该对象构成买方与卖方之间达成的具体交易（deal）。它出现在 Pmp 集合中，即表示该展示可按该交易的条款获取。更多细节参见第 7.3 节。译稿校对中ENThis object constitutes a specific deal that was struck between a buyer and a seller. Its presence with the Pmp collection indicates that this impression is available under the terms of that deal. Refer to Section 7.3 for more details.
| Attribute | Type | Description |
|---|---|---|
| id required | string | 直接交易（direct deal）的唯一标识符。译稿校对中ENA unique identifier for the direct deal. |
| bidfloor default 0 | float | 该展示的最低出价，以 CPM（Cost Per Mille，每千次展示成本）计价。译稿校对中ENMinimum bid for this impression expressed in CPM. |
| bidfloorcur default "USD" | string | 指定币种，采用 ISO-4217 alpha 代码。若交易平台允许，它可以不同于竞价方返回的出价币种。本字段不继承自 Imp.bidfloorcur，要么显式指定，要么默认为 USD。译稿校对中ENCurrency specified using ISO-4217 alpha codes. This may be different from bid currency returned by bidder if this is allowed by the exchange. This field does not inherit from Imp.bidfloorcur; it is either explicitly specified or defaults to USD. |
| at | integer | 可选，用于覆盖竞价请求整体的拍卖类型：1 = 第一价格拍卖（First Price），2 = 第二价格加价拍卖（Second Price Plus），3 = bidfloor 传递的取值即双方约定的成交价。交易平台可定义额外的拍卖类型。译稿校对中ENOptional override of the overall auction type of the bid request, where 1 = First Price, 2 = Second Price Plus, 3 = the value passed in bidfloor is the agreed upon deal price. Additional auction types can be defined by the exchange. |
| wseat | string[] | 允许参与该交易竞价的买方席位（buyer seats，如广告主、代理商）白名单。席位 ID 与其所指代的买方客户之间的映射，必须由竞价方与交易平台事先（a priori）协调一致。省略则表示无席位限制。译稿校对中ENAllowed list of buyer seats (e.g., advertisers, agencies) allowed to bid on this deal. IDs of seats and the buyer’s customers to which they refer must be coordinated between bidders and the exchange a priori. Omission implies no seat restrictions. |
| wadomain | string[] | 允许参与该交易竞价的广告主域名（如 advertiser.com）数组。省略则表示无广告主限制。译稿校对中ENArray of advertiser domains (e.g., advertiser.com) allowed to bid on this deal. Omission implies no advertiser restrictions. |
| guar default 0 | integer | 指示该交易为保量（guaranteed）类型且竞价方必须对该交易出价：0 = 非保量交易，1 = 保量交易。译稿校对中ENIndicates that the deal is of type guaranteed and the bidder must bid on the deal, where 0 = not a guaranteed deal, 1 = guaranteed deal. |
| mincpmpersec | float | 每秒最低 CPM。这是视频或音频展示机会的价格底线，相对于广告主可提交出价的时长而言。译稿校对中ENMinimum CPM per second. This is a price floor for video or audio impression opportunities, relative to the duration of bids an advertiser may submit. |
| durfloors | object[] | 按时长划分的底价信息容器，在给定交易适用于视频或音频需求时使用。DurFloors 对象数组（参见第 3.2.35 节）。译稿校对中ENContainer for floor price by duration information, to be used if a given deal is eligible for video or audio demand. An array of DurFloors objects (see Section 3.2.35). |
| ext | object | 供交易平台（exchange）对 OpenRTB 进行专属扩展（exchange-specific extensions）的占位对象。译稿校对中ENPlaceholder for exchange-specific extensions to OpenRTB. |
译注
译者注Deal：Pmp 的子对象，表示买卖双方事先达成的具体交易；业内文档一般保留英文对象名 Deal。2.6 相比 2.5 新增 guar（保量标志）、mincpmpersec 与 durfloors（按时长底价），程序化保量与音视频时长定价首次获得规范级表达。译稿校对中
guar 的实践含义：guar = 1 即程序化保量（programmatic guaranteed），竞价方必须出价（通常附带保量投放义务与固定价格）；买方系统应对保量交易单独配额与监控，避免欠交（underdelivery）违约。译稿校对中
bidfloorcur 不继承 Imp 级币种：这是 2.6 明确的结算口径——Deal 级底价币种要么显式指定，要么默认 USD，不会隐式沿用 Imp.bidfloorcur；跨币种交易时应逐交易核对，避免结算争议。译稿校对中
mincpmpersec / durfloors 的适用：两者服务于音视频按时长定价的场景（如 CTV）；mincpmpersec 是全局每秒底价，durfloors 则按时长区间细化底价，后者存在时应优先适用。译稿校对中
