As requested by many of you, we are now working hard to provide examples of some of our machine learning code and packages.

TensorFlow, PyTorch, Keras, Numpy, Pandas and many more .NET packages to get going inside of cTrader.

Our mission is to make Machine Learning inside cTrader easier for everyone.

Happy hunting!

*** This code does not trade anything (it only prints out data etc). It is simply sample code of how you can start creating your own AI models using our Machine Learning packages.
