MACD is a technical analysis indicator and an important tool for analyzing trends in investment fields such as stocks and futures. MACD consists of a set of indicator lines, of which yellow and white lines are two. The yellow line refers to the short-term moving average and the white line refers to the long-term moving average. When the yellow line intersects with the white line, it represents the change of buying and selling power, thus providing an important buying and selling signal. When the yellow line breaks through the white line from below, it shows that the upward trend of stock price is accelerating; When the yellow line breaks through the white line from above, it shows that the downward trend of stock price is accelerating. Therefore, the yellow and white lines of MACD are very important analysis tools.

MACD indicator consists of moving average and columnar line. The moving average line is used to show the traditional trend, and the bar line is used to show the change of trading signals. The color change of the columnar line is related to the position relationship between the yellow line and the white line, which is one of the important basis for judging the trading signal. If the yellow line and white line are at a high level, the red bar indicates that the stock price is already at a high level, and the buying and selling signal is selling; If the yellow line and the white line are at a low level, the green bar indicates that the stock price is already at a low level, and the buying and selling signal is buy. Therefore, in technical analysis, the yellow and white lines of MACD are also important indicators to judge the timing of buying and selling.

MACD indicators can be used to analyze different financial products and are widely used in stock, futures and foreign exchange markets. Whether it is short-term trading or long-term investment, the yellow line and white line of MACD can provide a strong analytical basis. When the trading signals provided by the yellow and white lines coincide with other indicators, the signals are more reliable. However, the indicators of MACD are also flawed. For example, it is difficult to adapt to the rapidly changing market, and it needs to be used together with other indicators to provide a more comprehensive analysis conclusion. When using MACD indicators, investors need to operate according to their own actual situation on the basis of strictly controlling risks.
