EMA is a function of todays Close and yesterdays
EMA.
The mechanism is analytically described in AFL>AFL
Scripting Host>Examples>a) Indicator example - Exponential moving

After the math transormation, we may solve for C and get the
Reverse EMA function.
I will call it CLOSEviaEMA to be more expressive.
In Indicator builder paste the
