I have 10,000 plus securities in my AmiBroker DB so the Quote editor it not efficient way to handle.
I think my question correctly states that I imported an ASCII DB to AmiBroker not that I am working with an ASCII DB is AmiBroker. The data is imported and Watchlists created from the imported DB.
If I can’t delete the data and re-import a new DB with all the same symbols as those in the created WathLists the efficient solution will be to copy all the symbols in each Watchlist as file, then delete/remove the symbols, import and create a new DB, and then recreate the WatchLists.
Since the imported DB is static, an option to overwrite all data on the import would be helpful. As if now, it seems you can import data and it will overwrite the data if a date if the date exists in the new & old file, but if the date exists in the old file and not in the new file, the old date and data is kept and not deleted.
Thanks for your reply.
