How the Calculation Works

Step 1: Input Valuation

Read parameters and compute total exposure: multiply order quantity by contract unit multiplier.

Step 2: Payoff & Boundary Evaluation

Evaluate terminal return at the selected target price using strict financial mathematical boundary logic.

Step 3: Frictional & Premium Netting

Deduct upfront capital commitments, taxes, or net debits to produce final net profit or loss realization.

Calculation Formula

Lower BE = Strike - Combined Premium | Upper BE = Strike + Combined Premium

Example Calculation

Buy 24,500 Call at ₹180 and 24,500 Put at ₹170 with 50 units.

Outcome: Lower BE: ₹24,150.00 | Upper BE: ₹24,850.00 | Max Loss: -₹17,500.00

Combined cost is ₹350 per unit. The trade generates net profit if the underlying finishes either below 24,150 or above 24,850 at expiration.

Assumptions & Parameters

  • Both call and put legs are opened at the exact same strike price and expiration date.

Frequently Asked Questions

What is a long straddle?

A long straddle is a market-neutral, high-volatility strategy created by purchasing an equal number of calls and puts at the exact same strike and expiration.

What is the maximum risk on a long straddle?

The maximum loss is 100% of the combined premium paid for both legs. It occurs if the price closes exactly at the strike on expiry.

How are the dual breakeven points calculated?

Lower Breakeven = Strike Price - Total Premium; Upper Breakeven = Strike Price + Total Premium.

When should a trader execute a long straddle?

When expecting explosive market volatility before a major event (earnings, budget, elections) regardless of direction.

What is the biggest risk with a straddle?

Theta (time decay) and volatility crush. If the price moves sideways, both legs decay rapidly towards zero.

Can a long straddle have unlimited profit?

Yes, on the upside there is no ceiling, while on the downside profit is capped only if the asset drops to zero.
