It has nothing to do with volume.

2.

Deviation requires two highs or two lows.

3.

If the first high point is caused by the rapid rise of prices, then you will also see the rapid rise of indicators.

4.

If the second highest point barely appears after repeated price shocks, it will be reflected in the indicators, and there will be a phenomenon that the indicators cannot follow the price to hit a new high.

5.

From the perspective of wave theory, the strong rise of the third wave will drive the indicators to rise at the same time, while the last wave after the fourth wave adjustment is due to the lack of motivation of price form, which leads to the inability to follow up despite hitting a new high.

6.

Macd has strong resistance to sudden price changes and relatively high reliability when deviating from the signal due to the adoption of quadratic smooth average algorithm.

I hope it helps you.
