Zero Lag Volume Price Confirmation Indicator

Implementation of Volume Price Confirmation Indicator with an added Zero Lag VPCI inspired by ZLEMA from Ehlers. It also supports a Fisher mode that can show interesting signals.


Based on docs.mta.org/docs/2007DowAward.pdf
Addendum (from the author):
"At the time, I believed a falling trend and falling VPCI was bearish, it is in fact a bullish indication."
"I also may have stated a falling trend and a rising VPCI was bullish, however it is a bearish indication."
