What this long-options comparison models
A long straddle buys a call and put at one strike. This tool chooses the available shared strike nearest the fetched underlying quote. A long strangle uses a put strike below that quote and a call strike above it. Both legs have the same expiration and a 100-share multiplier.
Check the premiums before interpreting the result
The tool uses each contract’s daily-close field from a Massive snapshot. It does not use an executable bid or ask, and the underlying quote and option closes can have different observation times. A lower displayed debit is a comparison of those inputs, not proof that you can fill the trade at that cost.
Read the expiration formulas
Let D be the sum of the two per-share premiums. At expiration, per-share profit/loss is max(S − call strike, 0) + max(put strike − S, 0) − D. Maximum loss is D; a two-leg position costs 100 × D before fees. The upper breakeven is the call strike plus D. The lower is the put strike minus D, provided that price is nonnegative. Upside profit has no fixed cap; downside profit is bounded because the underlying cannot fall below zero.
Use a supported snapshot subset
Enter a supported US stock or ETF, load options and select an expiration. The request returns at most 250 rows within ±20% of the underlying quote, starting at expirations at least seven calendar days ahead. The page reports if more rows exist. Missing premiums, nonstandard contract multipliers or missing call/put pairs can prevent a comparison; this is not a full-chain availability guarantee.
Adjust the strangle and inspect the curves
Select an available OTM put and OTM call for the selected expiry. The result and piecewise-linear chart update from the loaded snapshot. Both curves use the same price axis and include strikes and breakevens. Reload to request another snapshot; changing strikes does not fetch live premiums.
Cost is not a forecast
An OTM strangle generally has a smaller debit than a comparable near-ATM straddle, but it also changes the payoff region. Calculate the actual breakevens instead of assuming one strategy is always superior. The sum of strangle premiums is not an expected-move estimate. No probability of profit is calculated here.
Before expiry, other variables matter
The diagram values intrinsic payoff only at expiration. Before expiry, time remaining, implied volatility, spreads and changes in the underlying affect option value. Leg Greeks are provider estimates and are not a forecast or a net-position risk report. A scheduled event can already be reflected in the premium; an event alone does not establish a profitable trade.
Exercise and platform boundaries
These calculations exclude fees and exercise-related costs. Review expiration and exercise instructions with your broker. Pineify’s source-writing tools do not make a multi-leg options backtest or broker execution connection available automatically in TradingView. This comparator is educational, not investment advice.
