the decline (or low consolidation) of the oil market has ended and the oil price will begin to accelerate. At this time, it is necessary to start overweight buying or rising positions.

The KDJ index, also known as stochastics, was first proposed by Dr. George Lane. This is a very novel and practical technical analysis index. It was first used in the analysis of futures market, and then widely used in the short-term trend analysis of stock market. It is the most commonly used technical analysis tool in futures and stock markets.

1) In practice, some short-term customers, who are short, flat and quick, often use the minute indicator to judge the market outlook and decide the trading opportunity. In T+0 era, 15 minutes and 30 minutes KDJ indicators are commonly used, and in T+ 1 era, 30 minutes and 60 minutes KDJ are used to guide entry and exit. Several rules of thumb are summarized as follows:

A) If the KDJ is consolidating below 20 for a long time in 30 minutes, so is the KDJ in 60 minutes. Once the K value crosses the D value and crosses 20 in 30 minutes, it may trigger an upward trend lasting for more than 2 days; If the daily KDJ indicator is also at a low level, it may be an intermediate market. However, it should be noted that it is only effective when the K value is greater than 20% of the D value after the intersection of the K value and the D value.

B) If KDJ turns head down above 80 in 30 minutes, and K is below D, it will fall below 80 minutes, and KDJ just crosses 20 in 60 minutes, less than 50, indicating that the market will turn head back, and KDJ may continue to rise after bottoming out in 30 minutes;

C) If the KDJ is above 80 in 30 minutes and 60 minutes, and the K value crosses the D value at the same time after a long period of consolidation, it indicates that it is necessary to start the downward adjustment of the market for at least 2 days;

D) If the KDJ falls below 20 in 30 minutes and turns upward, and the KDJ is still above 50 in 60 minutes, it is necessary to observe whether the K value will effectively cross the D value within 60 minutes (the K value is more than 20% of the D value), and if it is effective, start a new round of upswing; If it is invalid, it means that it is only a rebound in the process of falling, and it will continue to fall after the rebound;

E) If KDJ stops falling before 50 in 30 minutes, and KDJ just crosses upward in 60 minutes, it means that the market may continue to rise again, and it is only retreating at present;

F) KDJ deviates in 30 minutes or 60 minutes, which can also be used as a basis for judging the top and bottom of the market. For details, please refer to the previous discussion on daily deviation;

G) In the super-strong market, the KDJ can reach more than 90 in 30 minutes, and the high position repeatedly appears invalid crossover. At this time, we should focus on the 60-minute KDJ. When KDJ crosses down in 60 minutes, it may lead to a short-term deep retreat;

H) During the plunge, KDJ can approach 0 in 30 minutes, but the general trend is still declining. At this time, we should also look at KDJ in 60 Minutes. When KDJ effectively crosses within 60 minutes, it will trigger a strong rebound.

2) When the market is in a very strong and weak unilateral market, the daily KDJ is repeatedly passivated, and the medium and long-term indicators such as MACD should be used instead; When the stock price fluctuates greatly in the short term and the daily KDJ response lags behind, CCI, ROC and other indicators should be used instead; Or use SLOWKD slow indicator;

3) The weekly KDJ parameter is generally 5, and the weekly KDJ index has obvious prompting effect on bottoming and peaking. Accordingly, band operation can save a lot of hard work and strive for maximum profit. Need to be reminded that the weekly J value generally rises at the V-shaped single bottom in the oversold area, indicating that it is only a rebound market, and the formation of a double bottom is a reliable intermediate market; However, the J value may drop sharply at the top of the overbought area. At this time, we should be vigilant and judge comprehensively with other indicators. However, when the stock market is in a bull market, the stock price will still rise sharply after the J value is overbought for a period of time.
