# 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:
|
|
```bash
|
|
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`](https://qlib.readthedocs.io/en/latest/advanced/serial.html), 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:
|
|
```bash
|
|
python workflow.py dump_and_load_dataset
|
|
``` |
