The Delta in an Option Chain does not change with the change in the underlying (Nifty 50 or Nifty Bank as I refer to these chains). The Delta should change with the change in the Gamma value with the change in the underlying. I see them changing on other broker platforms.
We checked and found that the delta is updating as soon as we receive the data. As of now, you will have to refresh the page to see the most recent greeks value.

Do I need to refresh the page every time to see the latest value of the Delta?
I believe that with every change in the underlying, the Gamma changes, and with that, the Delta should change. So, since the value of the underlying changes every microsecond, the delta shall also change accordingly. Meaning, we should see the frequency of change in the Delta same as the frequency of change in the Premium column.
