在公众号「python风控模型」里回复关键字：学习资料

TA-Lib，全称“Technical Analysis Library”, 即技术分析库，是Python金融量化的高级库，涵盖了150多种指标，包括股票、期货交易软件中常用的技术分析指标，如MACD、RSI、KDJ、动量指标、布林带等等。

TA-Lib可分为10个子板块：Overlap Studies(重叠指标)，Momentum Indicators(动量指标)，Volume Indicators(交易量指标)，Cycle Indicators(周期指标)，Price Transform(价格变换)，Volatility Indicators(波动率指标)，Pattern Recognition(模式识别)，Statistic Functions(统计函数)，Math Transform(数学变换)和Math Operators(数学运算)，见下图。本文将以系列的形式详细介绍talib技术指标的实现和应用，而本文作为开篇，主要介绍Overlap Studies内容。

二、TaLib安装

注：TaLib是一个pyhon库，故在安装TaLib前需要安装Python。

1. pip安装

（官方安装教程文档：mrjbq7.github.io/ta-lib ）

在命令行下输入命令（在线安装）：

pip install Ta-Lib

（注意：使用pip安装可能会出现这个问题：
error: Microsoft Visual C++ 14.0 is required. Get it with “Microsoft Visual C++ Build Tools”: visualstudio.microsoft.com
****TA-Lib**编写是基于 Cython，因此安装时候需要Microsoft Visual C++ 14.0。**此时就需要手动安装。这个问题在安装其他python第三方包时也可能出现，解决方法与此相同）

2. 手动安装

A. 找到并下载自己需要的对应版本的whl格式文件。
（如：若本机安装是32位的python3.6，则选TA_Lib‑0.4.17‑cp36‑cp36m‑win32.whl下载；
若本机安装的是64位的python2.7，则选择TA_Lib‑0.4.17‑cp27‑cp27m‑win_amd64.whl，其他同理）

下载地址在：
lfd.uci.edu/~gohlke/pyt

B. 在命令行中（命令行的打开方式在文章最后的Tips里），进入此whl文件所在的目录，执行命令：

pip install 下载的whl文件名
如：pip install TA_Lib-0.4.17-cp37-cp37m-win_amd64.whl

C. 或不进入所在目录，直接执行命令：

pip install 文件所在的绝对路径+文件名
如：pip install D:\my_packages\ TA_Lib-0.4.17-cp37-cp37m-win_amd64.whl

3. 检测安装成功

在包安装成功后，命令行界面会有“ Successfully installed TA-Lib ”的提示。

也可通过在命令行输入命令“ pip install ta-lib ”进行检测，如果出现“ Requirement already satisfied: ta-lib in …”（”…“为安装此文件的目录），即表示安装成功。
