Is there a way to avoid the use of PREV Function in these formulas??It's too "heavy" for use on Intraday charts:-(

Here you go. It's not worth much, but knock yourself out. You should
read Roy's newsletter and learn to program for yourself. It's worth
every penny.

AMA-1

Periods:=12;
Direction := CLOSE - Ref(CLOSE,-periods);
Volatility := Sum(Abs(ROC(CLOSE,1,$)),periods);
ER := Abs(Direction/Volatility);
FastSC := 2/(2 + 1);
SlowSC := 2/(30 + 1);
SSC := ER * (FastSC - SlowSC) + SlowSC;
Constant := Pwr(SSC,2);
AMA:=If(Cum(1)=periods +1,Ref(C,-1)+constant*(C-Ref(C,-1)),
PREV*(1-Constant)+C*Constant);
AMA;

AMA-2

Periods:=26;
Direction := CLOSE - Ref(CLOSE,-periods);
Volatility := Sum(Abs(ROC(CLOSE,1,$)),periods);
ER := Abs(Direction/Volatility);
FastSC := 2/(2 + 1);
SlowSC := 2/(30 + 1);
SSC := ER * (FastSC - SlowSC) + SlowSC;
Constant := Pwr(SSC,2);
AMA:=If(Cum(1)=periods +1,Ref(C,-1)+constant*(C-Ref(C,-1)),
PREV*(1-Constant)+C*Constant);
AMA;

MACD AMA

signal:=Input("Enter the signal periods:  ",3,50,9);
Fml("AMA-1")-Fml("AMA-2");
Mov(Fml("AMA-1")-Fml("AMA-2"),signal,E)


The DEMA smoothed MACD is much better.

shortperiods:=Input("Enter the shorter DEMA periods:  ",3,20,12);
longperiods:=Input("Enter the longer DEMA periods:  ",21,50,26);
signal:=Input("Enter the number of signal line periods:  ",3,50,9);
Dema(C,shortperiods)-Dema(C,longperiods);
Mov(Dema(C,shortperiods)-Dema(C,longperiods),signal,E)
