FreqAI is a software designed to automate a variety of tasks associated with training a predictive machine learning model to generate market forecasts given a set of input features.

Features include:

  • Self-adaptive retraining - Retrain models during live deployments to self-adapt to the market in a supervised manner
  • Rapid feature engineering - Create large rich feature sets (10k+ features) based on simple user-created strategies
  • High performance - Threading allows for adaptive model retraining on a separate thread (or on GPU if available) from model inferencing (prediction) and bot trade operations. Newest models and data are kept in RAM for rapid inferencing
  • Realistic backtesting - Emulate self-adaptive training on historic data with a backtesting module that automates retraining
  • Extensibility - The generalized and robust architecture allows for incorporating any machine learning library/method available in Python. Eight examples are currently available, including classifiers, regressors, and a convolutional neural network
  • Smart outlier removal - Remove outliers from training and prediction data sets using a variety of outlier detection techniques
  • Crash resilience - Store trained models to disk to make reloading from a crash fast and easy, and purge obsolete files for sustained dry/live runs
  • Automatic data normalization - Normalize the data in a smart and statistically safe way
  • Automatic data download - Compute timeranges for data downloads and update historic data (in live deployments)
  • Cleaning of incoming data - Handle NaNs safely before training and model inferencing
  • Dimensionality reduction - Reduce the size of the training data via Principal Component Analysis
  • Deploying bot fleets - Set one bot to train models while a fleet of follower bots inference the models and handle trades

Quick start

The easiest way to quickly test FreqAI is to run it in dry mode with the following command:

freqtrade trade --config config_examples/config_freqai.example.json --strategy FreqaiExampleStrategy --freqaimodel LightGBMRegressor --strategy-path freqtrade/templates

You will see the boot-up process of automatic data downloading, followed by simultaneous training and trading.

An example strategy, prediction model, and config to use as a starting points can be found in freqtrade/templates/, freqtrade/freqai/prediction_models/, and config_examples/config_freqai.example.json, respectively.

General approach

You provide FreqAI with a set of custom base indicators (the same way as in a typical Freqtrade strategy) as well as target values (labels). For each pair in the whitelist, FreqAI trains a model to predict the target values based on the input of custom indicators. The models are then consistently retrained, with a predetermined frequency, to adapt to market conditions. FreqAI offers the ability to both backtest strategies (emulating reality with periodic retraining on historic data) and deploy dry/live runs. In dry/live conditions, FreqAI can be set to constant retraining in a background thread to keep models as up to date as possible.

An overview of the algorithm, explaining the data processing pipeline and model usage, is shown below.


Important machine learning vocabulary

Features - the parameters, based on historic data, on which a model is trained. All features for a single candle are stored as a vector. In FreqAI, you build a feature data set from anything you can construct in the strategy.

Labels - the target values that the model is trained toward. Each feature vector is associated with a single label that is defined by you within the strategy. These labels intentionally look into the future and are what you are training the model to be able to predict.

Training - the process of "teaching" the model to match the feature sets to the associated labels. Different types of models "learn" in different ways which means that one might be better than another for a specific application. More information about the different models that are already implemented in FreqAI can be found here.

Train data - a subset of the feature data set that is fed to the model during training to "teach" the model how to predict the targets. This data directly influences weight connections in the model.

Test data - a subset of the feature data set that is used to evaluate the performance of the model after training. This data does not influence nodal weights within the model.

Inferencing - the process of feeding a trained model new unseen data on which it will make a prediction.

Install prerequisites

The normal Freqtrade install process will ask if you wish to install FreqAI dependencies. You should reply "yes" to this question if you wish to use FreqAI. If you did not reply yes, you can manually install these dependencies after the install with:

pip install -r requirements-freqai.txt


Catboost will not be installed on arm devices (raspberry, Mac M1, ARM based VPS, ...), since it does not provide wheels for this platform.

Usage with docker

If you are using docker, a dedicated tag with FreqAI dependencies is available as :freqai. As such - you can replace the image line in your docker-compose file with image: freqtradeorg/freqtrade:develop_freqai. This image contains the regular FreqAI dependencies. Similar to native installs, Catboost will not be available on ARM based devices.

Common pitfalls

FreqAI cannot be combined with dynamic VolumePairlists (or any pairlist filter that adds and removes pairs dynamically). This is for performance reasons - FreqAI relies on making quick predictions/retrains. To do this effectively, it needs to download all the training data at the beginning of a dry/live instance. FreqAI stores and appends new candles automatically for future retrains. This means that if new pairs arrive later in the dry run due to a volume pairlist, it will not have the data ready. However, FreqAI does work with the ShufflePairlist or a VolumePairlist which keeps the total pairlist constant (but reorders the pairs according to volume).
