AmiBroker 5.00 onwards uses now new watch list system. Watch lists differ from other kinds of categories (as groups, markets, industries, sectors) in that, that you can assign single symbol to more than one watch list.
You can use UNLIMITED number of watch lists with their names definable in Symbol->Categories window. The members of each watch list is shown in the symbol tree under “Watch lists” leaf.
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).
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.
Adding / removing watch lists
You can now Add/Delete watch lists using Symbol->Watch List->New Watchlist and Symbol->Watch List->Delete Watch list menu or from watch list context menu. Note 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.
Adding tickers to watch lists
You can easily add a ticker to the watch list by simply clicking with a right mouse button over the item in the symbol tree and choosing Watch List->Add selected symbol option:
How to import/export watch list from/to file
1. Choose Symbol->Watch List->Import menu, or right click over watch list in the tree and choose Import.
