Right. You are trying to pass in a variable that is declared inside the
function, thus the !!not defined error.
The variable you pass to your function needs to be the study ID or Chart
ID (I don't know exactly on this point as I haven't used these before).
Since your function asks for a variable you must supply one, hence the
!!syntax error

I appreciate you answer and time. the reason i am using a function
was for the multi trend line letters. I have tried to call the
function like you suggested but get an error saying the TLBUP is
used without being defined or if i use your code i get a syntax
error... expecting "(" after trendCheckup; I think i have been
chasing my tail so long i can't figure anything out
function trendCheckup(StudyID)
{
Linup = Study(StudyID,GetChartID());
TLBUP = Cross(CCI(14),Linup);
PlotShapes( IIf
((TLBUP),shapeUpArrow,shapeNone),colorDarkGreen,0,Graph0,Offset=20);
return TLBUP;
}
function trendCheckdown(StudyID)
{
LineDn = Study(StudyID,GetChartID());
TLBDN = Cross(LineDn,CCI(14));
PlotShapes( IIf
((TLBDN ),shapeDownArrow,shapeNone),colorDarkRed,0,Graph0,Offset=20);
return TLBDN;
}
alphai = "";
for( i = 0; i<27; i++ )
{
if (i==1) {alphai="A";}if (i==2) {alphai="B";}if (i==3) {alphai="C";}
if (i==4) {alphai="D";}if (i==5) {alphai="E";}if (i==6) {alphai="F";}
if (i==7) {alphai="G";}if (i==8) {alphai="H";}if (i==9) {alphai="I";}
if (i==10) {alphai="J";}if (i==11) {alphai="K";}if (i==12)
{alphai="L";}
if (i==13) {alphai="M";}if (i==14) {alphai="N";}if (i==15)
{alphai="O";}if (i==16) {alphai="P";}if (i==17) {alphai="Q";}if
(i==18) {alphai="R";}
if (i==19) {alphai="S";}if (i==20) {alphai="T";}if (i==21)
{alphai="U";}if (i==22) {alphai="V";}if (i==23) {alphai="W";}if
(i==24) {alphai="X";}
if (i==25) {alphai="Y";}if (i==26) {alphai="Z";}
trendCheckup("U"+alphai);
trendCheckdown("D"+alphai);
}
ass = trendCheckup(TLBUP); !!not defined
or
ass = trendCheckup; !!syntax
Buy = IIf(ass>0,1,0);
filter = buy;
