Options trade only in whole lots, so premium × lot size is the rupee cost of one lot. NSE revises stock lot sizes from time to time, so confirm it before you place an order.
When do IDFC First Bank (IDFCFIRSTB) options expire?
Stock options on NSE have monthly expiries only — there are no weekly contracts on individual stocks. The IDFC First Bank (IDFCFIRSTB) expiry shown on this chain is 23 Nov 2026. Three monthly expiries trade at a time — near, next and far month — and the expiry selector above the chain switches between them. Time value decays fastest in the final days, so near-month premiums fall quickly as expiry approaches.
How are IDFC First Bank (IDFCFIRSTB) options settled at expiry?
Stock options on NSE are physically settled. An in-the-money IDFC First Bank (IDFCFIRSTB) option held to expiry becomes a delivery obligation: a long Call or a short Put means you take delivery of IDFCFIRSTB shares and pay their full value, while a long Put or a short Call means you deliver the shares. Out-of-the-money options expire worthless. To avoid delivery, square off or roll the position before expiry.
How much margin do you need to trade IDFC First Bank (IDFCFIRSTB) options?
Buying a IDFC First Bank (IDFCFIRSTB) Call or Put needs only the premium — option price × lot size, paid upfront. Selling (writing) an option needs SPAN plus exposure margin set by the exchange, which is usually far larger than the premium because the seller's risk is open-ended. In-the-money positions also attract additional delivery margin in the last few days before expiry, because stock options settle by physical delivery.
