What is the difference between a Debit and Credit spread?

A Debit spread means you pay more premium than you collect (Net Debit), so cash leaves your account to open the trade. A Credit spread means you collect more premium than you pay (Net Credit), so cash enters your account upfront.

Why does the graph show 'Unlimited' Max Loss?

If you sell an uncovered Call (naked short), the underlying stock theoretically has no limit to how high it can rise. Therefore, your maximum loss is mathematically unlimited. The calculator flags this extreme risk.

Does this simulator account for Option Greeks?

This is a Payoff Calculator mapping Profit/Loss at Expiration. Therefore, time decay (Theta) and implied volatility (Vega) have already resolved to zero. The intrinsic value is purely delta-driven based on the strike price vs the spot price.

What is an 'Unlimited' Max Profit scenario?

An 'Unlimited' Max Profit scenario occurs when you buy a Call (anticipating a price surge) or have a strategy with uncapped upside. Since there's theoretically no limit to how high a stock can go, your profit potential is uncapped. This builder will indicate 'Unlimited' in such cases to highlight the high-reward nature of the trade.

Options Strategy Builder India — Payoff Graph & Greeks Si...

The Options Strategy Builder is the ultimate tool for F&O traders in India to visualize risk and reward before entering complex trades in Nifty, Bank Nifty, or stocks. Entering a multi-leg strategy without understanding your exact mathematical breakeven or maximum downside is high-risk.

This simulator allows you to combine multiple Calls (CE) and Puts (PE) across different strikes to project your exact Net Profit & Loss (PnL) at expiration.

How the Payoff Calculator Works?

The calculator uses standard European options pricing logic at expiration to generate a PnL point for every possible underlying asset price. It calculates the intrinsic value of each leg and subtracts/adds the premium paid/received to arrive at your net result.

Max Profit: The absolute highest return the strategy can yield at expiration. In debit spreads, this is typically capped.
Max Loss: The absolute worst-case scenario. In naked selling (short calls/puts), this can technically be unlimited.
Breakeven: The exact price(s) the underlying asset must cross for the strategy to turn from an unrealized loss into an unrealized profit.
Net Premium: The total cash outflow (Debit) required to enter the trade, or cash inflow (Credit) received upfront.

Strategy Example: The Iron Condor

An Iron Condor is a non-directional strategy used when you expect low volatility. It involves 4 legs:

1. Sell 1 OTM Put
2. Buy 1 further OTM Put (Protection)
3. Sell 1 OTM Call
4. Buy 1 further OTM Call (Protection)

Result: You collect a net credit upfront. The simulator will instantly show a flat plateau of Max Profit in the middle (if the price stays between the short strikes) and capped Max Loss on the extreme left and right 'wings'.
