New features under development(order by estimated release time). Your feedbacks about the features are very important.
The high-level framework of Qlib can be found above(users can find the detailed framework of Qlib's design when getting into nitty gritty). The components are designed as loose-coupled modules, and each component could be used stand-alone.
Qlib provides a strong infrastructure to support Quant research. Data is always an important part. A strong learning framework is designed to support diverse learning paradigms (e.g. reinforcement learning, supervised learning) and patterns at different levels(e.g. market dynamic modeling). By modeling the market, trading strategies will generate trade decisions that will be executed. Multiple trading strategies and executors in different levels or granularities can be nested to be optimized and run together. At last, a comprehensive analysis will be provided and the model can be served online in a low cost.
This quick start guide tries to demonstrate
- It's very easy to build a complete Quant research workflow and try your ideas with Qlib.
- 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 | ✔️ | ✔️ | ✔️ |
Python 3.8 | ✔️ | ✔️ | ✔️ |
Python 3.9 | ❌ | ✔️ | ❌ |
Note:
- Conda is suggested for managing your Python environment. In some cases, using Python outside of a
conda
environment may result in missing header files, causing the installation failure of certain packages. - 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 useconda
's Python to installQlib
from source. - 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. Qlib
Requirestables
package,hdf5
in tables does not support python3.9.
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.
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 . # `pip install -e .[dev]` is recommended for development. check details in docs/developer/code_standard_and_dev_guide.rst
Note: You can install Qlib with
python setup.py install
as well. But it is not the recommended approach. It will skippip
and cause obscure problems. For example, only the commandpip install .
can overwrite the stable version installed bypip install pyqlib
, while the commandpython 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.
Tips for Mac: If you are using Mac with M1, you might encounter issues in building the wheel for LightGBM, which is due to missing dependencies from OpenMP. To solve the problem, install openmp first with brew install libomp
and then run pip install .
to build it successfully.
❗ Due to more restrict data security policy. The offical dataset is disabled temporarily. You can try this data source contributed by the community. Here is an example to download the data updated on 20240809.
wget https://github.com/chenditc/investment_data/releases/download/2024-08-09/qlib_bin.tar.gz
mkdir -p ~/.qlib/qlib_data/cn_data
tar -zxvf qlib_bin.tar.gz -C ~/.qlib/qlib_data/cn_data --strip-components=1
rm -f qlib_bin.tar.gz
The official dataset below will resume in short future.
Load and prepare data by running the following code:
# 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 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.
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.

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

Your PR of new Quant models is highly welcomed.
The performance of each model on the Alpha158
and Alpha360
datasets can be found here.
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 theexamples
folder. -
Users can use the script
run_all_model.py
listed in theexamples
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
)
- 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
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.
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
.
Qlib now supports reinforcement learning, a feature designed to model continuous investment decisions. This functionality assists investors in optimizing their trading strategies by learning from interactions with the environment to maximize some notion of cumulative reward.
Here is a list of solutions built on Qlib
categorized by scenarios.
Here is the introduction of this scenario. All the methods below are compared here.
- TWAP
- PPO: "An End-to-End Optimal Trade Execution Framework based on Proximal Policy Optimization", IJCAL 2020
- OPDS: "Universal Trading for Order Execution with Oracle Policy Distillation", AAAI 2021
Dataset plays a very important role in Quant. Here is a list of the datasets built on Qlib
:
Dataset | US Market | China Market |
---|---|---|
Alpha360 | √ | √ |
Alpha158 | √ | √ |
Here is a tutorial to build dataset with Qlib
.
Your PR to build new Quant dataset is highly welcomed.
Qlib is high customizable and a lot of its components are learnable.
The learnable components are instances of Forecast Model
and Trading Agent
. They are learned based on the Learning Framework
layer and then applied to multiple scenarios in Workflow
layer.
The learning framework leverages the Workflow
layer as well(e.g. sharing Information Extractor
, creating environments based on Execution Env
).
Based on learning paradigms, they can be categorized into reinforcement learning and supervised learning.
- For supervised learning, the detailed docs can be found here.
- For reinforcement learning, the detailed docs can be found here. Qlib's RL learning framework leverages
Execution Env
inWorkflow
layer to create environments. It's worth noting thatNestedExecutor
is supported as well. This empowers users to optimize different level of strategies/models/agents together (e.g. optimizing an order execution strategy for a specific portfolio management strategy).
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.
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.
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.

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.
