longbridge-flows

Single-symbol ownership and money-flow lens: who's buying/selling at the institutional, fund, insider, broker, and short-seller layers.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

When to use

• "13F 谁持仓最多", "Berkshire 13F", "巴菲特最新持仓", "active fund AUM ranking" → investors
• "哪些基金持有 NVDA", "AAPL 被多少 ETF 持有" → fund-holder
• "TSLA 高管最近买入", "AAPL Form 4", "内部人减持" → insider-trades (US only)
• "AMD 空头数据", "TSLA 做空比例", "days to cover" → short-positions (US only)
• "700.HK 中央结算", "腾讯经纪商持仓", "broker holding 700" → broker-holding (HK only)
• "X 资金面全景" → call multiple subcommands by market (US: fund-holder + insider-trades + short-positions; HK: fund-holder + broker-holding).

For intraday large/medium/small-order capital flow → longbridge-capital-flow. For institutional shareholders by % held → longbridge-corporate (shareholder).

Subcommands

Run longbridge <subcommand> --help if unsure of current flags. The CLI's built-in help is the canonical source.

Single symbol per call (except investors rankings).

Workflow

1. Resolve to <CODE>.<MARKET>. Reject US-only subcommands for non-US, HK-only for non-HK — explain politely.
2. Pick subcommands by prompt cue. Don't run all of them by default.
3. Call concurrently when the question is "全景资金面" style.
4. Summarise direction (net buying / net selling), top names, freshness (report date).
5. Cite Longbridge Securities (and SEC EDGAR for insider-trades / investors).

CLI

# Discover available subcommands and their flags first
longbridge --help
longbridge <subcommand> --help   # run for each subcommand before use

longbridge <investors-subcommand> --format json                   # AUM rankings (no CIK)
longbridge <investors-subcommand> 1067983 --format json           # Berkshire 13F
longbridge <investors-changes-subcommand> 1067983 --format json   # QoQ changes
longbridge <fund-holder-subcommand> AAPL.US --format json
longbridge <insider-trades-subcommand> TSLA.US --format json      # US only
longbridge <short-positions-subcommand> AAPL.US --format json     # US only
longbridge <broker-holding-subcommand> 700.HK --format json       # HK only

longbridge <broker-holding-daily-subcommand> 700.HK --format json

Output

Render in the user's language. Suggested layouts:

13F (investors) — when no CIK: AUM-ranked manager table. With CIK: top-N positions (ticker / value / shares / weight / change vs last filing). For changes: NEW / ADDED / REDUCED / EXITED grouped lists.

fund-holder — table sorted by weight: fund name / ticker / currency / weight % / report date. Highlight high-weight funds (> 1%).

insider-trades — chronological list (most recent first): date / insider / role / type (BUY/SELL/GRANT/...) / shares / price / value. Net buy vs sell summary at top.

short-positions — time-series table: date / short interest / short ratio / days-to-cover. Note trend (rising / falling).

broker-holding — for the --period view: top buy brokers and top sell brokers side by side. For detail: full list. For daily: a single broker's history.

When a result is empty, state so. Do not invent.

Error handling

MCP fallback

When the CLI binary is missing, fall back via the equivalent MCP tool. Tool names typically mirror CLI subcommand names (snake_case).

When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime — do not rely on hardcoded tool names.

If a name above does not resolve, fall back via the equivalent MCP tool when CLI is missing.
