["nirvana1x" <nirvanaiam@xxxx>]

hi brian is this what you want.


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);
dd=BarsSince(bb==0)==1;
Plot(bbbot,"",2,4);
Plot(C,"",1,64);
Plot(bbtop,"",2,4);
Plot(Cc,"",6,4);
Plot(dd,"",1,4);
Filter = Close > 0 AND Close < 25 AND Volume > 5000 AND dd==1;


AddColumn(C,"close");
AddColumn(Aa,"bbanddiff");
AddColumn(bb,"llvbbanddiff");
AddColumn(Cc,"cc");
AddColumn(dd,"dd");
AddColumn(V,"volume");
AddColumn(RSI(),"rsi");
AddColumn(ADX(),"adx");

cheers: john.
