hi brian.
place this in the indi builder.
the blue lines are the bbband top and bottom,
the blue changing to red is when the difference between the top and
bottom bands contract when the difference is at the llv of 10 days.
the red changing to light blue is when the value of todays
difference + yesterdays difference is less than then
yesterdays difference + the difference 2 days ago. (when its at the
llv 10.
place this in the indi builder to see if the light blue lines is
the area you are looking for.
bbtop = BBandTop(Close, 35, 2);
bbbot = BBandBot(Close, 35, 2);
Aa=bbtop-bbbot;
bb=IIf(aa<Ref(LLV(Aa,10),-1),1,0);
Cc=ValueWhen(bb==1,C,1);
bb2=IIf(aa<Ref(LLV(Aa,10),-1),4,6);
dd=IIf(BarsSince(bb2==6)==1,1,0);
ee=IIf(bb+Ref(bb,-1)<Ref(bb,-1)+Ref(bb,-2),4,0);
Plot(bbbot,"",bb2+dd+ee,4);
Plot(bbtop,"",bb2+dd+ee,4);
Plot(C,"",1,64);
cheers: john.
