Glossary
Short definitions for walls, GEX, DEX, option flow, and related tape terms.
Call wallA call wall is the strike above spot with the densest call open interest or call-side gamma. Traders often treat it as resistance when dealers hedge.Open definitionPut wallA put wall is the strike below spot with the densest put open interest or put-side gamma. Traders often treat it as support when dealers hedge.Open definitionGamma exposure (GEX)GEX estimates aggregate dealer gamma from listed options. Positive gamma tends to dampen moves; negative gamma tends to amplify them. Option gamma is the building block; extreme short-gamma feedback is covered under gamma squeeze.Open definitionGamma squeezeA gamma squeeze is a feedback loop: aggressive call buying can leave dealers short gamma so they buy the underlying as price rises, which can accelerate the move—not a guaranteed outcome and not the same as a short-stock squeeze.Open definitionOption flowOption flow is the time-and-sales stream of options prints: contract, size, premium, and inferred aggressor side.Open definitionUnusual options activity (UOA)UOA flags contracts or underlyings trading far above recent norms in volume, size, or premium. It is an attention screen, not a directional signal.Open definitionDelta exposure (DEX)DEX estimates share-equivalent directional weight of an options trade, roughly delta × size (with the usual multiplier).Open definitionDelta impact (DEI)DEI scales delta exposure by typical stock volume so the same DEX reads louder in a quiet name than in a hyper-liquid one.Open definitionOpen interest (OI)Open interest is how many options contracts remain open. Unlike volume, it does not reset each morning and usually updates after the session.Open definitionVolume / open interest (Vol/OI)Vol/OI is today’s volume divided by open interest. High ratios mean today’s trading is large versus the standing book.Open definitionOptions sweepA sweep is a large order filled across multiple exchanges in rapid succession, usually to grab available liquidity quickly.Open definitionOptions block tradeAn options block is a large single print, or same-second aggregate, sized well above typical retail clips.Open definitionSmart money flowIn scanners, “smart money” usually means large or institutional-style prints. It is a size heuristic, not account identity.Open definitionMax painMax pain is the underlying price that theoretically minimizes total option-holder payoff at expiration.Open definitionDealer hedgingDealer hedging is market makers buying or selling the underlying to stay near delta-neutral as price and gamma change.Open definitionIV RankIV Rank places today’s implied volatility between its recent high and low so “expensive” or “cheap” is relative to that underlying’s history.Open definition0DTE (zero days to expiration)0DTE options expire the same trading day. Gamma and theta move fastest near the money on that clock.Open definitionIV crushIV crush is a sharp drop in implied volatility after uncertainty resolves, often after earnings. Premium can fall even when the stock moves your way.Open definitionPut/call ratioPut/call ratio compares put activity to call activity by contracts, volume, or premium. Context decides whether heavy puts mean hedges or bearish bets.Open definitionMoneyness (ITM / ATM / OTM)Moneyness labels a contract relative to spot: in-the-money (ITM), at-the-money (ATM), or out-of-the-money (OTM).Open definitionAggressor side (bid / ask)Aggressor side estimates who crossed the spread: prints at or above the ask often look like aggressive buying; at or below the bid, aggressive selling. Mid is ambiguous.Open definitionPin riskPin risk is expiration uncertainty when spot sits near a strike with large open interest: assignment and last-minute hedging get noisy.Open definition
