Nifty 50 level used in this article: Rs 24,216 (as of 24 Aug 2026). Next weekly (Tuesday) and monthly (last Tuesday of the month) expiry: 25 August 2026 (Tuesday). Lot size 65. Nifty 50 retained its weekly expiry slot on NSE under SEBI’s one weekly index per exchange rule; Bank Nifty, Nifty Financial Services, and Nifty Midcap Select lost their weekly contracts instead, in November 2024. Both weekly and monthly Nifty 50 contracts remain available.
Quick Answer
The butterfly spread Nifty 50 is a three strike, four leg options strategy that combines a bull call spread and a bear call spread sharing a common middle strike, creating a payoff that peaks when Nifty 50 closes exactly at the centre strike at the monthly expiry. With Nifty 50 at Rs 24,216, the butterfly spread Nifty 50 costs a small net debit at entry, which is the maximum loss, while the maximum profit is concentrated in a narrow zone around the centre strike. The butterfly spread Nifty 50 may be considered when a trader has a precise view that the index will pin near a specific level by the monthly expiry.
The this strategy differs from the iron condor in an important way: rather than offering a wide profit zone between two short strikes, the butterfly spread Nifty 50 concentrates its maximum profit in a narrow band around a single centre strike. This makes it a higher precision, generally lower cost strategy, but one that requires the index to land close to a specific level rather than simply staying within a broader range.
Because Nifty 50 only trades monthly contracts, the the position requires the index to be near the chosen centre strike specifically at the monthly expiry, which is a longer and less certain prediction window than a Nifty 50 weekly butterfly would require.

What Is the Butterfly Spread Nifty 50?
The this trade uses three strikes and four option legs, all on the same monthly expiry. It can be constructed with calls or puts; a call butterfly is the more commonly used version.
The four legs of a call butterfly spread Nifty 50 are:
- Buy one call at the lower strike
- Sell two calls at the middle (centre) strike
- Buy one call at the higher strike
The lower and higher strikes are equidistant from the centre strike. The net debit paid is the maximum loss for the this options approach, and the maximum profit is realised when the index closes exactly at the centre strike at the monthly expiry, though a meaningful profit zone exists around that centre point as well.
How Does the Butterfly Spread Nifty 50 Work?
With Nifty 50 at Rs 24,216, a the spread might use 24,050 as the lower strike, 24,200 as the centre strike, and 24,350 as the higher strike, all equidistant. The position profits most if Nifty 50 closes very close to 24,200 at the monthly expiry.

Butterfly Spread Nifty 50: Step by Step Setup
- Identify the centre strike for the this strategy. With Nifty 50 at Rs 24,216, a centre strike near the current ATM level of 24,200 is common, though the centre strike can also be placed away from ATM to express a specific directional pinning view.
- Select the equidistant lower and higher strikes. The distance between the centre strike and each outer strike, referred to as the wing width, determines both the maximum profit and the net debit required for the butterfly spread Nifty 50.
- Buy one lower strike call, sell two centre strike calls, buy one higher strike call. All four legs of the butterfly spread Nifty 50 should be placed together, ideally as a single combined order to minimise legging risk.
- Calculate the net debit and maximum profit. Maximum profit for the butterfly spread Nifty 50 equals the wing width minus the net debit, multiplied by 65 units, realised at the centre strike.
- Set an exit plan before confirming the butterfly spread Nifty 50 order. Because maximum profit is concentrated in a narrow zone, decide in advance whether you will hold to expiry or take a partial profit if the index approaches the centre strike before then.
Illustrative Payoff: Butterfly Spread Nifty 50
Illustrative example for educational purposes only. Strikes, premiums and calculations are hypothetical and should not be interpreted as a trade recommendation.
Hypothetical setup: Buy 24,050 CE, sell two 24,200 CE, buy 24,350 CE. Net debit: Rs 70 per unit. Lot size: 65 units. Wing width: 150 points.
| Nifty 50 at Monthly Expiry | P&L Per Unit (Rs) | P&L Per Lot (65 units, Rs) | Outcome |
|---|---|---|---|
| At or below 24,050 | -70 | -4,550 | Max loss; all calls expire worthless or offset |
| 24,200 (centre strike) | +80 | +5,200 | Max profit |
| At or above 24,350 | -70 | -4,550 | Max loss; wings fully offset |
The butterfly spread Nifty 50 profit zone narrows sharply away from the centre strike. Unlike the iron condor’s wider plateau, the butterfly spread Nifty 50 payoff peaks at a single point and declines on either side, reaching maximum loss at or beyond the outer wing strikes.
Greeks for the Butterfly Spread Nifty 50
Delta: The butterfly spread Nifty 50 is close to delta neutral when the index is at the centre strike, developing directional delta as the index moves toward either wing.
Gamma: The butterfly spread Nifty 50 carries negative gamma near the centre strike as expiry approaches, meaning the position becomes more sensitive to further movement precisely at the point where the trader wants the index to stay pinned.
Theta: Theta is generally positive for the butterfly spread Nifty 50 when the index is near the centre strike, since the two short options at that strike decay faster than the two long wing options.
Vega: The butterfly spread Nifty 50 is generally short vega near the centre strike, meaning a rise in implied volatility after entry tends to work against the position if the index is trading near that strike.
When the Butterfly Spread Nifty 50 May Be Considered
The butterfly spread Nifty 50 may be considered when a trader has a specific view that the index will pin near a particular level by the monthly expiry, often based on options derived reference points such as max pain, or when implied volatility is elevated and expected to decline as the index consolidates toward a specific level.
When NOT to Use the Butterfly Spread Nifty 50
Consider avoiding the butterfly spread Nifty 50 when you have only a general rangebound view rather than a specific target level, in which case an iron condor’s wider profit zone may be more appropriate; the index is likely to trend strongly in one direction; or the wing strikes available do not offer an attractive net debit relative to the potential profit.
Risk Management
The butterfly spread Nifty 50 has defined risk limited to the net debit paid. Because the profit zone is narrow, many traders consider taking partial profits if the index approaches the centre strike before expiry, rather than holding for the theoretical maximum, which requires landing very close to that exact level.
Transaction Costs
The butterfly spread Nifty 50 involves four separate option legs, which can mean higher cumulative transaction costs relative to the typically modest net debit paid. Brokerage, exchange transaction charges, STT, GST, SEBI charges, stamp duty, and bid ask spread impact across four legs should be weighed carefully against the potential profit.

Conclusion
The butterfly spread Nifty 50 is a defined risk strategy suited to a precise view that the index will pin near a particular level by the monthly expiry, offering a typically lower net debit than a comparable iron condor in exchange for a narrower profit zone. Because Nifty 50 only trades monthly contracts, this pinning view must hold over a full month rather than a single week. Always verify current lot size (65 units from January 2026) and expiry schedule on NSE before executing any trade.
