Futures contracts are standardized derivative instruments that obligate the buyer to purchase, and the seller to sell, a specific asset at a predetermined price on a future date. On the National Stock Exchange of India, futures are available on major indices like Nifty 50, Bank Nifty, and Fin Nifty, as well as on over 175 individual stocks. Futures trading offers leverage, hedging capabilities, and the ability to profit from both rising and falling markets, making it an essential instrument in the toolkit of active Indian market participants.
This guide covers everything you need to know about futures trading on NSE, from the mechanics of how futures work and margin requirements to advanced strategies for hedging and speculation.
How Futures Work on NSE
A futures contract on NSE specifies the underlying asset, the contract expiry date, and the lot size. Unlike options where the buyer has a right but not an obligation, futures create a binding obligation for both parties. When you buy (go long) a Nifty futures contract, you are obligated to buy the underlying at the futures price on expiry. When you sell (go short), you are obligated to sell at that price. In practice, most futures positions are squared off before expiry, with profit or loss settled in cash.
NSE offers futures contracts with three expiry cycles: near month, next month, and far month. The near-month contract has the highest liquidity and the tightest bid-ask spread, making it the preferred choice for most traders. On the last Thursday of each month (or the previous trading day if Thursday is a holiday), the near-month contract expires and is settled at the final settlement price based on the underlying index or stock price.
Each futures contract has a fixed lot size that determines the minimum quantity you can trade. For Nifty 50 futures, the lot size is 25 units, meaning one contract represents 25 times the index value. At a Nifty level of 24,000, one lot of Nifty futures represents a notional value of 6 lakh rupees. The lot size varies by stock, ranging from small lots for high-priced stocks to larger lots for lower-priced stocks, targeting a minimum contract value as specified by SEBI.
Margin Requirements
Futures trading uses leverage through the margin system. You do not need to pay the full contract value upfront. Instead, you deposit an initial margin, which is a percentage of the total contract value. NSE uses the SPAN (Standard Portfolio Analysis of Risk) margin system that calculates margin requirements based on the portfolio's overall risk, considering the volatility of the underlying asset and the potential loss in various market scenarios.
The initial margin for index futures typically ranges from 10 to 15 percent of the contract value, while for stock futures it ranges from 15 to 50 percent depending on the stock's volatility classification. In addition to the initial margin, exposure margin of 3 to 5 percent is required. This means that with approximately 1 lakh rupees in margin, you can take a position worth 5 to 7 lakh rupees in Nifty futures, providing 5 to 7 times leverage.
While leverage amplifies profits, it equally amplifies losses. A 5 percent adverse move in the underlying when using 5x leverage translates to a 25 percent loss on your margin capital. Mark-to-market settlements happen daily, meaning profits are credited and losses are debited at the end of each trading session. If your margin falls below the maintenance level, you will receive a margin call requiring additional funds.
Futures Trading Strategies
Trend Following
The most straightforward futures strategy is to go long when you expect prices to rise and short when you expect them to fall. Using technical analysis tools such as moving averages, trendlines, and momentum indicators, trend followers ride the dominant market direction. On Nifty futures, the 20-period EMA crossover with the 50-period EMA on the hourly chart is a popular trend following approach that captures multi-day moves while filtering out noise.
Spread Trading
Calendar spreads involve simultaneously buying and selling futures contracts on the same underlying with different expiry dates. For example, buying the near-month Nifty contract while selling the next-month contract creates a calendar spread that profits from changes in the spread between the two contract prices. This strategy has lower risk than outright directional trades and is popular among experienced Indian traders, particularly around rollover periods when the spread tends to normalize.
Hedging with Futures
Investors holding a portfolio of Indian stocks can hedge against market downturns by selling Nifty or sector-specific index futures. If you hold a diversified portfolio worth 10 lakh rupees, selling equivalent Nifty futures contracts protects your portfolio from broad market declines. The hedge ratio depends on the portfolio's beta relative to the index. Portfolio hedging is particularly valuable ahead of known risk events like elections, budget announcements, or global economic uncertainties.
Basis, Contango, and Backwardation
The basis is the difference between the futures price and the spot price. In normal market conditions (contango), futures trade at a premium to spot because of the cost of carry, which includes interest costs on the capital locked in the position. The premium typically decreases as expiry approaches and converges to zero on the expiry date. When futures trade below spot (backwardation), it signals bearish sentiment or high demand for short positions.
Monitoring the basis provides valuable insights into market sentiment. A widening premium often indicates bullish institutional positioning, while a narrowing or negative basis suggests institutional bearishness. Tracking the basis trend alongside open interest changes helps traders understand whether the smart money is accumulating long or short positions.
Rollover Analysis
As the near-month contract approaches expiry, traders who wish to maintain their positions must close the expiring contract and open a position in the next-month contract. This process, called rollover, happens in the last week before expiry. High rollover percentages indicate that market participants are maintaining their positions, suggesting trend continuation. Low rollover percentages may signal that traders are exiting positions, potentially foreshadowing a trend change.
On NSE, the rollover data for Nifty and Bank Nifty futures is closely watched by institutional and retail traders alike. A rollover above 75 percent at a premium is considered bullish, indicating that long positions are being carried forward with conviction. Rollover below 60 percent or rollover at a discount suggests bearishness. AI-powered analytics can track rollover patterns across hundreds of stock futures simultaneously, identifying conviction-backed positioning.
Risk Management for Futures Traders
Given the leveraged nature of futures trading, robust risk management is non-negotiable. Never use the maximum leverage available to you. A prudent approach is to use only 20 to 30 percent of the available leverage, keeping ample buffer for adverse moves and margin calls. Set strict stop-losses on every trade and honor them without exception.
Diversify your futures exposure across different underlying assets and avoid overconcentration in a single stock or sector. Monitor your overall portfolio delta (net directional exposure) to ensure it stays within your risk tolerance. During high-volatility events, consider reducing position sizes or moving to the sidelines entirely rather than trying to profit from unpredictable short-term moves.
