Can anyone suggest that in calendar spread strategy between near month and next month of NIFTY futures, how much is the spread difference on the expiry of the futures contract? I have seen it ranges from 48 points and on expiry it is nearly 20 points. Is it valid?

Empirically yes, 20-40 point range between current month and mid month seems valid.

Thanks Mr. Karthik for suggesting. So it would be quite good if i make a spread at 40-45 points and on expiry it is down to 20 points nd i make sum 20 points profit from it. Can u suggest some more scrips across various segments where there would be some opportuinity of calender spreads.
