Fred,
T = 10; // Time Period
M = (H+L)/2;// your array here
EMA1 = EMA(M,T);
EMA2 = EMA(EMA1,T);
Diff = EMA1 - EMA2;
ZeroLagEMA = EMA1 + Diff;
Graph0 = ZeroLagEMA;
Following above defined ZeroLagEMA we have
ZeroLagEMA = EMA1 + Diff=EMA1+(EMA1-EMA2)=2*EMA1-EMA2=2*EMA(M,T)-EMA
(EMA(M,T),T)
The last part is DEMA(M,T) [see also
