TaLibStandard
A modern and robust C# Technical Analysis library based on the original open-source TA-Lib by Mario Fortier, using Generic Math and supporting Double, Float, and Decimal data types.
📝 Table of Contents
📚 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.
