longbridge-depth

Orderbook depth, broker queue (HK-only), and tick-by-tick trades.

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

Subcommands

broker_id integers can be translated to names via longbridge-security-list → participants.

When to use

• "看下 700.HK 的盘口", "TSLA 5 档买卖盘" → depth
• "茅台经纪商队列" — non-HK symbol → tell user "broker queue is HK-only" and switch to depth
• "NVDA 最近 50 笔成交", "腾讯 tick 数据" → trades --count 50
• "700 全部盘口", "microstructure overview" → call depth, brokers (if HK), and trades and merge the results

Workflow

1. Resolve the symbol to <CODE>.<MARKET>.
2. Pick the subcommand by user intent (table above). For an "overview" intent, run depth + brokers (HK-only) + trades and merge.
3. Off-hours warning: outside trading hours, depth is the closing snapshot and trades are the last N of the previous session — call this out explicitly when responding.
4. Call the Longbridge CLI directly (preferred) or fall back to MCP.
5. Render depth as a bid / ask table; describe trades as a direction summary (buy-dominant / sell-dominant) plus the latest few rows. Cite Longbridge Securities.

CLI

longbridge depth   700.HK                  --format json
longbridge brokers 700.HK                  --format json   # HK-only
longbridge trades  700.HK --count 50       --format json

Always pass --format json so the output is machine-parseable.

Output

• depth / brokers: {asks: [...], bids: [...]} (brokers[i] includes a broker_id array)
• trades: array of trade rows (time / price / volume / direction / type)

Error handling

If longbridge is missing, fall back to MCP. If stderr surfaces "broker queue not supported" / "non-HK" on a brokers call, explain that broker queues are HK-only and switch to depth. Other stderr messages (auth / invalid symbol) get relayed verbatim.

MCP fallback

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-only extensions are available; discover them from the MCP server's tool list at runtime.
