The convention in EL is to use [ ] , Close[1], to enclose time shifted data. I am not familiar with the formula you are using but I think there are no time shifts in there.... Sid

EasyLanguage. Twitcher concept was published in last month's FUTURES
Magazine. Code is from a user's group.
QUESTION: Does the following code for y refer to the next bar and next 2
bars or previous bars?
Y = u_2* price+2*u1*y1-u1_2*y2;
y2 = y1;
y1 = y;
Here's the entire EasyLanguage code (for the twitcher function)
EASYLANGUAGE FUNCTION:
Inputs: price(NumericSeries), initLength(NumericSimple);
variables: length(0), x(0), y(0), y1(0), y2(0), u(0), u1(0), u1_2(0),
u_2(0);
If initLength
<2 then length = 2 else length = initlength;
if CurrentBar = 1 then begin
x=(1- cosine(360/Length))/0.414213562;
u=-x + squareroot(x*x+2*x);
u1= 1.0-u;
u1_2=u1*u1;
u_2=u*u;
y1=price;
y2=y1;
end;
y=u_2* price+2*u1*y1-u1_2*y2;
y2=y1;
y1=y;
TWITCH=Y
