Only fall back to WebSearch when Longbridge news is insufficient (e.g., breaking news not yet indexed, macro events unrelated to a specific symbol). --- ## Choose the Right Tool ``` User wants to... → Use ───────────────────────────────────────────────────────────────── Quick quote / one-off data lookup CLI Interactive terminal workflows CLI Script market data, save to file CLI + jq (or Python SDK) Loops, conditions, transformations Python SDK (sync) Async pipelines, concurrent fetches Python SDK (async) Production service, high throughput Rust SDK Real-time WebSocket subscription loop SDK (Python or Rust) Programmatic order strategy SDK Talk to AI about stocks (no code) MCP (hosted or self-hosted) Use Cursor/Claude for trading analysis MCP Add Longbridge API docs to IDE/RAG LLMs.txt / Markdown API ``` ## Symbol Format `.` — applies to all tools. | Market | Suffix | Examples | | -------------- | ------ | ------------------------------- | | Hong Kong | `HK` | `700.HK`, `9988.HK`, `2318.HK` | | United States | `US` | `TSLA.US`, `AAPL.US`, `NVDA.US` | | China Shanghai | `SH` | `600519.SH`, `000001.SH` | | China Shenzhen | `SZ` | `000568.SZ`, `300750.SZ` | | Singapore | `SG` | `D05.SG`, `U11.SG` | | Crypto | `HAS` | `BTCUSD.HAS`, `ETHUSD.HAS` | ## Reference Files ### CLI (Terminal) - **Overview** — install, auth, output formats, patterns: [references/cli/overview.md](references/cli/overview.md) **Always use `longbridge --help` to list available commands, and `longbridge --help` for specific options and flags.** Do not rely on hardcoded documentation — the CLI's built-in help is always up-to-date. ### Python SDK - **Overview** — install, Config, auth, HttpClient: [references/python-sdk/overview.md](references/python-sdk/overview.md) - **QuoteContext** — all quote methods + subscriptions: [references/python-sdk/quote-context.md](references/python-sdk/quote-context.md) - **TradeContext** — orders, account, executions: [references/python-sdk/trade-context.md](references/python-sdk/trade-context.md) - **Types & Enums** — Period, OrderType, SubType, push types: [references/python-sdk/types.md](references/python-sdk/types.md) ### Rust SDK - **Overview** — Cargo.toml, Config, auth, error handling: [references/rust-sdk/overview.md](references/rust-sdk/overview.md) - **QuoteContext** — all methods, SubFlags, PushEvent: [references/rust-sdk/quote-context.md](references/rust-sdk/quote-context.md) - **TradeContext** — orders, SubmitOrderOptions builder, account: [references/rust-sdk/trade-context.md](references/rust-sdk/trade-context.md) - **Content** — news, filings, topics (ContentContext + Python fallback): [references/rust-sdk/content.md](references/rust-sdk/content.md) - **Types & Enums** — all Rust enums and structs: [references/rust-sdk/types.md](references/rust-sdk/types.md) ### AI Integration - **MCP** — hosted service, self-hosted server, setup & auth: [references/mcp.md](references/mcp.md) - **LLMs & Markdown** — llms.txt, `open.longbridge.com` doc Markdown, `longbridge.com` live news/quote pages (`.md` suffix + Accept header), Cursor/IDE integration: [references/llm.md](references/llm.md) Load specific reference files on demand — do not load all at once. --- ## Related skills The skills below are siblings in the `longbridge/skills` family. If they're installed, defer to them for the listed user intents — they're more specialised and produce better-formatted output. If they're **not** installed, this skill's own CLI workflow above can handle the same queries with less specialised formatting; the foundation skill remains usable standalone. | If the user wants … | Use | |---|---| | Live quote / static reference / valuation indices for a single name | [`longbridge-quote`](../longbridge-quote) | | Candlestick / intraday chart | [`longbridge-kline`](../longbridge-kline) | | Orderbook depth / brokers / tick trades | [`longbridge-depth`](../longbridge-depth) | | Capital flow / large-order distribution | [`longbridge-capital-flow`](../longbridge-capital-flow) | | Market-level state — open / close, sentiment temperature, calendar | [`longbridge-market-temp`](../longbridge-market-temp) | | Options / warrants | [`longbridge-derivatives`](../longbridge-derivatives) | | US overnight-eligible securities catalog / HK broker dictionary | [`longbridge-security-list`](../longbridge-security-list) | | Stock + fund holdings, multi-currency assets, margin ratio, max-buy quantity | [`longbridge-positions`](../longbridge-positions) | | Today's / historical orders, executions, cash flow | [`longbridge-orders`](../longbridge-orders) | | Read-only watchlist groups | [`longbridge-watchlist`](../longbridge-watchlist) | | Watchlist mutations (create / rename / add / remove) | [`longbridge-watchlist-admin`](../longbridge-watchlist-admin) | | Active real-time WebSocket subscription diagnostics | [`longbridge-subscriptions`](../longbridge-subscriptions) | | "Is X expensive?" — historical PE / PB percentile, industry context | [`longbridge-valuation`](../longbridge-valuation) | | 5-dimension fundamentals (KPIs, dividends, consensus, ratings) | [`longbridge-fundamental`](../longbridge-fundamental) | | 2–5 symbol comparison matrix | [`longbridge-peer-comparison`](../longbridge-peer-comparison) | | Account-level P&L and contribution analysis | [`longbridge-portfolio`](../longbridge-portfolio) | | Classified news + filings + community sentiment for a single name | [`longbridge-news`](../longbridge-news) | | Daily incremental briefing across the watchlist | [`longbridge-catalyst-radar`](../longbridge-catalyst-radar) | | Institutional-grade post-earnings DOCX report (8–12 pages) | [`longbridge-earnings`](../longbridge-earnings) | This skill (`longbridge`) stays in scope when the user asks about: SDK syntax (Python / Rust), MCP server setup, LLMs.txt / IDE / RAG integration, raw CLI subcommand discovery, or anything cross-cutting that doesn't map cleanly to one specialised skill.
