Thanks for trying, but I don't think this is it.  In the RMI(A, B),
the A appears to be a period variable equivalent to the
period of the RSI.  The B is a momentum variable.  It's
something like RSI(C - Ref(C, -B), A).  However, there is
some smoothing going on as well, and I can't tell how that
is done, unless it's the Wilder's smoothing described
farther down in the original reply.

That competing program from Miami allows us to do this:
RSI(C - C[N], K), where K is the period of the RSI and [N]
is equivalent to the Ref time variable.  It produces an
indicator that follows pretty much the same patterns as the
Metastock formulation of the RMI, but is extremely jagged
by comparison.  I don't know whether or not it incorporates
Wilder's smoothing.

Will try rewriting the function from the ground up, including
Wilder's smoothing and see whether it makes a difference.

Thanks again.
