This downloader gets NSE (National Stock Exchange) equities historical data. The data is downloaded for each date (and not per symbol). You just need to select the start and end dates and the downloader will create and download the appropriate dates quotes data and feed your quotes database.
The data is retrieved from the National Stock Exchange website (nseindia.com), and symbols are automatically added. This way, your database will always contain all the ticker symbols of companies listed in the NSE.
The volume field contains the number of shares traded while the open interest field contains the total volume traded.
Here is how the item works internally:
Given the start and end dates you provide, it creates a list of URLs with the URL-Script module, and then downloads each URL file (ZIP file). Each file is decompressed and then parsed and finally the quotes data are added in your database. This is just for information; all the process is done automatically. It takes you only few minutes to complete the downloading process.
