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.
1st Go to Old NSE Website’s Option Chain link.
Select NIFTY Option Chain, Expiry Date 31-Oct-2019 or the one you like.
2nd Go to New (Beta) NSE Website’s Option Chain link.
Select NIFTY Option Chain, then select Expiry Date 31-Oct-2019 or the one you already liked.
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?
