IndicatorTrendOverlay
Overview
T3 Pass applies Tim Tillson's T3 moving average to any upstream numeric series. T3 chains six GD (Generalized Double Exponential) filters, controlled by a volume factor, to produce a smooth line with far less lag than a triple EMA.
Formula
GD(x,p,v) = (1+v)·EMA(x,p) − v·EMA(EMA(x,p),p) T3 = GD(GD(GD(x,period,v),period,v),period,v) (v ≈ 0.7)
