Dave, I just tried it out and the display did not
change when I had different tickers in the ticker window.
I think that Cum function is dependent on the number of
bars in the issue(ticker) displayed,
since it will go from the first bar and accumulate
going forward in time to the last bar.
Could it be you had tickers with
different number of bars? however when I tried it
didn't make any difference whether I had IWM or
XOM as the display. Could
not replicate what you're seeing.

Subject: [amibroker] CumAdvDel Scan
Numbers Change
Hi Everyone
This is driving me nuts. Why does the cumulative
number change for AdvDecl after I've run the scan, plotted it and change
tickers. For example, I've run this in AA, Scan( I believe I swiped it from TJ
somewhere). Its then plotted. But the numbers for AddDecLine change depending
on which ticker is shown on adjacent window. Why should AddDecl change with
different tickers if I don't rerun AA scan?
I most be dense. This has gotta be
simple!
Thanks
Dave
AddToComposite(ROC(C,1)>0,"~UpBars","X");

Filter= 1;
Difference = ( Foreign("~UpBars","X")
-Foreign("~DnBars","X")) / (Foreign("~NcBars","X") + 1);
DiffSqrt = IIf(Difference>0,sqrt(Difference), -sqrt(-Difference));
AddDecLine = Cum(DiffSqrt);
