Wie von vielen von Ihnen gewünscht, arbeiten wir nun intensiv daran, Beispiele für einige unserer Machine-Learning-Codes und -Pakete bereitzustellen.

TensorFlow, PyTorch, Keras, Numpy, Pandas und viele weitere .NET-Pakete, um in cTrader loszulegen.

Unsere Mission ist es, Machine Learning in cTrader für alle einfacher zu machen.

Viel Erfolg bei der Suche!

*** Dieser Code handelt nichts (er gibt nur Daten usw. aus). Es ist einfach Beispielcode, wie Sie mit unseren Machine-Learning-Paketen eigene KI-Modelle erstellen können.
