This package provides a Python interface to download National Stock Exchange (NSE) bhavcopy data for Equities, Indices and Derivatives. The package provides functions to download daily bhavcopy data in CSV format, store the data in local storage, and update the data for any missing dates.
Update: On 5th March 2021, I had to make major changes to the article, as NSE stopped supporting full_bhavcopy_save for all years before 2020, if you are interested in reading the previous article, just see the Github change history.

To be honest, it is straightforward and tempting to create your own program using the requests library of Python, which can do this task for you every day after 16:00 IST to collect this data. But why reinvent the wheel when there are already several options out there?
There are two functions in the jugaad-data library, one is full_bhavcopy_save and the other is bhavcopy_save, we are using the latter one as it even when it has less information because NSE is slowly removing the full_bhavcopy data from its website if you try to run full_bhavcopy_save for any dates before 2020, it throws up an error.
**Whitespaces **i.e., all leading and trailing spaces are very common, and you will come across them from time to time; the best is to get rid of them at the start, so you don't see any issues later on. The below image shows the unique entries in the SERIES column from another full_bhavcopy_file which has leading whitespace; However, the file we are dealing with does not have this, let's still get rid of any whitespace in the columns and the data in those columns just in case they appear in the future and break our code.
Create a class that contains the Column name as available in Nse Bhav Copy financial Data. The Purpose of creating a separate class is to avoid defining the header name multiple times and this will have global scope , so we can use this attribute of this class using the dot (.) operator
For any trading month, the total rollover is usually expressed as a percent which is calculated using the open interest data for all the future series. The rollover percent for the Nifty 50 futures is calculated as:
This blog details a scenario where 4 Google Cloud services are put together for a solution, detailing the integration between these. Now before you start, this whole exercise can be done with a single loop in python or any programming language, but that is not the point. As a learning exercise, you will know:
By using transaction in line 4, the code ensures that only one process gets to create the metadata entry in database. Return value from this function tells the main program whether the process is duplicate or not.
The End of Day data files are generated in binary format at the end of each trading day. These files contain the End of Day bhavcopy information along with security and trade details pertaining to the Capital Market, Wholesale Debt Market and Futures and Options Segments of National Stock Exchange of India Limited. The tariff applicable for subscription of End of Day data is as under:
