Iron Condor Strategy on Nifty: Strike Selection, Payoff, Margin and Adjustment Rules

An iron condor strategy on Nifty means selling an out-of-the-money put spread and an out-of-the-money call spread on the same expiry. You take in a net premium on day one and make money if the index stays inside a range until expiry. Investopedia describes it as a popular trade for people who want to profit from steady, low-volatility markets. The big attraction is that your maximum profit and maximum loss are both locked in the moment you enter. In this guide we cover how the four legs fit together, how to pick strikes on NSE’s Nifty contracts, a worked payoff example, the SEBI margin and expiry-day rules that apply, and the adjustment rules you should write down before placing the trade.

If calls, puts and premium are still new to you, begin with our pillar guide on options trading for beginners in India and the step-by-step options primer. An iron condor has four legs, and each should make sense to you on its own before the whole thing does.

How the iron condor strategy works on Nifty

Investopedia’s iron condor explainer breaks the trade into a bull put spread and a bear call spread. All four options are out of the money and expire on the same date:

• Bull put spread: sell a higher-strike put and buy a lower-strike put. This half keeps its credit as long as the index stays above the short put strike.
• Bear call spread: sell a lower-strike call and buy a higher-strike call. This half keeps its credit as long as the index stays below the short call strike.

The two short options mark the edges of the range you think Nifty will hold. The two options you buy, usually called the wings, sit further out and limit the damage if you’ve got it wrong. Because the short legs fetch more premium than the wings cost, the position opens for a net credit.

Per Investopedia, you hit maximum profit when the price stays between the short put and short call strikes and all four options expire worthless, so you keep the whole net credit. Maximum loss kicks in when the price moves past one of the long strikes. The breakevens come straight from the strikes:

• Lower breakeven = short put strike minus net premium received
• Upper breakeven = short call strike plus net premium received

On either side, maximum loss is the width of that spread minus the net credit. That’s what separates it from a short strangle, which sells the same two out-of-the-money options without buying wings, and so has no ceiling on losses.

An iron condor is a trade on how far Nifty will not move, not on which way it moves. You are paid a small, fixed credit for being right about the range and you accept a larger, but still fixed, loss if the range breaks.

Why Nifty suits a weekly iron condor

A condor needs liquid strikes on both sides and frequent expiries. Nifty has both. NSE’s Nifty 50 derivatives contract page lists four weekly expiry contracts and three consecutive monthly contracts, along with quarterly and half-yearly months. Monthly Nifty options expire on the last Tuesday of the expiry month and weeklies on every Tuesday of the expiry week. If that Tuesday is a trading holiday, expiry moves to the previous trading day.

Two other details on that NSE page shape how you build the trade. Nifty options are European style, marked CE and PE in the contract descriptor, so they can only be exercised at expiry. And for weekly and monthly contracts, NSE offers strikes at 50-point intervals at every index level, with 35 strikes in the money, one at the money and 35 out of the money. That spacing gives you precise control over how far out the short strikes go and how wide the wings are.

There’s less weekly choice than there used to be. SEBI’s October 1, 2024 circular on strengthening the equity index derivatives framework lets each exchange offer weekly-expiry derivatives on just one of its benchmark indices, effective November 20, 2024. Since NSE lists four weekly Nifty expiries, Nifty is the contract for a weekly iron condor on NSE. For how expiry weeks play out on the BSE side, see our report on Sensex weekly expiry flows.

Picking strikes for a Nifty iron condor

Strikes decide nearly everything: how much you collect, how often you win, and how much you lose when you don’t. Investopedia’s construction steps set out the basics. Place the short put and short call where the chance of finishing in the money is low, and put the long put and long call further out than the shorts. On Nifty, a workable approach looks like this:

1. Start with today’s level and the range you expect. Ask how far Nifty could realistically move before expiry. In a quiet market you can bring the short strikes closer and collect more; in a jumpy one, push them wider and accept a smaller credit. Our daily India VIX coverage gives a quick sense of whether options are pricing calm or trouble.
2. Keep both sides roughly even. Putting the short put and short call at a similar distance from the index keeps the trade neutral. Pull one side closer and you’ve added a directional lean, which we come back to in the adjustment section.
3. Decide the wing width. The gap between each short strike and its long strike sets your maximum loss. With 50-point strike intervals you can run wings of 100, 200 or more points. Wider wings bring in a little more credit but raise the maximum loss per unit.
4. Choose the expiry. Investopedia notes that options with up to two weeks left lose time value much faster but are more exposed to sudden moves, while options with 60 or more days to go decay more slowly and react more to changes in volatility. Weekly Nifty condors sit right at the fast-decay, high-gamma end.
5. Stick to liquid strikes. Investopedia points out that traders favour liquid options with tight bid-ask spreads and high open interest. With four legs, a wide spread on each one adds up fast, so check the option chain for depth at all four strikes before you commit.

Iron condor payoff: a worked Nifty example

These numbers are made up purely to show the arithmetic. They aren’t live quotes or a recommendation. Say Nifty is at 22,600 and you set up a weekly iron condor with 200-point wings:

You collect ₹40 plus ₹38, which is ₹78, and pay ₹22 plus ₹20, which is ₹42. That leaves a net credit of ₹36 per unit, and that’s your maximum profit. Each spread is 200 points wide, so maximum loss is 200 minus 36, or ₹164 per unit. Plugging into the formulas above, the lower breakeven is 22,200 minus 36, or 22,164, and the upper breakeven is 23,000 plus 36, or 23,036. To turn any per-unit figure into rupees per lot, multiply by the lot size in force for that contract, which NSE publishes for each series.

Two things jump out. The trade wins across a wide band, 22,164 to 23,036 here, which is why condors feel comfortable most weeks. But the reward-to-risk is badly skewed: you’re putting ₹164 at risk to make ₹36. One full loss wipes out the profit from more than four winning weeks. Investopedia’s own example has the same shape, with a trader risking $300 to make $200 on a US ETF condor. In our Nifty example, with short strikes further out of the money, the gap is even wider.

The high win rate of an iron condor comes bundled with a poor reward-to-risk ratio. The strategy only works over time if the losing weeks are kept smaller than the maximum loss.

Margin and SEBI expiry-day rules for iron condors

Since all four legs share one expiry and the wings cap the loss, an iron condor is a hedged position. Investopedia counts lower capital needs compared with other options spreads among its advantages. The exact margin, though, depends on how your broker calculates the full four-leg basket. Enter all four legs in your broker’s margin calculator and check the combined figure before you place the order.

Several measures in SEBI’s October 2024 circular, which you can read in full in the circular PDF, change how condors are run in practice:

• Upfront premium for bought options. Since February 1, 2025, brokers have to collect the net options premium payable from option buyers upfront. So the wings you buy need cash in the account at entry.
• Extra margin on expiry day. Since November 20, 2024, an additional extreme loss margin of 2% applies to short options contracts on their expiry day. It covers short options open at the start of the day as well as those opened during it. Carry a weekly condor’s short legs into Tuesday’s expiry and expect a bigger margin block that day.
• Contract size. For new contracts introduced after November 20, 2024, SEBI set the minimum value of an index derivative contract at ₹15 lakh at introduction, with lot sizes fixed so the contract value falls within ₹15 lakh to ₹20 lakh on the day of review. Every lot of a condor is a large notional position.
• Intraday position limits. Since April 1, 2025, exchanges have monitored index derivatives position limits during the day, not only at the close.

The same circular dropped calendar spread margin benefits on expiry day for positions mixing different expiries. A standard condor uses a single expiry, so this mostly matters if you combine a condor with other expiries, a structure covered in our calendar spread options strategy guide.

Adjustment rules for a Nifty iron condor

Investopedia notes you can shift strikes to give a condor a bullish or bearish lean. A bullish condor brings the put spread closer to the index and widens the call side. That raises the credit if the market rises or goes nowhere, but adds downside risk. A bearish condor flips it, pulling the call spread closer and pushing the put spread further out. That’s a decision you make at entry. Once you’re in the trade, the questions are different, and it really helps to have your answers written down beforehand.

• Set a loss limit in rupees. Pick the loss at which you’ll close the whole position, say a multiple of the credit you took in, and act on it when it’s hit instead of hoping for a turnaround.
• Define a tested side. A side is under pressure when Nifty drifts toward its short strike. You can close the tested spread and keep the other, or roll the untested spread closer to the index for extra credit, which also shrinks your profit range.
• Book profits before expiry. Time decay helps you as expiry approaches, but a late swing in Nifty can wipe out gains just as fast. Taking a planned slice of the maximum profit early, instead of waiting for the last rupee, cuts your exposure to a late move and to the expiry-day margin bump above.
• Don’t pile risk onto a losing condor. Rolling a losing side over and over can turn a defined-risk trade into an open-ended one.
• Size every trade on its maximum loss. Treat the full maximum loss per lot as your money at risk and size with a rule like fixed fractional position sizing. Our guide to risk management in trading goes deeper on stops and drawdown limits.

Iron condor pros and cons

Investopedia lists limited risk, a high probability of profit, flexibility and lower capital needs as the pros, and limited reward, possible assignment and a very negative impact from rising volatility as the cons. On Nifty, the European-style contracts NSE lists mean the short legs can only be exercised at expiry, so early assignment isn’t the worry it is with US stock options. The volatility risk is still very much there.

Before you put on your first condor

Defined risk isn’t the same thing as low risk. SEBI’s September 2024 press release on F&O trader losses found that 93% of over 1 crore individual equity F&O traders lost money between FY22 and FY24, around ₹2 lakh per trader on average including transaction costs, and that individual traders’ combined losses topped ₹1.8 lakh crore over the three years. Only 1% of individual traders made more than ₹1 lakh in profit after transaction costs.

A condor won’t change those odds by itself. What it does is show you the risk of each trade before you take it. If you trade one, write down the range you expect, the strikes and wings, the maximum loss per lot, the level at which you’ll get out and how you’ll handle expiry day. Then size it so a full maximum loss is a setback, not a disaster.
