Default Data Handling



HI all,
probably all of us who read this thread are using ABroker for charting.
I am starting this thread to share our knowledge and resources for data handling and data manipulation for amibroker.
I have an afl which can export ami data to csv file either in single file or in diff files for diff stocks for a single day or a time range.(probably many of us alrdy got it).

Is there any afl which can delete quotation for a stocks/all stocks in the database for a particular day or a time range specified by user?
please let us know.

Manipulating a database might corrupt the entire data.

Wouldn't it be wiser to do the following: download quotes afresh twice -- [1] from the start of original range to start of new range
[2] from the end of new range to end of original range

I am not fully aware of all the functions that AFL exposes, sorry

see if u want to manipulate any database u should keep a backup atleast and this is the min requirement.
downloading the fresh database is not a easy task as time and money is concerned(data downloading is not free you know).
So I thiink deleting the required dated data using afl or other means is highly important.
