Re: [amibroker] Determining Range of Dates displayed in Current Chart

[William Peters <william@xxxxxxxxxxx>]

Hi,

Below are two functions which will return the first and last visible
dates followed by an example using title.

function LastVisibleDate()
{
         Version(4.70);
        DateArray = DateNum();
        Lvbindex = Status( "lastvisiblebarindex" );
        Lbindex = BarCount - 1;

        if ( Lvbindex > Lbindex  )
                Lvb = DateArray[ Lbindex ];
        else
                Lvb = DateArray[ Status( "lastvisiblebar" ) ] - 1;

        DayNm = round( frac( Lvb / 100 ) * 100 );
        MthNm = round( frac( Lvb / 10000 ) * 100 );
        YrNm = int( Lvb / 10000 ) + 1900;
        
        return NumToStr( DayNm, 1.0 ) + "/" + NumToStr( MthNm, 1.0 ) + "/" + NumToStr( YrNm, 1.0, False );
}

function FirstVisibleDate()
{
         Version(4.70);
        DateArray = DateNum();
        Fvb = DateArray[ Status( "firstvisiblebar" ) ];

        DayNm = round( frac( Fvb / 100 ) * 100 );
        MthNm = round( frac( Fvb / 10000 ) * 100 );
        YrNm = int( Fvb / 10000 ) + 1900;
        
        return NumToStr( DayNm, 1.0 ) + "/" + NumToStr( MthNm, 1.0 ) + "/" + NumToStr( YrNm, 1.0, False );

}

/* Example of how to use these functions */
Title = " First visible bar: " + FirstVisibleDate() + " Last Visible Bar: " + LastVisibleDate();
