I haven't actually tried this with something like RSI, which has
lots of exponential moving averages in its calculation, at least
in the traditional implimentation, but what you want, conceptually
is simply to solve for another variable in an equation.
Suppose your equation were:
X = A + B * Y
and you want instead to solve for Y. Then you'd have:
Y = (X - A) / B
You might see if this idea could be used to solve your problem.
