Nifty 50 Data from Zerodha (website) and NSE (website)

amitjet
Hi Zerodha Support team,

I have downloaded Nifty 50 Index data at 1 minute interval from your website using chartiq chart option.
i did the same from NSE https://www.nseindia.com/index-tracker/NIFTY 50 using their chart and exporting data as csv. they dont show ohlc, i assumed it is close value.

when i compare the close values minute by minute from zerodha and nse, they are not matching. What is this discrepancy? How to solve it?

keep in mind. this is NOT captured realtime. this was captured EOD from both sites.
