Does this example of fraction of high, low range for close (can use other array and range) do what you want?

 

x = lastvalue(highest(h));

y = lastvalue(lowest(l));

fraction = c / (x - y);

plot(fraction, ... );

Almost...what I really want to plot/determine is the percentile itself (i.e. somewhere between 0 and 1) not what the percentile value is equal too.  For example if 999 was in the 99th percentile the plot would be  .99 not 999.

The cum function definitely captures the total array part.  If I could set the periods part of RSIa to Cum I'd be in there!

Tks

Var = RSI();
count = Cum(Var>0); //number of array elements
period = LastValue(count) ;
perc = Percentile(Var, period,50) ;
Plot(LastValue( perc), "", colorRed);
