[amibroker] Re: Highest and Lowest Between two events and bar # when such hi/los' occur

["johsun" <joh.sun@xxxxxxxx>]

Rakesh,

I've seen your request for this before, and I intended to take a 
look at it but never got round to it.
 
But now I have some code for you...

The global variable bar holds the barindex. Keep in mind that if you 
call the function more than once 
you must assign this value to a new variable since subsequent 
function calls will overwrite it.

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 ---

m = MACD();
k = Cross( m, 0 );

x0 = HighestBetween( k, m, 0 );
bar0 = bar;

x1 = HighestBetween( k, m, 1 );
bar1 = bar;

Plot( m, "", colorRed, styleLine );
Plot( x0, "barindex " + bar0 , colorBlue, styleLine );
Plot( x1, "barindex " + bar1 , colorGreen, styleLine );



Regards,
Johan
