An open-source, ultra-fast, and efficient quantitative trading framework in C++/Python

English | 简体中文

Hikyuu Quant Framework builds on mature systematic trading and portfolio management concepts, with a core focus on a fast research workflow for strategy (or asset) portfolios. It decomposes quantitative analysis into independently replaceable strategy parts — market environment, signals, stop-loss / take-profit, money management, profit goals, slippage, multi-factor models and fund allocation — which you can freely combine into your own strategy library and validate through backtesting.

⚠️ Disclaimer: This project is an open-source financial technology research tool. It is intended for personal study, academic research and data analysis only. It does not constitute any investment advice or trading guidance, and it does not provide or embed any securities trading service. The framework only offers generic interface extension capability; users are advised to connect only to compliant trading terminals provided by licensed institutions. Any trading interface, extension or actual operation added or developed by the user is entirely at the user's own risk and legal responsibility. Connecting to illegal trading channels or using the framework for non-compliant trading scenarios is strictly prohibited.

• Python 3.10+ (3.9 and below are no longer supported for pip installation since 2.8.0)
• Windows / Linux / macOS (Linux: Ubuntu 24.04+)
• Main dependencies are installed automatically: numpy, pandas, matplotlib, PySide6, tables, etc.

pip install hikyuu

If the download is slow (for users in China), use a mirror:

pip install hikyuu -i https://pypi.tuna.tsinghua.edu.cn/simple

Import historical A-share market data with either method:

# Graphical interface (recommended for first use; it generates the configuration file)
HikyuuTDX

# Command line (requires having run HikyuuTDX once to generate the configuration)
importdata

ℹ️ Data coverage: HikyuuTDX downloads China A-share historical data only and needs a one-time initial configuration in the GUI. Overseas markets (US stocks, etc.) are not available yet and will be supported gradually.

from hikyuu.interactive import *

# Create a simulated trading account for backtesting, with initial capital of 300,000
my_tm = crtTM(init_cash=300000)

# Create a signal indicator (fast line: 5-day EMA; slow line: 10-day EMA)
# Buy when the fast line crosses above the slow line, sell otherwise
my_sg = SG_Flex(EMA(CLOSE(), n=5), slow_n=10)

# Buy a fixed 1000 shares each time
my_mm = MM_FixedCount(1000)

# Create the trading system and run it
sys = SYS_Simple(tm=my_tm, sg=my_sg, mm=my_mm)
sys.run(sm['sz000001'], Query(-150))

Powerful features for your quantitative trading research

Hikyuu provides a lightweight abstraction over systematic trading methods, encapsulating the market environment, signal generators, stop-loss / take-profit, money management, profit goals, slippage and fund allocation as independently replaceable strategy parts. You can combine them freely, backtest efficiently, and focus on the effect and impact of a single part during research. See "Core parts of the systematic trading architecture" below for the complete list.

The project consists of three parts: a high-performance C++ core library, the Python interface layer (hikyuu), and the interactive exploration tool.

• Measured on an AMD 7950x: loading the full A-share market (19.13 million daily K-line bars) and computing and summing the 20-day moving average for the first time takes only 6 seconds; once the data is warm, the same operation takes only 166 milliseconds (📊 Performance benchmark details, article in Chinese).
• C++ core library: ships with a complete strategy framework, native multi-threading and multi-core acceleration, leaving room to scale for very high computing demands. The core library can also be used standalone, helping developers build custom quantitative tools quickly.
• Python interface layer (hikyuu): a lightweight wrapper around the C++ core with TA-Lib integrated; converts seamlessly to and from numpy and pandas, so it plugs into the mainstream Python data analysis ecosystem.
• hikyuu.interactive: the interactive exploration tool, with built-in visualization of candlesticks, indicators and signals, suitable for rapid strategy validation and backtest analysis.

Both object-oriented and command-line styles are supported. Especially during strategy exploration, the command-line style is minimal and expressive, letting you validate ideas and iterate faster.

Combining Python + Jupyter with a cloud server gives you a fully self-controlled cloud quant platform. Once deployed, access it anywhere (phone, tablet or computer) and turn new ideas into practice quickly. It also integrates with mature AI and data analysis tools such as numpy, scipy, pandas and TensorFlow for building intelligent quantitative systems. You can customize the interface or deploy it as a service as needed.

Four storage backends are currently supported: HDF5, MySQL, ClickHouse and SQLite, with HDF5 as the default (compact, fast to read and write, and easy to back up). ClickHouse is available through a plugin: it reads and writes faster than HDF5 and uses far less space than MySQL, making it a better fit for minute-level and higher-frequency data.

A complete strategy backtest system takes only a few lines of code — the intuitive API makes strategy development more efficient.

Released under the Apache 2.0 license, with fully auditable source code. Core data and strategies stay entirely under your local control; the C++ core library can be used standalone, so you can build your own client tools without worrying about third-party platform restrictions.

Rigorously architected around systematic trading concepts; every part can be replaced and combined freely
