I got in on this late but will try to take a stab it
this.
I ran your code and am not sure if the logic is
correct.
When I plot the line:
<FONT face="Courier New"
color=#0000ff>itl:=Cum(sigtl+rsttl>-1)=1;
It only works once at the very
beginning of the chart. Since either <FONT
color=#0000ff>sigtl or rsttl
can only be 0 or 1, the addition of both sigtl and rsttl will be
greater than -1 very quickly and stay that way. <FONT
color=#0000ff>Cum will only find the first instance where sigtl
and rsttl are greater than -1. Besides, you have a Boolean operation
(rsttl>-1) mixed within a math
operation (sigtl+rsttl<FONT
color=#000000>), both within Cum.
While they may be allowed, they can get confusing quickly.
I usually see lines like that written
as:
<FONT
color=#0000ff>itl:=Cum(sigtl+rsttl)=1; {does the same thing with
less code}
If you want to check for each
instance where sigtl and rsttl are greater than -1, use <FONT
color=#0000ff>Sum or <FONT
color=#0000ff>ValueWhen.
I also see where you calculate <FONT
color=#0000ff>rmbts and do nothing
with it. Is it for a short exit?
I would suggest that you plot each variable
separately. See what they do and when. Work your way down through your
formula.
Being able to use <FONT
color=#0000ff>LastValue(X +PREV-PREV)<FONT
color=#000000> to trick functions to accept dynamic inputs in MS helps to create
formulas that can tune themselves, but a MAJOR re-write of MS formula
language is about 5 years past due.

Thanks Roy.Unfortunatly it does not work.Here's the
full code. Thanks again,JuanLookBack := 34;Resistance
:=ValueWhen(1,Cross(Mov(C, LookBack,S),C),HHV(H, LookBack));Support
:=ValueWhen(1,Cross(C,Mov(C, LookBack,S)),LLV(L,
LookBack));R1:=Resistance;S1:=Support;sigtl:=If(L>R1,1,0);sigts:=If(H<S1,1,0);rsttl:=If(H<R1,1,0);rstts:=If(L>S1,1,0);itl:=Cum(sigtl+rsttl>-1)=1;its:=Cum(sigts+rstts>-1)=1;rmbtl:=BarsSince(sigtl
OR itl)<BarsSince(rsttl OR itl);rmbts:=BarsSince(sigts OR
its)<BarsSince(rstts OR
its);stlong:=If(HHV(H,LastValue(PREV+BarsSince(rmbtl=0)-PREV))-ATR(6)*2.5<C,1,0);stlong;-----
