XtData（XtQuant行情数据模块）

xtdata is the market data module of XtQuant, providing real-time and historical market data through the local miniQMT client.

⚠️ Requires miniQMT running locally. xtdata communicates with miniQMT via TCP to retrieve data.

安装

pip install xtquant

连接

from xtquant import xtdata

# Connect to the local miniQMT market data service
xtdata.connect()

Optionally specify a data directory:

# Manually specify the miniQMT data directory path
xtdata.data_dir = r'D:\QMT\userdata_mini'

API分类

The xtdata API is divided into three main categories:

• Subscription — subscribe_quote, subscribe_whole_quote: Register real-time data callbacks; data is continuously pushed until unsubscribed
• Retrieval — get_market_data_ex, get_local_data, get_full_tick, get_financial_data: Read data from local cache; returns immediately
• Download — download_history_data, download_financial_data: Download data from the server to local cache; blocks synchronously until complete

Key Pattern: When retrieving historical data, you must first download to local cache, then get from cache. For real-time data, use subscribe.

通用类型约定

• stock_code: 'SecurityCode.MarketCode' format, e.g. '600000.SH', '000001.SZ'
• period: 'tick', '1m', '5m', '15m', '30m', '1h', '1d', '1w', '1mon'
• start_time / end_time: 'YYYYMMDDHHmmss' or 'YYYYMMDD' format strings
• dividend_type: 'none' (no adjustment), 'front' (forward adjustment), 'back' (backward adjustment), 'front_ratio' (proportional forward adjustment), 'back_ratio' (proportional backward adjustment)

请求限制

• Historical data download requests are rate-limited; avoid excessive concurrent downloads.
• Batch queries (multiple stocks) are more efficient than looping one by one; batch mode is recommended.
• Full-market subscription (subscribe_whole_quote) may require Level2 data permissions for some data types.

下载历史数据

You must download data before retrieving it locally:

# Download daily K-line data
xtdata.download_history_data('000001.SZ', '1d', start_time='20240101', end_time='20240630')

# Download 1-minute K-line data
xtdata.download_history_data('000001.SZ', '1m', start_time='20240101', end_time='20240630')

# Download Tick data
xtdata.download_history_data('000001.SZ', 'tick', start_time='20240601', end_time='20240630')

下载退市/到期合约数据

# Use download_history_data2 to download data for delisted or expired contracts
xtdata.download_history_data2(['IC2312.IF'], '1d', start_time='20230101', end_time='20231231')

获取K线数据

# Retrieve market data (returns a dict of DataFrames keyed by stock code)
data = xtdata.get_market_data_ex(
    [],                    # field_list, empty list means all fields
    ['000001.SZ'],         # stock_list, list of stock codes
    period='1d',           # period: tick, 1m, 5m, 15m, 30m, 1h, 1d, 1w, 1mon
    start_time='20240101',
    end_time='20240630',
    count=-1,              # -1 means retrieve all data
    dividend_type='front',  # adjustment type: none, front, back, front_ratio, back_ratio
    fill_data=True         # whether to fill suspended trading data
)
df = data['000001.SZ']
# Returned fields: open, high, low, close, volume, amount, settelementPrice, openInterest, preClose, suspendFlag

获取最新交易日K线

# count=1 retrieves the latest single K-line bar
data = xtdata.get_market_data_ex([], ['000001.SZ'], period='1d', count=1)

获取本地缓存数据

# If data is already cached, read directly from local storage (no need to download again)
data = xtdata.get_local_data(
    field_list=[],
    stock_list=['000001.SZ'],
    period='1d',
    start_time='20240101',

使用技巧

• Before retrieving data for the first time, always call xtdata.download_history_data() to download to local cache.
• Downloaded data is cached locally — subsequent reads are extremely fast.
• xtdata.run() blocks the current thread — if you need to trade simultaneously, run it in a separate thread.
• Prefer get_market_data_ex (recommended) over get_local_data — the former supports more features like dividend adjustment.
• For delisted/expired contract data, use download_history_data2.
• Financial data timestamp notes: m_anntime = disclosure date, m_timetag = reporting period end date.
• Documentation: http://dict.thinktrader.net/nativeApi/xtdata.html

🤖 AI Agent 高阶使用指南

对于 AI Agent，在使用该量化/数据工具时应遵循以下高阶策略和最佳实践，以确保任务的高效完成：

1. 数据校验与错误处理

在获取数据或执行操作后，AI 应当主动检查返回的结果格式是否符合预期，以及是否存在缺失值（NaN）或空数据。

• 示例策略：在通过 API 获取数据框（DataFrame）后，使用 if df.empty: 进行校验；捕获 Exception 以防网络或接口错误导致进程崩溃。

2. 多步组合分析

AI 经常需要进行宏观经济分析或跨市场对比。应善于将当前接口与其他数据源或工具组合使用。

• 示例策略：先获取板块或指数的宏观数据，再筛选成分股，最后对具体标的进行深入的财务或技术面分析，形成完整的决策链条。

3. 构建动态监控与日志

对于交易和策略类任务，AI 可以定期拉取数据并建立监控机制。

• 示例策略：使用循环或定时任务检查特定标的的异动（如涨跌停、放量），并在发现满足条件的信号时输出结构化日志或触发预警。
