Longbridge Market Data

Real-time and historical market data for HK / US / A-share / Singapore via the Longbridge CLI.

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

> RULE: Response language priority: English is the default when language is ambiguous. If the user input is only a slash command, command name, ticker / symbol, or contains no natural-language language signal, you MUST respond in English. Do not infer Chinese from trigger keywords, skill metadata, or examples.

> Data-source scope: prefer the configured Longbridge connection for supported data. If required timestamps, ADR ratios, benchmark rates or history are unavailable, disclose the gap; use an authorized primary source or leave the calculation incomplete. Do not fill current financial inputs from model memory.

When to use

Trigger when the user asks about: stock price / quote, K-line / candlestick chart, order book depth, recent trades / ticks, intraday capital flow, market sentiment index, trading session status, exchange rates, IPO calendar / subscription, security lists, ADR premium, or FX carry trade analysis.

Frameworks

ADR Premium Analysis

Cross-market pricing between US ADR, HK H-share, and A-shares. See [references/adr-premium.md](https://github.com/longbridge/skills/tree/main/skills/longbridge-market-data/references/adr-premium.md).

FX Carry Trade

Carry trade opportunity analysis using spot rates, forward points, and interest rate differentials. See [references/fx-carry.md](https://github.com/longbridge/skills/tree/main/skills/longbridge-market-data/references/fx-carry.md).

Error handling

| Situation | Response |

|---|---|

| command not found: longbridge | Install longbridge-terminal: brew tap longbridge/tap && brew install longbridge/tap/longbridge-terminal |

| not logged in / unauthorized | Run longbridge auth login |

| Empty result | "No data returned — verify the symbol format is <CODE>.<MARKET> (e.g. NVDA.US, 700.HK)" |

| Other stderr | Summarize the error after removing tokens/account identifiers — do not retry silently |

MCP fallback

If longbridge is unavailable, discover tools on an already configured Longbridge MCP connection and check equivalent read capability. Do not assume every command has a counterpart: subscriptions is CLI-session-only. Missing tools are an availability limitation, not authority to configure a new service.

Data checks and example

For a request such as “compare the ADR and Hong Kong listing”, return instrument identifiers, quote timestamps/time zones, currency, FX direction and timestamp, and verified depositary ratio before computing a common-unit premium. Label delayed, stale, missing and closed-market observations. A price gap is not an executable arbitrage: conversion eligibility, fees, settlement, borrowing and trading-hour overlap matter. Read-only analysis does not authorize IPO orders or trading. Account results are private.

Limitations

• Use this skill only when the task clearly matches its upstream source and local project context.
• Treat all market, trading, instrument, account, or portfolio examples as technical API examples only, not financial advice or a recommendation to trade.

• Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
• Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
