Percent Change Smoothed (PCT + EMA)
ROC works great on data with only positive numbers (like prices).
But it fails to correctly represent the rate of change when source series have negative values.
ROC is positive when:
Percent change (PCT) is just a ROC that deals with this sign confusion.
Anyone with Data Science backgroud would likely know about it.
PCT is positive only when:
When applying to only positive data PCT = ROC they are exactly equal.
I've also added EMA smoothing option.
Enjoy!
