1.MACD, also known as exponential smooth average, is developed from double exponential moving average. The meaning of MACD is basically the same as that of double exponential moving average, but it is easier to read. When MACD turns from negative to positive, it is a buy signal. When MACD turns from positive to negative, it is a signal to sell. When the MACD changes at a large angle, it means that the gap between the fast moving average and the slow moving average expands very quickly, which represents the change of the market trend.

2. In most futures technical analysis software, columnar lines are colored, green below axis 0 and red above axis 0. The former indicates a downward trend, while the latter indicates an upward trend. The longer the column line, the stronger the trend.

1. When the DIF and DEA are above the 0 axis, it belongs to a bull market.

2. When the DIF and DEA are below the 0-axis, it is a short market.

3. Contraction and enlargement of columnar lines.

2. Form and deviation.

5. Cowhide market indicators will be distorted.

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. After practice, exploration and summary, the accuracy is greatly improved by comprehensively using 5-day, 10 moving average, 5-day, 10 moving average and MACD.

6. When the MACD and the trigger line are both positive, that is, above the 0 axis, it means that the megatrend is still in the bull market and the trend line is upward. At this time, the columnar vertical line extends from the 0 axis, and you can buy boldly.

7. When both MACD and trigger line are negative, that is, below the 0 axis, it means that the megatrend is still in the short market and the trend line is downward. At this time, the columnar vertical patterns start from the axis 0 and are below the central axis 0, and they extend below the axis 0. It should be sold at once at this time.

8. When MACD deviates from the trend of K-line chart, it should be regarded as a signal that the stock price is about to reverse, and we must pay attention to the intraday trend.

As far as its advantages are concerned, MACD can automatically define whether the stock price trend is too much or too short, thus avoiding the danger of reverse operation. After determining the trend, an access policy can be established to avoid unnecessary access times or inappropriate access timing. Although MACD is suitable for judging the medium-term trend, it is not suitable for short-term operation. Furthermore, MACD can be used to judge the beginning and end of the mid-term rising or falling market, but it is of no value to the box-shaped large oscillation trend or the glued disk surface. In the same way, when analyzing the trend of each stock with MACD, it is more suitable for investment stocks that have plummeted, but not for so-called cowhide stocks with little price change. In short, the function of MACD is to find out the overbought selling point of the market from the inflection point of the market.
