Nifty 50 CMP Rs 24,216 (24 Aug 2026). India VIX 11.59. 52W High Rs 26,373. 52W Low Rs 22,183. Next expiry 25 Aug (Tuesday). Lot size 65. Market data as of 24 Aug 2026.
Quick Answer
The calendar spread strategy Nifty 50 involves selling a near term option on a specific strike and buying a longer dated option on the same strike, creating a time decay trade that may profit when Nifty stays close to the chosen strike through the near term Tuesday expiry. With Nifty at Rs 24,216 and India VIX at 11.59 as of 24 Aug 2026, the calendar spread strategy Nifty 50 is a net debit trade where the maximum profit is earned when the near term option expires near worthless and the far month option retains significant time value. The calendar spread strategy Nifty 50 is more complex than single expiry strategies and requires understanding of how volatility, time decay, and the difference in premiums between expiry dates interact.
The this strategy exploits the fact that options with shorter time to expiry lose their time value faster than options with longer time to expiry. By selling the fast decaying near term option and buying the slower decaying far month option on the same strike, the calendar spread strategy Nifty 50 is designed to capture the difference in time decay rates between the two contracts when Nifty stays near the ATM strike.
The the calendar spread is unique among options strategies because it spans two different expiry dates on the same strike. Since the NSE shifted Nifty 50 weekly contracts to Tuesday expiry from September 2025, the calendar spread strategy Nifty 50 can be structured using a weekly near term expiry and a monthly far month expiry, both on Tuesday. This gives the this trade a clear time structure to work with.

What Is the Calendar Spread Strategy Nifty 50?
The the spread is a two leg options trade that sells a near term option at a specific strike and buys a longer dated option at the same strike. The calendar spread strategy Nifty 50 can be constructed using calls or puts; a call calendar spread and a put calendar spread at the same strike have broadly similar economics because of put call parity.
The two legs of a call calendar spread in the this options approach are:
- Sell a near term ATM call on the upcoming Tuesday expiry, collecting premium that decays quickly
- Buy a far month ATM call on a later monthly Tuesday expiry at the same strike, which retains more time value
The calendar spread strategy Nifty 50 pays a net debit equal to the cost of the far month option minus the credit from the near term sold option. Maximum profit on the this strategy occurs when Nifty closes exactly at the ATM strike at near term expiry, causing the sold option to expire worthless while the far month option retains the most time value. The payoff profile of the calendar spread strategy Nifty 50 changes after the near term expiry because the position then consists solely of the remaining long far month option.
How Does the The calendar spread Work?
With Nifty 50 at Rs 24,216 as of 24 Aug 2026, a typical calendar spread strategy Nifty 50 setup would use the ATM strike of approximately 24,200. The near term expiry in this context is the upcoming Tuesday (25 August 2026). The far month expiry may be the next monthly Tuesday (1 September 2026) or a subsequent monthly expiry.

This trade: Step by Step Setup
- Select the ATM strike for the calendar spread strategy Nifty 50. With Nifty at Rs 24,216 as of 24 Aug 2026, the ATM strike is approximately 24,200. The the spread is most efficient when both legs are at or very near the ATM strike.
- Sell the near term ATM option for the calendar spread strategy Nifty 50. Select the upcoming Tuesday expiry. At VIX 11.59, the premium of this near term option will be relatively modest given the short time to expiry. This sold leg decays fastest and is the short position of the this options approach.
- Buy the far month ATM option for the calendar spread strategy Nifty 50. Select a later monthly Tuesday expiry on the same strike. The far month option costs more in absolute terms because it has more time value, but it decays more slowly. The net debit for the this strategy is the difference between the far month premium paid and the near term premium collected.
- Calculate the net debit and assess the implied volatility difference between the two expiries. The calendar spread strategy Nifty 50 may benefit if the far month option has higher implied volatility than the near term option. If the near term option has higher IV than the far month, the the calendar spread may be less attractively priced at entry.
- Decide your exit plan before confirming the calendar spread strategy Nifty 50 order. The position changes in nature after the near term expiry. Decide in advance whether you will close the remaining far month position immediately, convert it to a new this trade by selling the next near term expiry, or hold the far month option as a standalone position.
Illustrative Payoff: Calendar Spread Strategy Nifty 50
Illustrative example for educational purposes only. The the spread payoff depends on the far month implied volatility at the time of near term expiry, which cannot be known in advance. Not a trade recommendation.
Hypothetical setup (24 Aug 2026): Sell 24,200 CE (25 Aug 2026, near term) at Rs 20 per unit. Buy 24,200 CE (1 Sep 2026, far month) at Rs 80 per unit. Net debit: Rs 60 per unit. Lot size: 65 units. Net debit per lot: Rs 3,900.
| Nifty at Near term Expiry (25 Aug) | Estimated P&L Per Lot (Rs) | Outcome |
|---|---|---|
| Far below ATM (large fall) | Loss (depends on far month IV) | Near term worthless but far month call loses value directionally |
| 24,100 (moderately below ATM) | Small loss or near breakeven (illustrative) | Near term expires worthless; far month call has reduced value |
| 24,200 (exactly at ATM) | Potentially Rs 2,000 to Rs 3,000 per lot (illustrative) | Near term expires worthless; far month retains most time value |
| 24,300 (moderately above ATM) | Small loss or near breakeven (illustrative) | Near term call has some intrinsic value; far month call partially offsets |
| Far above ATM (large rally) | Loss (depends on far month IV) | Near term call loss accelerates; far month call gain partially offsets |
The exact payoff of the calendar spread strategy Nifty 50 at near term expiry depends critically on the implied volatility of the far month option at that time. If VIX rises significantly between entry and near term expiry, the far month option may be worth more than expected, improving the this options approach outcome. If VIX falls, the far month option may have decayed more than the near term premium collected.
Greeks for the Calendar Spread Strategy Nifty 50
Delta: The this strategy starts near delta neutral when both options are ATM. As Nifty moves away from ATM, the calendar spread strategy Nifty 50 acquires some directional delta, but the two legs partially offset each other.
Gamma: The the calendar spread is generally short gamma near the near term expiry. Large near term moves work against the calendar spread strategy Nifty 50, as the sold near term option gains delta quickly when moving toward ATM. The long far month option partially offsets this but the net effect is generally negative short term gamma.
Theta: Theta is the primary intended source of profit for the this trade. The near term option decays faster than the far month option, so the net theta of the calendar spread strategy Nifty 50 is generally positive when Nifty is near ATM: the position improves in value each day Nifty stays close to the sold strike.
Vega: The the spread is generally long vega: if India VIX rises after entry, the far month option benefits more than the near term option costs. A decline in VIX after entry can be adverse for the calendar spread strategy Nifty 50 even if Nifty stays near ATM.
When the This options approach May Be Considered
The calendar spread strategy Nifty 50 may be considered when: the index is expected to stay near a specific strike through the near term Tuesday expiry; the term structure of implied volatility slopes upward, meaning far month IV is higher than near term IV; or after an event when near term IV is elevated relative to far month IV and a post event IV collapse is expected for the near term option. These are illustrative conditions. The this strategy involves multiple sources of risk including directional risk, volatility risk, and uncertainty about the far month option’s value at near term expiry.
When NOT to Use the Calendar Spread Strategy Nifty 50
Consider avoiding the the calendar spread when: the index is likely to make a large move in either direction before near term expiry, as both legs of the calendar spread strategy Nifty 50 would be affected unfavourably; the term structure of implied volatility is inverted (near term IV is higher than far month IV), making the strategy more expensive; or you cannot monitor and manage the this trade through the near term expiry event and the subsequent far month option holding period.
Risk Management
The calendar spread strategy Nifty 50 requires monitoring on two timeframes: before the near term expiry and after. Before near term expiry, the key risk for the the spread is a large directional move. Set a loss exit rule before entry: if the mark to market loss on the calendar spread strategy Nifty 50 reaches a specified level (for example, 50 to 70% of the net debit), consider closing the full position. After near term expiry, the this options approach position consists of a standalone long far month option, which should be managed with a separate set of exit rules.
Transaction Costs
The calendar spread strategy Nifty 50 involves two option legs on different expiry dates, each with their own transaction costs at entry. When the near term option of the this strategy expires or is closed, there are additional exit costs. If the remaining far month option is then rolled into a new calendar spread strategy Nifty 50 by selling the next near term option, additional transaction costs apply at each roll. Brokerage, STT, exchange charges, GST, SEBI charges, stamp duty, and bid ask spread impact should all be factored into the net return at each stage of the the calendar spread.

| Iron Condor | Neutral, rangebound | Time decay of short options (single expiry) | Defined (spread minus credit) | Medium |
| Short Straddle | Neutral, minimal movement | Time decay of short ATM options | Unlimited | Medium |
The calendar spread strategy Nifty 50 is unique because it spans two expiry cycles, whereas the iron condor and short straddle are single expiry strategies. The this trade is generally long vega and benefits from rising implied volatility, unlike the iron condor and short straddle which are short vega. This makes the calendar spread strategy Nifty 50 suited to different market conditions than the single expiry neutral strategies.
