Wrong OI in option chain data

I was fetching option chain data for NSE Nifty 50. It is giving other informations correct except the open interest. It is not matching with nse website or other websites. I think there is error in the API.

Hi @Abhishek_47811438, could you share the time when you encountered this issue? This will help us investigate it further.

Thanks!

I just tried now. it is coming same. my call was 27-03-2025 expiry nifty 50 nse . I checked strike price 18000 for example. error is ithere for all strike price. see the difference in screenshot.


see the difference

Now I get it. In NSE site OI is shown divided by lot size. Whereas here we are getting direct count. Please confirm

@Abhishek_47811438 you are correct, we give OI in multiple of lot size you can verify the same on our pro web option chain also.

Thanks!
