T3.new1,2 - T3

MetaStock 6.5 code for ILRS:

{input number of lookback periods, default is 11}

periods:=Input(“Periods? “,2,63,11);

{determine how many points are in the time series}

size:=LastValue(Cum(1));

{determine the constant of integration by taking the simple

moving average of the first periods points in the time

series}

start:=LastValue(Ref(Mov(P,periods,S),periods-size));

{value is the integral of linear regression slope plus the

constant of integration}

Cum(LinRegSlope(P,periods))+start;

If x stands for the action of running a time series through

an EMA, f is our formula for generalized DEMA with the

variable “a” standing for our volume factor:

f: = 1 + a x – ax2

FIGURE 1: HEWLETT-PACKARD. The EPMA(15), IE/2(15) and ILRS(15) are red,

blue and green, respectively in MetaStock. Note how the EPMA hugs the data more

closely than a simple or exponential moving average of the same length. The price

we pay for this is that it is much noisier than ILRS, and it also overshoots the data

when linear trends are present.

Running the filter though itself three times is equivalent to

cubing f:

–a3x6+ 3a2+3a3 x5+ –6a2–3a–3a3 x4+ 1+3a+a3+3a2 x3

Thus, the MetaStock 6.5 code for T3 is:

periods:=Input(“Periods? “,1,63,5);

a:=Input(“Hot? “,0,2,.7);

e1:=Mov(P,periods,E);

e2:=Mov(e1,periods,E);

e3:=Mov(e2,periods,E);

e4:=Mov(e3,periods,E);

e5:=Mov(e4,periods,E);

e6:=Mov(e5,periods,E);

c1:=-a*a*a;

c2:=3*a*a+3*a*a*a;

c3:=-6*a*a-3*a-3*a*a*a;

c4:=1+3*a+a*a*a+3*a*a;
