Tulip Indicators


Tulip Indicators is a library of technical analysis functions written in ANSI C.

Lots of information is available on the website: https://tulipindicators.org

High quality bindings are available for Node.js, Python, and .NET.


  • ANSI C with no dependencies.
  • Uses fast algorithms.
  • Easy to use programming interface.
  • Release under LGPL license.


Building is easy. You only need a decent C compiler. Tulip Indicators has no other dependencies.

Just download the code and run make.

git clone https://github.com/TulipCharts/tulipindicators
cd tulipindicators

You should get a static library, libindicators.a. You'll need that library and the header file indicators.h to use Tulip Indicators in your code.
