案例(快速开始)

Similar to TA-Lib, the function interface provides a lightweight wrapper of the exposed TA-Lib indicators.

类似于TA-Lib，函数接口提供了一个暴漏TA-Lib指标的轻量级封装。

Each function returns an output array and have default values for their parameters, unless specified as keyword arguments. Typically, these functions will have an initial "lookback" period (a required number of observations before an output is generated) set to NaN.每个函数都默认需要输入数组，并为它们提供默认值。 参数，除非指定为关键字参数。通常，这些函数 会有一个初步的“lookback”时期(观测所需数量 在生成一个输出之前)，设置为“NaN”。

All of the following examples use the function API:所有的API函数的使用，都需引入库文件：

import numpyimport talib

close = numpy.random.random(100)

计算收盘价的一个简单移动平均数SMA:

output = talib.SMA(close)

计算布林线，三指数移动平均：

from talib import MA_Typeupper, middle, lower = talib.BBANDS(close, matype=MA_Type.T3)

计算收盘价的动量，时间为5：

output = talib.MOM(close, timeperiod=5)

Abstract API Quick Start 抽象 API 快速入门

If you're already familiar with using the function API, you should feel right at home using the abstract API. Every function takes the same input, passed as a dictionary of Numpy arrays:如果您已经熟悉使用函数API，那么您就应该精通使用抽象API。 每个函数有相同的输入，作为一个字典通过NumPy数组：

import numpy as np# note that all ndarrays must be the same length!inputs = {'open': np.random.random(100), 'high': np.random.random(100), 'low': np.random.random(100), 'close': np.random.random(100), 'volume': np.random.random(100)}

函数可以直接导入，也可以用名称实例化：

from talib import abstractsma = abstract.SMAsma = abstract.Function('sma')

调用函数基本上与函数API相同：

from talib.abstract import *output = SMA(input_arrays, timeperiod=25) # SMA均线价格计算收盘价output = SMA(input_arrays, timeperiod=25, price='open') # SMA均线价格计算收盘价upper, middle, lower = BBANDS(input_arrays, 20, 2, 2)slowk, slowd = STOCH(input_arrays, 5, 3, 0, 3, 0) # uses high, low, close by defaultslowk, slowd = STOCH(input_arrays, 5, 3, 0, 3, 0, prices=['high', 'low', 'open'])

Supported Indicators 支持的指标

We can show all the TA functions supported by TA-Lib, either as a list or as a dict sorted by group (e.g. "Overlap Studies", "Momentum Indicators", etc):我们可以显示Ta lib的所有TA函数,返回一个 list 或者 dict
