Final:
I have come to an explination:
Reserved Arrays clober
User arrays
on any subsequent calls to the same function.
Here is some code to show as an example:
Filter
=1;
function Any(array, period)
{
local LowValue;
//LowValue = LLV(array, period);
//ret = (100 * (array - LowValue) / (HHV(array, period) -LowValue));
}
Diff = Signal(12, 26, 9);
StochDiff = Any(Diff, 5); // 1st call
MyClose = Close;
JunkIgnored = Any(MyClose, 14); // 2nd call
JunkIgnored2 = Any(O, 14); // Reserved Array clobers User array
// On any subsequent calls.
AddColumn(C,"Close");
AddColumn(Diff,"Diff",1.4);
AddColumn(MyClose,"MyClose"); // Ends up being Open. (Clobered!)
AddColumn(O,"Open");
