Data availability note

数据可用性说明

Longbridge CLI may not expose a dedicated northbound-fund endpoint. Always run 
longbridge capital --help
and 
longbridge broker-holding --help
first to discover available flags. If a dedicated northbound command is absent:
  1. Use 
    longbridge capital <SYMBOL> --flow --format json
    for proxy signals (large-order / institutional net flow as a northbound proxy).
  2. Use 
    longbridge ah-premium
    commands for AH arbitrage context.
  3. Inform the user that official daily northbound totals are published by Hong Kong Exchanges (hkex.com.hk) and the Shanghai/Shenzhen Stock Exchanges.
Longbridge CLI可能未提供专门的北向资金端点。请先运行
longbridge capital --help
和
longbridge broker-holding --help
以查看可用参数。若没有专门的北向资金命令：
  1. 使用
    longbridge capital <SYMBOL> --flow --format json
    获取代理信号（以大额订单/机构净流量作为北向资金代理指标）。
  2. 使用
    longbridge ah-premium
    命令获取AH套利相关信息。
  3. 告知用户官方每日北向资金总额由香港交易所（hkex.com.hk）及沪深交易所发布。

Workflow

工作流程

  1. Check available commands:
    bash
    longbridge capital --help
longbridge broker-holding --help
  2. If a 
    northbound
    or 
    stock-connect
    subcommand exists    , call it directly:
    bash
    longbridge northbound --format json
longbridge northbound --sector --format json
  3. Otherwise, build a proxy analysis: a. For key dual-listed A+H stocks (e.g. 
    601398.SH
    /
    939.HK
    , 
    600519.SH
    , 
    300750.SZ
    ), fetch capital flow:
    bash
    longbridge capital <SYMBOL> --flow --format json
    b. Fetch AH premium for cross-market arbitrage signals:
    bash
    longbridge calc-index <SYMBOL> --format json
longbridge ah-premium <SYMBOL> --format json
    Run 
    longbridge ah-premium --help
    to verify exact flags. c. Fetch today's quote for southbound-relevant HK stocks:
    bash
    longbridge quote <SYMBOL> --format json
  4. Aggregate and interpret:
    • Net inflow direction and magnitude per sector.
    • Consecutive net-buy / net-sell days.
    • Correlation with AH premium compression (northbound buying narrows premium).
  5. Output the flow summary (see Output section). Cite Longbridge Securities and note if official HKEX data is needed for exact totals.
  1. 检查可用命令:
    bash
    longbridge capital --help
longbridge broker-holding --help
  2. 若存在
    northbound
    或
    stock-connect
    子命令    ，直接调用：
    bash
    longbridge northbound --format json
longbridge northbound --sector --format json
  3. 否则，构建代理分析: a. 针对关键A+H两地上市股票（如
    601398.SH
    /
    939.HK
    、
    600519.SH
    、
    300750.SZ
    ），获取资金流数据：
    bash
    longbridge capital <SYMBOL> --flow --format json
    b. 获取AH溢价数据以捕捉跨市场套利信号：
    bash
    longbridge calc-index <SYMBOL> --format json
longbridge ah-premium <SYMBOL> --format json
    运行
    longbridge ah-premium --help
    确认具体参数。 c. 获取南向相关港股的当日报价：
    bash
    longbridge quote <SYMBOL> --format json
  4. 汇总与解读:
    • 各行业的净流入方向及规模。
    • 连续净买入/净卖出天数。
    • 与AH溢价收窄的相关性（北向资金买入会缩小溢价）。
  5. 输出资金流汇总报告（见输出示例）。注明数据来源为Longbridge Securities，并提示如需精确总额可参考港交所官方数据。
