### Building the feature set
|
||||
|
||||
!! slightly out of date, please refer to templates/FreqaiExampleStrategy.py for updated method !!
|
||||
Features are added by the user inside the `populate_any_indicators()` method of the strategy
|
||||
by prepending indicators with `%`:
|
||||
by prepending indicators with `%` and labels are added by prependng `&`. There are some important
|
||||
components/structures that the user *must* include when building their feature set. As shown below,
|
||||
`with self.model.bridge.lock:` must be used to ensure thread safety - especially when using third
|
||||
party libraries for indicator construction such as TA-lib. Another structure to consider is the
|
||||
location of the labels at the bottom of the example function (below `if set_generalized_indicators:`).
|
||||
This is where the user will add single features labels to their feature set to avoid duplication from
|
||||
various configuration paramters which multiply the feature set such as `include_timeframes`.
|
||||
|
||||
```python

### Building an IFreqaiModel

Freqai has an example prediction model based on the popular `Catboost` regression (`freqai/prediction_models/CatboostPredictionModel.py`). However, users can customize and create

their own prediction models using the `IFreqaiModel` class. Users are encouraged to inherit `train()`, `predict()`,

and `make_labels()` to let them customize various aspects of their training procedures.
