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
A. 按照首字母排序:
