CHANGE LOG

CHANGES FOR VERSION 4.91.1 (as compared to 4.91.0)

• fixed symbol tree refresh after Watchlist->Import

CHANGES FOR VERSION 4.91.0 (as compared to 4.90.5)

• AA: new options in the context menu "Replace watch list with the results/selected results"
  This new option empties the watch list before adding results. The order of symbols in the result list is preserved in the watch list.
  
  
• Watchlists: context (right click) menu - now there is no WL selection dialog displayed
  If you select the watch list from symbol tree and click with RIGHT mouse button to bring up watch list menu the selected watch list is used automatically and watchlist selector dialog is not displayed.
  
  
• Watchlists: redesign - now there is no limit on number of watch lists you can use
  a) watch lists are now stored as text files inside "Watchlists" folder inside database. The folder contains of any number of .TLS files with watch lists themselves and index.txt that defines the order of watch lists. You can add your own .tls file (one symbol per line) and AmiBroker will update index.txt automatically (adding any new watch lists at the end)The .TLS files can also be open in AmiQuote.

  
  b) watch lists remember the order in which symbols were added, so for example if you sort AA result list in some order and then you"add symbols to watch list" the order will be kept in the watch list.

  
  c) you can now Add/Delete watch lists using Symbol->Watch List-> menu or from watch list context menuNote that if you have done any customization to the menu, you may need to go to Tools->Customize, select "Menu Bar" and press "Reset" button for this new menu items to appear.

  
  d) you can now alphabetically sort the symbols in the watch list

  
  e) all watch lists are shown in the symbol tree now, even if they are empty.

  
  f) for backward compatibility OLE automation WatchListBits/WatchListBits2 properties of Stock object continue to work for first 64 watch lists (bit states are transparently emulated)

  
  g) Watch lists created in 4.91 are not visible for older versions
  
  

• When changing selected symbol, the tree is not traversed to the bottom (root). Instead only current branch is checked and if symbol is selected only if it is present under this branch (This prevents unnecessary unfolding of "All" and other branches)

• AFL Editor: AUTOWORDSELECTION turned off
  

• AFL: switch/case statement added (completed: 2007-03-31) (ext.ID: 580). More information: http://www.amibroker.com/guide/v50/keyword/switch.html
  
  Example:
  
  for( n = 0; n < 10; n++ )
{
printf("Current n = %f\n", n );

switch(n) {
    case 0:
      printf("The number is zero.\n");
      break;
    case 3:
    case 5:
    case 7:
      printf("n is a prime number\n");
      break;
    case 2: printf("n is a prime number\n");
    case 4:
    case 6:
    case 8:
      printf("n is an even number\n");
      break;
    case 1:
    case 9:
      printf("n is a perfect square\n");
      break;
    default:
      printf("Only single-digit numbers are allowed\n");
    break;
   }

  

• AFL: break/continue statements added (supported inside for/while/do-while/switch statements). More information:
  http://www.amibroker.com/guide/v50/keyword/break.html
  http://www.amibroker.com/guide/v50/keyword/continue.html
  
  Example:
  
  for(i = 1; i < 1000; i *= 2 )
{
   if( i > 50 ) break;
   printf("%f\n", i );
}
  

• AFL: new C-like assignment operators +=, -=, *=, /=, %=, &=, |=

  New operators are shortcuts for some common operations.

  x += y; is equivalent to x = x + y;
  x -= y; is equivalent to x = x - y;
  x *= y; is equivalent to x = x * y;
  x /= y; is equivalent to x = x / y;
  x %= y; is equivalent to x = x % y;
  x &= y; is equivalent to x = x & y; // bitwise and
  x |= y; is equivalent to x = x | y; // bitwise or
  

   

• Enanced display in Real Time Quote window (dual-step change coloring - when field changes it is highlighted with bright yellow for 0.25 second then color changes to pale yellow and after a while to default (white) background))
