What is the lot size of Tata Steel (TATASTEEL), and what is one contract worth at today's price?
As of 15:40 IST on 28 Oct 2026, Tata Steel (TATASTEEL) lot size for the 23 Nov expiry is 2,750 shares. At a spot price of 168.79, one contract is worth ₹4,64,173. 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 Tata Steel (TATASTEEL) options expire?
Stock options on NSE have monthly expiries only — there are no weekly contracts on individual stocks. The Tata Steel (TATASTEEL) 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 Tata Steel (TATASTEEL) options settled at expiry?
Stock options on NSE are physically settled. An in-the-money Tata Steel (TATASTEEL) option held to expiry becomes a delivery obligation: a long Call or a short Put means you take delivery of TATASTEEL 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 Tata Steel (TATASTEEL) options?
Buying a Tata Steel (TATASTEEL) 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.
