Use cases: adjusting a candidate iron condor's wing widths to compare risk-reward at different strike spacings, modeling a calendar spread's behavior at different DTE combinations, or stress-testing a complex position (jade lizard, ratio spread, broken wing butterfly) before placing it live. Every change updates the P&L curve and Greeks instantly.
Compare-mode lets you place two strategies side-by-side: same underlying, same expiration, different structures. The comparison highlights subtle trade-offs that aren't visible from looking at either structure alone — e.g., how much an iron butterfly's narrower profit zone costs you in capital efficiency vs an iron condor at the same expiration.
