📚 Introduction
TaLibStandard is a modern interpretation of the widely used TA-Lib, reimagined in C# 14. It is designed to be reliable, efficient, and user-friendly for developers performing financial market analysis. The addition of .NET's Generic Math feature allows for a richer, more flexible library that can handle a variety of number types.
🎯 Goal
The primary objective of TaLibStandard is to provide a comprehensive, feature-rich and accessible library for conducting technical analysis on financial market data.
🏁 Getting started
To get started with TaLibStandard, you can clone the repository and explore the examples provided in the examples directory. You can also refer to the list of available functions in the documentation for a comprehensive overview of the library's capabilities.
📌 Features
- Support for Double, Float, and Decimal data types, with the help of .NET's Generic Math
- With some basic tests (coverage: >= 80%)
- .NET Exception handling (BREAKING CHANGE)
Roadmap (next features)
- Comprehensive API documentation that is easy to understand
- High-Level API for common use cases
- Support for more data types
- Support for more functions
