A little update. I replaced the simple moving average for the smoothed simple moving average, as I find it better for smoothing purposes.
Also, I decided to make the unsmoothed PVT RSI as the standard.
To make it smooth, just change the SMMA Length for an integer larger than 1.
I built this indicator for experimental purposes only.
There's no deliberate interpretation to it, besides maybe pattern recognition or as an indicative of sudden PVT change.
