Float Analysis Revisited

["Peter Gialames" <investor@xxxx>]

If I wanted to modify the float analysis code (below) to start counting
backward from any date entered how would I do that?

My problem is that I do not completely understand the line
lastvalue(cum(volume))-cum(volume). The way I read it is to sum all the
volume on a given chart and subtract this from the last value of the
cum(volume) array. Now once the cumvol < float this is our starting point.
But what if I wanted to start the counting backwards yesterday - or five
days ago?

I am going to do this in VB also to practice the new powerful features of
AmiBroker, but an explination of how to do this in AFL would be appreciated.

EnableScript("jscript");

// this is to show only one entry per stock

ticker = Name();

<%
CInfo = AFL.CreateStaticObject("QuotesPlus.CompanyInfo");
CInfo.Symbol = AFL("ticker");

// try-catch block handles the situation when
// QuotesPlus object returns strange values

try
{
AFL("Float") = Number( CInfo.Float() )*1000000;
}
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;
