Iron
Condor

What is an iron condor?

An iron condor combines two credit spreads on the same underlying and expiry: a bear call spread placed above the current price and a bull put spread placed below it. By selling both spreads simultaneously, you collect a combined net credit that represents your maximum possible profit. The trade profits in full when the underlying stays inside the range defined by the two short strikes and all four options expire worthless.

The iron condor is the premium seller's answer to the short strangle: it generates similar range income but replaces open-ended risk with capped, defined-risk loss on each wing. On NSE, it is a mainstay of weekly NIFTY and Bank Nifty expiry cycles, where time decay accelerates sharply in the final days and options sellers can often place strikes at meaningful OI resistance and support levels.

Key takeaways

• An iron condor is a neutral, four-leg, net-credit strategy — you receive premium on entry and profit from range-bound price action.
• Max profit equals the total net credit received, realised when all four legs expire worthless between the short strikes.
• Max loss equals the spread width minus the net credit, occurring when the underlying expires beyond either long strike wing.
• There are two breakeven points: short put strike minus net credit, and short call strike plus net credit.
• Theta decay and falling implied volatility both accelerate profit, making the iron condor ideal in high-IV, range-bound conditions.

How it works

The call spread side (bear call spread) obligates you to deliver at the short call strike if the buyer exercises, capped above by the long call. The put spread side (bull put spread) obligates you to buy at the short put strike if exercised, capped below by the long put. Together they create a flat-topped profit tent between the two short strikes. Delta is near zero when the underlying is in the centre of the range — the condor has minimal directional bias — and gamma risk grows as the underlying approaches either short strike near expiry.

On NSE, NIFTY and Bank Nifty iron condors are cash-settled, removing physical delivery risk. The strategy benefits from IV crush — the compression of implied volatility that frequently follows high-uncertainty events like budget days, RBI policy announcements or earnings seasons. Placing the condor before the event and exiting after the IV collapse can generate a large portion of the theoretical max profit well before expiry. Open interest concentration at round numbers is often used on NSE to identify natural short-strike candidates.

The numbers that matter

Worked NIFTY example

Suppose NIFTY is near 22,500 and you expect it to remain between 22,200 and 22,800 through weekly expiry. You sell the 22,700 call for ₹65, buy the 22,900 call for ₹25, sell the 22,300 put for ₹55, and buy the 22,100 put for ₹20. Net credit = (65 − 25) + (55 − 20) = ₹40 + ₹35 = ₹75. Spread width = 200 points. With a lot size of 75, credit in hand = ₹75 × 75 = ₹5,625. Max loss = (200 − 75) × 75 = ₹125 × 75 = ₹9,375 (all figures hypothetical and for illustration only):

• Upper breakeven: 22,700 + 75 = 22,775.
• Lower breakeven: 22,300 − 75 = 22,225.
• Max profit: ₹5,625, if NIFTY expires between 22,300 and 22,700.
• Max loss: ₹9,375, if NIFTY expires above 22,900 or below 22,100.

NIFTY at expiry	Call spread P&L	Put spread P&L	Total P&L (1 lot)
21,900	+₹3,000	−₹12,375	−₹9,375
22,225 (lower BE)	+₹3,000	−₹3,000	₹0
22,500 (centre)	+₹3,000	+₹2,625	+₹5,625
22,775 (upper BE)	−₹2,625	+₹2,625	₹0
23,100	−₹9,375	+₹2,625	−₹6,750
23,200	−₹9,375	+₹2,625	−₹6,750

When to use it

• You expect the underlying to stay in a defined range through expiry — no strong trend either way.
• Implied volatility is elevated and likely to fall, enriching the credit you collect and accelerating the collapse of option prices.
• You want defined risk on both sides — the condor's capped loss makes it suitable for traders who cannot tolerate the open-ended exposure of a short strangle.
• You are in the final week of an expiry cycle where theta decay is sharpest and the range is easier to estimate from OI data.

Risks to respect

• Trend risk: a sustained directional move through a short strike converts the entire spread on that wing into max loss. Four legs do not help when the market trends.
• Gap events: overnight gaps driven by global cues, RBI, or Budget announcements can jump past a short strike before you can exit, locking in a large portion of the max loss instantly.
• Transaction costs: four-leg entry and exit multiplies brokerage and exchange charges; factor this into the net credit calculation, especially on weekly expiries.
• Gamma near expiry: gamma accelerates sharply in the final session — a small move in the wrong direction can swing the P&L dramatically when the short strike is nearly touched.

Iron condor vs short strangle

The short strangle sells a naked OTM call and a naked OTM put for a higher premium, but carries undefined risk — a gap or trend far outside the strikes produces losses with no floor. The iron condor adds long wings beyond each short strike to cap that risk. The trade-off: the condor collects less net credit because the long wings cost premium. For most NSE traders, the defined loss and significantly lower SPAN margin requirement of the iron condor make it the more practical structure, especially on index options where extreme moves are not uncommon.

Iron condor vs iron butterfly

An iron butterfly places both short strikes at the same at-the-money level, creating a much higher net credit but a very narrow profit zone. The iron condor widens the profit corridor by separating the short call and short put strikes, collecting less credit but requiring a smaller price move to win. The butterfly suits extreme low-volatility scenarios; the condor suits moderately low-volatility range-bound markets where the underlying could easily drift 1–2% without breaking out.

Frequently asked questions

When does an iron condor make money?

An iron condor profits when the underlying stays between the two short strikes through expiry. Maximum profit — the total net credit — is earned when all four options expire worthless and no settlement is owed on any leg.

What is the maximum loss on an iron condor?

Maximum loss equals the width of one spread (assuming both spreads are equal width) minus the total net credit received. It occurs when the underlying expires beyond either long strike — above the long call or below the long put.

How many breakevens does an iron condor have?

Two. The upper breakeven is the short call strike plus the net credit; the lower breakeven is the short put strike minus the net credit. The trade is profitable at expiry only when the underlying closes between these two levels.

What is the difference between an iron condor and a short strangle?

Both profit from a range-bound underlying, but a short strangle has undefined risk on both sides if the price moves far beyond either strike. An iron condor adds long wings to cap those losses, trading some of the premium for a defined worst case and lower margin requirements.

The bottom line

The iron condor is the premium seller's most complete range-income structure: neutral outlook, defined loss on both wings, and profit that simply requires the underlying to sit still long enough for theta to do its job. Place strikes at well-defined OI levels on NSE, collect the credit, and manage the position if either short strike comes under pressure. The four-leg structure is more complex than a naked strangle but the defined loss and margin efficiency make it the disciplined choice for traders who want sustainable, repeatable income from weekly NIFTY expiries.
