Build multi-leg option strategies and see payoff at expiry, max P&L and breakevens.
Legs
This shows the payoff at expiry only — it is not live mark-to-market P&L and ignores time value, implied volatility and interest. You enter the premiums yourself, so nothing here reflects current market prices. Charges (brokerage, STT, GST) are not included. Educational tool only, not investment advice.
Frequently asked questions
Does this use live option prices?
No. You enter the premiums yourself, so it works any time and needs no market-data feed. It shows the payoff at expiry, not live mark-to-market P&L.
What is the break-even point?
The underlying price(s) at which the strategy's payoff at expiry is exactly zero — below/above which you start making or losing money.
Once a strategy is live, PnL Book journals every leg and shows your real, after-cost P&L as it plays out — no re-keying premiums into a calculator.
