Straddle & Strangle: Trading Big Moves Without Predicting Direction
Updated August 2026 · By PaperBull Editorial Team
Quick answer: A Straddle buys both an ATM Call and ATM Put; a Strangle buys OTM versions of each. Both profit from a big move in either direction — the risk isn't picking the wrong side, it's the market not moving enough, or IV crush eating your premium even if it does.

Every options trader has been here: you're certain something big is about to happen — an RBI rate decision tomorrow, quarterly results tonight, election counting next week — but you have no idea which way the market goes. A Straddle or Strangle lets you profit from the move itself, without needing to guess the direction.
These are volatility strategies. You're not betting up or down — you're betting on movement.
Long Straddle — Buy Both ATM Call and ATM Put
A Long Straddle means buying an ATM Call and an ATM Put on the same underlying, same strike, same expiry. If the market makes a big move in either direction, one option gains more than the total premium you paid, and you profit.
Example: NIFTY Straddle before RBI Policy
- NIFTY at 25,000, RBI policy announcement tomorrow
- Buy 25,000 CE at ₹180
- Buy 25,000 PE at ₹165
- Total premium paid: ₹345 per share
- Total cost for 1 lot (65 shares): ₹22,425
- Breakeven: NIFTY above 25,345 or below 24,655
If RBI surprises the market with a rate cut and NIFTY jumps 400 points to 25,400, your CE explodes in value while the PE expires worthless. The CE might be worth ₹500+ — a profit of (500 − 345) × 65 = ₹10,075. If instead NIFTY drops sharply on a hawkish statement, the PE gains similarly.
Long Strangle — Cheaper But Needs a Bigger Move
A Strangle is similar to a Straddle, but instead of ATM strikes you use OTM strikes — a slightly higher-strike Call and a slightly lower-strike Put. Cheaper premium, but it needs a larger move to turn profitable.
Example: NIFTY Strangle before Budget
- NIFTY at 25,000, Budget presentation next day
- Buy 25,200 CE at ₹90
- Buy 24,800 PE at ₹85
- Total premium: ₹175 per share (vs ₹345 for the straddle)
- Total cost for 1 lot: ₹11,375
- Breakeven: NIFTY above 25,375 or below 24,625
Straddle vs Strangle — How to Choose
| Long Straddle | Long Strangle | |
|---|---|---|
| Cost | Higher premium | Lower premium |
| Move needed to profit | Moderate (around 1-2%) | Larger (around 2-3%) |
| Best when | ATM IV is reasonable | ATM IV is very expensive |
| Risk | Lose entire premium if market stays flat | Lose entire premium if market stays flat |
| Ideal event | Quick binary events (RBI, GDP) | Slower building moves (elections) |
The Biggest Enemy: IV Crush
Here's the part nobody mentions when they first explain straddles: IV Crush can kill your profits even when the market moves.
Before a major event, Implied Volatility inflates because everyone is buying protection. Options get expensive. The moment the event passes — regardless of the outcome — IV usually collapses back to normal. That crush drags option premiums down with it.
So you might buy a straddle for ₹345, NIFTY might move 300 points (which feels like a lot), but because IV crashed 30%, your straddle might only be worth ₹280. You were right on the move and still lost money. See our IV & India VIX guide for the full mechanics.
Best Events for Straddle/Strangle in Indian Markets
- RBI Monetary Policy (every 6-8 weeks): markets can swing 300-600 points depending on rate decisions and Governor commentary.
- Union Budget (February 1 each year): historically one of the biggest single-day market moves.
- US Fed FOMC meetings: global risk sentiment can shift dramatically overnight.
- Major quarterly results (Reliance, TCS, HDFC Bank): individual stocks, but moves often ripple into index options.
- General elections: the 2024 elections saw NIFTY move over 2,000 points intraday — a straddle bought a couple of weeks earlier paid off massively.
When Straddles Fail
These strategies fail when the market does exactly what it often does — nothing. If NIFTY closes flat after an RBI policy, or makes a smaller-than-expected move, Theta decay eats the position and IV crush accelerates the loss. Both options lose value and you're left with nothing.
That's why risk management matters: never put more than 3-5% of your trading capital into a single event straddle. Plenty of traders have blown up accounts by oversizing event trades that didn't pay off — see risk management for options traders before your next one.

What's the difference between a Straddle and a Strangle?
A Straddle buys the same ATM strike for both the Call and Put. A Strangle buys an OTM Call and an OTM Put instead, which costs less premium but needs a bigger move to become profitable.
What is IV crush and why does it matter for straddles?
Before a big event, Implied Volatility rises and inflates premiums. Right after the event, IV often collapses fast regardless of outcome — so even if the market moves the way you expected, the premium can shrink because IV crushed. It's the single most common way straddle buyers lose on a 'correct' call.
How do I avoid IV crush when buying a straddle?
Enter a few days before IV peaks, not the day before the event when it's already at its most expensive. Buying too close to the event means you're paying the top price for volatility that's about to deflate.
What happens if the market doesn't move after I buy a straddle?
You lose, slowly. Both options bleed Theta every day, and if the event passes with a smaller-than-expected move, IV crush accelerates the loss. This is the most common failure mode for straddles — the market doing nothing.
How much capital should I risk on an event straddle?
A common rule is no more than 3-5% of trading capital on a single event trade. Straddles can lose their entire premium, so oversizing one event bet is a fast way to damage an account.
Can I practise straddles before a real event?
Yes — PaperBull lets you set up a straddle ahead of the next RBI policy or results announcement and watch how IV crush and the actual move affect your P&L, with zero real money at risk.
