説明
多くの方からのご要望により、現在、当社の機械学習コードやパッケージのいくつかの例を提供するために懸命に取り組んでいます。
TensorFlow、PyTorch、Keras、Numpy、Pandas、そして多くの.NETパッケージをcTrader内で利用開始できます。
私たちの使命は、cTrader内での機械学習を誰にとってもより簡単にすることです。
ハッピー・ハンティング！
*** このコードは何も取引しません（データを出力するだけです）。これは、当社の機械学習パッケージを使用して独自のAIモデルを作成し始める方法のサンプルコードに過ぎません。

概要
Key functionalities include:
- Data extraction from market bars (open, high, low, close prices, and tick volumes) over a configurable number of bars.
- Conversion of this data into formats compatible with machine learning workflows, including NumSharp NDArrays and Pandas DataFrames.
- Methods to split data into training and testing sets, and to print these datasets for inspection.
- Three operational modes selectable via parameters: DataSplitPrints, PandasPrints, and NDArrayPrints, each demonstrating different data handling approaches.
This sample code aims to facilitate machine learning development inside cTrader by providing foundational examples of data preparation and manipulation using popular ML libraries in a .NET context.
