This usually occurs because on some bar your system looks back that many bars. It does not have to be during the initial bars but can occur on any bar.
You might be saying something like:
BarCount = BarCount + 1;
if XXX then BarCount = 0;
.....
PastHigh = High[BarCount];
At some point the BarCount variable could get up to some big number. Look at every case where you refer back to a past value and make sure the look back is limited to same value, independent of the data.
