Long Strangle Calculator
A long strangle is like a straddle but with OTM strikes: buy an OTM call and an OTM put. It's cheaper than a straddle but requires a bigger move to profit.

Practical example
When to use it
- You think RV > IV and expect a violent, directionally-ambiguous move
- You want more gamma-per-dollar than a straddle — OTM legs have lower premium so R:R is sharper for a large move
- You're playing a binary catalyst where the expected move is larger than the straddle implies
- You're willing to accept wider break-evens and lower probability of profit in exchange for cheaper entry
Risks
- Break-evens are wider than a straddle — you need a bigger move to profit
- Higher probability of both legs expiring worthless (the stock stays between the strikes)
- Double theta burn and IV crush risk are the same as a straddle, just on a cheaper structure
- OTM options have less absolute vega/gamma than ATM — the move must be substantial to convert the position into meaningful profit
The deeper breakdown
How a Long Strangle Works
Buy an OTM call and an OTM put with the same expiration. Same V-shaped vol bet as a straddle, but using cheaper OTM strikes. Total premium is lower, but break-evens are wider — the stock must move past the respective strikes, plus the debit paid.
Example
AAPL at $195. Buy the $200 call for $2.60 and the $190 put for $2.20. Total cost: $4.80 ($480).
Strangle vs Straddle
A strangle sacrifices the ATM "guaranteed some intrinsic value" zone in exchange for a much lower debit. The tradeoffs:
Put differently: straddles favor frequent moderate winners; strangles are a bigger swing for a better R:R when you hit.
Key Takeaway
Strangles are a cheaper vol bet for when you expect the move to be large. Choose strikes based on where the stock needs to go for the trade to make sense — typically the strikes of the implied move or just inside them. Same IV-crush and theta risks as a straddle apply.
