Technical Analysis For Java

Ta4j is an open source Java library for technical analysis. It provides the basic components for creation, evaluation and execution of trading strategies.

Important note: Ta4j was initially developed by Marc de Verdelhan mdeverdelhan. He decided to give up the project, since lack of time. See #192. Many, many thanks for this great work and he made it possible with his work and his time to provide us such a great solution ta4j. So there was a decision to fork the project and to pull it below the top level organisation ta4j. Also the corresponding domain was registered and will be contributed to the ta4j organisation, which hopefully will evolve from the contributors.

• The new corresponding webpage http://ta4j.org will also be initialized in the near future.
  

• The maintenance of ta4j will be continued in this repository

• 100% Pure Java - works on any Java Platform version 8 or later
• More than 130 technical indicators (Aroon, ATR, moving averages, parabolic SAR, RSI, etc.)
• A powerful engine for building custom trading strategies
• Utilities to run and compare strategies
• Minimal 3rd party dependencies
• Simple integration
• One more thing: it's MIT licensed
