Graham...You are totally correct, that piece of code works correctly
if I was smart enough to write it as you had suggested it.
So now what i thought was working correctly isn't.
I was trying to go back on my chart and draw trendlines for the
preceeding 30days lets say, Which meant i would need the ability to
have many study id's and that way go back and run an explore on
those multiple hand drawn studys/trendlines.
The only way i can get it to work now is if i call
the "trendcheckup" procedure inside the for loop(see below). (that
gives me the arrows on the chart for the crosses for multiple lines)
BUT it doesn't allow me to run an explore on those points shown on
the chart.
If that makes any sense?
Plot(CCI(14),"",colorBlack,styleLine|styleNoLabel);
procedure trendCheckup(StudyID)
{
global ass;
Linup = Study(StudyID,1148);
TLBUP = Cross(CCI(14),Linup);
PlotShapes( TLBUP*shapeUpArrow,colorBrightGreen,0,L,-20);
ass=TLBUP;
}
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);
}
//trendCheckup("U"+alphai);
trendCheckup("XY");
Title = Name()+" "+ ass ;
Buy = IIf(ass>0,1,0);
Filter=Buy;
AddColumn(CCI(14),"CCI",3.2);
AddColumn(ass,"Buy",1);
