longbridge-quant

Server-side quantitative indicator runner: execute Pine Script v6 syntax subset on historical K-line data via Longbridge Securities servers.

⚠️ Beta feature: longbridge quant run may return internal server error if the feature is not yet enabled for your account. Contact Longbridge support to enable quantitative script access if needed.

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

When to use

• "帮我算 TSLA 的 MACD", "計算 RSI(14)", "run MACD on NVDA" → longbridge quant run with a built-in ta.* function
• "用 Pine Script 算布林带", "自定义指标脚本", "custom Pine Script indicator" → pass a script string or pipe a .pine file
• "我想看近一年 EMA20", "EMA 20 for the past year" → set --start / --end accordingly

For raw OHLCV data without indicator logic, defer to longbridge-kline. For visual chart output, defer to longbridge-kline.

Workflow

1. Identify the symbol, date range, and indicator expression from the prompt.
2. Run longbridge quant run --help to check supported functions and flags before constructing the call.
3. Build the --script string using Pine Script v6 ta.* built-ins (e.g. ta.macd, ta.rsi, ta.ema, ta.bb).
4. For multi-indicator requests, wrap them in a list: "[ta.macd(...), ta.rsi(...)]".
5. Return JSON output; summarise the last N rows in a date-sorted table.

CLI

Run longbridge quant run --help before constructing calls — it is the canonical source for supported functions, operators, and flags.

# Inspect supported functions and flags first
longbridge quant run --help

# Single built-in indicator — 20-day EMA
longbridge quant run AAPL.US --start 2025-01-01 --end 2025-12-31 \
  --script "ta.ema(close, 20)" --format json

# RSI(14) for a date range
longbridge quant run TSLA.US --start 2026-01-01 --end 2026-04-30 \
  --script "ta.rsi(close, 14)" --format json

# Multi-indicator: MACD + RSI combined
longbridge quant run NVDA.US --start 2025-01-01 --end 2026-01-01 \
  --script "[ta.macd(close,12,26,9), ta.rsi(close,14)]" --format json

# Bollinger Bands
longbridge quant run 700.HK --start 2025-06-01 --end 2025-12-31 \
  --script "ta.bb(close, 20, 2)" --format json

# Pipe a custom Pine Script file
cat myindicator.pine | longbridge quant run AAPL.US \
  --start 2025-01-01 --end 2025-12-31 --format json

Note: longbridge quant run uses a Pine Script v6 syntax subset. Not all Pine Script v6 functions are available — check --help for the full supported function and operator list.

Output

Present results as a date-sorted table with indicator columns. Example layout:

Date	EMA(20)	RSI(14)
2025-12-31	248.32	61.4
2025-12-30	247.89	59.8

• Always show the date range queried and the symbol.
• For multi-output indicators (e.g. MACD returns MACD line / signal / histogram), show all components as separate columns.
• Cite Longbridge Securities as the data source.

Error handling

Situation	简体回复 / 繁体回复 / English reply
command not found: longbridge	请安装 longbridge-terminal / 請安裝 longbridge-terminal / Install longbridge-terminal first; fall back to MCP if configured.
unsupported function / parse error	指定函数不在支持列表，请运行 --help 查看可用函数 / 指定函數不在支援清單，請執行 --help 查看可用函數 / Function not supported — run longbridge quant run --help for the full list.
not logged in / unauthorized	运行 longbridge auth login / 執行 longbridge auth login / Run longbridge auth login.
Empty result	指定日期范围内无数据 / 指定日期範圍內無數據 / No data for the requested date range.
Other stderr	Surface verbatim — never silently retry.

MCP fallback

When the CLI binary is missing, fall back via the equivalent MCP tool:

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.

If the tool name does not resolve, ask the user to install the CLI.
