Re: [amibroker] AFL Guidance

["Steve Dugas" <sjdugas@xxxxxxxxxxx>]

Hi,

Here is one approach, assuming you have already ID'd the 2 events:

HighsBetweenEvents = IIf( Datenum() >= Event1 AND Datenum() <= Event2, High, 
0 );
HighestHigh = Highest( HighsBetweenEvents );
HighestHighDate= ValueWhen( HighsBetweenEvents == HighestHigh , Datenum() );

or using Zig function to find peaks:

MyZig = Zig( High, 5 );
ZigBetweenEvents = IIf( Datenum() >= Event1 AND Datenum() <= Event2, MyZig, 
0 );
HighestPeak = Highest( ZigBetweenEvents );
HighestPeakDate= ValueWhen( ZigBetweenEvents == HighestPeak , Datenum() );

Steve
