Recently there was a minor tweak in this policy for futures and short options positions. But higher margins are still required for long options positions. The increase in margin starts 4 days before expiry as NSE (NCL/CMPT/43262) mandates it -
| Day (BOD-Beginning of the day) | Margins applicable |
|---|---|
| E-4 Day (Friday BOD) | 10% of VaR + ELM +Adhoc margins |
| E-3 Day (Monday BOD) | 25% of VaR + ELM +Adhoc margins |
| E-2 Day (Tuesday BOD) | 45% of VaR + ELM +Adhoc margins |
| E-1 Day (Wednesday BOD) | 70% VaR + ELM +Adhoc margins |
