David,
You will not be able to use this in a system
tester, only to generate live signals, so I suggest you test this
thoroughly.
Substitute this line:
Num:= 0 - BC; {assuming BarsSince returns
non-negative number}
with
Num:= Lastvalue(Abs(BC));

Appreciate any suggestions. By the way, the error generated is "The
