Options Structure / Strategy
Education only · our voice · free public data
Definition
A defined combination of option legs (and sometimes stock) chosen to express a view on direction, volatility, and/or time, with a known payoff profile. Examples: vertical spreads, iron condors, calendars, risk reversals, straddles/strangles.
How to read it
Every structure is a bundle of exposures: to price (delta), to volatility (vega), to time decay (theta), and to convexity (gamma). Choosing a structure is choosing WHICH of these you want to be long or short. A debit vertical is long direction with capped cost; an iron condor is short volatility and long time decay in a range; a calendar is long vega and long time-differential; a risk reversal is a leveraged directional bet financed by selling the other tail. The structure should match not just your direction but your view on IV and its skew, because you are trading the whole surface, not a single price.
How practitioners use it
Used as context among multiple indicators — never as a standalone signal to act.
Less common professional uses
Structure selection is really a choice on the IV SKEW: financed risk reversals exploit put skew (rich downside puts fund cheap upside calls), while call/put ratio spreads and broken-wing butterflies monetize specific curvature of the smile - selecting strikes without reading the skew leaves edge on the table. The Greeks of a structure are path- and time-dependent: an iron condor is short gamma, so its comfortable theta income reverses violently near expiry if price approaches a short strike (gamma risk dominates theta), making expiry-week management, not entry, the real risk driver. Vega term structure matters: calendars and diagonals are long the difference between near- and far-dated IV, so they profit from a steepening vol term structure independent of direction - a bet on the shape of the surface over time. Pin risk and early-assignment risk on American options (especially around ex-dividend and deep ITM short legs) can turn a 'defined-risk' structure into an overnight stock position - a discontinuity the payoff diagram hides.
