术语表
墙位、GEX、DEX、期权流及相关成交术语的简短定义。
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.打开定义Put 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.打开定义Gamma 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.打开定义Gamma 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.打开定义Option flowOption flow is the time-and-sales stream of options prints: contract, size, premium, and inferred aggressor side.打开定义Unusual 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.打开定义Delta exposure (DEX)DEX estimates share-equivalent directional weight of an options trade, roughly delta × size (with the usual multiplier).打开定义Delta 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.打开定义Open 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.打开定义Volume / 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.打开定义Options sweepA sweep is a large order filled across multiple exchanges in rapid succession, usually to grab available liquidity quickly.打开定义Options block tradeAn options block is a large single print, or same-second aggregate, sized well above typical retail clips.打开定义Smart money flowIn scanners, “smart money” usually means large or institutional-style prints. It is a size heuristic, not account identity.打开定义Max painMax pain is the underlying price that theoretically minimizes total option-holder payoff at expiration.打开定义Dealer hedgingDealer hedging is market makers buying or selling the underlying to stay near delta-neutral as price and gamma change.打开定义IV RankIV Rank places today’s implied volatility between its recent high and low so “expensive” or “cheap” is relative to that underlying’s history.打开定义0DTE (zero days to expiration)0DTE options expire the same trading day. Gamma and theta move fastest near the money on that clock.打开定义IV 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.打开定义Put/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.打开定义Moneyness (ITM / ATM / OTM)Moneyness labels a contract relative to spot: in-the-money (ITM), at-the-money (ATM), or out-of-the-money (OTM).打开定义Aggressor 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.打开定义Pin riskPin risk is expiration uncertainty when spot sits near a strike with large open interest: assignment and last-minute hedging get noisy.打开定义
