Calender Spreads in Futures

Hi,

I want to know what can be the reasons for increasing or decreasing the spreads between current month and near month futures.

I read about calender spreads on Zerodha Varsity.

NF Futres continuous chart which is determining when to execute calender spreads based on last 8 months of data.

Some more charts and literature on calender spreads:

Queries:

  1. I want to know what can be the reasons for increasing or decreasing the spreads between current month and near month futures.

  2. Will current month Fut contract requires additional margin on Day of Expiry for Calender Spreads as well, though it is hedged with Next month Future Contracts?

Margin Policy: What is Zerodha's policy on the physical settlement of equity derivatives on expiry?

Our margin policy

E-4 Day (Friday) 10% of VaR + ELM +Adhoc margins
E-3 Day (Monday) 25% of VaR + ELM +Adhoc margins
E-2 Day (Tuesday) 45% of VaR + ELM +Adhoc margins
E-1 Day (Wednesday) 25% of the contract value
Expiry Day (Thursday) 50% of the contract value
