longbridge-kline

Historical candlesticks and today's intraday curve for Longbridge-supported securities (HK / US / A-share / Singapore). Does not support options, warrants, or indices — defer to longbridge-derivatives (derivatives) or longbridge-quote (indices).

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

Subcommands

Run longbridge kline --help to confirm current period values, defaults, and aliases.

CLI command	Use when
longbridge kline <SYMBOL> --period <P> --count <N> --format json	Latest N candles. Periods: 1m / 5m / 15m / 30m / 1h / day / week / month / year.
longbridge kline history <SYMBOL> --start YYYY-MM-DD --end YYYY-MM-DD --period <P> --format json	OHLCV across an explicit date range (sub-subcommand).
longbridge intraday <SYMBOL> --format json	Today's per-minute curve (price + volume + avg_price).

Period aliases: minute=1m, hour=1h, d/1d=day, w=week, m/1mo=month, y=year. --adjust none (default) or --adjust forward for 前复权 / 前復權.

When to use

• "NVDA 最近一周走势", "近一年走勢", "AAPL 1-month chart" → kline --period day
• "TSLA 5 分钟 K", "近 100 根 5 分钟" → kline --period 5m --count 100
• "今天 700.HK 分时图", "AAPL today's intraday" → intraday
• "AAPL 2024 年 1-12 月日 K" (explicit dates) → kline history --start --end
• "前复权日 K" → add --adjust forward

Workflow

1. Resolve the symbol to <CODE>.<MARKET> (see longbridge-quote for the rules).
2. Pick the form:
   • Explicit start/end dates → kline history.
   • "Today" / "intraday" → intraday.
   • Otherwise → kline with sensible defaults (--period day --count 100).
3. Map natural-language windows to (period, count). Examples: "最近一周" → day,7, "最近一年" → day,252, "月 K" → month,100.
4. Call the Longbridge CLI directly (preferred) or fall back to MCP.
5. Translate datasets into prose (range high / low, net move, volume note); use ▲ / ▼ for direction. Cite Longbridge Securities / 数据来源:长桥证券 / 數據來源:長橋證券.

CLI

longbridge kline         NVDA.US --period day --count 100             --format json
longbridge kline         700.HK  --period 5m  --count 100 --adjust forward --format json
longbridge kline history NVDA.US --start 2025-01-01 --end 2025-12-31  --format json
longbridge intraday      700.HK                                       --format json

Output

longbridge kline ... --format json returns a list of OHLCV rows:

[
  {"time": "...", "open": "...", "high": "...", "low": "...", "close": "...", "volume": "...", "turnover": "..."}
]

intraday rows are {time, price, volume, turnover, avg_price}.

Error handling

If longbridge is not installed, the shell returns a command not found error → fall back to MCP (see below) or tell the user to install longbridge-terminal. If longbridge prints Error: ... to stderr, surface the message to the user — common causes:

• Error: not logged in / unauthorized → user runs longbridge auth login.
• Error: invalid symbol / param_error → re-check the <CODE>.<MARKET> format.

MCP fallback

CLI subcommand	MCP tool
kline	mcp__longbridge__candlesticks
kline history	mcp__longbridge__history_candlesticks_by_offset or mcp__longbridge__history_candlesticks_by_date
intraday	mcp__longbridge__intraday
