XtQuant（迅投QMT Python SDK）

XtQuant is the Python SDK for the QMT/miniQMT quantitative trading platform, developed by ThinkTrader (XunTou Technology). It contains two core modules:

• xtdata — Market Data Module: real-time quotes, historical K-lines, tick data, Level 2 data, financial data, sector management
• xttrade — Trading Module: order placement, position/order queries, account management, margin trading, futures/options, smart algorithms

⚠️ Requires miniQMT or QMT client running on Windows. XtQuant connects to the QMT process via local TCP. You need QMT/miniQMT access enabled by your broker.

安装

pip install xtquant

You can also download from the official website: http://dict.thinktrader.net/nativeApi/download_xtquant.html

核心模块参考

快速入门 — 行情数据

from xtquant import xtdata

# Connect to local miniQMT (default: localhost)
xtdata.connect()

# Download historical K-line data (must download to local cache before first access)
xtdata.download_history_data('000001.SZ', '1d', start_time='20240101', end_time='20240630')

# Get local K-line 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',
    start_time='20240101',
    end_time='20240630',
    dividend_type='front'  # 复权类型: none (unadjusted), front (forward-adjusted), back (backward-adjusted), front_ratio (proportional forward), back_ratio (proportional backward)
)
print(data['000001.SZ'])

实时行情订阅

def on_data(datas):
    """Quote data callback function, receives pushed real-time data"""
    for stock_code, data in datas.items():
        print(stock_code, data)

# Subscribe to tick data for a single stock
xtdata.subscribe_quote('000001.SZ', period='tick', callback=on_data)

# Subscribe to full-market quote push
xtdata.subscribe_whole_quote(['SH', 'SZ'], callback=on_data)

xtdata.run()  # Block the current thread, continuously receiving callback data

财务数据

# First download financial data to local cache
xtdata.download_financial_data(['000001.SZ'])
# Then retrieve financial data from local cache
data = xtdata.get_financial_data(['000001.SZ'])
# Available financial reports: Balance (balance sheet), Income (income statement), CashFlow (cash flow statement),
# PershareIndex (per-share indicators), CapitalStructure (capital structure), TOP10HOLDER (top 10 shareholders),
# TOP10FLOWHOLDER (top 10 tradable shareholders), SHAREHOLDER (shareholder count)

合约信息与板块

# Get detailed instrument info (name, price limits, tick size, etc.)
info = xtdata.get_instrument_detail('000001.SZ')
# Get security type (stock/index/fund/bond, etc.)
itype = xtdata.get_instrument_type('000001.SZ')
# Get list of stocks in a sector
stocks = xtdata.get_stock_list_in_sector('沪深A股')
# Get list of trading dates
days = xtdata.get_trading_dates('SH', start_time='20240101', end_time='20240630')

xtdata接口模式

The market data module follows a unified download → retrieve pattern:

1. Subscribe (subscribe): subscribe_quote, subscribe_whole_quote — real-time push
2. Download (download): download_history_data, download_financial_data — download from server to local cache (synchronous/blocking)
3. Retrieve (get): get_market_data_ex, get_financial_data — read from local cache (fast)

xttrade回调系统

Register an XtQuantTraderCallback subclass to receive real-time push notifications:

高级功能

• Smart Algorithm Trading: Execute algorithmic orders such as VWAP via smart_algo_order_async
• Securities Lending: Query available securities, apply for lending, manage contracts
• Bank-Securities Transfer: Transfer funds between bank and securities accounts
• CTP Internal Transfer: Transfer funds between futures and options accounts
• Custom Sectors: Create, manage, and query custom stock groups
• Level 2 Data: l2quote, l2order, l2transaction, l2quoteaux, l2orderqueue, l2thousand (1000-level order book), limitupperformance (consecutive limit-up tracking), snapshotindex, hfiopv, fullspeedorderbook

使用技巧

• miniQMT must be running on Windows — xtquant connects via local TCP.
• session_id must be unique per strategy — different strategies need different IDs.
• connect() is a one-time connection — it does not auto-reconnect after disconnection; you must call it again manually.
• Always call subscribe(account) to receive trading push callbacks.
• Data is cached locally after download — subsequent reads are extremely fast.
• Use dividend_type='front' to get forward-adjusted K-line data.
• In push callbacks, use async query methods to avoid deadlocks.

🤖 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。
