Here is another version by Mobius.

 

Code

# Zero Lag EMA (Using an Error Correcting Filter) # Mobius # Ported to TOS 08.31.2016 from Article by John Ehlers # Using an EMA error term, the current price – EMA[1], the amplitude of the error term is altered by multiplying the error by a gain term. The new filter is an EC or Error Corrected EMA. # Inputs: input Length = 20; input GainLimit = 50; input LabelsOn = yes; # Vars: def alpha; def BestGain; def EC1; def Gain; def EC; def Error; def LeastError; def EMA; alpha = 2 / (Length + 1); EMA = alpha * close + (1 - alpha) * EMA[1]; plot EMAdata = EMA; EMAdata.SetDefaultColor(Color.Yellow); Gain = fold g = -GainLimit to GainLimit do getValue(g / 10, g); EC1 = fold V = -GainLimit to GainLimit do alpha * (EMA + (fold i = -GainLimit to GainLimit do i / 10) * (Close - EC1[1])) + (1 - alpha) * EC1[1]; Error = AbsValue(Close - EC1); If Error < 1000000 Then { LeastError = Error; BestGain = Gain; } else { LeastError = LeastError[1]; BestGain = 0; } EC = alpha * (EMA + BestGain * (Close - EC1)) + (1 - alpha) * EC1; Plot ECdata = EC; ECdata.SetDefaultColor(Color.Cyan); AddLabel(LabelsOn, "Standard EMA", color.yellow); AddLabel(LabelsOn, "Error Corrected EMA", color.cyan); #End Code Error Corrected EMA
