查看“TA-Lib”的源代码

TA-Lib（Technical Analysis Library）是一个多平台的[[技术分析]]库，多种编程语言的开源API，包括[[C]]/[[C++]]、[[Java]]、[[Perl]]、[[Python]]版等。包含200多个技术指标，如[[ADX]]、[[MACD]]、[[RSI]]、[[布林带]]等，还支持烛台模式识别。Ta-Lib使用[[BSD]]许可，允许将它集成到您自己的开源或商业应用程序中。

TA-Lib的Python版本是使用 [[SWIG]] 封装C/C++版本的API，难安装，速度稍慢。开源项目[https://github.com/mrjbq7/ta-lib mrjbq7/ta-lib]使用[[Cython]]和[[Numpy]]封装TA-Lib的C/C++版，速度比TA-Lib的Python版快，所以在Python中一般使用该版本。
