Functions do not execute until they are called. You are never calling
the function. If you want it inline as you are expecting, just remove
the function wrapper. Otherwise you must:
a) return something from the function,
b) call the function to get results.
___________________________________________
Try this with no function:
ass=0; //Not necessary
Linup = Study(StudyID,GetChartID());
TLBUP = Cross(CCI(14),Linup);
PlotShapes( IIf
((TLBUP),shapeUpArrow,shapeNone),colorDarkGreen,0,Graph0,Offset=20);
ass = TLBUP;
Buy= IIf(ass>0,1,0);
__________________________________________
Or this as function:
ass=0; //Not necessary
function trendCheckup(StudyID)
{
Linup = Study(StudyID,GetChartID());
TLBUP = Cross(CCI(14),Linup);
PlotShapes( IIf
((TLBUP),shapeUpArrow,shapeNone),colorDarkGreen,0,Graph0,Offset=20);
return TLBUP;
}
ass = trendCheckup; //Calls function, stores result in your variable
Buy= IIf(ass>0,1,0);
PS: Since the code inside the function is only executed once, a function
call is not necessary. I would just use the first example.

Thanks for your reply Graham, however im still lost... here is what
i have done>>> the first piece of code per your suggestions produces
no explore results. I do get a (1) in the title results at the
proper point in the title, so why wouldn't i get a buy=1 and
therefore a flag to show the results of an explore instead of zero
returned explore results. Im must be missing something very basic
but i don't see it? (see second piece of code below)
Plot(CCI(14),"",colorBlack,styleLine|styleNoLabel);
ass=0;
function trendCheckup(StudyID)
{
Linup = Study(StudyID,GetChartID());
TLBUP = Cross(CCI(14),Linup);
PlotShapes( IIf
((TLBUP),shapeUpArrow,shapeNone),colorDarkGreen,0,Graph0,Offset=20);
ass=TLBUP;
}
Buy= IIf(ass>0,1,0);
Filter=Buy;
trendCheckup("XY");
Title = Name()+" "+ ass ;
AddColumn(CCI(14),"CCI",3.2);
AddColumn(ass,"Buy",1);
>>>>>>HOWEVER This code Does produce expore results... isn't it the
same in essence???
Line = Study("ug",1142);
e=Cross(wcci,Line);
f=Cross(Line,wcci);
//PlotShapes(IIf
((e),shapeHollowUpArrow,shapeNone),colorGreen,0,Graph0,Offset=10);
//PlotShapes(IIf
((f),shapeHollowDownArrow,shapeNone),colorRed,0,Graph0,Offset=10);
Buy= IIf(e>0,1,0);
bby=Buy;
AddColumn(bby,"bby",1);
