Defined vs Undefined Risk
A defined-risk structure has a known maximum loss capped by a long option wing. Iron condors, credit spreads, and debit spreads are all defined-risk. An undefined-risk structure (naked options, short strangles) has theoretically unlimited loss on the call side. ACondor enforces defined-risk-only in IRA and cash accounts automatically. In margin accounts, undefined-risk is off by default for all engines and must be explicitly enabled per-symbol.
