The answer you probably need was kindly provided to me a group member
JohSun(I hope I have his ID right).

The code is pasted below
===================

function LOWESTBetween( _expression, array, n )
//Returns the highest ARRAY value between the Nth most recent
//occurrence of True _EXPRESSION and the one prior to that.
{
  global bar;
  bx = BarIndex();
  e = _expression;
  a = array;

  Ls  = LowestSince( e, a );
  Lsb = LowestSinceBars( e, a );

  Lb  = IIf( n, ValueWhen( e, Ref( Ls, - 1 ), n ), Ls );
  bar = IIf( n, ValueWhen( e, bx - Ref( Lsb, - 1 ), n ) - 1,
        bx - Lsb );

  bar = LastValue( bar );

  return LastValue( Lb );
}

===================

function HIGHESTBetween( _expression, array, n )
//Returns the highest ARRAY value between the Nth most recent
//occurrence of True _EXPRESSION and the one prior to that.
{
  global bar;
  bx = BarIndex();
  e = _expression;
  a = array;

  Hs  =HighestSince( e, a );
  Hsb = HighestSinceBars( e, a );

  Hb  = IIf( n, ValueWhen( e, Ref( Hs, - 1 ), n ), Hs );
  bar = IIf( n, ValueWhen( e, bx - Ref( Hsb, - 1 ), n ) - 1,
        bx - Hsb );

  bar = LastValue( bar );

  return LastValue( Hb );
}

===================

Example of use:

Dk_D = Cross(0,MACD() );
DK_U = Cross( MACD(),0 );
Occ=Param("occ",0,0,10);


LP1 = LowestBetween( Dk_D, L, 0 );
LPB1 = bar+1;
===================


Hope that helps.
