The strangle strategy: a cheaper bet on a big move
An out-of-the-money call and put. Lower cost than a straddle, with a wider gap to cross.
Updated 2026-10-07
What a strangle is
A long strangle buys an out-of-the-money call above the index and an out-of-the-money put below it, for the same expiry. Like the straddle, it does not pick a direction. Unlike the straddle, both legs start with no intrinsic value, so the position is cheaper to open and needs a bigger move before it pays.
Straddle or strangle
The choice is a trade between cost and distance. The straddle costs more and starts making money sooner; the strangle costs less and needs the index to travel past a strike before either leg has any intrinsic value. If the move never comes, the strangle loses less. If it comes and stops short, the strangle can expire worthless where a straddle would have recovered part of its cost.
What works against it
The same two forces as any long-premium position. Theta drains both legs daily, and out-of-the-money options are almost all time value, so the decay is a large share of what was paid. Vega cuts both ways: a rise in implied volatility helps even before the index moves, and a fall after an event can erase the position's value quickly.
The short strangle
Selling the two legs collects a smaller credit than a short straddle but leaves a wider band in which the seller keeps all of it. It is one of the most commonly sold positions on index options, and its loss side is still open-ended beyond either breakeven. The iron condor is the same idea with that open end capped.
A worked example
NIFTY at 24,000, one lot of 65 on each leg. Premiums are illustrative, chosen to be round, not quotes from any session.
- Buy the 24,200 call at 90
- Buy the 23,800 put at 85
- Net premium: a debit of 175 points, or 11,375 rupees per lot.
- Breakevens: 23,625 and 24,375 at expiry.
- Maximum profit: open-ended: it keeps growing the further the index moves past a breakeven.
- Maximum loss: 175 points, or 11,375 rupees per lot.
| NIFTY at expiry | Points | Rupees per lot |
|---|---|---|
| 23,400 | +225 | +14,625 |
| 23,625 | 0 | 0 |
| 23,800 | -175 | -11,375 |
| 24,000 | -175 | -11,375 |
| 24,200 | -175 | -11,375 |
| 24,375 | 0 | 0 |
| 24,600 | +225 | +14,625 |
Charges, taxes and slippage come off every line of that table. The strategy builder draws the same payoff as a curve with live premiums, so you can move a strike and watch every number above change.
Questions people ask
What is the difference between a straddle and a strangle?
A straddle buys a call and a put at the same strike, usually at the money. A strangle buys them at two different out-of-the-money strikes. The strangle is cheaper to open but needs a larger move before it profits.
How do you calculate strangle breakevens?
Add the total premium to the call strike for the upper breakeven, and subtract it from the put strike for the lower one. With a 24,200 call, a 23,800 put and 175 points paid in total, the breakevens at expiry are 24,375 and 23,625.
Is a short strangle safe?
It has a high chance of keeping some premium when markets are quiet, but its loss is open-ended if the index moves sharply past either breakeven, and it requires substantial margin. Many traders buy further out-of-the-money options to cap that risk, which turns it into an iron condor.
