How the Mechanism Operates
In Indian derivatives trading, margins are determined dynamically by the Clearing Corporation using the Standard Portfolio Analysis of Risk (SPAN) algorithm.
SPAN recalculates portfolio risk 6 times every trading day based on live volatility, underlying price movement, and Greeks exposure. Under SEBI Peak Margin regulations, brokers must capture intraday margin snapshots at 4 random intervals. If a trader's account equity falls below the mandated peak margin requirement at any snapshot, a formal peak margin penalty is levied.
When holding overnight short futures or short options, adverse price movement results in an MTM cash debit. If free cash drops below maintenance requirements, the broker issues a 'Margin Call', requiring immediate funds deposit before 10:00 AM next morning or facing forced liquidation.
Margin Call Liquidation During Union Budget Volatility
A trader sold naked 24,000 PE and 25,000 CE utilizing 95% of their available margin before Budget day.
India VIX surged from 13 to 22. Even though Nifty remained within strikes, expanding SPAN volatility margin surged requirement by 45%.
Broker auto-squared off the position at a ₹65,000 loss due to margin shortfall, despite strikes expiring OTM two days later.
★ Never utilize more than 60% margin when entering positions before major high-volatility binary events.
