When I attempt a direct backward reference (variable[n]) or indirect backward
reference (a crosses above b) in a simple function I get syntax errors. An Xavg
requires reference to the previous period value, so if you've got an example
where backward reference is performed withing the function, I'd like to see how
it's done. As I think about it, the example you saw probably recurses the same
variable so that the value being passed to the next iteration of the function is
the same as the value returned by the previous iteration e.g. xAvg =
f_xavg(xAvg)?
