Re: Improving peformance of float analysis with AmiBroker 3.75 beta

["DIMITRIS TSOKAKIS" <TSOKAKIS@xxxx>]

Hi Peter,
The formula

cumvol = LastValue( Cum( Volume ) ) - Cum( Volume );
lastrange = cumvol < 1000000;
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;

works perfectly. Hence the program can not read "Float".
I do not know the reason.
