Getbhavcopy: Free NSE and BSE data downloader

A new version of Getbhavcopy has been released to fix the following issues:

• Till version 2.0.3 Getbhavcopy used to send a post to NSE to generate the CSV file for the index and then downloaded that csv file with index data. Recently I was noticing a lot of 404 Not Found errors being returned from NSE server randomly while downloading the NSE Indices data file.

Version 2.0.4 changes the approach in the way it downloads the Indices data. The indices data is downloaded from NSE itself but now does not depend on the CSV file, this way we will not notice the random 404 Not found errors

The following is the error I am talking about, notice the random 404 errors below. These are now fixed

• The other issue fixed is with the NSE Indices volume calculation. This issue does not effect those who download  data every day. However if you are used to download bulk data (i.e. for a range of dates) in one shot then you would face this issue. The issue is that the NSE indices volume is incorrectly calculated and the volume keeps on adding for each day. Hence you will have a volume pattern as follows.

Notice how the volume keeps on rising till one day and then it drops. Those are the range of dates for which I downloaded data (i.e. start dates and end dates while downloading).

All other data is perfect just the indices volume is erroneous if downloading for more than one day. This issue is also fixed now.
