Dimitris,
Excellent solution as always.
As I wrote earlier I can bypass this using DiskFileWatchLists
(http://finance.groups.yahoo.com/group/amibroker-
dll/files/FV/fvDiskFileWatchList/), however it is nice to have more
than one way of doing things. If one is talking about pretty long
lists then inputting them in the string such as what you've written
will be quite tedious, but for short lists your solution is an
*outstanding* one.
Maybe I should next version of the DLL that will take-up the list
from disk as initialization, will in memory and then Index it by
tickers.
Regards,
