Elegant is in the eye of the beholder, Juan--sorry I meant Jose ;)

I believe Dimitris presented [commented] code that plotted in the background color till it was time to be seen.
<<Why - does x get worn out? :)>> Just good form, old boy :)
<<So, any thoughts on why this doesn't work:>>
The code I saw was
----
IIf(display=2, // <-----
Plot(0,"",colorBlue,styleLine),
Plot(Close,"",1,128));
IIf(display=2, // <----
Plot(signals,"EMA signals",colorRed,styleLine),
Plot(EMA1,"EMA",colorRed,styleLine));
----
We all copy Jose, [as with your <<x = IIf(x==1,O,IIf(x==1,H,IIf(x==1,L,IIf(x==1,V,C))));>>], the proof's in remebering to make the
changes you intended before inflicting it on the world.

Bob, Juan is not here - hope you don't mind if I reply instead... ;)

It's actually very simple code. Elegant if I may say so. There is no
redundant code there anywhere.
The purpose of this EMA:
Plot a normal EMA with 200 periods on a chart, and you'll see no plot
for the first 200 periods. My code takes care of that.

names.
Will do that from now on. Used to coding in MetaStock, where coding
space is minimal (2K).
> P = IIf(x==1,O,IIf(x==2,H,IIf(x==3,L,IIf(x==4,V,C)))); // don't
reuse x!!!
Why - does x get worn out? :)

The reason for this is that I intend to use this EMA on oscillators
with negative values as well, that is, as soon as I find the "P"
variable equivalent of MetaStock.
So, any thoughts on why this doesn't work:
IIf(display=2,
Plot(signals,"EMA signals",colorRed,styleLine),
Plot(EMA1,"EMA",colorRed,styleLine));
// If parameter display choisen = 2, plot EMA crossover signals,
otherwise plot EMA
Why is AB plotting both outputs?
