This is the upgraded Jurik Price Trender Averages by Mladen and Mrtools which comes with Multi-timeframe mode (updated version with drop down box) + Interpolation, Color Change on Slope, Alerts & more.

Mrtools also kindly added Arrows on Crossover as well.

As explained by Mladen:
It can use those averages for smoothing the price prior to applying jurik smooth as signal to it.
