thanks, tj, your are right.
some times the tree doesn't permit to apreciate the forest :-))
so i work hard to by pass such situations, i've tried a lot
solutions, but finaly this can be the more easier
P = ParamField( "Price field" );
periods = Param("Periods", 15, 1, 200, 1 );
suma=Param ("suma",10,10,1000,10);
a=Ref (p,-periods)+suma; //here add enaugh to convert positive all
range of indicator.
b=p+suma;
r=(b-a)/a;
Plot( r, _DEFAULT_NAME(), ParamColor( "Color", colorCycle ),
ParamStyle("Style") );
another solution i try was
iff (a[1] =0, r=0,r=(b-a)/r
(or >00,1 and < -0,1, or oposite, or...)
don't be literal code couse I try more than 50 diferente solutions,
if-then, while,iif but if seems a[] on a ifthenelse condition
doesn't function at all and I delete it until I think on upper code.
can you tell my how use a array value on a IF condition like
if (a[1]<0,1 and a[1]<-0.1).......
tia.
