Hi all, I got a reference code for drawing trend lines.

Can somebody help draw line ('LineArray' function) by joining the recent 2 points of HHs (as well as HHs, LLs, HLs, LHs by individual lines).

Also requirement is to join 2 points alone and not to extend more than recent 2 points. The line needs to get extended left and right until today. And also the extended line's value (ie., today's value of the extended line) is expected to display.

Here is the code:
HTML: 
Q = Param( "% Change", 2, 0.1, 10, 0.1 );
Z = Zig( C , q ) ;
HH = ( ( Z < Ref( Z, -1 ) AND Ref( Z, -1 ) > Ref( Z, -2 ) ) AND (Peak( z, q, 1 ) > Peak( Z, q, 2 ) ) );
LH = ( ( Z < Ref( Z, -1 ) AND Ref( Z, -1 ) > Ref( Z, -2 ) ) AND (Peak( Z, q, 1 ) < Peak( Z, q, 2 ) ) );
HL = ( ( Z > Ref( Z, -1 ) AND Ref( Z, -1 ) < Ref( Z, -2 ) ) AND (Trough( Z, q, 1 ) > Trough( Z, q, 2 ) ) );
LL = ( ( Z > Ref( Z, -1 ) AND Ref( Z, -1 ) < Ref( Z, -2 ) ) AND (Trough( Z, q, 1 ) < Trough( Z, q, 2 ) ) );
GraphXSpace = 5;
dist = 0.5 * ATR( 20 );
 
for ( i = 0; i < BarCount; i++ )
{
    if ( HH[i] )
        PlotText( "HH", i, H[ i ] + dist[i], colorYellow );
 
    if ( LH[i] )
        PlotText( "LH", i, H[ i ] + dist[i], colorYellow );
 
    if ( HL[i] )
        PlotText( "HL", i, L[ i ] - dist[i], colorPink );
 
    if ( LL[i] )
        PlotText( "LL", i, L[ i ] - dist[i], colorPink );
 
}
