You don't need to use looping.  Just use the bar-to-bar memory of 
variables inherent in EL.

The following code plots a ShowMe dot at the High of each bar after 
Close exceeds the top BBand, and turns it off when the close goes 
below the average (center of the BBand), and vice-versa for the 
bottom BBand.

(I didn't attempt to make it efficient, e.g. I called average() 
twice.  If you really wanted to make it efficient, you'd call 
average() once, StdDev() once, and calculate the BBands yourself with 
avg+2*SD, avg-2*SD.)

Inputs:  BBlen(20);

Vars:  UpBB(0), DnBB(0), HitUp(False), HitDn(False);

UpBB = BollingerBand(Close, BBlen, +2);
DnBB = BollingerBand(Close, BBlen, -2);

if (Close > UpBB) then HitUp = True;
if (Close < average(Close, BBlen)) then HitUp = False;
if (Close < DnBB) then HitDn = True;  
if (Close > average(Close, BBlen)) then HitDn = False;

if HitUp then plot1(High, "Up");
if HitDn then plot2(Low, "Dn");
