## Zero Lag EMA

Here's my Metastock 6.2 coded version of the Zero Lag Moving Average, as described in the April, 2000, issue of Technical Analysis of Stocks and Commodities. I've also used it to construct a Zero Lag MACD and a Zero Lag MACD trigger signal.

Period:= Input("What Period",1,250,10);
EMA1:= Mov(CLOSE,Period,E);
EMA2:= Mov(EMA1,Period,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA:= EMA1 + Difference;
ZeroLagEMA

## Zero Lag MACD

EMA1:= Mov(CLOSE,13,E);
EMA2:= Mov(EMA1,13,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA13:= EMA1 + Difference;
EMA1:= Mov(CLOSE,21,E);
EMA2:= Mov(EMA1,21,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA21:= EMA1 + Difference;
ZeroLagMACD:=ZeroLagEMA13 - ZeroLagEMA21;
ZeroLagMACD

## Zero Lag MACD Trigger Signal

(To be used with the ZeroLag MACD above)

EMA1:= Mov(CLOSE,13,E);
EMA2:= Mov(EMA1,13,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA13:= EMA1 + Difference;
EMA1:= Mov(CLOSE,21,E);
EMA2:= Mov(EMA1,21,E);
Difference:= EMA1 - EMA2;
ZeroLagEMA21:= EMA1 + Difference;
ZeroLagMACD:=ZeroLagEMA13 - ZeroLagEMA21;
EMA1:= Mov(ZeroLagMACD,8,E);
EMA2:= Mov(EMA1,8,E);
Difference:= EMA1 - EMA2;
ZeroLagTRIG:= EMA1 + Difference;
ZeroLagTRIG

## Zig Zag Validity

perc:=Input("Percent",2,100,10);
Z:=Zig(C,perc,%);
last:=ValueWhen(1,
( Z > Ref(Z,-1) AND Ref(Z,-1) < Ref(Z,-2) )
OR
( Z < Ref(Z,-1) AND Ref(Z,-1) > Ref(Z,-2) ),
Ref(Z,-1));
pc:=(C-last) * 100 / last;
pc:= Abs(pc);
SD:=(z>Ref(z,-1) AND Ref(z,-1)>Ref(z,-2)) OR (z<Ref(z,-1) AND
Ref(z,-1)<Ref(z,-2));
res:=If(pc>=perc ,1,0);

## Zigzag Validity Indicator

Spyros Raftopoulos

1=valid last leg of zig,

-1=invalid last leg of zig.

DO NOT use this indicator in systems}

perc:=Input("Percent",0.2,100,10);

Z:=Zig(C,perc,%);

last:=ValueWhen(1,

( Z > Ref(Z,-1) AND Ref(Z,-1) < Ref(Z,-2) )

OR

( Z < Ref(Z,-1) AND Ref(Z,-1) > Ref(Z,-2) ),

Ref(Z,-1));

pc:=(C-last) * 100 / last;

pc:= Abs(pc);

SD:=(z>Ref(z,-1) AND Ref(z,-1)>Ref(z,-2)) OR (z<Ref(z,-1) AND

Ref(z,-1)<Ref(z,-2));

res:=If(pc>=perc ,1,0);

res:= If(Alert(res,2) AND SD,1,res);

## ZigZag - Hi/Lo

{ High/Low ZigZag v1.0 }{ Plot on price chart }{ ©Copyright 2004 Jose Silva }{ [email protected] }

pr:=Input("ZigZag reversal amount", 0.001,100000,5);
choose:=Input("Hi/Lo ZigZag,  Close ZZ,  Peaks/Troughs",1,3,1);

pk:=PeakBars(1,H,pr)=0;
tr:=TroughBars(1,L,pr)=0;
pktr:=pk-tr;

zz:=Zig(C,pr,%);
zzHi:=Zig(H,pr,%);
zzLo:=Zig(L,pr,%);
avg:=(zzHi+zzLo)/2;

x:=
If(pk,zzHi,If(tr,zzLo,If(avg>Ref(avg,-1),H,L)));
zzHiLo:=Zig(x,pr,%);

If(choose=1,zzHiLo,If(choose=2,zz,pktr))
