New features under development(order by estimated release time). Your feedbacks about the features are very important.

Framework of Qlib

At the module level, Qlib is a platform that consists of the above components. The components are designed as loose-coupled modules, and each component could be used stand-alone.

Name Description
Infrastructure layer Infrastructure layer provides underlying support for Quant research. DataServer provides a high-performance infrastructure for users to manage and retrieve raw data. Trainer provides a flexible interface to control the training process of models, which enable algorithms to control the training process.
Workflow layer Workflow layer covers the whole workflow of quantitative investment. Information Extractor extracts data for models. Forecast Model focuses on producing all kinds of forecast signals (e.g. alpha, risk) for other modules. With these signals Decision Generator will generate the target trading decisions(i.e. portfolio, orders) to be executed by Execution Env (i.e. the trading market). There may be multiple levels of Trading Agent and Execution Env (e.g. an order executor trading agent and intraday order execution environment could behave like an interday trading environment and nested in daily portfolio management trading agent and interday trading environment )
Interface layer Interface layer tries to present a user-friendly interface for the underlying system. Analyser module will provide users detailed analysis reports of forecasting signals, portfolios and execution results
  • The modules with hand-drawn style are under development and will be released in the future.
  • The modules with dashed borders are highly user-customizable and extendible.

(p.s. framework image is created with https://draw.io/)

Quick Start

This quick start guide tries to demonstrate

  1. It's very easy to build a complete Quant research workflow and try your ideas with Qlib.
  2. Though with public data and simple models, machine learning technologies work very well in practical Quant investment.

Here is a quick demo shows how to install Qlib, and run LightGBM with qrun. But, please make sure you have already prepared the data following the instruction.


This table demonstrates the supported Python version of Qlib:

install with pip install from source plot
Python 3.7 :heavy_check_mark: :heavy_check_mark: :heavy_check_mark:
Python 3.8 :heavy_check_mark: :heavy_check_mark: :heavy_check_mark:
Python 3.9 :x: :heavy_check_mark: :x:


  1. Conda is suggested for managing your Python environment.
  2. Please pay attention that installing cython in Python 3.6 will raise some error when installing Qlib from source. If users use Python 3.6 on their machines, it is recommended to upgrade Python to version 3.7 or use conda's Python to install Qlib from source.
  3. For Python 3.9, Qlib supports running workflows such as training models, doing backtest and plot most of the related figures (those included in notebook). However, plotting for the model performance is not supported for now and we will fix this when the dependent packages are upgraded in the future.
  4. QlibRequires tables package, hdf5 in tables does not support python3.9.

Install with pip

Users can easily install Qlib by pip according to the following command.

  pip install pyqlib

Note: pip will install the latest stable qlib. However, the main branch of qlib is in active development. If you want to test the latest scripts or functions in the main branch. Please install qlib with the methods below.

Install from source

Also, users can install the latest dev version Qlib by the source code according to the following steps:

  • Before installing Qlib from source, users need to install some dependencies:

    pip install numpy
    pip install --upgrade  cython
  • Clone the repository and install Qlib as follows.

    git clone https://github.com/microsoft/qlib.git && cd qlib
    pip install .

    Note: You can install Qlib with python setup.py install as well. But it is not the recommanded approach. It will skip pip and cause obscure problems. For example, only the command pip install . can overwrite the stable version installed by pip install pyqlib, while the command python setup.py install can't.

Tips: If you fail to install Qlib or run the examples in your environment, comparing your steps and the CI workflow may help you find the problem.

Data Preparation

Load and prepare data by running the following code:

Get with module

# get 1d data
python -m qlib.run.get_data qlib_data --target_dir ~/.qlib/qlib_data/cn_data --region cn

# get 1min data
python -m qlib.run.get_data qlib_data --target_dir ~/.qlib/qlib_data/cn_data_1min --region cn --interval 1min

Get from source

# get 1d data
python scripts/get_data.py qlib_data --target_dir ~/.qlib/qlib_data/cn_data --region cn

# get 1min data
python scripts/get_data.py qlib_data --target_dir ~/.qlib/qlib_data/cn_data_1min --region cn --interval 1min

This dataset is created by public data collected by crawler scripts, which have been released in the same repository. Users could create the same dataset with it. Description of dataset

Please pay ATTENTION that the data is collected from Yahoo Finance, and the data might not be perfect. We recommend users to prepare their own data if they have a high-quality dataset. For more information, users can refer to the related document.

Automatic update of daily frequency data (from yahoo finance)

This step is Optional if users only want to try their models and strategies on history data.

It is recommended that users update the data manually once (--trading_date 2021-05-25) and then set it to update automatically.

NOTE: Users can't incrementally update data based on the offline data provided by Qlib(some fields are removed to reduce the data size). Users should use yahoo collector to download Yahoo data from scratch and then incrementally update it.

For more information, please refer to: yahoo collector

  • Automatic update of data to the "qlib" directory each trading day(Linux)

    • use crontab: crontab -e

    • set up timed tasks:

      * * * * 1-5 python <script path> update_data_to_bin --qlib_data_1d_dir <user data dir>
      • script path: scripts/data_collector/yahoo/collector.py
  • Manual update of data

    python scripts/data_collector/yahoo/collector.py update_data_to_bin --qlib_data_1d_dir <user data dir> --trading_date <start date> --end_date <end date>
    • trading_date: start of trading day
    • end_date: end of trading day(not included)

Auto Quant Research Workflow

Qlib provides a tool named qrun to run the whole workflow automatically (including building dataset, training models, backtest and evaluation). You can start an auto quant research workflow and have a graphical reports analysis according to the following steps:

  1. Quant Research Workflow: Run qrun with lightgbm workflow config (workflow_config_lightgbm_Alpha158.yaml as following.

      cd examples  # Avoid running program under the directory contains `qlib`
      qrun benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml

    If users want to use qrun under debug mode, please use the following command:

    python -m pdb qlib/workflow/cli.py examples/benchmarks/LightGBM/workflow_config_lightgbm_Alpha158.yaml

    The result of qrun is as follows, please refer to Intraday Trading for more details about the result.

    'The following are analysis results of the excess return without cost.'
    mean               0.000708
    std                0.005626
    annualized_return  0.178316
    information_ratio  1.996555
    max_drawdown      -0.081806
    'The following are analysis results of the excess return with cost.'
    mean               0.000512
    std                0.005626
    annualized_return  0.128982
    information_ratio  1.444287
    max_drawdown      -0.091078

    Here are detailed documents for qrun and workflow.

  2. Graphical Reports Analysis: Run examples/workflow_by_code.ipynb with jupyter notebook to get graphical reports

    • Forecasting signal (model prediction) analysis

      • Cumulative Return of groups Cumulative Return
      • Return distribution long_short
      • Information Coefficient (IC) Information Coefficient Monthly IC IC
      • Auto Correlation of forecasting signal (model prediction) Auto Correlation
    • Portfolio analysis

      • Backtest return Report
    • Explanation of above results

Building Customized Quant Research Workflow by Code

The automatic workflow may not suit the research workflow of all Quant researchers. To support a flexible Quant research workflow, Qlib also provides a modularized interface to allow researchers to build their own workflow by code. Here is a demo for customized Quant research workflow by code.

Main Challenges & Solutions in Quant Research

Quant investment is an very unique scenario with lots of key challenges to be solved. Currently, Qlib provides some solutions for several of them.

Forecasting: Finding Valuable Signals/Patterns

Accurate forecasting of the stock price trend is a very important part to construct profitable portfolios. However, huge amount of data with various formats in the financial market which make it challenging to build forecasting models.

An increasing number of SOTA Quant research works/papers, which focus on building forecasting models to mine valuable signals/patterns in complex financial data, are released in Qlib

Quant Model (Paper) Zoo

Here is a list of models built on Qlib.

Your PR of new Quant models is highly welcomed.

The performance of each model on the Alpha158 and Alpha360 dataset can be found here.

Run a single model

All the models listed above are runnable with Qlib. Users can find the config files we provide and some details about the model through the benchmarks folder. More information can be retrieved at the model files listed above.

Qlib provides three different ways to run a single model, users can pick the one that fits their cases best:

  • Users can use the tool qrun mentioned above to run a model's workflow based from a config file.

  • Users can create a workflow_by_code python script based on the one listed in the examples folder.

  • Users can use the script run_all_model.py listed in the examples folder to run a model. Here is an example of the specific shell command to be used: python run_all_model.py run --models=lightgbm, where the --models arguments can take any number of models listed above(the available models can be found in benchmarks). For more use cases, please refer to the file's docstrings.

    • NOTE: Each baseline has different environment dependencies, please make sure that your python version aligns with the requirements(e.g. TFT only supports Python 3.6~3.7 due to the limitation of tensorflow==1.15.0)

Run multiple models

Qlib also provides a script run_all_model.py which can run multiple models for several iterations. (Note: the script only support Linux for now. Other OS will be supported in the future. Besides, it doesn't support parallel running the same model for multiple times as well, and this will be fixed in the future development too.)

The script will create a unique virtual environment for each model, and delete the environments after training. Thus, only experiment results such as IC and backtest results will be generated and stored.

Here is an example of running all the models for 10 iterations:

python run_all_model.py run 10

It also provides the API to run specific models at once. For more use cases, please refer to the file's docstrings.

Adapting to Market Dynamics

Due to the non-stationary nature of the environment of the financial market, the data distribution may change in different periods, which makes the performance of models build on training data decays in the future test data. So adapting the forecasting models/strategies to market dynamics is very important to the model/strategies' performance.

Here is a list of solutions built on Qlib.

Quant Dataset Zoo

Dataset plays a very important role in Quant. Here is a list of the datasets built on Qlib:

Dataset US Market China Market

Here is a tutorial to build dataset with Qlib. Your PR to build new Quant dataset is highly welcomed.

More About Qlib

If you want to have a quick glance at the most frequently used components of qlib, you can try notebooks here.

The detailed documents are organized in docs. Sphinx and the readthedocs theme is required to build the documentation in html formats.

cd docs/
conda install sphinx sphinx_rtd_theme -y
# Otherwise, you can install them with pip
# pip install sphinx sphinx_rtd_theme
make html

You can also view the latest document online directly.

Qlib is in active and continuing development. Our plan is in the roadmap, which is managed as a github project.

Offline Mode and Online Mode

The data server of Qlib can either deployed as Offline mode or Online mode. The default mode is offline mode.

Under Offline mode, the data will be deployed locally.

Under Online mode, the data will be deployed as a shared data service. The data and their cache will be shared by all the clients. The data retrieval performance is expected to be improved due to a higher rate of cache hits. It will consume less disk space, too. The documents of the online mode can be found in Qlib-Server. The online mode can be deployed automatically with Azure CLI based scripts. The source code of online data server can be found in Qlib-Server repository.

Performance of Qlib Data Server

The performance of data processing is important to data-driven methods like AI technologies. As an AI-oriented platform, Qlib provides a solution for data storage and data processing. To demonstrate the performance of Qlib data server, we compare it with several other data storage solutions.

We evaluate the performance of several storage solutions by finishing the same task, which creates a dataset (14 features/factors) from the basic OHLCV daily data of a stock market (800 stocks each day from 2007 to 2020). The task involves data queries and processing.

  • +(-)D indicates with (out) DatasetCache

Most general-purpose databases take too much time to load data. After looking into the underlying implementation, we find that data go through too many layers of interfaces and unnecessary format transformations in general-purpose database solutions. Such overheads greatly slow down the data loading process. Qlib data are stored in a compact format, which is efficient to be combined into arrays for scientific computation.
