Short answer

You can view commodity contract details such as lot size, expiry rules, settlement method, and timelines on the Info widget on Arrow.

To access the widget:

Click on any MCX contract in your watchlist.

Select Info from the context menu.

You can navigate different expiries of futures and options for that particular instrument by clicking on the expiry date.
