How to download all the historical charts of all the companies listed in nse since it's begining till date?rama
OK, I'll bite.
When did the NSE begin?
I guess you have two options (going on available data for the ASX in Australia).
Find a data provider that supplies EOD by the day (week, month or year) and do lots of downloads - but you won't have the benefit of companies that have been renamed or had their code changed.
(NOTE. This will probably leave you with lots of data that is no longer relevant because companies have changed or delisted.
Buy a disc with all historical data on it. (Use Google to find them for the NSE - if they exist.)
