1, the applicable indicators are different.

MA moving average is the main graph indicator, MACD indicator is the sub graph indicator, and EMA 1 and EMA2 are MACD indicators.

2. Different calculation methods.

MA is calculated by the arithmetic average of the closing prices of the last n trading days. EMA 1 and EMA2 are the fast and slow moving average lines in MACD index respectively. Taking these two values as the basis to measure the DIFference (DIF) between them (fast and slow lines), the smma DEA (also called MACD and DEM) lines with dif period of n can be found.

When applying MACD, the fast moving average (generally 12 days) and the slow moving average (generally 26 days) should be calculated first. These two values are used as the basis to measure the "difference" between the two (fast and slow lines). The so-called "DIF" is the average value of 12 minus the average value of 26.

Therefore, in the continuous upward trend, the average of 12 is above the average of 26. At the same time, the positive deviation (+DIF) will become larger and larger. On the contrary, in the downward trend, the deviation value may become negative (-DIF), and the absolute value becomes larger and larger.

The inversion signal of MACD is defined as the 9-day moving average (9-day moving average) of "deviation value". In the calculation formula of MACD moving average, the component weights of T+ 1 trading day are added respectively. Taking the commonly used parameters 12 and 26 as examples, the formula is as follows:

Firstly, the fast moving average (EMA 1) and slow moving average (EMA2) are calculated, and these two figures are used as the basis to measure the difference (DIF) between them. Then, the smma DEA (also called MACD, DEM) line of DIF n period is calculated.
