I was looking for this indicator on our site and found out Mrtools made a newer, updated version of the ALB (Adaptive Lookback) Triangular Moving Average Prize Zone which he kindly added Center Line to in our Coding Help section.
I'll post it in this thread just in case some one is looking for it.

This indicator comes with Multi-timeframe + Interpolation, Smoothing Options, Alerts & more.

Thanks Mrtools.
