Price Band A contract specific price range based on its delta value computed and updated on daily basis.

Initial Margin Initial Margin would be calculated using SPAN; the margining framework of India ICC shall be compliant with the PFMI including a margin model that provides coverage of at least a 99% single-tailed confidence interval of the estimated distribution of future exposure.

Calendar Spread Margins The margin for options calendar spread would be the same as specified for futures calendar spread. The margin would be calculated on the basis of delta Δ of the portfolio in each month. A portfolio consisting of a near month option with a delta Δ of 100 and a far month option with a delta Δ of –100 would bear a spread charge equal to the spread charge for a portfolio which is long 100 near month futures and short 100 far month futures

Mark-to-Market (MTM) Settlement NA
Premium Quoted in US Dollar
Option Type Premium Style European Call and Put Options
Strike Price Intervals Minimum 10 strikes at strike increment above and below the at-the-money strike.
Once the settlement price reaches close to the lower end or higher end of the option chain, additional option strikes will be introduced.
Short Option Minimum Margin Deep-out-of-the-money short options may show zero or minimal Scan Risk given the price and volatility moves in the 16 market scenarios, yet still present risk in the event that these options move closer-to-the-money or in-the-money, thereby generating potentially large losses. Hence a Short Option Minimum Margin is applied to each product to account for this potential exposure. The Short Option Minimum Margin is calculated on the Notional Value of all short options.
Settlement of Premium Premium would be settled in $US and would be paid in by the buyer in cash and paid out to the seller in cash. Until the buyer pays in the premium, the premium due shall be deducted from the available liquid assets on a real time basis.
Net Option Value The Net Option Value is the current market value of the option times the number of options (positive for long options and negative for short options) in the portfolio. The Net Option Value would be added to the Liquid Net Worth of the clearing member. Thus, mark to market gains and losses would not be settled in cash for options positions.
Assignment Margin

Assignment Margin shall be levied on assigned positions of the clearing members towards exercise settlement obligations for option contracts. For option positions exercised, the seller of the options shall be levied assignment margins which shall be 100% of the net exercise settlement value payable by a clearing member towards exercise settlement. Assignment margin shall be levied till the completion of pay-in towards the exercise settlement. Assignment margins shall be computed as net of assignment settlement and futures final settlement.
