Might I suggest you look at changing Pring's 'Ema' variable from
Ema:=If(H1,If(PREV=0,CLOSE,(C1*Pct)+(PREV*(1-Pct))),PREV);
to
Ema:=If(Cum(H1>0)=1,C1,ValueWhen(1,H1,PREV)*(1-Pct)+(C1*Pct));
The seeding does not use PREV, and the use of ValueWhen() allows the removal
of a second PREV. The result is a one PREV variable rather than a three
PREV variable, and therefore the the indicator is less resource hungry.
Another adaptation that might be useful for some is a "dynamic last period",
where an incomplete frame uses the current close. One has to remember that
this value will change up until the last bar of data for the frame is added.
The feature is added by using a "last bar" piece of code to also trigger the
"end of frame" signal. Once again using Pring's code as a starting point,
H1:=Minute()=30 OR (Hour()*100+Minute())=1600;
becomes,
Lb:=LastValue(Cum(1)-0)=Cum(1);
H1:=Lb OR Minute()=30 OR (Hour()*100+Minute())=1600;
