K 線
該接口用於獲取標的的 K 線數據。
行情權限要求免費
- 按帳戶等級配額,每自然月可查詢 100–3,000 個標的(每月重置,詳見文檔中的配額表)。
- 美股:預設免費贈送 US LV1 行情(含盤前、盤中、盤後、夜盤全時段)。
- 港股:預設贈送 LV1 行情。
- 美股期權:預設無權限,需購買「OPRA 美股期權行情 (OpenAPI)」行情卡。
Info
注意:本介面只能獲取到最近 1000 根 K 線,如需獲取較長的歷史數據,請訪問介面:獲取標的歷史 K 線。
# Tesla 日 K 線(最近 100 根)
longbridge kline TSLA.US
# Apple 週 K 線
longbridge kline AAPL.US --period week
# NVDA 最近 20 根日 K
longbridge kline NVDA.US --period day --count 20

Request
Parameters
| Name | Type | Required | Description |
|---|---|---|---|
| symbol | string | 是 | 標的代碼,使用 ticker.region 格式,例如:700.HK |
| period | int32 | 是 | k 線週期,例如:1000,详见 Period |
| count | int32 | 是 | 數據數量,例如:100校验规则: 請求數量最大為 1000 |
| adjust_type | int32 | 是 | 復權類型,例如:0,详见 AdjustType |
| trade_session | int32 | 否 | 交易時段,0: 盤中,100: 所有延長時段(盤前,盤中,盤後,夜盤) 注意:夜盤數據已包含在 US LV1 中免費提供,僅支援美股;開啟 enable_overnight 參數即可獲取 |
