Dear Peter,
The code below (tested with QP2) should work just fine for you:
//////////////////////////
MaxGraph = 9;
EnableScript("jscript");
// this is to show only one entry per stock
ticker = name();
<%
CInfo = new ActiveXObject("QuotesPlus.CompanyInfo");
CInfo.Symbol = AFL("ticker");
// try-catch block handles the situation when
// QuotesPlus object returns strange values
try
{
AFL("Float") = Number( CInfo.Float() )*100000;
}
catch( e )
{
AFL("Float") = 0;
}
%>
cumvol = LastValue( cum( volume ) ) - cum( volume );
lastrange = cumvol < float;
dayone = ExRem( lastrange, 0 );
graph0 = close;
hh = LastValue( HighestSince( dayone, high ) );
ll = LastValue( LowestSince( dayone, low ) );
graph0 = close;
graph0style=64;
graph0color=2;
graph1 = IIF( lastrange, hh, -1e10 );
graph2 = IIF( lastrange, ll, -1e10 );
graph1style = graph2style = 1;
/////////////////////////////////////
