It is not a bug, the options chain you are using on ot.dhan.co is compact version. There limited column available for the compact options chain. To view more column, click for Advanced Options Chain from the top right corner. You will see more column options like greeks, IV etc
@Naman, Thank you for your warm wishes and for acknowledging my post.
My concern is not with the number of columns in the compact version. I am concerned with the call-side LTP column data.
If you carefully observe and compare it with the put-side LTP data then you will find that the LTP percentage changes are not populating properly for the few strike prices at call-side LTP.
