ROCPVI[Version No. 1]

ROCPVI stands for (rate of change price Volatility index). The ROCPVI metric effectively shows the rate of change in the PVI metric that was previously posted.

When the PVI index goes up, the amplitude of the price increases, and before that, the ROCPVI goes up.
Note that the elevation interval of the PVI indicator is slightly easier to capture.

As the oscillator of the MACD in the ROCPVI rises, the PVI's indicators rise and the amplitude of the price rises can be effectively captured.

Conversely, if the oscillator of the ROCPVI's MACD falls, then it is possible to effectively capture the segment where the indicators of the PVI fall and the price decreases in amplitude.

ROCPVI Fall = PVI Fall = The Amplitude of Price is Weak> Constant
ROCPVI rising=PVI rising=PVI decreasing amplitude of price> strong rise and fall interval

The ROCPVI indicator is a synthesis of the PVI and the build-in indicator, macd.
