python talib库安装与报错解决


TaLib官网:http://ta-lib.org/

Python wrapper for TA-Lib:http://mrjbq7.github.io/ta-lib/doc_index.html

一、TaLib简介

TaLib是一个Python金融指数处理库。包含了很多技术分析里的常用参数指标,例如MA、SMA、WMA、MACD、ATR等。

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:https://mrjbq7.github.io/ta-lib/install.html

  • 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”: https://visualstudio.microsoft.com/downloads/
    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:
https://www.lfd.uci.edu/~gohlke/pythonlibs/

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。

三、TaLib函数介绍

1.        几个指标及其用法演示

注意:talib函数的输入数据需要是Numpy的ndarray 类型,如果数据不是这个类型就需要提前进行类型转换。(“Every function takes the same input, passed as a dictionary of Numpy arrays”)。

在使用tqsdk时,K线及tick序列可以使用to_dataframe()函数将数据序列转化为pandas.DataFrame,即可直接取用其close字段作为talib函数的输入数据了(例如:df_klines=klines.to_dataframe())。

  • SMA (简单移动平均线)(参数1:收盘价序列,参数2:时间周期(均线的计算长度 即 几日均线))

real = SMA(close, timeperiod=30)

例:双均线策略中使用SMA的实例:

https://github.com/shinnytech/tqsdk-python/blob/master/tqsdk/demo/doublema.py

  • ATR(平均真实波幅)
    (参数1:最高价序列,参数2:最低价序列,参数3:收盘价序列,参数4:时间周期)

real = ATR(high, low, close, timeperiod=14)

例:海龟策略中使用ATR的实例:

https://github.com/shinnytech/tqsdk-python/blob/master/tqsdk/demo/turtle.py

  • MACD(异同移动平均线)

macd, macdsignal, macdhist = MACD(close, fastperiod=12, slowperiod=26, signalperiod=9)

  • BBANDS (布林带)

upperband, middleband, lowerband = BBANDS(close, timeperiod=5, nbdevup=2, nbdevdn=2, matype=0)

2.        talib中所有指标函数
