Where are watch lists stored?
AB manual is user's best friend:
Watchlists are stored per data base (DB) and they are stored in each DB's sub-folder named WatchLists.
"WatchLists" folder contains files with file extension TLS (and file name being name of filled watchlist. And each file contains symbol list of that watchlist). In addition that sub-folder contains single file named index.txt (containing the order of watchlists).
