Quantitative TA Library (**QuanTAlib**) is an easy-to-use C# library for quantitative technical analysis with base algorithms, charts, signals and strategies useful for trading securities with [Quantower](https://www.quantower.com/) and other C#-based trading platforms.

**QuanTAlib** is written with some specific design criteria in mind - some reasons why there is '_yet another C# TA library_':

- Written in native C# - no code conversion from TA-LIB or other imported/converted TA libraries
- Supports both **historical data analysis** (working on bulk of historical arrays) and **real-time analysis** (adding one data item at the time without the need to re-calculate the whole history)
- Calculate early data right - no hiding of incomplete calculations with NaN values (unless explicitly requested with useNan: true), data is as valid as mathematically possible from the first value
- Usage of events - each data series is an event publisher, each indicator is a subscriber - this allows seamless data flow between indicators)
- Seamlessly integrates with **Polyglot notebooks** (.NET Interactive) and used in Jupyter notebooks - see the examples and documentation.

QuanTAlib does not focus on sources of OHLCV quotes. There are some basic data feeds available to use in learning and strategy exploration: `RND_Feed` and `GBM_Feed` for random data feed, `Yahoo_Feed` and `Alphavantage_Feed` for quick grab of basic daily data of US stock market.

See [Getting Started](https://github.com/mihakralj/QuanTAlib/blob/main/Docs/getting_started.ipynb) .NET interactive notebook to get a feel how library works. Developers can use QuanTAlib in .NET interactive or in console apps, but the best usage of the library is withing C#-enabled trading platforms - see **QuanTower_Charts** folder for Quantower examples.
