Build any strategy up to four option legs plus a stock position — spreads, straddles, condors, covered calls — and see the profit-and-loss curve at expiration with breakevens, max profit, and max loss.

The visualizer models a structure — QuantLogix Pro shows where real money is positioning:
Per-leg P&L at expiration — A call is worth max(S − K, 0) and a put max(K − S, 0) at expiry. A bought leg earns intrinsic − premium; a sold leg earns premium − intrinsic. Each contract controls 100 shares, so leg P&L is multiplied by 100 × contracts. A stock position adds (S − basis) × shares.
Breakevens — The total payoff is piecewise linear with kinks only at strikes, so breakevens are found exactly where the P&L line crosses zero between sampled points (linear interpolation).
Max profit / max loss — Evaluated at S = 0 and at every strike. If the combined position keeps gaining as the stock rises without bound (net long calls / long stock), max profit is unlimited; if it keeps losing (net short calls / short stock), max loss is unlimited.
What this intentionally omits — Time value before expiration, implied volatility, early assignment, dividends, and margin. This is the expiration payoff — the skeleton of the trade, not its mark-to-market path.
Educational tool — not investment advice. Options involve substantial risk and are not suitable for every investor; selling options can expose you to unlimited losses. Figures assume expiration exercise/assignment with no fees, dividends, or early assignment. QuantLogix is a research platform, not a registered investment advisor.
