Longbridge Quote

longbridge-quote

Real-time quote, static info, and valuation indices for Longbridge-supported securities (HK / US / A-share / Singapore).

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

When to use

Trigger on prompts asking about:

• Current price / change / volume — "NVDA 现在多少钱", "現在股價", "What's NVDA's price?"
• Industry / market cap / floats / EPS / BPS — "贵州茅台市值多少", "茅台屬於什麼行業", "AAPL EPS"
• Valuation indices (PE, PB, turnover rate, 5/10-day change, etc.) — "NVDA 的 PE", "700 換手率", "AAPL volume ratio"
• Trading status of a single security — "AAPL still trading?", "美股开盘了吗"

For 2–5 symbol comparison defer to longbridge-peer-comparison. For historical valuation percentile, defer to longbridge-valuation.

Symbol format

<CODE>.<MARKET>. Normalise before calling:

If the market is ambiguous, ask the user rather than guessing.

Subcommands

Run longbridge --help to see all available subcommands, then longbridge <subcommand> --help before calling. Types of data needed:

• Real-time quote data (last price, open, high, low, prev close, volume, turnover, trade status)
• Static reference data (name, industry, lot size, total/circulating shares, EPS, BPS, dividend yield, currency)
• Valuation indices (PE, PB, turnover rate, total market cap, change rates, etc.)

Always run longbridge <subcommand> --help first — every Longbridge CLI subcommand self-documents its arguments, defaults, and examples. Do not hard-code flag names from this SKILL.md if the CLI version may have evolved.

Workflow

1. Extract symbol(s) from the prompt; normalise each to <CODE>.<MARKET>.
2. Run longbridge --help to identify available subcommands, then longbridge <subcommand> --help to confirm flags.
3. Decide which subset of data is needed:
   • Quote only (price / change / volume) → real-time quote subcommand
   • Static (industry, market cap, EPS, BPS, dividend yield) → static reference subcommand
   • Indices (PE, PB, turnover rate, etc.) → valuation index subcommand (check --help for supported field names)
   • Combined ("full snapshot") → all three
4. Run them (parallel is fine when supported by the agent runtime). Each command returns a JSON array keyed by symbol.
5. Merge the per-symbol rows by symbol into a single object per security.
6. Translate to natural language; cite the source as Longbridge Securities / 数据来源:长桥证券 / 數據來源:長橋證券.

CLI examples

# Always check available flags first:
longbridge <subcommand> --help

# Then call with --format json — example structure (verify subcommand names and flags with --help):
longbridge <quote-subcommand>      NVDA.US --format json
longbridge <quote-subcommand>      NVDA.US 700.HK 600519.SH --format json   # multi-symbol
longbridge <static-subcommand>     600519.SH --format json
longbridge <calc-index-subcommand> NVDA.US --format json   # valuation indices; use --help for index field names

Run longbridge <calc-index-subcommand> --help to see all supported index field names. A reference cheat-sheet (with multilingual labels) lives in references/calc-index-fields.md.

Output

Each subcommand returns a JSON array, one object per requested symbol. Missing per-symbol values appear as "-" or null (not an error). When merging, key by symbol and emit a structure like:

{
  "symbol": "NVDA.US",
  "quote":      { "last": "...", "prev_close": "...", "volume": "...", ... },
  "static":     { "industry": "...", "eps": "...", "bps": "...", ... },
  "calc_index": { "pe_ttm": "...", "pb": "...", "total_market_value": "...", ... }
}

Error handling

MCP fallback

If the CLI binary is unavailable and the user has run claude mcp add --transport http longbridge https://openapi.longbridge.com/mcp, fall back to:

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.

MCP is slower (HTTP + OAuth) but does not depend on a local binary.
