High-Frequency Dataset

This dataset is an example for RL high frequency trading.

Get High-Frequency Data

Get high-frequency data by running the following command:

    python workflow.py get_data

Dump & Reload & Reinitialize the Dataset

The High-Frequency Dataset is implemented as qlib.data.dataset.DatasetH in the workflow.py. DatatsetH is the subclass of qlib.utils.serial.Serializable, whose state can be dumped in or loaded from disk in pickle format.

About Reinitialization

After reloading Dataset from disk, Qlib also support reinitializing the dataset. It means that users can reset some states of Dataset or DataHandler such as instruments, start_time, end_time and segments, etc., and generate new data according to the states.

The example is given in workflow.py, users can run the code as follows.

Run the Code

Run the example by running the following command:

    python workflow.py dump_and_load_dataset
