//Bollinger Bands with Expansion and Contraction
//HIGHLIGHTS
// Contraction Color: Blue
pds=20;//bollinger bands periods
shift=2;//bollinger band shift
ChartStyle=64;//Main chart style ex.64 = candlestick,
128=Barchart,1=line.
Cond1= BBandTop(Close,pds,shift)< Ref(BBandTop(Close,pds,shift),-1) AND
BBandBot(Close,pds,shift)>Ref(BBandBot(Close,pds,shift),-1);
// Expansion Color: Red
Cond2= BBandTop(Close,pds,shift)> Ref(BBandTop(Close,pds,shift),-1) AND
BBandBot(Close,pds,shift)<Ref(BBandBot(Close,pds,shift),-1);
barcolor=IIf(Cond1,6,IIf(Cond2,4,0));
Graph0=BBandTop(C,pds,shift);
Graph1=C;
Graph1Style=ChartStyle;
Graph2=BBandBot(C,pds,shift);
Graph0Style=Graph2Style=1;
Graph0BarColor=Graph2BarColor=ValueWhen(barcolor!=0,barcolor);
/**********************************************************/
Lookback=125;
diff=BBandTop(Close,pds,shift)- BBandBot(Close,pds,shift);
contraction_cond=IIf(diff < Ref(LLV(diff,Lookback),-1),1,0);
expansion_cond=IIf(diff > Ref(HHV(diff,Lookback),-1),1,0);
present=WriteIf(Cond1,"Contraction","Expansion");//is the market
currently under expansion or contraction
Filter=Cond1 > 0 OR Cond2 > 0 AND Close > 0 AND Close < 25 AND Volume >
5000;
AddColumn(IIf(Cond1,C,IIf(Cond2,C,C)),"close");
AddColumn(Cond1,"contract");AddColumn(ValueWhen(Cond1,BBandTop(Close,pds,shift)-BBandBot(Close,pds,shift),1),"ContractValue");
