I stuck with a problem and would appreciate getting a direction -
Want to plot (EMA8 + average price distance from EMA8 last year).
The same goes for (EMA8 + maximum distance from the EMA last year)
The main problem I encountered was to find the average distance in the past year and the maximum distance.
Again, I apologize for the digging but it's pretty stuck here

You'd have to custom code this, I think. I don't recall anyone mentioning something that would do that for you 'out of the box'.

For the maximum distance, assuming you don't care whether price is above or below the EMA, you'd want to take the value of each and subtract them, then get the absolute value, Math.Abs(), store that in a variable and replace the value any time the current value is greater than what's already stored in the variable.

Something like this:
Diff = Math.Abs(EMA8 - Price)
if (Diff > Variable)
Variable = Diff

Then run that over the past year's historical price bars. The end value for Variable ought to be the maximum distance price was from the EMA over the year. Then you'll need to plot the value.

The average distance, again assuming you don't care which is higher, would be something like:
NewVariable = SMA(Diff)[365]
Meaning, plot some variable making it equal to a simple moving average of the absolute value of the difference between the EMA and price, making the period of the moving average = 1 year.

I'm not a master programmer and just sort of threw this together, so I might be making some dumb mistakes, but I think coding similar to this, conceptually, will get you what you want.
