The reverse of the indicators can be useful when you are trading using
breakouts, via signals from indicators. If you are looking for a break with
the ema you can determine the price it needs to go to for that condition to
occur

Greg,
You miss the important ", if we suppose next bar EMA."
There is a relation between 3 parameters :today´s EMA, tomorrow´s EMA
and tomorrow´s CLOSE. We need two of them to know the 3rd.
If we know today´s EMA and we suppose tomorrow´s EMA, then we can
calculate tomorrow´s CLOSE.
