hi guys,
I visited this site today itself and found it quite helpful for myself.
I also installed MetaStock tool and wanted to gather some historic data which ofcourse is not always uptodate.
So I quickly wrote a utility to download the set of 3 month old BhavCopies from NSE-India.com. (Thankfully MS quotes till 14-Jun are already available).
Here I'm posting the simple C# Code which will download all the bhavcopies into your C:\NSE folder.
I'm posting the code so you can tweak it according to your requirments.
Also attached is an executable file which upon doubleclicking will download the files to C:\NSE folder.
Note - You will have to create the NSE folder in C drive manually.
I'm also trying to write a CSV converter so that it will be easy to import from Downloader. If I get some time I'll post it in few hours.
For any queries you can contact me at talksandy AT airtelbroadband.in
