Volume Weighted Volitility MACD

Volume Weighted Volatility MACD is inspired by the concept mentioned in a paper on volume weighted volatility , implementing MACD on top of it helps gauge the variation in "activity" which can be interpreted as a leading momentum indicator, it cycles from trending : hist>0 to corrective movement : hist < 0 .
This is my first published script !
I need help testing the capabilities of this indicator.
Looking forward to your reviews!
