For some reason I couldn’t get any of the Nifty or Bank nifty contract’s OI data on 6th of October 2025. I am receiving SENSEX’s OI data properly. Just Nifty and Bank Nifty is showing 0 for some reason. As you can see the in the screenshot, OI data is 0 but volume is changing. SENSEX’s data is showing OI. It was working perfectly fine on Friday (3rd Oct 2025). I tried downloading today’s data also, same error in Bank nifty and nifty but I am receiving SENSEX’s OI data.
