Long Straddle Strategy: Compare Straddles and Strangles
A long straddle buys a call and put at one strike and expiry. A strangle separates the strikes. Buying either structure limits loss to the debit plus fees; selling either creates unbounded upside loss. Compare all four using the same prices, size and expiry assumptions below.
Compare four structures on one sample
Start with the editable example or load a chain snapshot. Each structure uses the same spot, expiry horizon, matched quantity, multiplier and fees. Long and short use the same premiums to isolate position direction; real buy and sell fills differ.
Illustrative manual sample: one underlying, one expiry 30 calendar days away. No market quote.
Snapshot responses may be cached for one hour and stock quotes for 30 seconds. Import considers only the first 250 rows; malformed or nonstandard-multiplier records are excluded. Retrieval time does not establish quote freshness.
Total fees include your entry and exit/settlement assumptions: 2 legs × contracts × fee. The multiplier scales a simple cash payoff; adjusted contracts with mixed deliverables are unsupported.
A straddle requires equal strikes, not necessarily an at-the-money strike. A conventional out-of-the-money strangle places the put below spot and the call above it; this calculator also accepts ordered strikes that are already in the money.
One scenario for every structure
Expiration risk and model sensitivity
Dollar results are for the whole two-leg position, after modeled fees. Vega is $ per +1 IV percentage point; theta is $ per calendar day, evaluated at the starting inputs. Missing IV suppresses model values, not expiration payoffs.
| Strategy | Strike width | Gross debit / credit | Max loss | Best expiry P&L | Expiry breakevens | Vega | Theta | Scenario model P&L |
|---|---|---|---|---|---|---|---|---|
| Long straddle | $0.00 | $800.00 debit Fees: $2.00 | $802.00 | Unbounded | $91.98 / $108.02 | $22.85 | $-13.33 | $257.28 |
| Short straddle | $0.00 | $800.00 credit Fees: $2.00 | Unbounded | $798.00 | $92.02 / $107.98 | $-22.85 | $13.33 | $-261.28 |
| Long strangle | $10.00 | $400.00 debit Fees: $2.00 | $402.00 | Unbounded | $90.98 / $109.02 | $20.17 | $-11.77 | $217.62 |
| Short strangle | $10.00 | $400.00 credit Fees: $2.00 | Unbounded | $398.00 | $91.02 / $108.98 | $-20.17 | $11.77 | $-221.62 |
Short call risk is unbounded as the stock rises; received premium is not capital protection. At a zero stock price, long/short straddle P&L is $9198.00 / $-9202.00, and long/short strangle P&L is $9098.00 / $-9102.00. A negative mathematical lower breakeven is omitted because stock prices cannot fall below zero.
Pre-expiry values use European Black-Scholes with constant rates and continuous dividend yield, a flat IV shift across legs and 365-day years. They subtract your entered entry premiums, which can differ from model values even at zero elapsed days. American early exercise, skew changes, borrow costs, spread, margin, liquidity and assignment are not modeled. IV outside 0-500% makes the scenario unavailable; no clipping is used. At expiry, intrinsic value replaces the model.
Expiration payoff comparison
A finite chart window does not cap the short call loss. The table below gives exact values at common prices.
| Stock at expiry | Long straddle | Short straddle | Long strangle | Short strangle |
|---|---|---|---|---|
| $80.00 | $1198.00 | $-1202.00 | $1098.00 | $-1102.00 |
| $90.00 | $198.00 | $-202.00 | $98.00 | $-102.00 |
| $100.00 | $-802.00 | $798.00 | $-402.00 | $398.00 |
| $110.00 | $198.00 | $-202.00 | $98.00 | $-102.00 |
| $120.00 | $1198.00 | $-1202.00 | $1098.00 | $-1102.00 |

Strike width changes the price hurdle
A straddle uses one strike for both legs. A conventional strangle uses an out-of-the-money put below spot and an out-of-the-money call above spot. For the same expiry, moving the strikes outward usually lowers both option premiums, but it also creates a wider interval with no intrinsic value. Lower debit alone does not establish which position is preferable. Compare the resulting breakevens and the move you are actually testing.
Both positions are exposed to volatility, with no guarantee of being delta-neutral. Long positions have positive vega; a fall in IV can offset gains from a stock move before expiry. Short positions reverse that exposure. Time decay generally hurts buyers and helps sellers, but theta depends on moneyness, rates and dividends. The calculator derives local sensitivities from the stated model instead of assuming a fixed theta sign.
See the OIC explanations of long straddles and long strangles for their expiry payoff and volatility exposure.
A $100 sample: cheaper premium, wider breakevens
The editable sample uses spot $100, 30 days to one expiry, one contract per leg and a 100-share multiplier. The straddle buys the $100 call for $4 and $100 put for $4. The strangle buys the $105 call for $2 and $95 put for $2. Total modeled fees are $1 per contract, or $2 for each two-leg position. These are illustrative inputs, not market observations.
| Structure | Width | Max loss / best profit | Expiry breakevens | P&L at $110 |
|---|---|---|---|---|
| Long straddle | $0 | $802 max loss | $91.98 / $108.02 | +$198 |
| Short straddle | $0 | $798 best profit; unbounded loss | $92.02 / $107.98 | −$202 |
| Long strangle | $10 | $402 max loss | $90.98 / $109.02 | +$98 |
| Short strangle | $10 | $398 best profit; unbounded loss | $91.02 / $108.98 | −$102 |
For the long straddle at $110, the call pays $10 per share and the put expires worthless: ($10 − $4 − $4) × 100 − $2 = $198. The short position is not exactly the negative of this result because it also pays fees. At $100, both long positions lose their entire debit plus fees. At a zero stock price, the long straddle earns $9,198 and the short straddle loses $9,202; downside is bounded by zero, while upside call exposure has no finite ceiling.
The formula uses each leg, size and fees
Let C and P be entry premiums per share, Kc and Kp the call and put strikes, S the stock price at expiry, Q equal contracts per leg, M the contract multiplier, and F the total fee budget per contract. Set I = max(S − Kc, 0) + max(Kp − S, 0). Long P&L = (I − C − P) × Q × M − 2QF. Short P&L = (C + P − I) × Q × M − 2QF.
Long breakevens are Kp − (C + P + 2F/M) and Kc + (C + P + 2F/M). Short breakevens use net credit C + P − 2F/M instead. If net credit is negative, the short position has no profitable expiry price; if it is zero, every price between ordered strikes breaks even. A calculated lower boundary below zero is unreachable for a stock. Fees here are an explicit total budget, not a broker commission schedule.
The OIC documents the loss and assignment risks of short straddles and short strangles. Margin is collateral, not maximum loss; a broker can require more collateral or liquidate a position before expiry.
Before expiry, price, IV and time act together
Set scenario stock price to $100, elapsed days to 10, and IV shift to −5 percentage points to isolate an unchanged stock after time passes and IV falls from the sample's 35% to 30%. Then repeat with +5 points. Both long structures gain theoretical value from a positive IV shift, holding the other inputs fixed; both short structures lose it. A large stock move can dominate this sensitivity, so a short trade can still lose after an IV crush.
Vega and theta are local model derivatives, not a linear forecast for a large event. The scenario table reprices each leg at the remaining time and changed IV. The displayed Greeks use the starting inputs and stay fixed as the scenario changes. They are unavailable when the starting horizon is zero; scenario P&L at expiration uses only intrinsic value. The OIC model guide explains why formulas do not determine the premiums available in the market and why American exercise needs separate treatment.
Carry the same assumptions into TradingView Options
In TradingView's options strategy builder, choose the underlying and expiration, then add the call and put using the buy or sell controls. Verify the leg quantities and strikes before comparing its payoff view. TradingView's width setting controls the distance between strikes for supported multi-leg structures. Match the model horizon and volatility assumptions when comparing outputs.
Pineify's AI Stocks & Options Picker has an options-chain view with strike, expiration, bid/ask, IV and Greeks. Use available fields to inspect candidate legs; a field's presence is not proof of a fresh or fillable price. This page imports the daily close from Massive's option-chain snapshot, and displays the four daily timestamps. It does not request full history or guarantee a complete chain; a response can contain only the first 250 contracts.
Record actual fills, fees, quantity and trade notes in the Trading Journal. Keep modeled entry assumptions separate from executed trades, and record the source time for each leg. Neither this comparison nor a payoff diagram is a historical options backtest. For other structures, return to the TradingView strategies category or use the Options Strategy Builder.

Straddle and strangle questions
Does a long straddle profit from any stock-price move?
No. At expiration, the intrinsic value must exceed both entry premiums and fees. With a $100 shared strike, $8 combined premium, one 100-share pair and $2 total fees, the expiry breakevens are $91.98 and $108.02. Before expiry, time value and implied volatility also affect the exit price.
Is a short strangle safer because it collects a premium?
Premium received limits the best possible gross gain; it does not cap loss. The uncovered call can lose without bound as the stock rises, and the put can produce a large loss as it falls toward zero. Margin requirements, early assignment and forced liquidation are separate from the expiry payoff shown here.
Why compare equal quantities and one expiration?
Matched call and put quantities on the same underlying and expiration isolate strike width and position direction. Unequal quantities create a ratio position; different expirations create calendar exposure. Neither is represented by this calculator. Check each leg contract specification and deliverable before comparing real trades.
Can the scenario table be used as an options backtest?
No. It reprices a hypothetical position with a European Black-Scholes model using your stock price, time and IV scenario. It contains no historical trade sequence, executable bid/ask simulation, margin model or early-exercise model. Model P&L can differ from broker marks and actual fills.
What happens when snapshot fields are missing or stale?
Import requires all four matching contracts, daily closes, standard 100-share multipliers and daily timestamps no more than seven days old. This seven-day cutoff is a data-rejection rule, not a freshness guarantee. Missing IV leaves model estimates unavailable while expiry payoffs remain usable. Changing ticker or snapshot selections hides the old result until a new import or manual edit.
Is total straddle premium the same as a one-standard-deviation move?
No. Total premium is the entry cost used in the expiry breakeven equation. A probability range requires a separate distribution and time model. This calculator does not turn straddle or strangle premiums into an observed probability of profit.
