TradeApiService.CONTRACT = contract. 使用服务端方法 contract。这是 *ApiService 常量，不是客户端成员方法。

请求

TigerRequest<ContractResponse>

ModelValue: ContractModel.

参数

SDK property	C# type	API field	SDK default	Required	Constraints
`Lang`	Language	`lang`	None (omitted if not set)	no	—
`Account`	string (nullable)	`account`	null	Auto-filled if empty	TradeClient uses DefaultAccount when empty
`SecretKey`	string	`secret_key`	null	no	—
`SecType`	string	`sec_type`	TigerOpenAPI.Common.Enum.SecType.STK.ToString()	Optional	—
`Currency`	string	`currency`	null	Optional	—
`Right`	string	`right`	null	Optional	—

ContractResponse inherits TigerResponse; its data property is ContractItem. Key SDK fields: ContractId: Int32, Identifier: string, Symbol: string, SecType: string, Expiry: string, ContractMonth: string, Strike: Double, Right: string.

示例

TigerRequest<ContractResponse> request = new()
{
    ApiMethodName = TradeApiService.CONTRACT,
    ModelValue = new ContractModel { Account = tradeClient.GetDefaultAccount, SecType = "STK", Currency = "USD", Strike = 200.0, Symbol = "AAPL" }
};
ContractResponse? response = await tradeClient.ExecuteAsync(request);

响应类型

ContractItem? data = response?.Data; // response 或 data 缺失时为 null

返回示例

{
  "code": 0,
  "message": "success",
  "timestamp": 1785528000000,
  "data": [
    {
      "symbol": "AAPL",
      "secType": "STK",
      "exchange": "SMART",
      "market": "US",
      "lotSize": 1,
