# 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

```bash
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.
