Hello,
just past the code below (I made some changes to the plot statement)
*above* the first line in main price chart code, the one that
says //--Indicator-End--.
btop = BBandTop( C, Prefs( 4 ), Prefs(8)/100 );
bbot = BBandBot( C, Prefs(4), Prefs(8)/100 );
width = btop - bbot;
PctChange=100*(width-Ref(width,-1))/Ref(width,-1);
Plot(PctChange,"BwidthPctChg",colorBlack,styleNoDraw);

I am doing in order to learn all about the coding in the price
chart. It appears that you are supposed to somehow make the output
from all of those WriteIf(statements) appear in the commentary
window, which I have yet to feel the need to use.

built-in price chart. BTW, in this custom version, the Bollinger
bands ended up being super close together, even before I multiplied
by 100 for the last plot(statement).

involves those writeif() functions that I see in the code, which I
have also never used. later, Ron D
