longbridge-capital-flow

Today's capital flow time-series and order-size distribution for a single security.

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

Subcommands

A single capital command handles both modes — distribution snapshot (default) and time-series (--flow). Run longbridge capital --help to confirm.

CLI command	Returns
longbridge capital <SYMBOL> --format json	Cross-section snapshot: large / medium / small / super-large order buy & sell amounts.
longbridge capital <SYMBOL> --flow --format json	Today's main-capital net inflow / outflow time series.

Single symbol per call. Today's data only — no historical range.

When to use

• "今天 NVDA 主力净流入", "今日資金流" → capital --flow
• "看下 TSLA 大单分布", "大單/中單/小單" → capital (default snapshot)
• "看一下 700 资金面" (combined) → call both (with and without --flow) and merge
• "过去 30 天资金流" → unsupported; redirect to longbridge-kline (volume) or longbridge-quote (--index volume)
• "今天哪些股票主力大幅流入" (screener) → unsupported; ask user for a specific symbol

Workflow

1. Resolve a single symbol to <CODE>.<MARKET>.
2. Decide which mode: distribution snapshot (default), time-series (--flow), or both.
3. Call the Longbridge CLI directly (preferred) or fall back to MCP.
4. Summarise: net inflow direction (▲ / ▼), accumulated total, distribution skew. Cite Longbridge Securities.

CLI

longbridge capital NVDA.US                  --format json     # snapshot
longbridge capital TSLA.US --flow           --format json     # time series
# Combined view → call both and merge in the LLM

Output

The default snapshot returns a cross-section object; --flow returns a time-series array.

Field translations (LLM should map):

Field (likely)	简体	繁體	English
large_in / large_out	大单流入/流出	大單流入/流出	Large order in/out
medium_in / medium_out	中单流入/流出	中單流入/流出	Medium order in/out
small_in / small_out	小单流入/流出	小單流入/流出	Small order in/out
super_in / super_out	超大单流入/流出	超大單流入/流出	Super-large order in/out

(Field names follow Longbridge JSON; LLM maps to the user's language.)

Error handling

If longbridge is missing, fall back to MCP. Other stderr messages get relayed verbatim (auth issues → longbridge auth login; invalid symbol → re-check format).

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.
