In general technical analysis software, the fixed 30-minute MACD parameters are still12,26,9. That is, the fast EMV parameter is12; The slow EMV parameter is 26; The DIF parameter is 9.

The MACD index set according to this set of parameters can't bring great value to users in the 30-minute K-line, mainly because operating according to the operation signal given by this index often misses the best operation opportunity or loses future opportunities.

In fact, after repeated trial and error verification, the author found that the 30-minute K-line MACD index composed of parameter groups 6, 30 and 3 has high reference value in determining the buying and selling price.

As far as MACD and its parameters are concerned, we still have to emphasize several application principles:

First, the 30-minute MACD indicator can only be used as a reference signal for short-term trading points and cannot be used to judge the price trend for a long time to come. In other words, you can only use this indicator as a reference if you make a plan to buy or sell tickets and put it into practice.

And whether you decide to buy or sell tickets depends on the signal sent by the daily K-line or weekly K-line indicator system.

Secondly, like the principle of MACD application in other time periods, we can think that the higher or lower the value on the ordinate of the indicator, the less likely the indicator will encounter the crossover (failed crossover), and the greater the effectiveness of the crossover.

Therefore, we can take action before the indicators have crossed or may encounter crossing.

3. Different from the application principle of MACD indicator of daily K-line or weekly K-line, the MACD indicator in the price 30-minute K-line does not emphasize the deviation phenomenon-unless this deviation lasts for a long time, it should generally not be considered.

You only need to care about the intersection of DIF line and MACD line to carry out trading operations. There is a simple reason. The time period of 30-minute K-line is very short, so the deviation phenomenon often produces false signals.

Fourthly, other application principles we emphasized when discussing MACD indicators of daily K-line or weekly K-line are still applicable.

MACD indicator parameter setting: The parameters of the H 1(60 (60min) K-line MACD indicator in most analysis software are set to 12, 26, 9, that is, the fast EMA parameter is set to 12, the slow EMV index is set to 26, and the DIF parameter is set to 9. From the practical point of view, the MACD index formed by this group of parameters is not good enough, and it has obvious lag for the fluctuation of price trend, which can neither give users the first time to operate nor provide forecasting signals for the future price trend.

So what is the appropriate parameter value? Through trial and error, the author concludes that the price H 1(60 minutes) K line has two sets of MACD indicators, and the parameter values have high practical value, namely, fast EMA value of 6, slow EMV value of 30 and DIF value of 6; The fast moving average value is 6, the slow EMV value is 30 and the DIF value is 9.

The MACD indicators set by these two groups of parameter values have obvious performance improvement in terms of sensitivity to price changes and early warning of future price changes, as well as according to time span.

(note that it is not a cycle). Compared with the difference between stock and spot, the accuracy between the two will be improved, and it can be used as another analysis tool in the hands of users.

Macd indicator is the most common indicator, and many investors are familiar with its calculation principle, usage, advantages and disadvantages. So what is the best MACD parameter setting? As some textbooks say, the main defect of MACD is that it is too slow to respond to changes in price trends and cannot provide useful hints for short-term trends. So what can be done to change the situation that the MACD indicator is too slow? According to my own experience, the author thinks that this defect can be made up to some extent by changing the speed EMA parameter of the index.

There are two ways to set MACD index parameters, and the first method will be discussed in this issue. The author thinks that setting the fast EMV parameter to 15 and the slow EMA parameter to 90 is a better setting method.

We analyzed the Shanghai Composite Index and found that it failed to rise on May 8 this year, but fell sharply. If we look at the MACD with these two parameters set, the index actually has a dead fork between the DIF line and the MACD line as early as April 25th, while the red column line disappears and the green column line appears, showing a bearish trend. Of course, what is more obvious is that after last year's 5. 19 market, the index rose and fell around June 30. At this time, it is impossible to judge whether the market is a strong adjustment or the market is over. Only on July 7, when the MACD indicator is dead at a high level, can it be judged as bearish. It will be distributed at this time, with a space of about 260 points from the lowest point when the market fell later.

For the setting of this parameter, the author summarizes some experiences for readers' reference:

1. As far as individual stocks are concerned, the values of DIF line and MACD line marked on the vertical axis of MACD are very important. Generally speaking, the dead fork of MACD indicator at high level is often effective. The high position of this parameter is above+1.5, and some super-strong stocks can reach the range of 3 to 6. As long as the dead fork appears in these ranges, the price can often be bearish in the middle line, during which there will generally be a rebound, but there is no new market.

Second, as far as individual stocks are concerned, the effective interval of the golden intersection of the MACD indicator DIF and the MACD line should be below -0.45 on the vertical axis, otherwise it is of little significance, but the trend of some super-strong stocks may be an exception, which needs to be comprehensively judged by other indicators.

3. Generally speaking, when the DIF line and MACD line continue to climb up, away from the red column line, the red column line continues to shrink or even the green column line appears, we should be alert to the high-level dead fork of the indicator and the turning point of the price trend.

Four, with special emphasis on the use of deviation as an indicator. When the price continues to rise and hit a new high, the MACD indicator fails to touch the previous high point, which means that the price may fall back at any time; The upward force is not strong. Similarly, we can also summarize the situation when prices continue to fall.

The death of this indicator is issued before the price falls, and the golden cross is generally issued after the price rises.

Six, the judgment of some oversold stocks should be based on the average system (55 days, 120 days, 250 days).
