Hi Warren

The formulas should run as indicators, with the noted effect that the last bar
won't plot.Explorations won't run with forward references.
I'd have to question whether the code is a typo. Usually someone that uses
one forward reference tends to use others as well. I'm not familiar enough
with the formulas to make a judgement on whether it's a typo or not. I
would go looking for another source for the code.
It's not difficult to reallign the code by increasing all bacward reference by
the required amount (from -1 to -2 for example), reducing all forward
references by 1 (from +1 to 0) and add a backward reference if none
already (from C to Ref(C,-1). This seems like a lot of work for code that
might just have a typo.
Hopefully there's someone out there that can put you right.
