Nifty Futures Trading: Margin, Expiry and Settlement

Updated 5 November 2026 · Standard formula, shown below

Nifty futures are exchange-traded contracts whose value follows the Nifty 50 index; margin is the collateral required to carry a position, expiry is the contract’s final trading date, and settlement is generally cash-based. The exact margin and contract details can change, so check the exchange and broker information for the specific contract before placing a trade.

What Nifty futures are

A Nifty futures contract gives a trader exposure to changes in the Nifty 50 index at a future date, without requiring ownership of the index’s constituent shares. Futures are standardized and traded on an exchange. Each contract represents a specified quantity, or lot size, of the index, set under exchange rules.

Because the index itself cannot be delivered like a share, Nifty index futures are settled in cash rather than by delivering a basket of stocks. A futures position can be opened to speculate on a rise or fall, or to hedge some other exposure. Both uses carry risk: a small index move can create a substantial gain or loss relative to the margin deposited.

How margin works

Margin is not a down payment that caps your loss. It is collateral held against the obligations that arise from an open futures position. The exchange’s risk framework and the broker’s collection practices determine how much must be available. Requirements may change with market conditions, volatility, position size, and applicable rules.

Initial margin: the amount required to establish or carry a position, including applicable risk-based requirements.
Variation or mark-to-market amount: gains and losses are calculated as prices move. Losses can reduce available funds and may require additional funds.
Broker requirements: a broker may require more funds than the exchange minimum, and may set its own deadlines or procedures for a shortfall.

For a simple illustration, suppose the index futures price is 22,000 and the contract lot size shown by the exchange is 25. The notional exposure of one contract is 22,000 × 25 = ₹550,000. That is the contract’s approximate exposure, not the margin amount. The actual margin must be checked for that contract and date; it cannot be reliably inferred from the notional value alone.

If the futures price moves 100 index points against a one-lot position with a lot size of 25, the mark-to-market loss is 100 × 25 = ₹2,500, before charges and any other adjustments. This example shows why a trader should consider exposure and possible losses, not just the cash initially posted.

Expiry dates and contract choice

Futures are listed in contract months, commonly including near-month, next-month, and far-month contracts. Each has its own expiry date and price. The exchange specifies the current expiry schedule and may revise contract specifications, so do not assume a date based on an old calendar or a remembered weekday.

Choosing a contract involves more than selecting the nearest expiry. Consider:

Time to expiry: a near-month contract expires sooner; a later contract provides more time but may trade at a different price.
Liquidity: trading volume and bid-ask spread affect how easily a position can be entered or exited. Liquidity can differ among contract months.
Price relationship: futures prices can differ from the spot index because of factors such as financing costs, expected dividends, and time remaining. The difference is not a guaranteed profit.
Position and risk capacity: the contract’s notional exposure and potential loss should fit the trader’s risk plan and available funds.

Before trading, verify the symbol, contract month, lot size, expiry date, and applicable trading hours in the exchange’s current contract information. A similar-looking symbol can refer to a different instrument or expiry.

Settlement and what happens at expiry

Nifty index futures are cash-settled. There is no delivery of Nifty 50 shares when the contract expires. Open positions are settled using the exchange’s prescribed final settlement process and reference value. Any final profit or loss is accounted for in cash under the exchange and clearing arrangements.

Settlement does not mean that a trader can ignore an open position until the last moment. A trader may close a position before expiry by taking the opposite trade in the same contract. If it remains open, it proceeds through the exchange’s expiry and settlement process. The applicable final settlement price and timetable should be confirmed in current exchange rules.

Daily mark-to-market settlement also matters before expiry. Futures gains and losses are regularly accounted for, so a losing position can create a cash obligation while it is still open. A trader who cannot meet a margin call may have a position reduced or closed by the broker under its terms. This can happen before expiry and at a price that is not the trader’s preferred exit price.

Costs, risks, and common mistakes

Margin is only one part of the cost and risk picture. Trading can involve brokerage, exchange and clearing charges, taxes or levies where applicable, and bid-ask spread. The exact charges depend on the account, transaction, and current rules; consult the broker’s published schedule and relevant official sources rather than relying on a generic estimate.

Confusing margin with maximum loss: losses can exceed the margin set aside. A futures position does not have the limited-loss structure of a purchased option.
Using an outdated lot size or expiry calendar: contract specifications can change. Verify current details for the selected contract.
Ignoring mark-to-market cash needs: a position can require additional funds before the trader’s planned exit date.
Holding through expiry unintentionally: check open positions and broker cut-off procedures as expiry approaches.
Assuming futures and spot prices are identical: they can differ, and the difference can change over time.

Futures are leveraged instruments and are not suitable for every trader. Understand how losses are calculated, how margin calls are handled, and what happens if funds are unavailable before entering a position.

Frequently Asked Questions

Is Nifty futures settlement physical or cash?
Nifty index futures are settled in cash. The contract does not deliver the shares in the Nifty 50 index.

Does the margin amount stay fixed?
No. It can vary with exchange requirements, market risk, contract details, and broker policies. Check the current margin for the specific contract before trading.

Can I lose more than the margin deposited?
Yes. Margin is collateral, not a cap on losses. An adverse move can create losses beyond the amount initially posted.

Can I close a Nifty futures position before expiry?
Usually, a position can be closed by taking the opposite trade in the same contract while it is available for trading. Liquidity and trading hours affect execution.

What happens if I still hold a contract at expiry?
The open contract goes through the exchange’s cash settlement process. The final amount is based on the applicable settlement calculation and rules; confirm the current timetable and method with official contract information.

Where can I check the current lot size and expiry?
Use the exchange’s current contract specifications and expiry calendar, and verify that your broker’s order screen shows the same instrument and contract month.
