Ok, this is what I have so far:
======================

======================
---8<-----------------
{ Volume adaptable EMA v1.0 }
{ EMA samples bars with above-avg Volume }

pds:=Input("EMA periods",1,2520,21);
x:=Input("use Open=1 High=2 Low=3 Close=4 WClose=5 P=6",1,6,4);
shift:=Input("EMA vertical shift %",
-100,100,0)/100+1;
plot:=Input("[1]EMA, [2]Data, [3]Sampling bars, [4]Crossovers",1,4,
1);
{ Select price field }
x:=If(x=1,O,If(x=2,H,If(x=3,L,If(x=5,WC(),If(x=6,P,C)))));
{ Above average Volume points }
VolAvgPlus:=V>Mov(V,pds,E);
{ Select above-avg bars for EMA }
x:=ValueWhen(1,VolAvgPlus,x);
{ Reduce periodicity on low bar count }
pds:=If(pds>Cum(IsDefined(x)),
Cum(IsDefined(x)),pds);
{ EMA }
Ema:=x*2/(pds+1)+PREV*(1-2/(pds+1));
Ema:=Ema*shift;
{ Crossover signals }
signals:=Cross(x,Ema)-Cross(Ema,x);
{ Plot on price chart }
If(plot=1,Ema,If(plot=2,x,
If(plot=3,VolAvgPlus,signals)))
