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
- Identify the symbol, date range, and indicator expression from the prompt.
- Run
longbridge quant run --help to check supported functions and flags before constructing the call.
- Build the
--script string using Pine Script v6 ta.* built-ins (e.g. ta.macd, ta.rsi, ta.ema, ta.bb).
- For multi-indicator requests, wrap them in a list:
"[ta.macd(...), ta.rsi(...)]".
- 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.

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.
