Re: [amibroker] Re: Easy way of finding MAX or a large list

[Tomasz Janeczko <groups@xxxxxxxxxxxxx>]

Hello,

That is of course **NOT** true when it comes to array variables.
Array-aware MAX

x = MAX( array1, array2 );

is orders of magnitude faster than equivalent

for( i = 0; i < BarCount; i++ )
  if( array1[ i ] > array2[ i ] ) x[ i ] = array1[ i ];
  else x[ i ] = array2[ i ];

The original poster question was far too general. He did not mention
if he uses arrays or not and how he defines "the list" of values.

Best regards,
