Based on Option Chain’s ‘OI’ (Open Interest) data there are many trading strategies available. So, Option Chain’s ‘OI’ data provided by NSE must be interpreted correctly.
Simply, open same instrument’s Option Chain data from above two websites.
Now compare (1st & 2nd) their ‘OI’ & “Chng in OI” data. You will see different values are there under ‘OI’ & “CHNG IN OI” data at New NSE (Beta) Website.
Which one is correct?
Option Chain’s OI based strategies will not work properly if data is interpreted wrongly.
Which OI data source should be treated as authentic?
I think it is F&O Bhabcopy at EOD. Am I right?
I am attaching 2 screenshots to make it easy the verification process. I have selected NIFTY, Expiry Date 31OCT2019 Option Chain from both the websites. Now see, ‘OI’ and “CHNG IN OI” values are different in New NSE (Beta) Website for the same Strike Price. But, I think this should not be.
Friends, please verify, you also see the same anomalies from your computer or not; or my computer gets hacked!
If you verify the presence of same anomalies, then we must let it know to New NSE Website Developers to make the necessary corrections.
